Abstract： In order to solve the complex wiring and low reliability of conventional light control system， an automobile contactless switch light system is designed combined with Hall element and controller area network (CAN) bus technology. The processing system of electromagnetic compatibility controlled by CAN bus is improved to reduce the electromagnetic interference from the controller and other sources of interference. With Freescale's high-performance single-chip MC9S08DZ60 and CAN transceiver TJA1050, the overall circuit design and software design are presented. The test results show that the designed light control system is feasible.
