In the present embodiment, the function of controlling various in-vehicle devices in the control device 100 constitutes the device control unit 100 b.

  The control device 100 controls, for example, the indoor air conditioner 20 and the seat air conditioner 30 such that the temperature of the air blown into the vehicle compartment becomes the target temperature TAO. Note that the control device 100 sets the target temperature TAO based on, for example, the set temperature set by the temperature setting switch 110b, the detection value of the outside air temperature sensor 101, the detection value of the inside air temperature sensor 102, and the detection value of the solar radiation sensor 103.

  In the above-mentioned sleep condition, the automatic driving degree specified by the specifying unit 100a is level 4 (that is, the system dependent driving degree), and a request signal from the request output unit 100c is given to the device control unit 100b. It is a condition that holds in the case.

  Further, the control device 100 according to the present embodiment controls various in-vehicle devices such that the operation mode of the in-vehicle devices shifts from the sleep mode to the normal mode when a predetermined awakening condition is satisfied. The above-mentioned awakening condition is a condition that holds when a sign that the degree of automatic driving is switched from the system dependent driving degree to the driver dependent driving degree is detected while the operation mode of the in-vehicle device is the sleep mode. There is.

  For example, when the driver operates the steering wheel or the shift lever as the sign of switching to the driver dependent driving degree, when the vehicle traveling around has an unnatural motion such as rapid deceleration, etc. When traveling on a road, for example, when approaching near the exit on the guidance route. In the present embodiment, the function of detecting a sign of switching to the driver dependent driving degree in the control device 100 constitutes the sign detection unit 100d.

  Next, an example of control processing executed by the control device 100 of the present embodiment will be described with reference to the flowchart shown in FIG. In addition, as a condition where the following control is performed, the case where the sheet | seat air conditioning switch 110c is turned on at least is assumed. The processing illustrated in FIG. 7 is periodically executed by the control device 100.

  As shown in FIG. 7, in step S100, the control device 100 reads various signals from the automatic driving system 10, the various sensors 101 to 103, the navigation device 105, the operation panel 110, and the like.

  Then, control device 100 specifies the present degree of automatic driving based on the information acquired from automatic driving system 10 in Step S110. Specifically, control device 100 specifies whether the current degree of automatic driving is the level 4 system dependent driving degree or the level 0 to 3 driver dependent driving degree.

  Subsequently, at step S120, control device 100 determines whether or not the current degree of automatic driving is the system dependent driving degree. As a result, when the current degree of automatic driving is not the system dependent driving degree but the driver dependent driving degree, the control device 100 sets the operation mode of various in-vehicle devices to the awakening of the occupant in step S130. Migrate to When the normal mode is already set, the normal mode is continued.

  Specifically, in step S130, the control device 100 controls the seat air conditioner 30 such that the air conditioning mode becomes the normal air conditioning mode other than the sleep air conditioning mode. The control device 100 according to the present embodiment controls the seat air conditioner 30 such that the temperature of the air blown out from the surface of the seat 3 into the vehicle compartment approaches the set temperature set by the occupant. Specifically, the control device 100 controls the seat air conditioner 30 based on the set temperature, the detection value of the outside air temperature sensor 101, the detection value of the inside air temperature sensor 102, and the target temperature TAO calculated from the detection value of the solar radiation sensor 103. Do.

  Further, the control device 100 controls the seat adjustment device 40 so that the seat 3 is in the standing mode in the normal mode, and the light control device 50 in such a manner that the clear mode allows light incident into the vehicle compartment. Control.

  On the other hand, as a result of the determination processing in step S120, when the automatic driving degree is the system dependent driving degree, the control device 100 determines in step S140 whether the sleep switch 110d is turned on.

  As a result, when the sleep switch 110d is not turned on, in step S130, the control device 100 shifts the operation mode of various in-vehicle devices to the normal mode suitable for the awakening of the occupant. When the normal mode is already set, the normal mode is continued.

  On the other hand, when the sleep switch 110d is turned on, in step S150, the control device 100 shifts the operation mode of various in-vehicle devices to the sleep mode in which the function suitable for sleep is exhibited. If the sleep mode has already been entered, the sleep mode will be continued.

  Specifically, in step S150, the control device 100 controls the seat air conditioner 30 so that the air conditioning mode becomes the sleep air conditioning mode suitable for sleep. The control device 100 of the present embodiment controls the seat air conditioner 30 such that the temperature of the air blown out from the surface of the seat 3 into the vehicle cabin approaches the comfortable sleep temperature (for example, the set temperature + 1 ° C.) higher than the set temperature. Specifically, the control device 100 sets a temperature obtained by adding a predetermined temperature (for example, 1 ° C.) to the target temperature TAO as a target value, and controls the seat air conditioner 30 based on the target value.

