Abstract
An allocation method combines two tire pressure monitoring systems in motor vehicles being equipped with pressure measuring modules. Each pressure measuring module records a value responsive to the tire inflation pressure and sends the latter to a receiving unit connected to an evaluating device together with an individual identification code (IDx) allocated to the respective pressure measuring module. Signals about the rotational speed of each one wheel being sensed by wheel rotational speed sensors are transmitted to the evaluating device, and since the installation positions y of the wheels at the vehicle are known to the evaluating device, the wheels at the vehicle are known, and the allocation method is performed by taking into consideration established probability values W_IDx_y, with the probability values W_IDx_y describing a frequency distribution which indicates how often pressure measuring modules with the identification codes IDx are detected as pertaining to the installation positions y.
