ABSTRACT:
In a brake controller, a slope climbing vehicle stop detecting means determines when the vehicle is stopped while climbing a slope, and a pedal release detecting means determines that the pedal is released. An assist control unit interpolates a decrement in brake fluid pressure in the master cylinder due to an input piston movement caused by a release of a brake pedal. An assist piston is controlled by an electric motor to restore and maintain the fluid pressure within the master cylinder.
