Abstract
The present invention provides a controller that is operative to receive body and wheel accelerations from the vehicle. The controller uses the body accelerations to calculate a Heave, Pitch and Roll (HPR) control signal. In addition, the controller uses the wheel accelerations to calculate a wheel control signal. The calculated wheel control signal and the HPR control signal are combined to create a damper control signal. Based on the damper control signal, the controller is able to move a wheel of the vehicle in the appropriate manner to handle various driving conditions.
Claims20
A method for controlling a damper in a vehicle suspension system, the method comprising:
- receiving body accelerations from a vehicle;
- calculating a control signal for a damper based on said received body accelerations;
- receiving wheel acceleration from the vehicle;
- calculating a wheel control signal for the damper based on said received wheel acceleration;
- combining the control signal and the wheel control signal to create a damper control signal;
- and
- adjusting the damper of the vehicle based on the damper control signal.
A system for controlling a damper in a vehicle suspension system, the system comprising:
- a controller;
- a plurality of accelerometers coupled to the controller, wherein the plurality of accelerometers are operative to transmit body accelerations to the controller;
- a sensor coupled to the controller, wherein the sensor is operative to transmit a wheel acceleration to the controller;
- a damper coupled to the controller and a vehicle;
- and
- wherein the controller is operative to receive the body accelerations and the wheel acceleration, calculate a Heave, Pitch and Roll (HPR) control signal in response to receiving the body accelerations for the damper, calculate a wheel control signal in response to receiving the wheel acceleration for the damper, combine the HPR control signal and the wheel control signal to create a damper control signal and adjust the damper of the vehicle based on the damper control signal.
A controller for controlling a damper in a vehicle suspension system, the controller comprising:
- means for receiving body accelerations and wheel accelerations from a vehicle;
- means for calculating a Heave, Pitch and Roll (HPR) control signal for a damper in response to receiving the body accelerations;
- means for calculating a wheel control signal for the damper in response to receiving the wheel accelerations;
- means for combining the HPR control signal and the wheel control signal to create a damper control signal;
- and
- means for adjusting the damper of the vehicle based on the damper control signal.
