Abstract:
1. A brake control apparatus for a vehicle configured to detect an amount of brake-pedal operation by means of an electric signal, then to calculate a braking force demanded by a driver from the electric signal, and thereby to generate the demanded braking force, wherein a control mode according to which a braking force is generated by the brake control apparatus 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 first command value for a stationary-vehicle braking force to be generated while the vehicle is in the stationary state, the control mode according to which the braking force is generated by the brake control apparatus is switched from the stationary-vehicle control mode to the normal control mode, if it is determined that the demanded braking force calculated from the amount of the driver's brake-pedal operation becomes smaller than a second command value for the stationary-vehicle braking force, in the stationary-vehicle control mode, a braking force generated by a means for braking is equal to a single set value for the stationary-vehicle braking force, while in the normal control mode, the braking force generated by the means for braking is equal to the demanded braking force, in the stationary-vehicle control mode, a limit is imposed on a motor driving current of the brake control apparatus, the normal control mode is switched to the stationary-vehicle control mode in a gradual manner, the determination that the vehicle is in the stationary state is made if the vehicle remains in the stationary state for a predetermined length of time, and the first command value and the second command value are the single set value.
