摘要： A rear steer control for a motor vehicle considers vehicle velocity in three ranges and provides an out of phase rear steer angle in open loop control within a low velocity range for oversteer assistance of parking and similar vehicle maneuvers, an in phase rear steer angle in closed loop control responsive to vehicle yaw rate within a high velocity range for understeer vehicle stability assistance, and a steer angle in closed loop control responsive to vehicle yaw rate within an intermediate velocity range. In a preferred embodiment, the closed loop control in the high velocity range may be combined with an open loop control. The control further provides supplemental throttle adjustments in coordination with the rear steer control for increased traction and stability in a turn.

摘要： A vehicle chassis control stores first and second calibrated values of a predetermined braking parameter and a steering correction parameter. The control includes apparatus for detecting a split coefficient condition with respect to the road surface; and, when it does and a braking signal is present, the control actuates braking apparatus for a wheel on the side of the vehicle having the higher coefficient of friction with the first calibrated value of the predetermined braking parameter and simultaneously actuates the steering apparatus with a steering correction to compensate for yaw induced by braking on the split coefficient road surface. If the steering correction is not available, however, the braking apparatus is actuated for the wheel having the higher coefficient of friction with the second calibrated value of the predetermined braking parameter without simultaneously actuating the steering apparatus with the steering correction. The steering correction may have an open loop part derived from a difference between wheel slips of two wheels on opposite sides of the vehicle and/or a closed loop part derived from yaw rate, side slip and/or side slip rate error.
