Embodiment Construction

[0021] Preferably, the method of the present invention ends with obtaining the identification code, as long as the frequency assigned to an ABS sensor by a certain identification code exceeds the frequency assigned to other ABS sensors by the same identification code by a predetermined value, the identification code corresponding to the position of the ABS sensor is just deleted. stored in memory. This predetermined value may include some empirical values. This predetermined value is a predetermined extreme value of the ratio of the frequency assigned to an ABS sensor by an identification code to the frequency assigned to other ABS sensors by the same identification code. In addition, a criterion can also be set to determine whether to store an identification code with a clearly advantageous assignment corresponding to the corresponding ABS sensor, that is, it exceeds the clearly advantageous assignment of an identification code for the corresponding ABS sensor. The limit val...

Abstract

Allocates identifiers of units of a tire pressure monitoring system to the positions of ABS-sensors which are each assigned to the wheels of the vehicle. The identifiers are contained in signals that are emitted by the units. Each unit, which is called a wheel electronic, has a pressure sensor, which is sensitive to the tire pressure of the wheel, a motion sensor, which provides information on the rotation speed of the wheel, a memory with the individual identifier of the wheel stored therein, and a transmitter, which transmits signals only containing information on the rotation speed of the respective wheel, to a receiver. An evaluation device receives the transmitted identifier and compares the information on the rotation speed of the wheel transmitted along with the identifier, with rotation speed information, which were acquired by the ABS sensors for the same time span and transferred to the evaluation device.

Description

technical field [0001] The invention relates to a method for assigning an identification code of a wheel electronics device of a tire pressure monitoring system of an automobile to the position of an ABS sensor of an automobile. Background technique [0002] The invention relates to a method for assigning an identification code to the position of an ABS sensor, said identification code being included in the signal emitted by the tire pressure monitoring system unit of a motor vehicle. In the following text, the units mounted on the wheels of automobiles are referred to as wheel electronics. Each wheel electronic device includes a pressure sensor, which can detect the pressure of the wheel tire; a dynamic sensor, especially an acceleration sensor, used to provide wheel speed information; a memory, stored in the memory The identification code of the wheel electronic device; the transmitter that transmits a signal to the receiver. The transmitted signal not only includes each ...
