The invention relates to an emergency operation device for an electronic parking actuator. The emergency operation device comprises a direct-current power supply, a starting key, a processor, a voltage converter, a three-phase power driving module, a three-phase inverter bridge and a wire harness plug. The direct-current power supply supplies power to the processor; the processor generates a three-phase driving waveform according to a target parking control parameter matched with the motor to be operated and determined from parking control parameters of a plurality of pre-stored motor models in response to a triggering action for the start key; the voltage converter is used for converting a direct-current voltage provided by the direct-current power supply into a driving voltage matched with the motor to be operated according to the instruction of the processor; the three-phase power driving module amplifies the three-phase driving waveform to obtain an amplified signal under the power supply of the driving voltage; the three-phase inverter bridge is connected with the to-be-operated motor through the wire harness plug and is driven by the amplification signal to invert the direct-current voltage into the alternating-current voltage so as to drive the to-be-operated motor to rotate, releasing or hanging of the electronic parking actuator is achieved, and driving safety is improved.

    本申请涉及一种电子驻车执行器应急操作装置,包括直流电源、启动按键、处理器、电压变换器、三相功率驱动模块、三相逆变桥和线束插头。直流电源向处理器供电;处理器响应于针对启动按键的触发动作,根据从预存储的若干个电机型号的驻车控制参数中确定的匹配于待操作电机的目标驻车控制参数,生成三相驱动波形;电压变换器根据处理器的指示,将直流电源提供的直流电压转换为匹配于待操作电机的驱动电压;三相功率驱动模块在驱动电压供电下,放大三相驱动波形得到放大信号;三相逆变桥通过线束插头与待操作电机连接,在放大信号驱动下,将直流电压逆变为交流电压,以驱动待操作电机旋转,实现电子驻车执行器的解除或挂入,提高了行车安全性。
