CN-121989983-A - Control device for vehicle

Abstract

The invention aims to restrain the setting from being changed for a plurality of times according to the sleeping state when the setting of a vehicle is changed according to the sleeping state of a co-passenger of the vehicle. The processor of the ECU is provided with a sleep state determination unit that determines the sleep state of a passenger other than the driver, and a setting change unit that changes the setting of the driving assistance function of at least a part of the driving operation performed autonomously by the vehicle or the setting of the warning output from the HMI device, based on the sleep state of the passenger, wherein the setting change unit maintains the setting changed until the power of the vehicle is turned off after the setting is changed.

Claims (5)

1. 1. A control device for a vehicle is characterized by comprising: A sleep state determination unit for determining the sleep state of a passenger other than the driver, and A setting changing unit that changes a setting of a driving support function of at least a part of a driving operation performed autonomously by the vehicle or a setting of a warning output from a warning device based on a sleep state of the fellow passenger, The setting changing unit maintains the setting changed until the power of the vehicle is turned off after changing the setting.
2. 2. The control device for a vehicle according to claim 1, wherein, The setting changing unit changes the setting of the driving assistance function between a 1 st mode of a driving operation autonomously performed by the vehicle and a 2 nd mode of a driving operation slower than the 1 st mode in a normal state, and changes the setting of the driving assistance function from the 1 st mode to the 2 nd mode when it is determined that the fellow passenger is sleeping.
3. 3. The control device for a vehicle according to claim 1 or 2, characterized in that, When it is determined that the fellow passenger is sleeping, the setting changing unit further reduces the vehicle acceleration/deceleration based on the distance between the vehicle and the preceding vehicle or the steering amount based on the lane departure of the driving support function.
4. 4. The control device for a vehicle according to claim 1 or 2, characterized in that, When it is determined that the co-passenger is sleeping, the setting changing unit changes the timing of the steering intervention at the time of lane departure by the driving support function to an earlier timing.
5. 5. The control device for a vehicle according to claim 1 or 2, characterized in that, When it is determined that the co-passenger is sleeping, the setting changing unit decreases the volume of the warning output from the warning device.

Description

Control device for vehicle Technical Field The present invention relates to a control device for a vehicle. Background Conventionally, it is known to determine an acceleration/deceleration value based on a psychological state of a passenger group including a driver and a passenger at the time of automatic driving, and to correct a numerical value based on whether or not each passenger is sleeping when digitizing the psychological state (for example, refer to patent document 1). Patent document 1 Japanese patent application laid-open No. 2018-052160 Disclosure of Invention However, the sleep state of the occupant sometimes changes from moment to moment, and the sleep sometimes becomes deep or shallow. In the technique described in the above patent document, since the acceleration/deceleration value is changed a plurality of times according to the sleep state of the occupant, the driver may misunderstand the setting state of the acceleration/deceleration value of the driving assistance function. Further, if the driver erroneously recognizes the setting state of the driving support function, the driver excessively believes the driving support function, which affects the driving operation of the driver. Accordingly, an object of the present invention is to provide a vehicle control device capable of suppressing a plurality of changes in settings according to a sleep state when the settings of a vehicle are changed according to the sleep state of a passenger of the vehicle. The gist of the present invention is as follows: (1) A control device for a vehicle is provided with: A sleep state determination unit for determining the sleep state of a passenger other than the driver, and A setting changing unit that changes a setting of a driving support function of at least a part of a driving operation performed autonomously by the vehicle or a setting of a warning output from a warning device based on a sleep state of the fellow passenger, The setting changing unit maintains the setting changed until the power of the vehicle is turned off after changing the setting. (2) The control device for a vehicle according to the above (1), wherein, The setting changing unit changes the setting of the driving assistance function between a 1 st mode of a driving operation autonomously performed by the vehicle and a 2 nd mode of a driving operation slower than the 1 st mode in a normal state, and changes the setting of the driving assistance function from the 1 st mode to the 2 nd mode when it is determined that the fellow passenger is sleeping. (3) The control device for a vehicle according to the above (1) or (2), wherein, When it is determined that the fellow passenger is sleeping, the setting changing unit further reduces the vehicle acceleration/deceleration based on the distance between the vehicle and the preceding vehicle or the steering amount based on the lane departure of the driving support function. (4) The control device for a vehicle according to the above (1) or (2), wherein, When it is determined that the co-passenger is sleeping, the setting changing unit changes the timing of the steering intervention at the time of lane departure by the driving support function to an earlier timing. (5) The control device for a vehicle according to the above (1) or (2), wherein, When it is determined that the co-passenger is sleeping, the setting changing unit decreases the volume of the warning output from the warning device. Effects of the invention According to the present invention, there is provided a control device for a vehicle capable of suppressing a plurality of changes in settings according to a sleep state when the settings of the vehicle are changed according to the sleep state of a fellow passenger of the vehicle.
