1. Device for performing remote diagnostics on vehicles, having:
- a mobile unit (M) with;
an adapter (1) which can be connected to a vehicle on which diagnostics are to be performed and which reads out operational data and fault data of the vehicle, the adapter (1) having a transmitter device or a transceiver device via which the stored data can be transmitted to a receiver or data can be received from an external transmitter;
a mobile unit (M) with a portable diagnostics device (2) with an input/output unit (2a;
2a1, 2a2, 2a3, 2a4) and a portable small computer (2b) which each have a transceiver device for the cordless exchange of data with one another;
a base station (3) for receiving data from the adapter (1) and the mobile unit (M) and transmitting data to and receiving data from a network input node (4); and
a fixed unit (S) with the network input node (4), a personal computer (5) with a display device (6) and an input/output device (7;
7a, 7b), and a storage device (8) for storing information relating to a vehicle repair.

Abstract
In summary, the invention discloses a device and a method for performing remote diagnostics on vehicles, in particular on electrical, mechanical and mechatronic components of vehicles, with which, even in the case of complicated vehicle defects and/or vehicle defects which are difficult to find, the service technician can find and recover the problem in a very short time, if necessary by means of real-time access to external databases and/or by involving a service centre so that the non-operational times in the event of a fault are minimized.

10. Method for performing remote diagnostics on vehicles, having the steps:
-
(1) reading out of vehicle and fault data from a vehicle storage device into an input/output unit (2a) of a mobile unit (M) in response to a voice input, (2) displaying of the read-out data on the input/output unit (2a) of the mobile unit (M), (3) if a fault which has occurred cannot be found and/or recovered by means of this data, accessing of information stored in a fixed unit (S) in response to a renewed voice input into the input/output unit (2a) of the mobile unit (M), selection of the required information in accordance with the data read out from the vehicle storage device, transmission of the required information to the mobile unit (M) and representation of the required information on the input/output unit (2a) of the mobile unit (M), and (4) execution of a repair using the represented, required information. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
(5) if the information stored in the fixed unit (S) does not contribute to the solution of the problem, and therefore a repair cannot be carried out, collection of images of a possibly defective vehicle area and of voice explanations relating to these images, and transmission of this data to the fixed unit (S) to be displayed and output by an input/output unit (6, 7) of the fixed unit (S) in order to permit analysis by a specialist, (6) collection of a repair instruction of the specialist via the input/output unit (6, 7) of the fixed unit (S) and transmission of this repair instruction to the mobile unit (M) and outputting of the repair instruction on the input/output device (2a) of the mobile unit (M), and (7) execution of the repair in accordance with the repair instruction which is output. -
12. Method according to claim 10, characterized in that the information which is accessed in response to a voice input comprises circuit diagrams, repair instructions, a description of problems which occur rarely and their recovery, etc.
-
13. Method according to claim 10, characterized in that if the represented, required information is, contrary to expectations, not sufficient for a repair, step (3) is executed again.
-
14. Method according to claim 10, characterized in that if the repair instruction of the specialist is not sufficient, steps (5) and (6 ) are repeated.
-
15. Method according to claim 10, having the further steps (0) before a step (1) monitoring of the vehicle function, detection of a fault which occurs and in response thereto automatic initiation of steps (1) and (3) by the mobile unit (M), the mobile unit (M) being built into the vehicle.
-
16. Method according to claim 11, characterized in that in the event of breakdown a driver initiates execution of steps (1), (5), (6) and (7).
-
17. Method according to claim 16, characterized in that the fixed unit (S) initiates the following if the specialist detects that a repair is not possible by the driver:
- agreement of a workshop appointment and transmission and display of this appointment and of the position/the route to the workshop on the input/output unit (2a) of the mobile unit (M) and, if the vehicle is no longer roadworthy, or can no longer be made roadworthy, provision of information to a breakdown service.
-
18. Method according to claim 15, characterized in that the fixed unit (S) initiates the following if the specialist detects that a repair is not possible by the driver:
