The invention relates to the technical field of motor control, and discloses an automobile driving motor safety state control device and method, and the device comprises a power supply chip, a processor, a motor rotating speed obtaining module, a switch module, an ASC logic module, and a motor control module. One side of the switch module is connected with the power supply chip, the processor and the motor rotating speed acquisition module, and the other side of the switch module is connected with the ASC logic module; the ASC logic module is connected with the motor control module; the motor rotating speed acquisition module outputs a first control signal to the switch module based on the received first safety state control signal and/or the second safety state control signal in combination with a preset reference voltage; and the switch module determines a gating signal from the first safety state control signal, the second safety state control signal and the first control signal according to the first control signal and outputs the gating signal to the ASC logic module, so that the ASC logic module performs corresponding safety state control on the motor control module according to the gating signal, the development cost can be remarkably reduced, and the control efficiency is improved.

    本发明涉及电机控制技术领域,公开了一种汽车驱动电机安全状态控制装置及控制方法,装置包括:电源芯片、处理器、电机转速获取模块、开关模块、ASC逻辑模块和电机控制模块;开关模块的一侧分别连电源芯片、处理器和电机转速获取模块,另一侧连ASC逻辑模块;ASC逻辑模块连接电机控制模块;电机转速获取模块基于接收到的第一安全状态控制信号和/或第二安全状态控制信号并结合预设参考电压向开关模块输出第一控制信号;开关模块根据第一控制信号在第一安全状态控制信号、第二安全状态控制信号及第一控制信号中确定选通信号输出至ASC逻辑模块以使其根据选通信号对电机控制模块进行相应安全状态控制,可显著降低开发成本,提高控制效率。
