Abstract
Provided is a brake control apparatus for a vehicle which detects an amount of brake-pedal operation by means of an electric signal, and then calculates a braking force demanded by a driver from the electric signal, and thereby generates the demanded braking force. A control mode for a braking force is switched from a normal control mode to a stationary-vehicle control mode, if a determination that the vehicle is in a stationary state is followed by another determination that an electric signal corresponding to an actual braking force exceeds a command value for a stationary-vehicle braking force while the vehicle is in the stationary state. The control mode for a braking force is switched from the stationary-vehicle control mode to the normal control mode, if it is determined that the demanded braking force becomes smaller than the command value for the stationary-vehicle braking force. In addition, in the stationary-vehicle control mode, a braking force generated by a means for braking is equal to the command value for the stationary-vehicle braking force, whereas, in the normal control mode, the braking force generated by the means for braking is equal to the braking force demanded by the driver.