  However, it is desirable for the driver not to be too warm at least in the vicinity of the head, since it is assumed that there is a sudden driving demand. That is, it is desirable for the control device 100 to control the seat air conditioner 30 so as to have a head-to-foot thermal type temperature distribution in the sleep mode.

  Further, the control device 100 controls the seat adjustment device 40 so that the reclining angle is larger in the sleep mode than in the normal mode. Specifically, the control device 100 controls the sheet adjustment device 40 so that the sheet 3 is in the flat mode in the sleep mode.

  Furthermore, the control device 100 controls the light control device 50 so as to be in a darkening mode in which the incidence of light into the vehicle compartment is blocked. Specifically, the control device 100 energizes the light control film to switch the windshield 5 or the like to a colored state such as black so that the light entering into the vehicle compartment is blocked.

  When the operation mode of various in-vehicle devices shifts to the sleep mode by the control of the control device 100, as shown in FIGS. 8 and 9, the seat 3 becomes flat state suitable for sleep, and the seat 3 is suitable for sleep Air of temperature is blown out. At this time, since the vehicle interior is in a dark mode in which the light control device 50 blocks the light incidence, the environment is more suitable for sleep.

  Returning to FIG. 9, the control device 100 determines in step S160 whether or not there is a switch indication of the automatic driving degree. In other words, in step S160, the control device 100 determines whether a sign that the automatic driving degree switches to the driver dependent driving degree is detected. As described above, the control device 100 detects a switch indication to the driver-dependent driving degree based on a predetermined operation by the driver, the situation of surrounding vehicles, the traveling state of the own vehicle, and the like.

  If there is no switch indication of the automatic driving degree as a result of the determination processing in step S160, the control device 100 continues the sleep mode, and shifts to the normal mode in step S130 if there is the switch sign of the automatic driving degree. .

  The control device 100 according to the present embodiment is configured to control various in-vehicle devices such that the transition from the sleep mode to the normal mode is completed before the switching of the automatic driving degree to the driver dependency is completed. There is. However, it is desirable that the control device 100 be configured to control the operation of various in-vehicle devices to gradually become the normal operation so as not to give discomfort to the occupant.

  The control device 100 according to the present embodiment described above has the operation mode of the in-vehicle device suitable for sleep when there is a request signal for requesting transition to the sleep mode when the automatic operation degree becomes the system dependent operation degree. It is configured to shift to the sleep mode. According to this, the occupant can be guided to a comfortable sleep state without a sense of discomfort.

  In addition, when the automatic driving degree is the driver dependent driving degree, the control device 100 according to the present embodiment does not make the operation mode to be the sleep mode regardless of the presence or absence of the request signal for requesting the transition to the sleep mode. Control the in-vehicle devices. According to this, the safety of the autonomous driving vehicle 1 can be secured.

  Furthermore, the control device 100 according to the present embodiment changes the operation mode from the sleep mode to the normal mode suitable for the awakening of the occupant at a stage before the automatic driving degree switches from the system dependent driving degree to the driver dependent driving degree. It is configured to control in-vehicle devices. According to this, when switching from the system dependent driving degree to the driver dependent driving, the occupant can be awakened, so that the safety of the autonomous driving vehicle 1 can be secured.

  The control device 100 according to the present embodiment is configured to operate the seat air conditioner 30 in the sleep air conditioning mode during the sleep mode. According to this, the interior of the vehicle can be made an environment suitable for sleep. In particular, since the air conditioning by the seat air conditioner 30 becomes an individual air conditioning in each seat 3 and there is no need to air-condition the whole vehicle interior, it can be expected to lead to fuel saving.

  Further, the control device 100 of the present embodiment is configured to operate the seat adjustment device 40 in the flat mode during the sleep mode. According to this, it is possible to make the room an environment suitable for sleep. In the flat mode, even if the purpose is not sleeping, it is also possible to enjoy reading while moving with the occupant lying down.

  In particular, since the seat adjustment device 40 of the present embodiment includes the plurality of side covers 41 to 44, rolling of the occupant in the sleep mode can be prevented. Furthermore, by providing the plurality of side covers 41 to 44, it is possible to suppress the spread of heat, so that the surrounding environment of the occupant can be maintained at a comfortable temperature without bedding such as a futon or blanket. .

