汽车车身控制模块电路设计

Design of Vehicle Body Control Module Circuit

为了提高经济型轿车车身控制系统的集成度,获得更好的汽车驾驶性能,介绍了一款新开发的车身控制模块,以Freescale公司生产的16位高性能单片机MC9S12XDP512为主芯片,通过对电源管理模块、输入输出接口电路、RKE接收模块、CAN总线及LIN总线通信模块的合理设计,实现对汽车门锁及灯光等的智能控制。该设计完成了车身控制模块的硬件电路模型,为今后车身控制模块的设计提供参考。

To improve the integration of body control system for economic car and have a better driving performance, a new model body control module is developed. The 16 bit high performance mierocontroller MC9sl2xdpS12 made by Freescale as main chip, according to the reasonable design of power management module, input and output interface circuit, RKE receiver module and CAN bus and LIN bus communication module, to achieve the car locks and lighting intelligent control. The design of hardware circuit model is completed for the vehicle body control module, which provides a technical basis for the design of future vehicle body control module.
