Title: VEHICLE CONTROL DEVICE
Abstract:
A vehicle control device 20 is provided with: a fluid pressure generator 21 having a servo pressure generator 70 for adjusting the MC pressure in a master chamber 36 that is connected with wheel cylinders 13a-13d, such that the WC pressure inside the wheel cylinders 13a-13d is increased by increasing the MC pressure; and a brake actuator 22 with which it is possible to separately adjust the WC pressure in the front wheel cylinders 13a, 13b and the rear wheel cylinders 13c, 13d. In a low braking requirement state, increase in the MC pressure due to the action of the servo pressure generator 70 is limited, and the WC pressure inside the front wheel cylinders 13a, 13b is adjusted by the action of the brake actuator 22. When not in a low braking requirement state, the MC pressure is adjusted by the action of the servo pressure generator 70, and the WC pressure in the wheel cylinders 13a-13d is adjusted.
