Abstract

An anti-lock braking system provides for the initial disconnection of the vehicle wiring connected to the wheel speed sensors. A wheel speed simulator then provides a signal simulating the rotation of the vehicle wheels. the wheel circuits are then sequentially tested by applying brake pressure to the wheel circuit and inserting into the wheel circuit, a resistor simulating a locked wheel. The brake pressur decay and rise can then be checked against the required value.
