Four wheel steering compensation for low coefficient of friction surface

A method directed to improving the stability of a motor vehicle (12) having front and rear steering capabilities includes determining a coefficient of friction of the road surface with which the motor vehicle (12) is engaged and adjusting a phase gain function of a rear steering mechanism (16) to co...

Beschreibung
Zusammenfassung:	A method directed to improving the stability of a motor vehicle (12) having front and rear steering capabilities includes determining a coefficient of friction of the road surface with which the motor vehicle (12) is engaged and adjusting a phase gain function of a rear steering mechanism (16) to compensate for the steerability of the motor vehicle (12) over the road surface. A system (10) for improving the stability of a motor vehicle (12) having front and rear steering capabilities includes a control unit (18), a front steering mechanism (14) in informational communication with the control unit (18), and a rear steering mechanism (16) in informational communication with the control unit (18). The rear steering mechanism (16) is responsive through the control unit (18) to road conditions of the road surface.
