Shock absorber damping force control device for motor vehicle calculates damping forces required to suppress roll and pitch based on models of individual and front and rear wheels

摘要

A controller (20) calculates the damping force for each wheel required to suppress the vibration of the car body in the roll direction, based on a model of the individual wheels of the vehicle. The controller also calculates a second damping force for each wheel required to suppress the vibration of the car body in the pitch direction, based on a model of the front and rear wheels of the vehicle. A final required damping force is calculated for each wheel based on the two calculated damping forces. A control signal is output to each shock absorber so that the required damping force is exerted. Independent claims are included for two further damping force control devices.
