    Abstract: The present invention provides a motor control system and a vehicle. The motor control system (1) includes a motor drive module (10), a multi-core processing module (20), and a safety logic module (30). The multi-core processing module (20) includes a main function core (21) and a lockstep monitoring core (22). The main function core (21) is configured to obtain sampling data, and when any one of the sampling data, a running status of the main function core (21), a motor control signal, and a running status of a motor is abnormal, the lockstep monitoring core (22) outputs a safety trigger signal; and the safety logic module (30) is configured to output an instruction for prohibiting execution of the motor control signal to the motor drive module (10) when receiving the safety trigger signal.

    Abstract: A motor control system and a motor control device are provided. The system includes a master control module, a drive module, and a monitoring module. The master control module is configured to output a low-voltage drive signal to the drive module, the drive module converts the low-voltage drive signal into a high-voltage drive signal and outputs the high-voltage drive signal to a power unit, and the power unit outputs, according to the high-voltage drive signal, a power supply drive signal provided by a high-voltage battery. The monitoring module is electrically connected with the master control module and the drive module, and is configured to acquire the low-voltage drive signal, and output a fault signal to the master control module when the low-voltage drive signal is abnormal, to control the master control module to stop outputting the low-voltage drive signal. The monitoring module includes at least an auxiliary power supply, and the auxiliary power supply is independent of the master control module and provides a working power supply for the monitoring module.
