    摘要: A method and system, for use with a vehicle including a pair of front wheels, a pair of rear wheels, and an anti-lock brake system (ABS), for detecting when the vehicle is executing a turning maneuver. The system includes means for performing the method steps of determining a speed difference between one pair of the vehicle wheels, determining the deceleration of each of the one pair of vehicle wheels, comparing the speed difference to a turning detection threshold, comparing the decelerations to a deceleration threshold, and detecting a turning maneuver based on those comparisons.

    摘要: A control method and system for a vehicle anti-lock brake system to provide for recovery from premature activation of the vehicle anti-lock brake system. The control system includes a microprocessor and accompanying components to perform the control method steps of generating an input signal representing a vehicle wheel velocity, processing the input signal to determine a wheel slip duration, comparing the wheel slip duration to a slip duration threshold, generating a premature activation recovery control signal when the wheel slip duration fails to exceed the slip duration threshold, and performing premature activation recovery control of the anti-lock brake system in response to the premature activation recovery control signal.

    摘要: A brake pressure controller, responsive to a wheel speed sensor and coupled to a brake, performs a cyclic control of pressure applied to the brake. A brake pressure cycle includes a pressure apply stage and a pressure dump stage having activation conditions based upon a slip threshold parameter. A predetermined base threshold quantity is modified in dependence upon a measured time duration of the pressure dump stage and/or a slip depth error quantity so that a greater amount of slip is added to the base slip threshold when braking on a deformable surface than when braking on a non-deformable surface.
