Device for determining the distance between vehicle body and vehicle wheel
First Claim
1. A device for determining a vertical distance between a body of a vehicle and at least one wheel adjustably mounted thereto, said vehicle including a coupling component coupled to said wheel and to said body such that a change in the vertical distance between said wheel and body causes the relative position of said coupling component to change with respect to said body, said device comprising:
- a first inclination sensor attached to the vehicle body, said first sensor generating first inclination signals indicative of the inclination of the vehicle body with respect to a reference plane;
a second inclination sensor attached to said coupling component, said second sensor generating second inclination signals indicative of the inclination of said coupling component with respect to said reference plane; and
a control unit for receiving said first and second inclination signals transmitted by said inclination sensors, wherein said control unit determines from said first and second inclination signals a distance signal which is correlated to the vertical distance between the vehicle wheel and the vehicle body, wherein said control unit determines a differential signal and assigns a said vertical distance to said differential signal correlated to that vertical distance.

Abstract
The intention is to specify a simplified design for a device which is used in vehicles for determining a vertical distance between a vehicle body and at least one vehicle wheel which is adjustably mounted thereon.
In the device according to the invention, a first inclination sensor which generates first inclination signals which are correlated to the inclination of the vehicle body with respect to a reference position, and transmits them to a control unit, is attached to the vehicle body. Attached to a coupling component which is adjusted, together with the vehicle wheel, relative to the vehicle body, is a second inclination sensor which generates second inclination signals which are correlated to the inclination of this coupling component with respect to a reference position, and transmits them to the control unit. The control unit then determines from the inclination signals of the inclination sensors a distance signal which is correlated to the vertical distance between the vehicle wheel and the vehicle body.
