Abstract
An anti-lock braking system (ABS) for multi-axle vehicles equipped with multiple wheel-speed sensors and modulators for adjustment of braking pressure. The brake cylinder for each wheel may be controlled by an individual modulator, or, alternatively, a single common supply axle modulator may regulate both brake cylinders of an axle. In a preferred embodiment, the ABS is controlled by an ABS electronic control unit (ECU), which has four regulating channels with four corresponding end stages for controlling three modulators, where one of the modulators is commonly regulated by two end stages. The ECU also detects whether it is coupled to a proper ABS. The ABS electronic control unit eliminates the danger of an undetected installation of an ABS electronic control unit into an incompatible anti-lock braking system.
