The invention relates to an accelerator controller, a vehicle safety protection system and method, and a vehicle. The accelerator controller comprises an MCU, a DAC digital-to-analog conversion moduleand a double-pole relay. The MCU is connected with an external controller through a CAN, a control end of the MCU is connected with the double-pole relay, a data end of the MCU is connected with thedouble-pole relay through the DAC digital-to-analog conversion module, an accelerator pedal is connected with the double-pole relay, and the double-pole relay is connected with vehicle-mounted accelerator control ECU. The MCU receives a mode switching control instruction and/or an accelerator cut-off instruction sent by an external controller; the double-pole relay is controlled according to the mode switching control instruction so that the input end of the vehicle-mounted accelerator control ECU is connected with the DAC analog-to-digital conversion module or the accelerator pedal; and therefore, an intelligent driving control mode or an accelerator pedal control mode is achieved, and control over the accelerator control ECU is cut off according to the accelerator cut-off instruction. Accelerator control can be cut off in time in an emergency state, and therefore the safety of a driver and a vehicle is protected.
本发明涉及一种油门控制器、车辆安全防护系统和方法以及车辆。油门控制器包括:MCU、DAC数模转换模块和双刀继电器;MCU通过CAN连接外部控制器,MCU的控制端连接所述双刀继电器,MCU的数据端通过DAC数模转换模块连接双刀继电器,油门踏板连接双刀继电器,双刀继电器连接车载油门控制ECU;MCU接收外部控制器发送的模式切换控制指令和/或油门切断指令;并根据模式切换控制指令控制双刀继电器使车载油门控制ECU输入端与DAC模数转换模块接通或者与油门踏板接通,以实现智能驾驶控制模式或者油门踏板控制模式,以及根据油门切断指令断开对油门控制ECU的控制,在紧急状态下可及时切断油门控制,从而保护驾驶员及车辆的安全。