  Further, the control device 100 of the present embodiment is configured to operate the light control device 50 in the darkening mode at the time of the sleep mode. According to this, it is possible to prevent the sleep of the occupant from being disturbed by the light entering the vehicle compartment.

(Modification of the first embodiment)
In the first embodiment described above, an example has been described in which the seat air conditioner 30 is controlled so that the temperature of the air blown out from the surface of the seat 3 into the vehicle cabin approaches the pleasant sleep temperature higher than the set temperature during sleep air conditioning mode. It is not limited to this.

  It is not preferable because the conditioned air flow will be bothersome if the conditioned air quantity of a fixed quantity of air strikes the occupant's body for a long time, causing an increase in the discomfort of the occupant. For this reason, in the sleep air conditioning mode, for example, it is desirable to perform a swing operation in which the blowing direction of the conditioned air is periodically changed in the vertical and horizontal directions. In the sleep air conditioning mode, for example, it is desirable to perform a fluctuation operation in which the blowing speed of the conditioned air is periodically changed.

  Here, the feet of the occupant are less likely to move as compared to the upper body of the occupant, and in the sleep air conditioning mode, there is a high possibility that the feet of the occupant may continue to be hit for a long time. Therefore, for example, when the temperature of the air blown out toward the feet of the occupant becomes equal to or higher than a predetermined reference temperature (for example, 40 ° C.), the conditioned air is distributed to the upper body side of the occupant and blown out to the feet of the occupant. It is desirable to reduce the air flow.

Second Embodiment
Next, a second embodiment will be described with reference to FIG. 10 and FIG. The present embodiment is different from the first embodiment in that the request output unit 100c of the control device 100 is configured to output a request signal to the device control unit 100b when drowsiness of an occupant is detected. ing. In the present embodiment, the operation panel 110 is not provided with the sleep switch 110d.

  As shown in FIG. 10, a driver status monitor (DSM) 60 that functions as a drowsiness detection unit that detects drowsiness of a driver is connected to the control device 100 of the present embodiment. The driver status monitor 60 is configured to include an infrared camera and an image processing device.

  The driver status monitor 60 detects drowsiness of the driver by analyzing the direction of the face of the driver, the degree of opening of the eyes, and the like based on the image of the driver captured by the camera. The driver status monitor 60 determines, for example, whether or not the state in which the eyes are closed or not facing forward is continued for a predetermined time, and if the above-described state is continued for a predetermined time, etc. It shall be detected.

  The request output unit 100c of the control device 100 of the present embodiment outputs a request signal for requesting the device control unit 100b to shift to the sleep mode when the driver status monitor 60 detects drowsiness of the driver. It is a structure.

  Specifically, the control device 100 according to the present embodiment executes the process shown in FIG. 11 instead of the process shown in FIG. Note that among the steps shown in FIG. 11, steps given the same reference numerals as the steps shown in FIG. 7 execute the same processing unless otherwise stated.

  As shown in FIG. 11, when the automatic driving degree is the system dependent driving degree as a result of the determination processing in step S120, the controller 100 determines whether the driver's drowsiness is detected by the driver status monitor 60 in step S140A. It is determined whether or not.

  As a result, when drowsiness of the driver is not detected, the control device 100 shifts the operation mode of various in-vehicle devices to the normal mode suitable for the awakening of the occupant in step S130. When the normal mode is already set, the normal mode is continued.

  On the other hand, when drowsiness of the driver is detected, in step S150, the control device 100 shifts the operation mode of various in-vehicle devices to the sleep mode in which the function suitable for sleep is exhibited. If the sleep mode has already been entered, the sleep mode will be continued.

  Other configurations and operations are similar to those of the first embodiment. According to the control device 100 of the present embodiment, the same advantages as those of the first embodiment can be obtained from the same configuration and function as those of the first embodiment.

  In particular, in the present embodiment, the request output unit 100 c of the control device 100 outputs a request signal to the device control unit 100 b when drowsiness of the occupant is detected. According to this, since the transition to the sleep mode is requested in a state where the occupant's awareness becomes unclear due to sleepiness, the occupant does not feel discomfort when the operation mode of the in-vehicle device transitions to the sleep mode Can be

  Here, in the present embodiment, the driver status monitor 60 is exemplified as the drowsiness detection unit for detecting drowsiness of the driver, but the present invention is not limited to this. The drowsiness detection unit may adopt, for example, a device that detects sleepiness of the occupant based on biological information such as the heartbeat and pulse of the occupant. Further, it is desirable that the drowsiness detection unit be configured to detect drowsiness of the occupant other than the driver.
