Abstract: A method for locating wheels of a motor vehicle. The vehicle including at least one central processing unit which includes a main ultra-wideband radio frequency transceiver and a plurality of wheel units, each including a secondary ultra-wideband radio frequency transceiver adapted for communicating with the main transceiver. The method includes at least one step of measuring the distance between the main transceiver and the secondary transceiver to be located, by analyzing the propagation time of an exchanged message, and a step of locating the wheel unit associated with the secondary transceiver to be located, on the basis of the distance measured in the measurement step.

Abstract: A method for communicating between a portable transmission device and an electronic control unit of a motor vehicle. The method includes transmission, by the transmission device, of a plurality of wake-up signals over a plurality of consecutive time intervals referred to as “reference” time intervals. The duration of each reference time interval being equal to the duration of a supply period and each reference time interval being divided into a series of consecutive time slots. At least one wake-up signal of the plurality of wake-up signals being transmitted in each reference time interval, in a time slot that is different from the time slots of the other wake-up signals of the plurality of wake-up signals, and such that the sum of the transmission time intervals of each of the wake-up signals of the plurality of wake-up signals is at least equal to the supply period.
