Anti-lock brake control apparatus.

摘要

A brake control apparatus is described that prevents a wheel lockup condition by identifying the brake pressure that produces the maximum possible braking effort during each brake pressure application period and applying a predetermined fraction of the identified pressure after an incipient wheel lockup condition is sensed. One criteria for sensing an incipient wheel lockup condition is the decrease in the braking effort from the maximum possible braking effort by a predetermined amount as wheel slip increases from a critical wheel slip value.
