The present invention provides a system for compensating understeer and oversteer
in a vehicle having a steer by wire system. The system includes a driver interface
system, a sensor system, a controller, and a road wheel steering actuation system.
The driver interface system receives steering input from the driver. The sensor
system senses the steering input and generates a steering control signal that is
received by the controller. The controller determines if an understeer or oversteer
condition exists and generates an appropriate steering assist signal that is then
communicated to the road wheel steering actuation system. In response to the steering
assist signal, the road wheel steering actuation system adjusts the road wheel
angle to compensate for the understeer or oversteer condition.
