The steering-by-wire motor is connected with the steering-by-wire controller and is used for interacting with the steering-by-wire controller and executing a steering signal sent by the steering-by-wire controller.
6. The steer-by-wire system of claim 5, wherein the steer-by-wire further comprises a second angle sensor,
The second angle sensor is connected with the steer-by-wire controller and is used for collecting steering angle signals of the steer-by-wire motor and sending the steering angle signals to the steer-by-wire controller.
7. The steer-by-wire system of claim 5 or 6, wherein the steer-by-wire motor is hard-wired to the steer-by-wire controller.
8. The steer-by-wire system of claim 1, wherein the steer-by-wire controller comprises a main electronic control unit and a redundant electronic control unit,
The main electric control unit is connected with the steering column actuator and the steer-by-wire machine and is used for receiving vehicle information sent by the preset whole vehicle controller and generating the hand force feedback signal and the steering signal;
The redundant electric control unit is connected with the steering column actuator and the steer-by-wire machine and is used for receiving vehicle information sent by the preset whole vehicle controller when the main electric control unit fails and generating the hand force feedback signal and the steering signal.
9. A vehicle chassis comprising a steer-by-wire system according to any of claims 1-8.
10. A vehicle comprising the vehicle chassis of claim 9.
