A method for adjusting a clock on board a motor vehicle, the clock providing an actual time for functions of the vehicle, the vehicle connected via wireless communication to a data server, the method including: the server transmitting a sequence of consecutive actual-time values, separated from one another by a fixed time interval; the vehicle receiving the actual-time values shifted by an unknown and variable time of flight between transmission and reception; for each received actual-time value: calculating a difference between an actual-time value received at a given instant and an actual-time value received at a previous instant; calculating a discrepancy between the calculated difference and the fixed time interval; calculating a cumulative disparity, consisting in summing the discrepancy calculated for a time value received at one instant and a time value received at the previous instant; determining the actual time for adjusting the on-board clock according to the disparity.

A method for managing authorization to access a shared vehicle, the vehicle having a memory dimensioned to simultaneously store a maximum number of reservations. The method includes obtaining a first reservation of a vehicle, searching, in a local representation of the memory of the vehicle, for an available location for storing the first reservation, and when there is no available location for storing the first reservation, selecting, from the reservations stored in the local representation of the vehicle's memory, a second reservation such that the start date of the second reservation is after the start date of the first reservation, storing the characteristics of the second reservation in a waiting list, replacing, in the local representation of the memory of the vehicle, the selected reservation with the first reservation, and transmitting, to the vehicle, a command to delete the second reservation, and a command to add the first reservation.
