  • Control apparatus for maintaining braking force
    Patent number: 4864504
    Abstract: A control apparatus is provided for maintaining a braking force in an automotive vehicle for calculating the rate at which vehicle velocity decreases when braking is applied, and for inhibiting braking force maintenance control within a predetermined period of time after brake release when the rate of velocity decrease exceeds a predetermined value. The braking force maintaining function is prevented from operating erroneously by distinguishing between a state in which the vehicle is at rest and a state in which the vehicle wheels are locked up.
