First Claim
1. A method for allocating identification codeswhich are contained in signals which are transmitted by components of a tire pressure monitoring system of a vehicle, said components being attached to wheels of the vehicle on which the vehicle is driving—
- said components being hereinafter referred to as wheel electronic devices—
to the positions of the wheels on the vehicle,wherein the wheel electronic devices each comprisea plurality of sensors,one of whichresponds to the tire pressure of the wheel,one of which provides information about the rolling direction of the wheel,one of which responds to shocks occurring on the wheel,a memory with the individual identification code of the particular wheel electronic devices stored therein,and a transmittertransmitting signals, which contain not only the individual identification code of the particular wheel electronic device but also information about the rolling direction of the particular wheel and about the occurrence of a shock on the same wheel, from the transmitter to a receiver which is provided with or connected to an antenna as well as provided with or connected to an evaluation device,and furthermore supplying a velocity signal indicating the driving speed of the vehicle is, to the evaluation device;
the evaluation device registers the identification codes and rolling direction information contained in the signals received,based on the registered rolling direction information, distinguishes identification codes pertaining to wheel electronic devices on wheels on the left-hand side of the vehicle from identification codes pertaining to wheel electronic devices on wheels on the right-hand side of the vehicle,distinguishes shocks about which it was informed by wheel electronic devices on the left-hand side of the vehicle from shocks about which it was informed by wheel electronic device'"'"'s on the right-hand side of the vehicle,measures the time interval between shock signals successively signaled by wheel electronic devices on the left-hand side of the vehicle or by wheel electronic devices on the right-hand side of the vehicle, respectively,multiplies the measured time interval by a velocity of the vehicle that was measured within the same time interval and signaled to the evaluation device,checks whether the length resulting from this multiplication corresponds to a given wheelbase of the vehicle within a specified tolerance,in case of correspondence, allocates the identification code contained in the signal having contained the information about the first one of two successively registered shocks on the left-hand side or of two successively registered shocks on the right-hand side of the vehicle to the left or right wheel, respectively, on a forward one of the two axles during forward driving and allocates the identification code contained in the signal having contained the information about the second one of the two successively registered shocks to the wheel on the rearward one of the two axles on the same side of the vehicle as that on the forward axle.

Abstract
Method for allocating identification codes which are contained in signals transmitted by components of a tire pressure monitoring system, said components being attached to wheels of the vehicle, to the wheel positions.
A plurality of sensors to the tire pressure, to the rolling direction of the wheel, to the shocks, as well as a memory for the identification code, and a transmitter which supplies signals with the identification code, the rolling direction and the occurrence of a shock on a wheel to a receiver which, based on the supplied rolling direction information, distinguishes identification codes pertaining to wheels on the left-hand or right-hand side of the vehicle from shocks which occur on the left-hand or right-hand side of the vehicle, measures the time interval elapsing between shock signals on one side of the vehicle, multiplies this time interval by the velocity of the vehicle measured within the same time interval.
