  2. Description of the Related Art Conventionally, a technique is known in which an acceleration sensor is provided in an electronic key, a movement generated in the electronic key is determined from an output signal of the acceleration sensor, and a vehicle is controlled based on the determination result (see Patent Document 1). Patent Document 1 is a technique for identifying a carrier of an electronic key from movements (such as pace) generated in the electronic key and switching the vehicle environment (seat position, audio setting, etc.) for each user.

JP 2011-57156 A

  As an application example of Patent Document 1, for example, an operation detection in which a specific operation performed by a user using a body is detected by an acceleration sensor of an electronic key, and if the operation is valid, remote operation of the vehicle is permitted or executed. Remote systems are being considered. As an operation detection remote system, when a user performs a specific operation, for example, control of unlocking a vehicle door or opening and closing a slide door is assumed.

  By the way, since the motion detection operation is an operation of moving the body like a gesture, there is a high possibility that the motion will not be correct depending on, for example, the power of the motion or the speed of the operation. However, there is currently no way to know which part of the motion is wrong, so as a user, which part of the motion detection operation is wrong so that the same motion mistake will not be made in the next motion detection operation. There was a need to know.

  An object of the present invention is to provide a motion detection remote system capable of notifying a user of error information when a motion detection operation results in an error.

  The motion detection remote system that solves the above problem detects a motion generated in an electronic key by a motion detection unit provided in the electronic key, and selects an operation target based on a detection signal output from the motion detection unit. In the remote operation configuration, an error monitoring unit that monitors whether or not the motion detection operation is an error by monitoring a detection signal of the motion detection unit, and when the motion detection operation is an error, the error information is stored in a memory. An information holding unit that holds one or more of the error information, and a notification execution unit that notifies the error information using at least one of the operation target, a user terminal, and an electronic key.

  According to this configuration, when an operation error occurs in the motion detection operation, the error information is held in the memory. Based on the error information stored in the memory, the user is notified of the operation error. Therefore, it is possible to notify the user what kind of error the motion detection operation was.

  In the motion detection remote system, the information holding unit preferably holds the error information in a memory of the electronic key. According to this configuration, when writing error information into the memory, it is not necessary to exchange data wirelessly or the like, which is advantageous for writing error information without mistakes.

  In the motion detection remote system, the information holding unit can hold a plurality of error information, and when new error information is received when the maximum amount of error information is held, the oldest one is discarded from the memory. It is preferable to update the memory by holding the new error information in the memory. According to this configuration, the error information written in the memory can be updated, so that the optimum error information can be sequentially held in the memory.

  In the operation detection remote system, it is preferable that the notification execution unit sets the error information to be held in the memory as a condition for executing the notification. According to this configuration, for example, even if an operation error occurs only once accidentally, it is not notified as an operation error, which is advantageous in accurately reporting the operation error.

  In the operation detection remote system, the notification execution unit holds that a plurality of the error information is held in the memory and a plurality of the same or similar error information exists, a condition for executing the notification of the error information, It is preferable to do. According to this configuration, the user is notified as error information only when a plurality of identical or similar operation errors occur. Therefore, it is possible to accurately notify an operation error that is likely to be repeated by the user.

  In the operation detection remote system, the error monitoring unit acquires position information indicating the location where the error occurs, and the information holding unit holds the error information and the position information in association with each other and holds the information in the memory. The notification execution unit preferably notifies the location where the error has occurred based on the position information when executing the notification. According to this configuration, when the error information is notified to the user, the location where the operation error has occurred can be notified. Therefore, it is possible to notify the user of the error information in more detail.

  In the motion detection remote system, the error monitoring unit acquires time information that is an occurrence time when the motion detection operation results in an error, and the information holding unit links the error information and the time information. Preferably, the notification execution unit confirms the occurrence time of the error information based on the time information, and executes the notification of the error information if within a certain time from the occurrence of the error. . According to this configuration, when the error information is notified to the user, it is possible to notify the operation error while determining when the operation error has occurred. Therefore, since an operation error detected in the past can be excluded from the notification, it is advantageous to accurately notify the operation error.

