Abstract

A testing apparatus for an anti-lock control system for vehicle brakes for testing the correct functioning of the control system. In one embodiment, the apparatus establishes a predetermined speed and compares this predetermined speed to the speed sensed by the sensing portion of the control system. When the predetermined speed is exceeded by the moving vehicle a testing apparatus is triggered which initiates a test procedure for the control system. The apparatus includes a switching device to insure that a test procedure is initiated only after the vehicle ignition switch is actuated. In another embodiment, the apparatus employs a temperature sensor and/or the control system output for initiating a test procedure, but not during a deceleration of the vehicle. In a further variant, two threshold levels are established, each of which must be encountered before the test procedure is initiated.
