On the contactless combined switch system for vehicle

We develop a kind of late-model contactless combined switch for vehicle base on Hall IC. The switching signal is triggered by magnetic filed. The MCU of master node is embedded RTOS. We make use of CAN bus system for the transmission of control signal. In this article, the hardware structure and software development of the new automobile combined switch system is discussed in detail. By testing, all functions of this system are realized and the control effect is good.