  In the motion detection remote system, a warning selection unit that selects whether or not a warning sound is generated when the motion detection operation results in an error, and an error occurs when the output of the warning sound is effectively selected. It is preferable to include a warning execution unit that generates a warning sound at the time. According to this configuration, it is possible to set whether to output a warning sound when an operation error is detected. Therefore, if the warning sound output is enabled, the user can determine which operation is an operation error. It will be understood accurately.

  In the motion detection remote system, it is preferable that the notification execution unit executes the notification on a display unit in a vehicle when an engine switch of the vehicle is turned on. According to this configuration, when the vehicle engine switch is turned on, for example, the device is turned on, but the device can notify the error information. Therefore, when the boarded user turns on the engine switch, it becomes possible to notify the user of an operation error at an appropriate timing in the flow of the operation process.

  In the motion detection remote system, the notification execution unit displays a selection operation unit for selecting whether to perform the notification on the operation target or a display unit of the user terminal, and displays an operation result of the selection operation unit. Based on this, it is preferable to execute the notification. According to this configuration, when the selection operation unit displayed on the operation target or the display unit of the user terminal is operated, notification of error information is started. Therefore, although the user does not wish, it is not necessary to cause the dark clouds to execute the notification.

  In the operation detection remote system, it is preferable that the notification execution unit displays the selection operation unit on the display unit for a certain period of time. According to this configuration, since the selection operation unit is displayed for a certain time, the selection operation unit can be displayed only in a necessary time zone.

  In the motion detection remote system, the detection signal of the motion detection unit has a plurality of different types of feature amounts in the signal waveform, and the error monitoring unit, when the feature amount matches only a certain number, It is preferable to recognize that the motion detection operation is an error. According to this configuration, it is possible to determine the presence / absence of an operation error by a simple determination of confirming whether the feature amount is correct in the detection signal output from the motion detection unit.

  In the motion detection remote system, the notification execution unit allows the user to select whether or not there is an operation history when notifying the error information, and when it is selected that there is an operation history, the notification of the motion detection operation is performed as the notification. When the operation advice is executed and it is selected that the user does not remember the operation, the alert is preferably executed as the notification. According to this configuration, it is possible to notify two types of operation advice and alerting as operation error notifications.

  According to the present invention, it is possible to notify a user of error information when a motion detection operation results in an error.

Hereinafter, an embodiment of the motion detection remote system will be described with reference to FIGS.
As shown in FIG. 1, an operation target of the electronic key 1 (hereinafter referred to as a vehicle 2) includes an electronic key system 3 that performs ID collation with the electronic key 1 wirelessly. The electronic key system 3 is preferably a key operation free system that executes ID collation by narrow-band radio (communication distance: several m) triggered by communication from the vehicle 2. Hereinafter, ID verification in the key operation free system is referred to as “smart verification”, and the communication is referred to as “smart communication”.

  The vehicle 2 includes a verification ECU (Electric Control Unit) 4 that performs various verifications with the electronic key 1, a body ECU 5 that manages the power supply of the on-vehicle electrical components, and an engine ECU 6 that controls the operation of the engine 7. These ECUs are electrically connected through a communication line 8 in the vehicle. The electronic key ID of the electronic key 1 registered in the vehicle 2 is written and stored in the memory 9 of the verification ECU 4. The vehicle 2 includes an in-vehicle transmitter 10 that transmits radio waves to the electronic key 1 outside the vehicle, an in-vehicle transmitter 11 that transmits radio waves to the electronic key 1 in the vehicle, and a vehicle receiver that receives radio waves transmitted from the electronic key 1. 12 is preferable. These wireless devices are connected to the verification ECU 4. The radio waves that can be transmitted by the external transmitter 10 and the in-vehicle transmitter 11 are preferably radio waves having a frequency in the LF (Low Frequency) band, for example. For example, it is preferable that the vehicle exterior transmitter 10 includes a driver seat side vehicle exterior transmitter 10a disposed on the driver seat side and a passenger seat side vehicle exterior transmitter 10b disposed on the passenger seat side. The radio wave that can be received by the vehicle receiver 12 is preferably a radio wave having a frequency in the UHF (Ultra High Frequency) band, for example. The body ECU 5 controls the operation of the door lock mechanism 13 that locks and unlocks the vehicle door. The verification ECU 4 is connected to an engine switch 14 that is operated when switching the power supply state (IG off, ACC on, IG on, engine start) of the vehicle 2. The engine switch 14 is a so-called ignition switch, and is preferably, for example, a push momentary switch disposed in the driver's seat.

