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 adjusting a clock on board a motor vehicle, said clock providing an actual time for functions of the vehicle, said vehicle being connected via wireless communication to a data server, said method comprising:
A device for adjusting a clock on board a motor vehicle for use with a server having wireless communication capability, said clock providing an actual time to vehicle functions, said device comprising:
