Steer-by-wire system with steering feedback
First Claim
1. A steer-by-wire system for a vehicle having a road wheel capable of turning and a steering device capable of receiving a steering input from and transmitting a steering feedback to a driver of the vehicle, comprising:
- a steering subsystem including a steering sensor coupled to the steering device and adapted to sense steering factors of the steering input, and a steering actuator coupled to the steering device and adapted to receive a steering feedback signal and to generate the steering feedback to the driver;
a turning subsystem including a turning actuator coupled to the road wheel and adapted to receive a turning control signal and to adjust a turning angle of the road wheel, and a turning sensor coupled to the turning actuator and adapted to sense turning factors of the turning actuator;
a feedback selector adapted to receive a feedback selection from the driver; and
a controller subsystem connected to said steering sensor, to said turning sensor, and to said feedback selector, and adapted to produce the turning control signal based on the steering factors thereby controlling the turning angle of the road wheel and to produce the steering feedback signal based on the steering factors, the turning factors, and the feedback selection thereby controlling the steering feedback of the steering device.

Abstract
A steer-by-wire system of the preferred embodiment of the invention includes a steering subsystem, a turning subsystem, and a controller subsystem. The steering subsystem further includes a steering sensor to sense steering factors of a steering input, and a steering actuator to generate a steering feedback. The turning subsystem further includes a turning actuator to adjust a turning angle of a road wheel of the vehicle, and a turning sensor to sense turning factors of the turning actuator. The controller subsystem is connected to the steering sensor and to the turning sensor and controls the turning actuator and the steering actuator.