  The electronic key 1 includes a key control unit 15 that controls the operation of the electronic key 1, a reception unit 16 that can receive radio waves transmitted from the vehicle 2, and a transmission unit 17 that can transmit radio waves to the vehicle 2. The receiving unit 16 and the transmitting unit 17 are electrically connected to the key control unit 15. An electronic key ID, which is an ID unique to the key, is written and stored in the memory 18 of the key control unit 15. The receiving unit 16 is preferably capable of receiving, for example, LF radio waves. The transmission unit 17 is preferably capable of transmitting UHF radio waves, for example.

  The vehicle exterior transmitter 10 transmits the request signal Srq LF around the vehicle body outside the vehicle. The in-vehicle transmitter 11 transmits the request signal Srq to the entire area of the vehicle by LF. When the electronic key 1 is located outside the vehicle, the electronic key 1 is activated by receiving the request signal Srq of the in-vehicle transmitter 10, and when it is located in the vehicle, the electronic key 1 is activated by receiving the request signal Srq of the in-vehicle transmitter 11. The signal Sid is transmitted to the vehicle 2 by UHF. The ID signal Sid is a signal including at least the electronic key ID registered in the electronic key 1. When the ID signal Sid is received by the vehicle receiver 12 from the electronic key 1 outside the vehicle, the verification ECU 4 performs smart verification outside the vehicle, and when the ID signal Sid is received by the vehicle receiver 12 from the electronic key 1 inside the vehicle, the verification ECU 4 performs the smart verification inside the vehicle. Do. When the verification ECU 4 confirms that the smart verification outside the vehicle is established, the body ECU 5 permits or executes the locking / unlocking of the vehicle door. Operation).

  The electronic key system 3 reads a specific movement performed by a user carrying the electronic key 1 (an operation action with a characteristic movement using the body) by the movement detection unit 19 built in the electronic key 1, thereby Is provided with a remote operation function (operation detection remote system 20). The operation action accompanied by the characteristic movement by the user is preferably an operation that repeats the action using the body a plurality of times, for example, in the vicinity of the vehicle 2. As an operation using the body, for example, there is an act of hitting the ground multiple times with the heel.

  The motion detector 19 is preferably an acceleration sensor (G sensor), for example. The motion detection unit 19 constantly monitors the movement (acceleration) generated in the electronic key 1 and outputs a detection signal Smt to the key control unit 15. Note that, for example, the motion detection unit 19 may normally be asleep, and may be activated when the amount of change in acceleration exceeds a predetermined value.

  The electronic key 1 includes a motion determination unit 21 that determines the legitimacy of the motion detection operation based on the detection signal Smt of the motion detection unit 19, and an operation target device of the electronic key 1 (for example, in-vehicle) when the motion detection operation is valid. It is preferable to include a remote control unit 22 that transmits radio waves for controlling the device from the transmission unit 17 to remotely operate the device. The movement determination unit 21 and the remote control unit 22 are preferably provided in the key control unit 15, for example. Examples of the in-vehicle device that is the target of the motion detection operation include a door lock of a vehicle door and an engine 7.

