The Electronic Control System of the Second-Generation CST Vehicle Collision Energy Absorption System

In order to develop the electronic control system of the second-generation CST vehicle collision energy absorption system, the drive motor will be installed aside, and the transmission gear drive style will be added to this system. Among the first-generation products, the drive motor was fixed on the bumper, due to the gravitation, the transmission torque of the flexible shock pole dramatically increased. From this the second-generation products not only solved this problem which existed in the previous products, but also reduced the difficulty of the electronic control system design. On this base, the drive motor was confirmed, and the design of the control circuit was divided into two modules, the main circuit module and the relay module. The main circuit module comprises regular power supply circuit, signal-input amply circuit, route switch circuit and signal-output relay drive circuit. In the main circuit, a SCM STC89C58RD was applied as the core to the control circuit, explored the corresponding control software, and got a successful application in ZOTYE2008, consequently afforded a new control module for the CST Vehicle Collision Energy Absorption System.
