Method of the transmission of data
First Claim
1. A method for the transmission of data between a transponder (16) which is incorporated in a vehicle (12) and an inquiry station (20), said transponder being supplied by its own energy storage (44) which is charged by a charging station (18) via wireless energy transmission, characterized by the following steps:
- said transponder (16) first passes the transmission range (22) of said charging station (18), whereby said energy storage (44) is being loaded, said transponder (16) reaches the transmission range (24) of said inquiry station (20), said inquiry station (20) sends on a first frequency a request signal which is received by said transponder (16), said transponder (16) sends the requested data on a second frequency.

Abstract
The invention relates to a method for transmitting data between a transponder which is incorporated in a vehicle and an inquiry station, said transponder being applied by an energy storage of its own which is charged by a charging station via wireless energy transmission. In this method the transponder first passes the transmission range of the charging station whereby the energy storage is being charged, then the transponder reaches the transmission range of the inquiry station causing the inquiry station to send a request signal on a first frequency which is received by the transponder. The transponder then sends the requested data on a second frequency. Since the vehicle passes the transmission range of the inquiry station first, the energy storage of the transponder can be charged during the whole time in which the vehicle resides within this transmission range. After the charge of the energy storage, the transponder can send on a second frequency, which may be higher in order to cope with a larger amount of data, when it resides within the transmission range of the inquiry station with no need for the term of transmission to be reduced on account of charging.
