A vehicle control device includes an information acquirer that acquires information on driving conditions of a vehicle at least containing a steering angle and a vehicle speed, a distribution amount setter that sets a distribution amount of a brake force to each of multiple wheels provided in the vehicle based on the driving conditions of the vehicle; and a brake controller that performs brake control of each of the multiple wheels according to the distribution amount set by the distribution amount setter. When the vehicle speed is equal to or lower than a 22nd vehicle speed value within a low vehicle speed range, the distribution amount setter sets the distribution amount of a brake force to each of the multiple wheels including a specific wheel to a value which is smaller than a distribution amount when the vehicle speed exceeds the 22nd vehicle speed value.

A vehicle stop holding device for holding a stop of a vehicle includes a ECU for starting execution of a backup control for holding a stop state of the vehicle by a brake holding device when an operation of getting off the driver of the vehicle is detected while the vehicle is stopped by the brake device, and ECU outputs a brake operation request for requesting an operation of the brake device to the driver and releases the brake of the brake device when both a release operation of the seat belt by the driver of the vehicle and an opening operation which is an operation for opening the door are detected during a period from the start of the execution of the backup control until the completion of the completion.

The disclosure relates to a method for releasing an electro-hydraulic parking brake of a motor vehicle, wherein a vehicle status is determined, in dependence on the vehicle status, a pre-charging pressure demand is determined by a control device, in the event of a pre-charging pressure demand, a hydraulic pre-charging pressure is generated by a pressure generating unit, and in the event of a parking brake release demand, the pre-charging pressure is directed to the electro-hydraulic parking brake.

The present invention provides a vehicle control system, a vehicle control device, and a vehicle control method that are highly safe and prevent an own vehicle from suddenly starting during a two-stage stop. A vehicle control system 1 includes an external environment recognition unit 120 that recognizes external environment information that is information on the surroundings of the vehicle; a driver monitoring unit 130 that detects the direction of the line of sight of a driver of the vehicle; a brake holding unit 150 that maintains the state of operation of brakes of the vehicle; a brake holding control unit 144 that controls the turning ON or OFF of the brake holding unit 150; and a driver monitoring condition generation unit 143 that generates, on the basis of the external environment information detected by the external environment recognition unit, a line-of-sight condition of the driver's line of sight to be detected by the driver monitoring unit. The brake holding control unit 144 performs control to turn off the brake holding unit 150 in a case where the driver's line of sight detected by the driver monitoring unit 130 satisfies the line-of-sight condition.
