Abstract:
In a vehicle with four corner suspensions, a suspension control method according to the steps of:sensing vehicle speed;monitoring steering wheel angle;monitoring steering wheel velocity;responsive to the vehicle speed and the steering wheel velocity, determining a signal indicative of a transient turning maneuver of the vehicle;responsive to the signal and the steering wheel angle, determining compression damping commands for two of the corner suspensions on a first side of the vehicle that tends to have suspension compression during the transient turning maneuver and determining rebound damping commands for two of the corner suspensions on a second side of the vehicle that tends to have suspension rebound during the transient turning maneuver;monitoring relative velocity of each corner suspension;applying the compression damping commands for the two corner suspensions on the first side of the vehicle when the relative velocities for those two corner suspensions indicate that they are in compression and terminating the compression damping commands for the two corner suspensions on the first side of the vehicle when the relative velocities for those two corner suspensions indicate that they are in rebound; andapplying the rebound damping commands for the two corner suspensions on the second side of the vehicle when the relative velocities for those two corner suspensions indicate that they are in rebound and terminating the rebound damping commands for the two corner suspensions on the second side of the vehicle when the relative velocities for those two corner suspensions indicate that they are in compression.
