Abstract
A method of testing the performance of an anti-lock brake control system of the type wherein an electronic control circuit signals each modulator to increase, decrease, or hold the hydraulic fluid pressure on the corresponding wheel brake as required by the varying wheel speed. The method dictates the sequential delivery of quasi brake control signals from the control circuit to the respective modulators, each signal being capable of causing an increase, a decrease and a holding of the fluid pressure on one brake. The resulting braking forces being exerted on the respective vehicle wheels are measured as by a dynamometer connected to motored rollers under the vehicle wheels.
