    摘要: The present invention involves a steer-by-wire actuating system and method of actuating road wheels of a vehicle with the steer-by-wire actuating system. The system includes a steering linkage assembly including an input shaft, an output shaft, and a gear unit linking the input shaft and the output shaft for linear movement of the output shaft to rotate the road wheels of the vehicle. The system further comprises a microcontroller for controlling an actuation strategy including normal and fault detection modes. The microcontroller is configured to receive a steering signal indicative of steering input at a steering interface. The system further includes first and second power electronic drivers in electrical communication with the microcontroller for electric power supply. The system further includes a first motor and a second motor for simultaneous operation with the steer-by-wire steering device. The first motor is in electrical communication with the first power electronic driver to receive electric power therefrom and the second motor is in electrical communication with the second power electronic driver to receive electric power therefrom. The first and second motors are connected to the input shaft for movement thereof to rotate the road wheels based on the steering signal. The first and second motors are configured to cooperate simultaneously to rotate the road wheels during the normal mode.

    摘要: A steer-by-wire system of the preferred embodiment of the invention includes a steering sensor, a turning subsystem, a vehicle sensor, and a controller subsystem. The turning subsystem further includes a first turning actuator to adjust a turning angle of a first road wheel, a first turning sensor to sense first turning factors of the first turning actuator, a second turning actuator to adjust a turning angle of a second road wheel, and a second turning sensor to sense second turning factors of the second turning actuator. The controller subsystem is connected to the steering sensor, to the first turning sensor, to the second turning sensor, and to the vehicle sensor. The control subsystem independently controls the first turning actuator and the second turning actuator.
