Abstract

An apparatus and method for controlling the undercarriage of a vehicle with means for adjusting vehicle parameters, such as, for example, the spring travel or the spring constant, in accordance with computed control signals. A signal receiving means receives signals from the environment of the vehicle and converts the signals into environmental signals. A signal processing means determines vehicle-related data from the environmental signals and a computing means computes the control signals for the vehicle control system with the aid of the vehicle-related data.

Claims

1. A apparatus for controlling the undercarriage of a vehicle, said apparatus comprising

a means for adjusting undercarriage parameters in accordance with computed control signals,

signal receiving means for receiving signals from an environment surrounding the vehicle and for converting the received signals into environmental signals,

signal processing means for determining road-related data from said environmental signals, and

computing means for computing control signals for the undercarriage control system based on said road-related data and for controlling the adjustment of said undercarriage parameters.

2. An apparatus according to claim 1, including means for measuring transient vehicle-specific data, the computing means utilizing said transient vehicle-specific data in computing the control signals.

3. An apparatus according to claim 1, wherein the signal processing means determines the road-related data with the aid of digital image processing methods and algorithms.

4. An apparatus according to claim 1 including an image receiving means for transmitting images of the environment of the vehicle to the signal receiving means.

5. An apparatus according to claim 4, wherein the image receiving means is positioned in a high position in the interior of the vehicle between the rear-view mirror and the windshield.

6. An apparatus according to claim 4 wherein the image receiving means comprises a camera.

7. An apparatus according to claim 4 wherein the signal processing means determines a pitch angle of the vehicle.

8. A method for controlling the undercarriage of a vehicle which includes an undercarriage control system, said method comprising:

receiving signals from an environment surrounding the vehicle,

converting the received signals into environmental signals

determining road-related data from the environmental signals;

computing control signals for the undercarriage control system using the road-related data; and

adjusting vehicle parameters using the control signal.

9. A vehicle including an apparatus for controlling an undercarriage of the vehicle, said apparatus comprising:

a means for adjusting undercarriage parameters in accordance with computed control signals,

a signal receiving means for receiving signals from an environment surrounding the vehicle and for converting the received signals into environmental signals,

a signal processing means for determining road-related data from said environmental signals, and

computing means for computing control signals based upon said road-related data and for controlling adjustment of said undercarriage parameters.

10. A vehicle according to claim 9, including means for measuring transient vehicle-specific data, the computing means utilizing said transient vehicle-specific data in computing the control signals.

11. A vehicle according to claim 9, wherein the signal processing means determines the road-related data with the aid of digital image processing methods and algorithms.

12. A vehicle according to claim 9, including an image receiving means for transmitting images of the environment of the vehicle to the signal receiving means.

13. A vehicle according to claim 9, wherein the image receiving means is positioned in a high position in the interior of the vehicle, between the rear-view mirror and the windshield.

14. A vehicle according to claim 9, wherein the image receiving means comprises a camera.

15. A vehicle according to claim 9, wherein the signal processing means determines a pitch angle of the vehicle.
