Abstract
A motor control system and a vehicle reliably perform a three-phase active short circuit on a motor when a single-point power source fails. The motor control system includes a bus capacitor and a motor. The motor is connected to a positive direct current bus and a negative direct current bus through three phases of inverter bridges, the positive direct current bus and the negative direct current bus are respectively connected to a positive terminal and a negative terminal of the bus capacitor, and each phase of inverter bridge includes an upper bridge arm connected to the positive direct current bus and a lower bridge arm connected to the negative direct current bus. In addition, the motor control system further includes: an upper gate drive circuit, a lower gate drive circuit, a first power supply unit, and a second power supply unit.
