Abstract: In the present invention, a brake device is equipped with: differential pressure control valves; pressure adjusting units which are connected to the differential pressure control valves through liquid passages; and a control device which controls the WC pressure Pwc in wheel cylinders by operating the differential pressure control valves and the pressure adjusting units. When predetermined suppression control permission conditions are satisfied while both the supply pumps of the pressure adjusting units and the differential pressure control valves are in operation, the control device performs self-excited vibration suppression control over the differential pressure control valves, the self-excited vibration suppression control being carried out in such a manner that a valve element separated from a valve seat is caused to abut on the valve seat, and, upon abutting on the valve seat, the valve element is separated from the valve seat.

Abstract: A travel control device includes a first arithmetic unit configured to calculate a target moment, that is, a turning moment necessary for causing a vehicle to turn and move along a target path from a current position to a target position; a second arithmetic unit configured to calculate a limit moment, that is, a maximum turning moment which can be generated by a steering mechanism of the vehicle by the time the vehicle reaches the target position from the current position, while taking into account at least response delays of the vehicle; and an output unit configured to output brake commands for causing brake devices, which are respectively disposed so as to correspond to multiple wheels of the vehicle, to independently generate a braking force when the target moment is greater than the limit moment such that an insufficient moment corresponding to the difference between the target moment and the limit moment is generated.

Abstract: This vehicle control device is provided with: a control unit for executing one-pedal control, that is, the control for accelerating a vehicle when a single pedal is depressed from a predetermined reference point of a pedal stroke, and for decelerating the vehicle when the pedal is released from the reference point; and a determination unit for determining whether or not a rate of change in a pedal operation amount when the pedal is released is equal to or greater than a first threshold value. The control unit performs control for increasing a braking force when the rate of change is equal to or greater than the first threshold value.

Abstract: A vehicle brake controller is capable of executing limit control when a driver is performing a brake pedal operation during turning of a vehicle, to limit an increase in a braking force applied to an inner wheel that is a wheel positioned on the inner side of the turn. The vehicle brake controller is configured to start the limit control when a wheel state value that becomes greater as deceleration of the inner wheel becomes greater exceeds a start determination value that is set to a value greater than zero.
