摘要： A suspension control for vehicle dampers uses a trimset value to compensate signals from relative body/wheel position sensors associated with the dampers. Each trimset value is determined by recording a sensor value with the body and wheel in a predetermined relative state, such as by lifting the vehicle until the associated wheel is free of the ground and hanging in a low limit position determined by the suspension apparatus. In vehicle operation, the trimset value is used as an offset to the relative position sensor signal to accurately determine damper position relative to its compression and rebound limit positions. When the damper is within a predetermined bump stop region near either of the compression and rebound limit positions, a bump stop value is determined and applied to the damper to provide a high minimum damping level creating an electronic bump stop for the damper.

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.

摘要： A vehicle suspension system is responsive to an active brake signal from a brake system indicating the application of a greater braking force to one front corner brake than to the other front corner brake to affect vehicle yaw rate. The vehicle suspension system determines the relative velocities of the front corner suspension adjacent the front corner brake receiving the greater braking force and the diagonally opposed rear corner suspension and further determines a compression damping command for the front corner suspension and a rebound damping command for the rear corner suspension. While the active brake signal is present, the suspension control applies the compression damping command for the front corner suspension when its relative velocity indicates that it is in compression. While the active brake signal is present, the suspension control also applies the rebound damping command for the rear corner suspension when its relative indicates that it is in rebound.

摘要： Method for determining a present coil temperature of a coil of a magnetorheological (MR) damper of an operating automotive vehicle, wherein the coil is powered by an output of a controller connected to the coil through a conductor. One step includes calculating a coil-plus-conductor resistance from the voltage and the current of the output of the controller when the controller applies a test current to the coil and the conductor. Another step includes calculating the present coil temperature using at least the coil-plus-conductor resistance and compensating for the resistance of the conductor.

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 magnetorheological (MR) damper includes a damper tube, a movable non-MR damper piston, and a non-movable MR damper piston. The damper tube has substantially hermetically separated first and second chambers, wherein the first chamber contains a non-MR fluid and the second chamber contains an MR fluid. The non-MR damper piston is located in the first chamber and is slidable with respect to the damper tube. The MR damper piston has a longitudinal axis and an electric coil, is located in the second chamber, and is fixedly attached to the damper tube. Sliding the non-MR damper piston with respect to the damper tube causes movement of at least some of the MR fluid longitudinally past the electric coil.
