Abstract
A brake control apparatus is provided with a simulator for applying a biasing force to a manually operated braking member of a vehicle in response to braking operation. A sensor detects conditions of the vehicle including a braking condition of the vehicle. A first biasing device applies a first biasing force to the manually operated braking member in response to braking operation, and a second biasing device applies a second biasing force, as well. Only one of the first and second biasing devices applies the biasing force to the manually operated braking member when a predetermined condition is detected by the sensor, while both of the first and second biasing devices apply the biasing forces in the normal braking operation. The second biasing device may include a cylinder having a bore defined therein, and a piston slidably received in the bore to define a chamber filled with brake fluid, an elastic member for biasing the piston to expand the chamber, and a reservoir communicated with the chamber of the cylinder for storing the brake fluid drained from the cylinder, and controlled by a controller in response to outputs of the sensor.
