The invention relates to a motor control device, which comprises a plurality of control units at least comprising a first control unit and a second control unit, and further comprises an ignition switch of which one end is connected with a first power supply and the other end is connected to a first ignition voltage detection end of the first control unit, the first control unit judges that the ignition switch is switched on when the voltage of the first ignition voltage detection end is greater than a first specified value; the insulation unit is provided with a first input end and a second input end; the first input end is connected with the other end of the ignition switch; the second input end is connected with a second power supply; the output end is connected to a second ignition voltage detection end of the second control unit, when the voltage of the first input end is larger than or equal to a preset threshold value, the voltage of the second input end is output, and when the voltage of the second ignition voltage detection end is larger than a second specified value, the second control unit judges that the ignition switch is switched on; the first input end is electrically insulated from the second input end and the output end.

    本发明涉及一种电动机控制装置,包括至少包含第一控制单元和第二控制单元的多个控制单元,还包括:一端与第一电源相连接,另一端连接至第一控制单元的第一点火电压检测端的点火开关,第一控制单元在第一点火电压检测端的电压为第一规定值以上时判断所述点火开关导通;以及绝缘单元,该绝缘单元具有:与所述点火开关的另一端相连接的第一输入端;与第二电源相连接的第二输入端;以及输出端,该输出端连接至第二控制单元的第二点火电压检测端,在第一输入端的电压大于或等于预先设定的阈值时,输出第二输入端的电压,第二控制单元在第二点火电压检测端的电压为第二规定值以上时判断点火开关导通,第一输入端与第二输入端、输出端电绝缘。
