Abstract: A vehicle data acquisition system and method are provided for the analysis of vehicle conditions. A vehicle-external communication device, a vehicle-internal communication device, a vehicle-external computer and a vehicle-external databank are utilized. For providing an informative vehicle data acquisition system, on the basis of the data in the vehicle-external databank, the vehicle-external computer identifies those vehicles which have a first characteristic profile. The vehicle-external computer queries vehicle data from the identified vehicles by way of the vehicle-external and the vehicle-internal communication devices, and the vehicle-external computer evaluates the queried and received vehicle data for the analysis of vehicles having the first characteristic profile.

Abstract: In the case of a method of communicating between a motor vehicle and a diagnostic unit, a wireless communication connection is established between the motor vehicle and the diagnostic unit after an authorization of the diagnostic unit has been checked. The diagnostic unit is connected with a vehicle key assigned to the motor vehicle, and the authorization of the diagnostic unit is checked by use of authorization data stored in the vehicle key. A diagnostic unit for implementing such a method has devices for connecting with a vehicle key assigned to the motor vehicle. The diagnostic unit is suitable for receiving authorization data from the vehicle key, for the indirect or direct wireless communication with the motor vehicle, and for proving its authorization with respect to the motor vehicle by way of the received authorization data.

Abstract: The invention relates to a method for wirelessly transmitting vehicle data, whereby vehicle data provided for data exportation is stored in a storage medium, and is read out and transmitted within the framework of a vehicle data acquisition. At the beginning of the journey, the vehicle data provided for the data exportation is stored in the storage medium or is made available for subsequent readout. At the end of the journey, changes and/or additions are carried out on the data stored in the memory and/or made available at the beginning of the journey.

Abstract: A testing device is disclosed for testing structural parts and functions of motor vehicles according to a test program having successive program stages. The testing device comprises a program switch for establishing circuit connections associated with the stages of the test program and for controlling a first indicator device for reproduction of the corresponding measurements. The program switch of the device further controls a second indicator device for reproduction of stored, rated measurements associated with the program stages so that a direct comparison of the rated and actual measurements can be quickly made.
