First Claim
1. A method for localizing an installation position of at least two wheels on a vehicle, comprising the steps:
- receiving a first radio signal of a first first sensor mounted on one wheel of the at least two wheels, wherein the first radio signal indicates a position of the wheel;
receiving a second radio signal of a second first sensor mounted on a further wheel of the at least two wheels, wherein the second radio signal indicates a position of the further wheel;
receiving a first measurement value of a first second sensor that measures an angular position of a first wheel of the at least two wheels and that is associated with a certain first point of the vehicle;
receiving a second measurement value of a second second sensor that measures the angular position of a second wheel of the at least two wheels and that is associated with a certain second point of the vehicle;
determining a first phase position of the first radio signal relative to the first measurement value, as well as determining a second phase position of the first radio signal relative to the second measurement value; and
,if the first phase position and the second phase position each remain within a predetermined tolerance range in a predetermined observation interval, determining the installation position of the at least two wheels by measuring a field strength of the first radio signal and a field strength of the second radio signal by means of a receiving device on the vehicle, wherein the respective measured field strength characterizes a distance of the receiving device on the vehicle from the first first sensor and from the second first sensor,wherein the predetermined observation interval contains at least one of a predetermined number of revolutions of at least one of the first wheel and the second wheel of the at least two wheels and a predetermined time interval.

Abstract
The invention relates to a method and an arrangement for locating the installation position of at least two wheels (2a-2d) on a vehicle (1). A first radio signal of a first first sensor (4a) which is mounted on a wheel and a second radio signal of a second first sensor (4b) which is mounted on another wheel of the at least two wheels are received. Furthermore, a first measurement value of a first second sensor, which measures an angular position of a first wheel, is received, and a second measurement value of a second second sensor (5c), which measures an angular position of a second wheel of the at least two wheels, is received. If a first phase position of the first radio signal remains within a specified tolerance range in relation to the first measurement value and a second phase position of the first radio signal remains within a specified tolerance range in relation to the second measurement value, a unique allocation by means of an angular comparison is not possible such that the installation position of the sensors or the paired wheels is located by means of a field strength measurement (FS4a, FS4c) of the first radio signal (S4a) and the second (S4c) radio signal.
