Description

  The present invention relates to an input device for an in-vehicle device that controls reception of an input signal according to an operator who has performed an input operation.

  Many car audio and car navigation systems equipped on a vehicle are controlled so as not to accept operation signals received during traveling.

  In such car audio and car navigation, for example, a detection signal is received from a vehicle speed sensor, a parking drive sensor, a side brake sensor, or the like, and it is determined whether or not the vehicle is running based on the received detection signal. When the vehicle is running, control is performed so as not to accept an operation signal from the input device.

  Therefore, while the vehicle is traveling, not only the driver but also a passenger other than the driver who is on the vehicle cannot operate the operation target devices such as car audio and car navigation.

  Therefore, in Patent Document 1, first and second switches are provided on the left and right sides of the steering wheel of the vehicle, and when the first and second switches are operated simultaneously, the prohibition state of the input operation is released. A vehicle display device has been proposed.

In Patent Document 2, the first and second stress sensors are provided on the left and right portions of the steering wheel, respectively, and the driver's left and right hands are on the steering wheel while the vehicle is running. The first and second stress sensors indicate that at least one of the left and right hands of the driver is not on the steering wheel. In such a case, a car navigation device has been proposed in which the reception of at least a part of the operation input from the input receiving unit is prohibited.

≪Action≫
A processing procedure in the remote control unit 3 of the navigation device 1 to which the input device of the in-vehicle device according to the present embodiment is applied will be described.

  FIG. 3 is a flowchart showing a processing procedure in the remote control unit 3 of the navigation device 1 to which the input device of the in-vehicle device according to the present embodiment is applied.

  First, when the operator performs an input operation, the operation signal generation means 33 of the remote control unit 3 generates an operation signal and supplies it to the CPU 34. Then, when the operation signal is supplied from the operation signal generation unit 33 (step S101), the CPU 34 causes the contact detection unit 32 to detect the hand touched by the operator. Specifically, the CPU 34 requests the contact detection means 32 to detect the coordinate information of the contact portion of the hand touched by the operator as a contact pattern and supply the detected contact pattern.

  When the contact detection unit 32 is requested to supply the contact pattern, the contact detection unit 32 performs detection using the coordinate information of the contact part of the hand touched by the operator as the contact pattern, and if detected (step S102), the process is performed as a step. If the process proceeds to S103 and cannot be detected, the process proceeds to step S105.

  FIG. 4A is an explanatory diagram illustrating an example of a contact pattern of a contact portion of the right hand detected by the contact detection unit 32, and FIG. 4B is a left hand contact detected by the contact detection unit 32. It is explanatory drawing explaining an example of the contact pattern of the part.

  As shown in FIG. 4 (a), the contact surface 60 of the right hand thumb base, the contact surface 61 of the right index finger, the contact surface 62 of the right middle finger, the contact surface 63 of the right hand ring finger, and the contact surface 64 of the right hand little finger Has been detected. Similarly, as shown in FIG. 4B, the contact surface 66 of the left hand thumb base, the contact surface 67 of the left index finger, the contact surface 68 of the left middle finger, the contact surface 69 of the left hand ring finger, and the contact of the left hand little finger. A surface 70 is detected.

  Next, the right hand / left hand determination unit 34a of the CPU 34 performs a determination process as to whether the contact pattern detected by the contact detection unit 32 indicates the right hand or the left hand. Specifically, all the right hand patterns and left hand patterns stored in the contact pattern storage unit 35 are read out, and the contact pattern detected by the contact detection unit 32 is any of the read out right hand patterns or left hand patterns. Whether the pattern is similar to the right hand pattern or the left hand pattern is determined by pattern matching.

  If it is determined that the contact pattern detected by the contact detection unit 32 is similar to both the right hand pattern and the left hand pattern, the process proceeds to step S105.

  Next, when the right hand / left hand determining unit 34a of the CPU 34 determines that the contact pattern detected by the contact detecting unit 32 is similar to either the right hand pattern or the left hand pattern (step S103), the contact detecting unit 32 When the detected contact pattern is similar to the read right hand pattern, it is determined that the hand operated by the operator is the right hand, and when the contact pattern is similar to the read left hand pattern, the operation is performed. It is determined that the hand operated by the person is the left hand. Then, a right / left hand determination signal indicating the determination result is generated and added to the remote control transmission signal (step S104).

  Next, the CPU 34 adds the operation signal generated by the operation signal generation means 33 to the remote control transmission signal (step S105).

  On the other hand, when the contact detection unit 32 cannot detect the contact pattern in step 102, or in step S103, it can be determined whether the contact pattern detected by the contact detection unit 32 is similar to the read right hand pattern or the left hand pattern. Even if not, the operation signal generated by the operation signal generation means 33 is added to the remote control transmission signal (step S105).

  Next, the transmission means 31 transmits the remote control transmission signal added in step S105 (step S106).

  Next, a processing procedure in the information processing unit 5 of the navigation device 1 to which the input device of the in-vehicle device according to the present embodiment is applied will be described.

  FIG. 5 is a flowchart illustrating a processing procedure in the information processing unit 5 of the navigation device 1 to which the input device of the in-vehicle device according to the present embodiment is applied.

