Abstract: A method for adapting the strategy for acquiring measurements of the radial acceleration of the wheel sensors of a tire pressure monitoring system of a motor vehicle during phases in which the vehicle is stationary, in which the wheel sensors periodically measure parameters pertaining to the tires of the corresponding wheels, namely at least pressure, temperature and acceleration parameters. The method includes switching the radial acceleration measurement acquisition strategy of a wheel sensor during the “non-running” phases of the vehicle, between at least two state-of-activity modes, switching from a so-called “sleep” acquisition mode to a so-called “awake” acquisition mode when a pressure event is detected by the tire pressure monitoring system of the motor vehicle, the radial acceleration then being measured according to a period of significantly longer duration in “sleep” mode than in “awake” mode.

Abstract: The aim of the invention is to determine the minimum costs (MIN_KOST) from a starting location (STO) to a destination (ZIO), in order to plan a route on a map (MAP). To achieve this, starting nodes (STK) are determined in accordance with the starting location (STO). Different categories of starting node costs (STK_KOST) from the starting nodes (STK) to at least one predetermined map marker are assigned to the starting nodes (STK). At least the predetermined map marker(s) and the corresponding starting node costs (STK_KOST) of the different categories are determined in accordance with the starting nodes (STK). Destination nodes (ZIK) are determined in accordance with the destination (ZIO). Different categories of destination node costs (ZIK_KOST) from the destination nodes (ZIK) to at least the predetermined map marker are assigned to the destination nodes.
