Vehicle Brake Apparatus and Method

摘要

A vehicle brake apparatus has a wheel cylinder that generates a braking force when a pump (5) is rotated in a first direction and does not generate the braking force when the pump (5) is rotated in a second direction. A brake control section (15) operates a valve (6) to open a channel between the pump (5) and the wheel cylinder (3) and rotates the pump (5) in the first direction to increase the braking force in accordance with a driver braking operation (1). The brake control section (15) operates the valve (6) to close the channel between the pump (5) and the wheel cylinder (3) to maintain the braking force in accordance with the driver braking operation (1). The brake control section (15) rotates the pump (5) in the second direction when the driver braking operation (1) is not performed. The diagnosis section detects a rotation state of the pump (5) while the pump (5) rotates in the second direction to diagnose abnormalities in the pump (5).
