The invention discloses a rear-end collision reminding mode system, which comprises a vehicle body domain controller BDM, a brake lamp, a brake lamp control module, a CAN network module and an LIN network main node module, and is characterized in that the vehicle body domain controller BDM is used for acquiring a braking force signal or a brake pedal travel signal of a current vehicle from the CAN network module; and then a LIN signal is used for driving the brake lamp control module to control the brake lamp to flicker. According to the system, the flicker frequency of the brake lamp can be controlled through the LIN network main node module by means of the LIN signal, the flicker frequency of the brake lamp is controlled to be 3-5 Hz, on the premise that the GB4785-2019 standard is met, the brake deceleration of a front vehicle can be expressed by means of different flicker frequencies of the brake lamp, the mode of expressing the magnitude of the brake force is clear, the traction braking deceleration can be obviously provided, the whole system is stable and reliable, signal transmission is accurate, and misjudgment is avoided.
本发明公开了一种后车追尾提醒模式系统,包括车身域控制器BDM、制动灯、制动灯控制模块、CAN网络模块和LIN网络主节点模块,所述车身域控制器BDM用于从CAN网络模块获取当前车辆的制动力信号或制动踏板行程信号,然后利用LIN信号驱动制动灯控制模块控制制动灯闪烁;本发明系统可以通过LIN网络主节点模块利用LIN信号控制制动灯的闪烁频率,并通过将制动灯的闪烁频率控制为3Hz‑5Hz,在满足GB4785‑2019标准的前提下,能够利用制动灯不同的闪烁频率来表达前车制动减速度,表达制动力大小方式明确,明显可以提供牵扯制动减速度大小,整个系统稳定可靠,信号传输准确,不会产生误判。
