The invention relates to the technical field of electric vehicles, in particular to an electric vehicle brake lamp lightening control system which comprises an MCU, a power source, a brake switch, a bus and a brake lamp. An input signal of the brake lamp is connected with the MCU through a bus; the MCU is connected with the brake switch through a bus; in the braking process of the electric vehicle, a braking signal sent through the bus is received, and the MCU lights up the braking lamp according to the signal duration; and in the vehicle energy recovery process, the MCU lights up the brake lamp according to the energy recovery state duration. The lightening function is executed through the MCU, and the brake lamp can be lightened no matter in the normal braking process or the energy recovery process; according to the invention, centralized control of lighting of the brake lamp of the electric vehicle can be realized, the life and property safety of road users is improved, the hidden danger of safety accidents caused by the fact that the brake lamp is not lighted in a sliding energy recovery state is completely eradicated, and the control is flexible, safe and reliable.
本发明涉及电动车辆技术领域,特别是涉及一种电动车辆制动灯点亮控制系统,其包括MCU、电源、制动开关和总线,还包括制动灯;制动灯的输入信号通过总线连接MCU;MCU和制动开关之间通过总线连接;电动车辆制动过程中,接收到通过总线发送的制动信号,MCU跟随信号时长点亮制动灯;车辆能量回收过程中,MCU根据能量回收状态时长点亮制动灯。本发明通过MCU执行点亮功能,无论是正常制动还是能量回收过程均可点亮制动灯;本发明可以实现电动车辆制动灯点亮的集中控制,并且提高道路使用者的生命财产安全,杜绝了因滑行能量回收状态下未点亮制动灯而发生安全事故的隐患,并且控制灵活,安全可靠。
