摘要： A traction control for a motor vehicle responds to detection of a rough road surface so as to shift control away from propulsion power reduction and toward brake control to an over-spinning driven wheel when the rough road surface is detected. This better adapts the traction control to a road surface that may have a high coefficient of friction but produces intermittent loss of traction due to wheel hop or normal force fluctuations due to the rough road surface. The lower power reduction is obtained by increasing a target brake pressure used to derive a brake pressure error signal from which from which a power reduction command is derived. A delta target brake pressure may also be increased to provide a higher target velocity for the driven wheel propulsion. For even higher levels of road roughness, the traction control reduces the gain of time derivative of a difference between a rotational wheel acceleration of the driven wheel and an undriven wheel rotational acceleration that contributes to the brake modulation, since wheel accelerations are of less use in controlling traction on such a road surface.

摘要： A variable power steering system for a motor vehicle is responsive to an activity signal from a vehicle stability enhancement (VSE) system and a lateral surface coefficient of friction estimator to modify steering assist in an amount dependent on the estimated surface coefficient when the vehicle stability enhancement system is active. The modification is phased in and out with slew limiting in steps also determined by the estimated lateral surface coefficient, with both the maximum modification and the step size varying inversely with lateral surface coefficient. The system preferably determines offset current values for the VSE system and estimated lateral acceleration, as well as for any other vehicle traction limit handling systems such as anti-lock braking (ABS) or traction control (TCS) and chooses the greatest in magnitude as a road surface adaptation offset current for addition to a vehicle speed offset current to provide a total current signal for the modification.

摘要： A vehicle brake control providing understeer correction through an increase in differential brake pressure favoring the inside wheel applies the increase, in the absence of anti-lock braking activity, across the rear wheels unless one or more sensors indicates a likely low traction condition on the inside rear wheel, in which case the increase is applied to the front pair of wheels. Preferred sensors include a suspension position sensor for the inside rear wheel or other sensor derived information from a suspension control system that indicates large body roll in a turn together with forward body pitch. In the absence of a suspension control system, preferred sensors include vehicle lateral and longitudinal accelerometers indicating vehicle roll and pitch together with a steer angle sensor indicating a significant turn. An indication could also be derived from a normal force sensor on the wheel or normal force information derived from other sensors such as a tire pressure sensor.

摘要： A vehicle suspension control stores, for each direction of vehicle lateral acceleration, a first set of enhanced vehicle damping commands that provide enhanced damping in compression for the suspension dampers on the outside of a turn and in rebound on the inside of the turn and a second set of enhanced body damping commands that provide enhanced damping in compression and rebound on both sides of the vehicle. Responsive to a sensed vehicle lateral acceleration, the control applies the first set of enhanced damping commands to the suspension dampers if a sensed steering angle is in the same direction as the sensed lateral acceleration and applies the second set of enhanced body damping commands to the suspension dampers if the sensed steering angle is in the opposite direction as the sensed lateral acceleration. The control may derive a demand force command for each of the dampers from the determined relative velocities of the dampers and apply each of the demand force commands to its respective damper only when a comparison of the direction of the demand force command with the sensed relative velocity of the damper indicates that a force corresponding to the demand force command can be effectively exerted by the damper. The enhanced body damping commands are applied to the suspension dampers without regard for any application of the demand force command.

摘要： A vehicle suspension control includes a vehicle body control responsive to body/wheel velocity at the corners of the vehicle body to derive a demand force command for dampers at each corner of the vehicle body for vehicle body control and applies each of the derived demand force commands to its respective damper only when a comparison of the direction of the demand force command with the sensed relative velocity of the damper indicates that a force corresponding to the demand force command can be effectively exerted by the damper. But the suspension control also includes a vehicle stability control responsive to an indicated vehicle lateral acceleration in a turn to determine, independently of the vehicle body control, a stability compression damping command for the suspension dampers on the side of the vehicle opposite the direction of the lateral acceleration and a stability rebound damping command for the suspension dampers on the side of the vehicle in the direction of the lateral acceleration. While the lateral acceleration is sensed, the vehicle stability control applies the stability compression damping command to the suspension dampers on the side of the vehicle opposite the direction of the lateral acceleration and the stability rebound damping command to the suspension dampers on the side of the vehicle in the direction of the lateral acceleration, without regard for the direction of demand force for any of the suspension dampers. The resulting stiffening of the suspension on the outside of the turning vehicle in compression and on the inside of the turning vehicle during rebound helps keep the tires of the vehicle firmly in contact with the road surface in spite of road surface irregularities.

摘要： A vehicle suspension control derives demand force commands from relative velocities of the suspension dampers at the corners of the vehicle and applies the demand force commands only when a force corresponding to the demand force command can be effectively exerted by the damper. The control is also responsive to a sensed vehicle handling event to derive a body control enhancement damping commands for selected suspension dampers and apply the body control enhancement damping commands without regard for the direction of demand force for the suspension dampers. Each body control enhancement damping command is derived from one or more measured vehicle dynamic variables associated with the sensed vehicle handling event and modified in magnitude in response to the direction and/or magnitude of the sensed relative velocity of damper to which the body control enhancement damping command is to be applied.
