Application of automobile power window controller for peripheral interface controller

In order to reduce the number of wires and the cost of automobile control system, Electronic controlling system of automobile power window is designed with the PIC18F258, integrated with CAN bus, as the core, hardware structure and flow chart of software were presented. Compared to the point-to-point control, the bus control not only reduces the wiring harness and cost, but also makes the control more flexible and fast. The experiment results show to be reliable performance and has the advantages of low-cost, low power and easy to maintain.
