The invention discloses a vehicle body control module awakening method. The method comprises the steps that a PTS is fixed to a brake pedal; after the IBC and the BCM enter the dormant state, the MCU is awakened periodically, the displacement stroke of the current pedal is checked through the PTS, and the MCU dormant time is determined according to the MCU awakening time, the MCU working current, the MCU static current and the MCU comprehensive static current; if the position of the current brake pedal travel is within the range of the brake lamp switch turn-on threshold value, a brake lamp switch turn-on current signal is sent out, and an IBC and a BCM are awakened; the brake system is simple in structure, the whole brake system is lighter, the development trend of the brake system towards high integration and light weight is met, and the production cost is greatly reduced.
本发明公开了一种车身控制模块唤醒方法,包括:将PTS固定在制动踏板上;在IBC和BCM进入休眠状态之后,MCU周期唤醒,通过PTS检查当前踏板的位移行程,MCU休眠时间根据MCU唤醒时间、MCU工作电流、MCU静态电流和MCU综合静态电流确定;若当前制动踏板行程的位置位于导通刹车灯开关阈值范围内,则发出刹车灯开关导通电流信号,并唤醒IBC和BCM;本发明结构简单,整个制动系统更加轻量化,符合制动系统向高度集成化与轻量化的发展趋势,且大大降低生产成本。
