Abstract:
1. A brake controller, comprising: an accelerator opening degree detecting means for detecting a pressing amount of an accelerator pedal; an input piston that is moved in accordance with a movement of a brake pedal; an assist piston that is moved by an electric motor; a master cylinder for generating therein a pressure of brake fluid in accordance with movements of the input piston and the assist piston; a slope climbing vehicle stopping detecting means for determining whether a vehicle has stopped while climbing a slope; a controller for controlling the electric motor; and a pedal release detecting means for detecting a release of the brake pedal; wherein when i) the slope climbing vehicle stopping detecting means determines that the vehicle has stopped while climbing a slope, and ii) the pedal release detecting means detects that the brake pedal is released, the controller controls the electric motor to move the assist piston so that an amount of a pressure decrease of the brake fluid caused by movement of the input piston during a release movement of the brake pedal is compensated by a movement of the assist piston to overcome said pressure decrease of brake fluid in the master cylinder.