  FIG. 2 illustrates a specific example of motion determination. When the user holding the electronic key 1 performs a legitimate motion detection operation, the waveform of the detection signal Smt output from the motion detection unit 19 is a waveform according to the motion. For example, when it is a valid motion detection operation to repeat a certain motion twice, the feature amount of the detection signal Smt that is a motion determination parameter is that the amplitude of the detection signal Smt in each motion has a specified value V1 or more. The time required for the first movement operation is within the specified time T1, the time required for the second movement operation (total time) is within the specified time T2, In some cases, the waveform area of negative amplitude (shaded area in the figure) is greater than or equal to the specified values S1, S2 (<S1), S3 (<S2). The motion determination unit 21 recognizes that the motion detection operation has started when it first confirms that the amount of change (the slope of the waveform) of the detection signal Smt of the motion detection unit 19 is equal to or greater than a specified value from the state of no motion. Under this state, if all the feature quantities that can determine the movement satisfy the requirements, it is determined that the movement generated in the electronic key 1 is valid.

  The motion determination unit 21 transmits a device operation request to the remote control unit 22 when determining that the motion detection operation is valid. When receiving a device operation request from the motion determination unit 21, the remote control unit 22 causes the transmission unit 17 to transmit a device control signal Swl that requests the vehicle 2 to operate the device. For example, the device control signal Swl is a signal including a command for requesting the operation of the target device and the electronic key ID registered in the electronic key 1. When the verification ECU 4 receives the device control signal Swl from the electronic key 1, the verification ECU 4 confirms the validity of the electronic key ID in the device control signal Swl. If the validity of the electronic key ID can be confirmed, the verification ECU 4 sends a command included in the same signal. Control the equipment by operating on the basis.

  As shown in FIG. 1, the motion detection remote system 20 includes an error reason notification function for notifying a user of an error reason when a motion detection operation results in an error. For example, the error reason notification function is an advice function for notifying the user where the motion operation is different, or a notification that notifies the user that the motion performed by the user is not intended and matches the motion that follows the motion detection operation. It is preferable to provide an arousing function.

  The motion detection remote system 20 preferably includes an error monitoring unit 23 that monitors whether an error has occurred in the motion detection operation, and an information holding unit 24 that holds error information Der when an operation error has occurred. . The error monitoring unit 23 and the information holding unit 24 are preferably provided in the key control unit 15, for example. The error monitoring unit 23 recognizes that an error has occurred in the motion detection operation when the motion determination unit 21 recognizes the start of the motion detection operation but one parameter is not satisfied during the determination. The information holding unit 24 holds in the memory 18 as error information Der what kind of error has occurred in the motion detection operation. The information holding unit 24 causes the memory 18 to include one or more detected error information Der.

  The motion detection remote system 20 preferably includes an information notification unit 25 that transmits the error information Der held in the memory 18 from the transmission unit 17 to the operation target of the electronic key 1 (for example, the vehicle 2). The information notification unit 25 is preferably provided in the key control unit 15, for example. The information notification unit 25 preferably transmits the error information Der to the vehicle 2 in the process of smart communication.

  The operation detection remote system 20 preferably includes a notification execution unit 26 that executes a notification operation based on the error information Der. For example, the notification execution unit 26 is preferably provided in the verification ECU 4. For example, it is preferable that the notification execution unit 26 acquires the error information Der from the electronic key 1 by communication and executes the error information Der by a display unit in the vehicle. This display unit preferably uses, for example, a display of a car navigation system in the vehicle.

  The motion detection remote system 20 includes a warning selection unit 27 for selecting whether or not to generate a warning sound when a motion detection operation results in an error, and when an error occurs when the output of the warning sound is effectively selected. It is preferable to include a warning execution unit 28 that generates a warning sound. The warning selection unit 27 and the warning execution unit 28 are preferably provided in the verification ECU 4, for example. The warning selection unit 27 preferably causes the user to select whether the warning is valid or invalid in the vehicle 2. The warning execution unit 28 sets the electronic key 1 in a state in which a warning operation can be executed, for example, by transmitting a warning sound valid switching request to the electronic key 1 by communication.

