Method for assigning tire pressure measurement devices in a motor vehicle to wheel positions and device for measuring the tire pressure
First Claim
1. Method for assigning tire pressure measurement devices in a motor vehicle to wheel positions, wherein when the motor vehicle is traveling, wheel parameters and assigned wheel positions are recorded by means of an existing driver support system located in the motor vehicle and used in the driver support system as bend data to determine whether a left-hand or right-hand bend is traveled and which bend is then being traveled, with the bend data being transferred to an analysis unit, when a bend is identified, assignment mode is activated for the tire pressure measurement devices, a sensor in each tire is used to measure a physical variable proportion to the speed of the relevant wheel and the value of the physical variable is sent along with identification codes of the relevant tire pressure measurement devices to the analysis unit in wireless fashion, and in the analysis unit the bend data is collated with the variables measured by the sensors in the tire or variables calculated from these and used to assign identification codes and therefore the tire pressure measurement devices to wheel positions.

Abstract
When a vehicle travels a bend, tire pressure measurement devices (2) are assigned to wheel positions. For this purpose, it is determined by means of ABS (4) whether it is a left-hand or right-hand bend. Wheel revolution counts are then measured in each tire and sent along with identification codes to a central analysis unit (3). There the wheel revolution counts are collated with the bend data determined by the ABS. The two higher wheel revolution counts are then assigned to the side of the vehicle on the outside of the bend and the two lower wheel revolution counts are assigned to the other side of the vehicle.

6. Arrangement for measuring the tire pressure of a plurality of wheels of a motor vehicle, comprising:
-
a sensor arrangement within each wheel to be measured coupled with a data transceiver unit;
wherein the sensor arrangement comprises a pressure sensor and a sensor for measuring the physical variable proportional to the speed of the wheel;
a driver support system for receiving and evaluating a plurality of travel information;
an evaluation unit being coupled with a data transceiver for transmitting and receiving data from said sensor arrangements, wherein said driver support system provides bend data to determine whether a left-hand or right-hand bend is traveled to said evaluation unit; and
said evaluation unit assigns from the physical variable proportion to the speed of the relevant wheel the received tire pressure value to a respective wheel within the motor vehicle. - View Dependent Claims (7, 8, 9, 10, 11, 12)
