Abstract: A method for updating an operating function of a sensor, which has a memory that has a boot memory area for storing a boot function and an operating memory area for storing an operating function. The method has the following steps: execution of the boot function; checking whether an update for the operating function of the sensor needs to be performed; if an update for the operating function of the sensor does need to be performed, performing a plausibility check; if the plausibility check was successful, updating the operating function of the sensor such that data for an up-to-date operating function are received from an external unit and the data are written to the operating memory area. The reception of the data and the writing of the data to the operating memory area take place in parallel.

Abstract: In a method for determining identifiers of wheel units and positions relative to the vehicle of the wheels on which the wheel units are fitted, the vehicle is equipped with a speed sensor for each wheel and elements for transmitting at a predetermined angular position of the corresponding wheel about its axis a message including the identifier of the wheel unit. A central processing unit receives the message and information from the speed sensors. The method includes a) counting, for each identifier, of a number “nt” of receptions of the identifier, b) statistical processing of the numbers “nt” to determine candidate identifiers of a wheel unit of the vehicle, until the number of candidate identifiers at least equals the number of wheels, and c) determining that a candidate identifier is the identifier of a wheel unit if the candidate identifier meets a predetermined criterion.
