Patent ID: 8818671

Claim:
A vehicle brake controller comprising: a master cylinder that generates a master cylinder pressure corresponding to a brake operation; a wheel cylinder arranged at a front or rear wheel to provide a hydraulic brake force corresponding to a wheel cylinder pressure to a corresponding one of the wheels; a brake hydraulic actuator installed between the master cylinder and the wheel cylinders, the brake hydraulic actuator including a hydraulic pump driven by a pump motor, and a differential pressure valve that controls a differential pressure between the wheel cylinder pressure and the master cylinder pressure; a vehicle-stop-state motor-OFF controller configured to perform a vehicle-stop-state motor-OFF control that stops the pump motor upon the vehicle being stopped by the brake operation, and that maintains a stop state of the pump motor as is during stopping of the vehicle; and a pressurization rate controller configured to adjust a pressurization rate of the wheel cylinder pressure to a higher value as a road surface gradient becomes larger, upon resuming operation of the pump motor after the vehicle-stop-state motor-OFF control ends due to acceleration from the vehicle stop state.