Next, the operation of the error reason notification function of the operation detection remote system 20 will be described with reference to FIGS.
FIG. 3 shows the waveform of the detection signal Smt when an operation error occurs. This figure shows an example in which the time T ′ required for the first motion operation exceeds the specified time T1, that is, an example in which the operation speed of the first motion operation is slower than normal. The error monitoring unit 23 recognizes an operation error that the operation speed of the first movement operation is slower than the normal speed by confirming that the time of the first movement operation exceeds the specified time T1. The error monitoring unit 23 outputs a monitoring result that the operation speed of the first movement operation is low to the information holding unit 24.

  FIG. 4 shows a specific example of the error information Der written in the memory 18. For example, the error information Der is preferably constructed from an information group in which an error state is written for each feature quantity that is a parameter for motion determination. Specifically, a column 29 for writing whether the first motion operation is small or large, a column 30 for writing whether the time of the first motion operation is short or long, and a column for writing whether the second motion operation is small or large It is preferable to provide a column 32 for writing whether the time of the first and second movement operations is short or long. For example, a binary code “0” is preferably written when the motion operation is small or short, and a binary code “1” is written when the motion operation is large or long.

  The information holding unit 24 holds one or more error information Der in the memory 18 by storing the error monitoring result in the memory 18 each time a new error monitoring result is input from the error monitoring unit 23. That is, even when a plurality of operation errors are detected, these can be held in the memory 18. When the new error information Der is input when the maximum error information Der that can be held is already held in the memory 18, the information holding unit 24 discards the oldest error information Der and releases the latest error information Der. The memory 18 is updated by fetching.

  FIG. 5 illustrates a specific communication sequence of smart communication (for example, in-car smart communication). When the in-vehicle transmitter 11 detects the opening operation of the vehicle door using, for example, a door courtesy switch and determines that the electronic key 1 has entered the vehicle, the in-vehicle transmitter 11 intermittently LF-transmits the wake signal Swk from the in-vehicle transmitter 11 into the vehicle. Execute smart communication in the car. The electronic key 1 is activated when it receives the wake signal Swk, and transmits the ACK signal Sack1 to the vehicle 2 by UHF. When the verification ECU 4 can receive the ACK signal Sack1 within a predetermined time after transmitting the wake signal Swk, the verification ECU 4 transmits the vehicle code Svi, which is the unique ID of the vehicle 2, from the in-vehicle transmitter 11 to the electronic key 1 by LF. 1 makes vehicle code collation. When the electronic key 1 confirms that the vehicle code verification is established, the electronic key 1 transmits an ACK signal Sack2 to the vehicle 2 by UHF.

  When the verification ECU 4 can receive the ACK signal Sack2 within a predetermined time after transmitting the vehicle code Svi, the verification ECU 4 performs challenge response authentication by LF transmitting the challenge signal Sch from the in-vehicle transmitter 11 to the electronic key 1. For example, the challenge signal Sch is a signal including a challenge code whose code is changed every time transmission is performed and a key number indicating what number key is registered in the vehicle 2. When the electronic key 1 receives the challenge signal Sch, the key number is first verified, and if the key number verification is established, the response code is calculated by passing the challenge code through the encryption key of the electronic key 1.

  After calculating the response code, the electronic key 1 transmits a response signal Srs to the vehicle 2 by UHF. At this time, the information notification unit 25 preferably transmits all the error information Der held in the memory 18 to the vehicle 2 on the response signal Srs. Therefore, the response signal Srs is preferably a signal including a response code calculated by the electronic key 1, an electronic key ID registered in the electronic key 1, and all error information Der held in the memory 18. . When the error information Der is not held in the memory 18, the response signal Srs is transmitted as a signal including only the response code and the electronic key ID.

  When the verification ECU 4 can receive the response signal Srs within a predetermined time after transmitting the challenge signal Sch, the verification ECU 4 executes response verification and electronic key ID verification. The response verification is verification for comparing the response code received from the electronic key 1 with the response code calculated in the same manner by the verification ECU 4. The electronic key ID verification is a verification for comparing the electronic key ID received from the electronic key 1 with the electronic key ID registered in the verification ECU 4. When the verification ECU 4 confirms that these verifications are established, the verification ECU 4 processes the in-vehicle smart verification as establishment.

