摘要： A method for controlling a locking differential includes determining a temperature-dependent reference voltage at which a coil locks the differentia, determining an electric potential of a battery, using the battery to energize the coil and lock the differential, if the electric potential is equal to or greater than the reference voltage for a current temperature, and maintaining the differential unlocked, if the electric potential is less than the reference voltage.

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.
