Study on CAN Communication of EBS and Braking Performance Test for Commercial Vehicle

EBS (electronic brake system) can effectively control and adjust braking force acting on every wheel, reduce braking response time and braking distance, and make vehicle achieve much more braking stability. It is featured with CAN (Controller Area Network) communication by which the sensor signals and control command signals can be transmitted and received. In the braking performance test of EBS, conventional test methods have some inconvenience in existence. For example, the fixing of pressure sensors and wheel speed sensors is restrained by the installation position, and the precision of measuring is prone to be affected by the environment conditions. But based on CAN communication technology, the special testing instrument can be connected with CAN bus, monitoring and recording signals on the bus. Thus signals representing braking performance can be acquired through CAN bus.
