ABSTRACT:
An anti-lock brake system for a tri-axle wheeled vehicle equipped with wheel speed sensors and modulators for adjusting brake pressure. The modulators are actuated by a six-channel electronic control unit. The modulators associated with the front axle of the vehicle are individually actuated. The modulators associated with the two rear axles of the vehicle are side-by-side or axle modulators, each actuated jointly by respective end stages of the six channels. The electronic control unit detects whether the anti-lock brake system in which it is installed is a compatible anti-lock brake system. An error signal indicating improper installation is delivered.