  First, the travel information determination means 51a of the CPU 51 of the information processing unit 5 determines whether or not the mounted vehicle is traveling (step S201). Specifically, the travel information determination unit 51a receives the vehicle rotation direction and speed information detected by the gyro sensor 22 and the speed sensor 23 of the travel information detection unit 2 and the current location information detected by the GPS sensor 21. Then, it is determined whether or not the mounted vehicle is traveling from the received rotation direction information, speed information, and current location information. When the travel information determination unit 51a determines that the host vehicle is traveling, the CPU 51 proceeds to step S202.

  Next, when the receiving unit 43 of the user interface unit 4 receives the remote control transmission signal transmitted by the remote control unit 3, the receiving unit 43 supplies the received remote control transmission signal to the information processing unit 5. Then, the CPU 51 of the information processing unit 5 determines whether or not a right hand / left hand determination signal indicating whether the hand operated by the operator is the right hand or the left hand is added to the supplied remote control transmission signal. (Step S202).

  When the CPU 51 determines that the right hand / left hand determination signal is added to the received remote control transmission signal, the operating hand determination means 51b indicates that the added right hand / left hand determination signal is the door of the passenger seat. It is determined whether the hand on the side or the hand on the door side of the driver's seat is indicated (step S203).

  Specifically, the operating hand determination unit 51b is configured such that when the mounted vehicle is a right-hand drive vehicle and the right-hand left-hand determination signal indicates a left hand, or the mounted vehicle is a left-hand drive vehicle and the right-hand left-hand determination signal is When the right hand is indicated, it is determined that the right hand / left hand determination signal indicates the hand on the door side of the passenger seat. On the other hand, the operating hand determination means 51b indicates that the mounted vehicle is a right-hand drive vehicle and the right-hand left-hand determination signal indicates a right hand, or the mounted vehicle is a left-hand drive vehicle and the right-hand left-hand determination signal indicates a left hand. If it is determined that the right hand / left hand determination signal indicates a hand on the door side of the driver's seat.

  When the operation hand determination unit 51b determines that the added right hand / left hand determination signal indicates a hand on the door side of the driver's seat, the operation signal determination unit 51c is added to the remote control transmission signal. An operation signal can be input.

  Next, the input / output control means 53 controls, for example, the display means 42 based on the operation signal added to the remote control transmission signal which is allowed to be input (step 204).

  In step S201, when the travel information determination unit 51a determines that the mounted vehicle is not traveling, the input / output control unit 53 operates the operation signal added to the remote control transmission signal received by the reception unit 43. For example, the display means 42 is controlled based on (step 204).

  FIG. 6 is an explanatory diagram illustrating an outline of operation of the navigation device 1 to which the input device of the in-vehicle device according to the present embodiment mounted on the right-hand drive vehicle is applied.

  As shown in FIG. 6, a center console 7 is provided at a central portion in the mounted vehicle, and the user interface of the navigation device 1 to which the input device of the in-vehicle device according to the present embodiment is applied in the center console 7. The unit 4 and the information processing unit 5 are arranged.

Then, the remote control unit 3 transmits a remote control transmission signal at an angle θ ₂ having a relatively narrow directivity angle. Here, the remote control unit 3L and the remote control unit 3R shown in FIG. 6 have the same configuration as the remote control unit 3, and for the sake of explanation, the remote control unit 3 at the position on the passenger seat side is remotely controlled. The remote control unit 3 is shown as a part 3L, and the remote control unit 3 at the position on the driver's seat side is shown as a remote control unit 3R.

Further, in FIG. 6, a remote control transmission signal processing unit 5 that has been transmitted to the receiving angle which can receive remote control transmission signal is indicated by the angle theta _1, the information processing unit 5 from the range of the angle theta ₁ Can be received.

Therefore, for example, the remote control unit 3L at the position of the passenger seat side, so located within the range of the angle theta _1, the information processing unit 5 can receive the remote control signal transmitted from the remote control unit 3L. On the other hand, the remote control unit 3R in the driver's seat side position, since the position outside the range of the angle theta _1, the information processing unit 5 can not receive the remote control transmission signal.

  Then, the remote control unit 3L at the position on the passenger seat side adds a right hand / left hand determination signal indicating whether the operated hand is the right hand or the left hand to the remote control transmission signal and transmits the information. When the mounted vehicle is traveling, the processing unit 5 accepts the operation signal added to the remote control transmission signal only when the right hand / left hand determination signal indicates that the hand is right hand.

Therefore, if the driver tries to operate within the range of the angle θ _{1 that} can be received by the information processing unit 5, that is, from the position of the remote control unit 3L, the driver has to operate using the left hand. In this case, the information processing unit 5 Discard the operation signal.

  As described above, the information processing unit 5 can input the operation signal added to the remote control transmission signal only when the right hand / left hand determination signal indicates the right hand, so that the operation signal generated by the driver's operation can be input. Can be discarded, and an operation signal by the operation of a passenger other than the driver can be input.

  As described above, according to the navigation device 1 to which the input device for an in-vehicle device according to the present embodiment is applied, an operation signal by an operation of a passenger other than the driver is accepted during traveling of the mounted vehicle regardless of the state of the driver. Therefore, a passenger other than the driver can operate the navigation device 1 without feeling bothered every time the operation is performed.

  In addition, although the input device of the vehicle-mounted device of the present embodiment has been described as an example applied to a navigation device, the input device of the vehicle-mounted device according to the present invention is applied to other vehicle-mounted devices such as a car audio in addition to the navigation device.
