Abstract
A control system for a plurality of motor vehicle chassis subsystems comprises a reference model, a state estimator, a feedforward controller, and a feedback controller. The reference model computes desired states of the chassis subsystems. The state estimator estimates actual states of the vehicle. The feedforward controller computes a control value based on input from the reference model, and the feedback controller computes a control value by comparing the estimates of actual states with the desired states.

A control system for a plurality of motor vehicle chassis subsystems, the control system comprising:
- a reference model which computes desired states of the chassis subsystems;
- a state estimator which estimates actual states of the vehicle;
- a feedforward controller which computes a control value based on input from the reference model;
- a feedback controller which computes a control value by comparing the estimates of actual states with desired states;
- and
- means for affecting the chassis subsystems based on the control value computed by the feedforward controller and based on the control value computed by the feedback controller.
A method of controlling a plurality of motor vehicle chassis subsystems, the method comprising:
- computing desired states of the chassis subsystems;
- estimating actual states of the vehicle;
- computing a control value based on the desired states of the chassis subsystems;
- computing a control value by comparing the estimates of actual states with desired states;
- and
- affecting the chassis subsystems based on the control value computed by the feedforward controller and based on the control value computed by the feedback controller.
A control system for a first motor vehicle chassis subsystem, the control system comprising:
- a reference model which computes a desired state of a second chassis subsystem;
- a state estimator which estimates actual states of the vehicle;
- a feedforward controller which computes a control value based on input from the reference model;
- a feedback controller which computes a control value by comparing the estimates of actual states with the desired state;
- and
- means for affecting the first chassis subsystem based on the control value computed by the feedforward controller and based on the control value computed by the feedback controller.
