Motor control system and vehicle

A motor control system, comprising a main control unit, a power supply unit, and a driving unit, wherein

• the main control unit is configured to:
• obtain sampling data of a motor and a power supply signal from the driving unit, generate a motor control signal according to the sampling data, and output a safety enable signal when determining that motor drive is abnormal according to the sampling data or when determining that power supply to the driving unit is abnormal according to the power supply signal;
• the power supply unit is configured to:
• supply power to the main control unit, monitor a state of the main control unit, and output a safety cut-off signal when the power supply unit or the main control unit is abnormal;
• and
• the driving unit is configured to:
• drive the motor according to the motor control signal, and switch to a safe path when receiving any one of the safety enable signal or the safety cut-off signal;
• wherein the main control unit comprises a plurality of control subunits, the plurality of control subunits comprising:
• a main function subunit configured to obtain the sampling data of the motor and generate the motor control signal according to the sampling data of the motor;
• a monitoring subunit configured to perform information diagnosis, generate diagnostic information, obtain process data of the main function subunit to monitor a state of the main function subunit, generate a motor safety control signal according to the diagnostic information, enable or disable control information, and control information enabling the motor to be in a safe state;
• and
• a first co-processing subunit configured to determine a motor drive state according to the sampling data and output a final motor control signal according to the motor control signal output by the main function subunit, the motor safety control signal output by the monitoring subunit, and the motor drive state.
