Abstract

A method and a system for exchanging data between at least one vehicle-mounted control device and a portable hand-held device, for example in the form of a key in which software for transmission to the at least one vehicle-mounted control device is stored.

Claims

1. In a system for the exchange of data between a vehicle-mounted control device and a portable device having software for transmission to the vehicle-mounted control device stored therein, the improvement wherein the portable device has a diagnostic unit for identification of software in the vehicle-mounted control device.

2. The system according to claim 1, wherein said portable device is a key and the vehicle-mounted control device communicates with the key via an ignition lock of the vehicle when the key is inserted in the ignition lock.

3. The system according to claim 2, which comprises a transponder coil in the ignition lock for wireless communication with said key and for supplying power to said key.

4. The system according to claim 1, wherein the portable device has a loading unit for transmission of the software stored in the portable device to the vehicle-mounted control device.

5. A method for exchanging data between control devices for a vehicle, the method which comprises:

reading a software version of at least one vehicle-mounted control device with a portable hand-held device;

comparing the software version of the vehicle-mounted control device with a software version stored in the hand-held device, by means of a diagnostic unit of the portable hand-held device; and

if the software version of the vehicle-mounted control device is older than the software version stored in the hand-held device, transmitting the software stored in the hand-held device to the at least one vehicle-mounted control device.