  As illustrated in FIG. 6, the notification execution unit 26 performs motion detection operation advice, alerting, or the like on the operation target (for example, the vehicle 2) based on the error information Der received from the electronic key 1. Operation advice and alerting are preferably executed on the screen 33 of the car navigation system, for example. It is preferable that the notification screen 34 for operation advice and alerting is notified only for a certain period of time, for example. Various combinations of operation advice and alerting may be possible, such as visual notification on the notification screen 34, audible audio notification, or both. The notification execution unit 26 notifies operation advice and alerting according to the error information Der received from the electronic key 1. When there are a plurality of error information Der, the notification execution unit 26 may display the error information Der on the screen at once or selectively display the error information Der.

  The notification execution unit 26 may be able to execute advice and alert notifications on condition that there are a plurality of error information Der received from the electronic key 1. In this case, when the operation error occurs only once accidentally, the notification of the error information Der is not executed, so that unnecessary notification need not be executed.

  Further, the notification execution unit 26 may operate to notify the error information Der on the condition that there are a plurality of operation errors having the same or similar contents. For example, when a plurality of operation errors with a small first movement operation occur, the user is notified that the first movement operation is insufficient in speed. In this case, if the same or similar operation error does not occur a plurality of times, advice or alerting is not notified, which is more advantageous for performing accurate notification.

  For example, when the engine switch 14 of the vehicle 2 is operated to IG on (ACC on is also possible), the notification execution unit 26 may execute notification of the error information Der. In this case, when the engine switch 14 is IG-on (ACC on is also possible), the car navigation system screen 33 is also turned on. At the same time, the error information Der is displayed on the car navigation system screen 33. Notification can be made. Therefore, it is possible to smoothly notify the error information Der to a user who gets on and starts the engine 7.

  As shown in FIG. 7, for example, when the electronic key 1 is provided with a communication unit 36 that can communicate with the user terminal 35 possessed by the user, the error information Der can be displayed on the user terminal 35. The user terminal 35 is preferably a high function mobile phone, for example. Moreover, it is preferable to use short-range wireless communication for communication between the electronic key 1 and the user terminal 35, for example. The near field communication is preferably NFC (Near Field Communication), for example.

  In order to display the error information Der on the user terminal 35, an operation of holding the user terminal 35 over the electronic key 1 is performed. If the electronic key 1 can be confirmed to be the user terminal 35 paired with itself in the short-range wireless communication, the electronic key 1 transmits the error information Der held in the memory 18 to the user terminal 35 by the short-range wireless communication. The user terminal 35 displays the error information Der received from the electronic key 1 on the screen 37 of the user terminal 35, thereby notifying the user of operation advice and alerting on the user terminal 35. When the user terminal 35 receives the error information Der from the electronic key 1, the user terminal 35 does not immediately display the error information Der on the screen. For example, when the user terminal 35 is operated from the standby state to the activated state, the error information It is preferable to operate so as to display the error information Der within a certain period of time after receiving Der.

  As shown in FIG. 8, the error information Der may include position information Dps that indicates where the operation error has occurred in the vehicle 2. In this case, the out-of-vehicle transmitter 10 (FIG. 8 shows the passenger-side out-of-passenger transmitter 10b) transmits position information Dps indicating the position of the transmitter at the time of smart communication. The position information Dps is preferably information that can be notified from which of the in-vehicle transmitters 10a and 10b the radio wave is transmitted. That is, the position information Dps transmitted from the driver's seat side outside transmitter 10a includes information notifying that it has been transmitted from the driver's seat side, and the position information Dps transmitted from the passenger seat side outside transmitter 10b is the passenger's seat side. Contains information notifying that it has been sent from. The position information Dps may be transmitted from the vehicle 2 to the electronic key 1 at any time during the communication process of smart communication. When the information holding unit 24 confirms that an operation error has occurred, the information holding unit 24 holds the position information Dps received in the smart communication in the established state at that time in association with the error information Der and holds it in the memory 18.

