METHOD FOR PROVIDING WIRELESS VEHICLE ACCESS

摘要

A method for providing wireless vehicle access, wherein a connection is set up between an ID signal generator which is assigned to the motor vehicle and a wireless communication device. A first identification code which is stored in the ID signal generator is transmitted to the communication device, and a connection is set up between the wireless communication device and a service provider by means of a public communication network. The identification code is sent to the service provider together with a second identification code which identifies the wireless communication device. A multi-part authorization message is generated by the service provider, and parts of the authorization message are sent to the wireless communication device while parts of the authorization message are also transmitted to a control device in the motor vehicle. Access authorization of the communication device is checked on the basis of the part of the authorization message from the motor vehicle and the part from the communication device, by means of a connection between the wireless communication device and the control device of the motor vehicle.
