Abstract
Suspension apparatus provides a real time suspension tuning control for a motor vehicle. An actuator is connected to exert a variable force between the vehicle body and wheel. A control derives a control signal for the actuator from a linear combination of vehicle state variables derived from sensed vehicle variables, the linear combination being characterized by gains determining the relative contribution of each state variable to the control signal. The control further stores in memory a plurality of alternatives sets of gains, with each stored set of gains comprising gain values tending to produce a different suspension performance. The control is responsive to one of the sensed vehicle varibles in real time to select between the alternative sets of gains in deriving the control signal. The suspension tuning characteristics are thus easily and quickly changed in emphasis between isolation, wheel control and body attitude control in real time vehicle operation.
