Abstract

A process for load dependent braking regulations (ALB) utilizing components, signal paths and transmitters of an existing anti-lock braking system (ABS) to perform an automatically load-dependent braking function which takes effect well below the locking limit. The brake pressure and consequently the brake distribution are controlled by processing only wheel-speed differences as actual values of an electronic brake-pressure controller instead of absolute wheel slips. To compensate for changing load situations and roadway properties, the precontrollable brake-force distribution and the brake-pressure level control triggerable at the pedal are corrected in a self-learning and adaptive manner. The device for carrying out the ALB process consists essentially of a computer and software program using input from the ABS systems. The process according to the invention makes axle-load sensors superfluous.
