Abstract
A process is disclosed for use in a micro-processor managed brake control system that utilizes wheel speed sensors and a brake off/on switch when the system requires information as to whether the vehicle is experiencing hard braking. In accordance with the process, the average deceleration of the undriven wheels is estimated and the slip of each undriven wheel is estimated and the results are compared with predetermined values for these parameters over a suitable test period. At the conclusion of these tests, the data may be used in place of data from a brake pedal position sensor or to confirm the data from such a sensor.
