摘要： A motor control system of an electric vehicle, a controlling method for the motor control system and an electric vehicle are provided. The motor control system includes: an IGBT module, connected with a motor of the electric vehicle; a detection module, configured to detect a motor speed; a drive module, configured to drive IGBTs in the IGBT module to turn on or off so as to control the motor to work or stop working; a first control module; a second control module communicated with the first control module; and a channel selection module, configured to select a channel of the second control module when the first control module has a fault. When the second control module is selected, it sends a second control signal to the drive module according to the motor speed at a predetermined time before the first control module has the fault, so as to control the motor to stop working.

摘要： The present disclosure discloses an integrated controller, an electric drive assembly, and a vehicle. The integrated controller includes: a box; a control unit and a charging/discharging conversion unit that are arranged in the box; and a high-voltage interface assembly, including a high-voltage interface arranged on the box and a high-voltage connection member arranged in the box, the high-voltage connection member being connected with the high-voltage interface, the control unit, and the charging/discharging conversion unit to receive and distribute a high-voltage battery signal. The integrated controller may cancel arrangement of a high-voltage distribution box, which reduces a demand for a high-voltage wiring harness, reduces costs, and saves vehicle space.
