Abstract:
1. A vehicular brake control apparatus comprising: a braked member that rotates together with a wheel; a braking member that produces a braking torque when pressed against the braked member; an electric driving device that presses the braking member against the braked member by driving in a predetermined direction so as to apply a braking torque to the wheel when being supplied with electric current; an operational state detector that detects an operational state of the vehicle which includes a quantity of brake operation, and provides a quantity of state representative of the operational state of the vehicle; a braking torque change request determiner that selectively determines that the braking torque is to be increased and that the braking torque is to be reduced, based on the quantity of brake operation; and a current controller that controls the supply of electrical current to the electric driving device so that the electric driving device is caused to drive in a predetermined direction if it is determined that the braking torque is to be increased, wherein the current controller controls the supply of electrical current to the electric driving device so that the supply of electrical current is discontinued if it is determined that the braking torque is to be reduced based on the quantity of brake operation by a driver, and controls the supply of the electric current to the electric driving device so that the electric driving device is rotated in a direction opposite to the predetermined direction if it is determined that the braking torque is to be reduced based on the quantity of the operational state of the vehicle other than the quantity of brake operation.
