2results about How to "Implement redundant control" patented technology

The application relates to an electronic and electrical system of a vehicle and the vehicle. The electronic and electrical system of the vehicle comprises a mobile data center, a main area controller and a backup area controller; wherein different area controllers are arranged in different sub-areas of the vehicle, the main area controller is connected with a main bus network segment, and the backup area controller is connected with a backup bus network segment; the main area controller is configured to communicate with the mobile data center, a main braking assembly and a main steering assembly in the main bus network segment, and the backup area controller is configured to communicate with the mobile data center, a backup braking assembly and a backup steering assembly in the backup bus network segment. The scheme can realize redundant control of vehicle braking and vehicle steering, and improve the safety of vehicle driving.

The application discloses a control method of a six-phase permanent magnet synchronous motor, two common three-phase permanent magnet synchronous frequency converters are used to connect symmetric stator windings of the six-phase permanent magnet synchronous motor, two three-phase permanent magnet synchronous motors are equivalently driven, then collaborative control is performed between the two master-slave frequency converters, power balance of the two equivalent three-phase permanent magnet synchronous motors is realized, and thus the six-phase permanent magnet synchronous motor can be stably operated. In the case of failure of one of the frequency converters, the other frequency converter can normally drive the motor, redundancy control is realized, and the system stability and reliability are improved.
