A system for initializing a steering wheel in a steer-by-wire vehicle includes a steering wheel, a torque feedback actuator, a steering wheel angle sensor, and a controller. The controller is adapted to calculate a corrected steering wheel angle based upon the relative angular positions of the road wheels and the steering wheel as measured by the respective sensors. The controller then controls the torque feedback generator to rotate the steering wheel into a corrected position such that the torque feedback generator rotates the steering wheel a minimum angle. The controller issues a warning signal in response to any resistance to the correction, including interference from the vehicle driver.

Method to initialize steering wheel in a steer-by-wire system

The present invention includes a power drive electronics apparatus connected between a frequency variable generator and an electric motor. The power drive electronics apparatus includes a three-phase diode rectifier having a three-phase AC input, a positive DC output terminal and a negative DC output terminal. A capacitor is connected between the positive DC output terminal and said negative DC output terminal. The three-phase AC input is operably connected to the electric motor and the positive DC output terminal is operably connected to the frequency variable generator's rotor winding. The power drive apparatus also includes a diode having an anode and a cathode, wherein the cathode is connected to the positive DC output terminal of the three-phase diode rectifier, and the anode is connected to a battery.

A drive assembly including an electric motor and frequency variable generator for use with a multi-axle vehicle. The vehicle generally includes an engine driving a first axle and a drive assembly with an electric motor driving a second drive axle. The drive assembly includes a frequency variable generator with an input shaft driven by the engine and the electric motor electrically communicates with the generator to receive output power from the generator. Other details of selected embodiments of the invention include the frequency variable generator having a rotor coupled to rotate with the engine output shaft and a stator electrically connected to the electric motor. An inverter is electrically connected to an electrical power source, such as a battery or the frequency variable generator, as well as to the rotor. A controller communicates with the inverter and is configured to control the magnitude and frequency of the power communicated from the inverter to the rotor winding.
