Method for controlling the functions of an electronic driving stability program for a motor vehicle
First Claim
1. A method for controlling the functions of an electronic driving stability program for a motor vehicle with air springs, with an air spring control device, and with a body and at least two wheeled axles, the method comprising the steps ofdetermining through the air spring control device if at least one of the following two conditions applies:
- at least one of the wheeled axles is driven on a wedge of accumulated roadway material;
the vehicle is in a lifted platform situation in which the vehicle'"'"'s weight is supported by the vehicle body and at most one axle;
generating a deactivation signal if it is determined that at least one of the two conditions applies, anddeactivating the driving stability program in response to the deactivation signal, wherein the determination of whether at least one of the two conditions applies is carried out by means of distance sensors and wherein a deactivation signal is generated for a given wheel when an associated air spring is not pressurized and the distance between the bottom of the vehicle and at least one member of the group consisting of an underlying surface, the wheel axle associated with the vehicle wheel, and the vehicle wheel itself, exceeds a predefined set point value.

Abstract
In order to ensure problem-free operation of a vehicle when a wedge of material is formed between the roadway and the vehicle, a method for controlling the functions of an electronic driving stability program automatically activates or deactivates the driving stability program of the vehicle according to the respective operational situation of the motor vehicle. The driving stability program is automatically deactivated when the vehicle drives onto a wedge of material on the roadway. A determination whether the vehicle drives onto a wedge of material on the roadway is made by means of the air springs of the vehicle and associated distance sensor and/or pressure sensors.
