A yaw rate haptic torque is ... 10/12/06 - 20060229782 - Vehicle-trailer stability and handling performance improvement using rear-wheel steering control A vehicle steering control system for a vehicle/trailer combination that provides rear-wheel steering assist to improve the vehicle/trailer combination stability and handling performance. The control system provides an open-loop feed-forward control signal based on hand-wheel angle and vehicle speed. The control system includes a vehicle yaw rate command interpreter that ... 01/26/06 - 20060020382 - Adaptive compensation of rear-wheel steering control using vehicle dynamics parameter estimation An active rear-wheel vehicle steering control system that employs both open-loop and closed-loop control, where the open-loop and closed-loop control include adaptive compensation sub-systems that compensate for changes in vehicle dynamic parameters. The control system includes a dynamic parameter estimation sub-system that provides an estimated front-wheel cornering compliance and rear-wheel ... 01/19/06 - 20060015230 - Power steering apparatus A power steering apparatus according to the present invention is constructed to calculate a rate of change of steering speed detected by steering speed detecting means and judge whether the calculated rate of change is smaller than or equal to 0 or not, and reduce a gain of feedback control ... 09/29/05 - 20050216157 - Steering characteristic control apparatus and method for a vehicle A steering characteristic control apparatus and method for a vehicle is disclosed which can carry out behavior control of the vehicle regarding a steering characteristic and so forth appropriately in accordance with the type of turning and the road surface situation. To this end, if the steering characteristic of the ... ### FreshPatents.com Support |
