Patent ES-451476-A1 (ES)
Title: Time delayed actuation of wheel slip control system for automotive vehicles and the like
IPC: B60T8/70
Filed: 1976-09-11
Abstract: A delay circuit in a wheel-slip control system prevents spurious triggering of the wheel slip control system due to false signals originating in misalignment, dirt or damage in wheel speed sensors. A time-delay circuit requires completion of a first cycle of wheel slip control system actuation, wherein both deceleration and velocity criteria must both be met, before deceleration signals alone are allowed to actuate the wheel slip control circuits. A timer enables subsequent cycles of actuation of the wheel slip control system by acceleration alone during a normal sequence of actuations within one brake application.
