摘要
为了减少汽车控制系统线束和降低成本,提出了以集成CAN控制器的PIC18F258单片机为核心,设计而成的汽车电动车窗控制系统,给出了系统主要硬件结构和软件设计流程并通过对时间和采样电流的处理,判断车窗是否遇到障碍物,从而实现车窗的防夹功能。相对于传统的点对点控制方式,不仅减少了车内的线束、降低成本,而且控制灵活、实时性强。试验表明,该系统工作正常、性能可靠,具有低成本、低功耗和易于维修等优点。
Aimed at the demand of reducing the wiring harness and declining cost in the automobile control system, electrical controlling system of automobile power window is designed with PIC18F258 single chip computer of integrated CAN bus as the core. Hardware structure and flow chart of software are presented. Through the processing of time and sample current,it can be judged whether the automobile window meets a barrier, thus realizing the anti-pinch function of window. 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 this system can operate normally, the advantage of this system are reliable performance,low cost,low power consumption and easy to maintain.
