The invention discloses an electric automobile low-speed alarm system. The low-speed alarm system comprises a circuit protection module, a power module, a main control module and an audio output module; the circuit protection module inputs a stable direct current power supply to the power supply module, and the power supply module is used for supplying power to the main control module and the audio output module; the main control module comprises an MCU circuit, a CAN circuit and a FLASH circuit; the MCU circuit is used for receiving vehicle routine and network communication messages and diagnosis communication messages, sending a low-speed alarm system state and diagnosis communication messages, detecting and diagnosing all dependencies of a low-speed warning tone system and controlling the audio output module; the CAN circuit is used for sending messages between the vehicle bus and the MCU circuit; and the FLASH circuit is mainly responsible for storing system and vehicle fault information. The low-speed alarm system of the electric automobile can intelligently prompt pedestrians outside the automobile, and traffic accidents caused by the fact that the pedestrians outside the automobile cannot be prompted due to small sound during starting are avoided.

    本发明公开了一种电动汽车低速报警系统,包括电路保护模块、电源模块、主控模块和音频输出模块;所述电路保护模块为电源模块输入稳定的直流电源,所述电源模块用于为主控模块和音频输出模块供电;所述主控模块包括MCU电路、CAN电路和FLASH电路;所述MCU电路用于接收车辆常规及网络通信报文和诊断通信报文、发送低速报警系统状态及诊断通信报文、检测及诊断低速提示音系统所有依赖项、控制所述音频输出模块;所述CAN电路用于车辆总线与MCU电路的报文发送;所述FLASH电路主要负责保存系统及车辆故障信息。本发明的电动汽车低速报警系统可以智能为车外行人提示音,避免由于起步时声音较小不能给车外行人提示容易发生交通事故。
