Abstract

A two-wire connecting system for linking an Electronic Parking Brake and Wheel Speed Sensor to a vehicle control module utilizing a ternary analogous signal. One or more diodes are implemented in the connecting system to selectively power the Electronic Parking Brake and Wheel Speed Sensor. By halving the number of wires, the connecting system is lighter than traditional 4-wire connecting systems that link an Electronic Parking Brake and Wheel Speed Sensor with a control module.