  The information notification unit 25 transmits a pair of error information Der and position information Dps to the vehicle 2 in a communication process of in-vehicle smart communication at a certain in-vehicle smart communication. Upon receiving the pair of error information Der and position information Dps, the notification execution unit 26 notifies the user of the error information Der in association with the position where the operation error has occurred.

  FIG. 9 illustrates an example of the error information Der notification screen 34. As shown in the figure, the notification executing unit 26 preferably displays a selection operation unit 38 for selecting whether or not to execute notification on the operation target display unit when the error information Der is notified. The display unit is preferably a screen 33 of a car navigation system, for example. The notification execution unit 26 preferably displays the selection operation unit 38 on the display unit for a certain period of time. The selection operation unit 38 is preferably a display button on the notification screen 34, for example. For example, the selection operation unit 38 includes a first selection operation unit (announcement notification button) 38a that is operated when there is an operation history, and a second selection operation unit (attention notification button) 38b that is operated when there is no operation history. It is preferable that Various methods can be applied to the selection operation unit 38, such as a method of operating a touch panel or a method of operating another determination button in conjunction with a cursor on the screen.

  When the notification execution unit 26 confirms that the first selection operation unit 38a has been operated, the notification guide unit 26 displays an operation guide screen 39 on the screen 33 of the car navigation system. When the notification execution unit 26 confirms that the second selection operation unit 38b has been operated, for example, an alerting screen 40 such as “the operation performed near the passenger seat before boarding may be erroneously recognized”. Is displayed on the screen 33 of the car navigation system.

  As shown in FIG. 9, when the warning selection unit 27 displays a warning screen 40 on the display unit, for example, an effective / invalid operation unit 41 for selecting whether to output the warning sound is displayed on the screen 40. It is preferable. The valid / invalid operation unit 41 is preferably a display button on the screen, for example. When the warning selection unit 27 confirms that the valid / invalid operation unit 41 is operated on the alerting screen 40, the warning selection unit 27 sets the output of the warning sound to be valid.

  As shown in FIG. 10, when the warning execution unit 28 confirms that the output of the warning sound is set to be valid, the warning execution unit 28 transmits a warning sound valid switching request to the electronic key 1 by communication, for example. The warning sound valid switching request may be transmitted to the electronic key 1 immediately when the valid / invalid operation unit 41 is operated, or may be transmitted to the electronic key 1 in the communication process of the next smart communication. In any case, when the electronic key 1 receives the warning sound valid switching request from the vehicle 2, the electronic key 1 enters an operation state in which the warning sound can be notified. At this time, if a warning sound is generated in the vehicle 2, when the error information Der is detected, it is transmitted to the vehicle 2 to notify the vehicle 2 that an operation error has occurred. Further, if a warning sound is generated with the electronic key 1, the electronic key 1 is notified when an operation error is detected with the electronic key 1.

  As illustrated in FIG. 11, the error information Der may include time information Dtm that is a generation time when the motion detection operation results in an error. For example, the out-of-vehicle transmitter 10 (FIG. 11 shows the passenger side out-of-passenger transmitter 10b) transmits time information Dtm of the current time during smart communication. The time information Dtm is preferably obtained from a timer (clock) mounted on the vehicle. The time information Dtm may be transmitted from the vehicle 2 to the electronic key 1 at any time in the communication course of smart communication. When the information holding unit 24 confirms that an operation error has occurred, the information holding unit 24 holds the time information Dtm received in the established smart communication at that time in association with the error information Der and holds it in the memory 18.

