Method and device for locating the installation position of vehicle wheels in a motor vehicle

A method for localizing installation positions of vehicle wheels in a motor vehicle, in which at least one vehicle wheel has wheel electronics, which comprises the steps of:

• determining, via the wheel electronics, a first rotation angle position for the vehicle wheel associated with the wheel electronics;
• sending a transmission signal with a first rotation angle information item being dependent on the first rotation angle position ascertained;
• determining, via the motor vehicle, second rotation angle positions for the vehicle wheels, and the second rotation angle positions are taken as a basis for generating second rotation angle information items;
• aligning the first rotation angle information item with the second rotation angle information items;
• and
• determining an installation position of the vehicle wheel associated with the wheel electronics on a basis of an alignment.

An apparatus for localizing installation positions of vehicle wheels in a motor vehicle, the apparatus comprising:

• a reception device disposed in the motor vehicle;
• at least one wheel electronics unit disposed in a vehicle wheel and configured for determining a first rotation angle position for the vehicle wheel and for sending a first rotation angle information item being dependent on the first rotation angle position ascertained, to said reception device;
• at least one rotation speed sensor disposed in the motor vehicle, said rotation speed sensor determining respective second rotation angle positions for respective associated vehicle wheels and taking the respective second rotation angle positions as a basis for generating second rotation angle information items;
• and
• an evaluation device for aligning the first rotation angle information item with the at least two of the second rotation angle information items and taking an alignment as a basis for determining the installation position of the vehicle wheel associated with said wheel electronics unit.

A vehicle, including an automobile, comprising:

• a plurality of vehicle wheels;
• a tire information apparatus having an apparatus for localizing installation positions of said vehicle wheels, said apparatus containing:
• a reception device disposed in the vehicle;
• at least one wheel electronics unit disposed in said vehicle wheels and configured for determining a first rotation angle position for a vehicle wheel and for sending a first rotation angle information item being dependent on the first rotation angle position ascertained, to said reception device;
• at least one rotation speed sensor disposed in the vehicle, said rotation speed sensor determining respective second rotation angle positions for respective associated said vehicle wheels and taking the respective second rotation angle positions as a basis for generating second rotation angle information items;
• and
• an evaluation device for aligning the first rotation angle information item with the at least two of the second rotation angle information items and taking an alignment as a basis for determining the installation position of said vehicle wheel associated with said wheel electronics.