  The information notification unit 25 transmits a pair of error information Der and time information Dtm to the vehicle 2 in the communication process of smart communication during certain in-vehicle smart communication. When the notification execution unit 26 receives the pair of error information Der and time information Dtm, if the time determined from the time information Dtm is within a certain time, the notification execution unit 26 notifies the user of the error information Der. By doing so, it is not necessary to notify the error information Der acquired in the past (for example, one day ago), which is further advantageous in ensuring notification accuracy.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) By checking the feature quantity of the detection signal Smt output from the motion detection unit 19, it is determined whether or not the motion detection operation is an operation error. When the operation error is determined, the error information Der is electronic It is held in the memory 18 of the key 1. Then, the error information Der is notified to notify the user of specific error contents. Therefore, it is possible to notify the user of what kind of error the motion detection operation was.

  (3) A plurality of error information Der can be written in the memory 18, and when new error information Der is acquired when the maximum number of error information Der has been written in the memory 18, the oldest error information Der is discarded. The newly fetched error information Der is written in the memory 18. Therefore, the memory 18 can be updated, and the optimum error information Der can be sequentially held in the memory 18.

  (4) The notification of the error information Der may be executed on the condition that a plurality of error information Der is held in the memory 18. Therefore, for example, even if an operation error occurs only once accidentally, it is not necessary to notify the operation error as an operation error, which is advantageous in accurately reporting the operation error.

  (5) Notification of error information Der may be executed on condition that a plurality of identical or similar operation errors occur. Therefore, it is possible to accurately notify an operation error that is likely to be repeated by the user.

  (6) The positional information Dps is included in the radio wave transmitted during smart communication from the external transmitter 10 (in-vehicle transmitter 11), and when an operation error occurs in the motion detection operation, the positional information Dps received at that timing Is linked to the error information Der and held in the memory 18. When the operation error is notified, the position where the operation error has occurred is also notified based on the position information Dps held in the memory 18. Therefore, the error information Der can be notified to the user in more detail.

  (7) Time information Dtm is included in the radio wave transmitted during smart communication from the external transmitter 10 (in-vehicle transmitter 11), and when an operation error occurs in the motion detection operation, the time information Dtm received at that timing Is linked to the error information Der and held in the memory 18. Then, at the time of notification of the operation error, based on the time information Dtm held in the memory 18, if the operation error has occurred within a certain period of time, the notification of the operation error is executed. Therefore, since an operation error detected in the past can be excluded from the notification, it is advantageous to accurately notify the operation error.

  (8) The valid / invalid operation unit 41 for selecting valid / invalid of the output of the warning sound is displayed on the screen 33 (warning screen 40) of the car navigation system. Therefore, since it is possible to set whether or not a warning sound is output when an operation error is detected, if the warning sound output is enabled, the user can be immediately notified which operation is an error operation. it can.

  (9) When the engine switch 14 of the vehicle 2 is turned on, an operation error notification is automatically displayed on the screen 33 of the car navigation system. By the way, when the engine switch 14 is turned on, each device of the vehicle 2 is turned on, and the car navigation system is also turned on. Therefore, when the boarded user turns on the engine switch 14, an operation error can be notified to the user at a suitable timing in the flow of the operation process.

  (10) The selection operation unit 38 for selecting whether or not to execute the error notification operation is displayed on the screen 33 (notification screen 34) of the car navigation system, and the operation is performed when the selection operation unit 38 is operated. Start error notification. Therefore, although the user does not wish, it is not necessary to cause the dark clouds to execute the notification.

  (11) The selection operation unit 38 is displayed on the notification screen 34 for a certain time, and is switched to non-display after the certain time has elapsed. Therefore, the selection operation unit 38 can be displayed only in a necessary time zone.

  (12) Whether the motion detection operation is correct or not is determined by whether or not these take a normal value in a plurality of feature amounts in the detection signal Smt. Therefore, the presence or absence of an operation error can be determined by a simple determination of confirming whether the feature amount of the detection signal Smt is correct.

  (13) The first selection operation unit 38a and the second selection operation unit 38b are provided on the notification screen 34. When the first selection operation unit 38a is operated, the error information Der is notified as operation advice, and the second selection operation unit When 38b is operated, error information Der is notified as a warning. Therefore, the user can be notified of two types of operation advice and alerting.
