Abstract

In an early warning system for the preventive detection and correction of defects in vehicles (1) vehicle-specific data are transmitted without caching by a single transfer process in real time and automatically evaluated in a central computer (4) and an alarm message to a technical center (5 ) forwarded.

Description

The The invention relates to an early warning system for preventive Detection and correction of defects in at least one Vehicle according to the closer defined in the preamble of claim 1 Art.

Of the The use of remote diagnostic systems is particularly important in modern motor vehicles, the with many electronic sensors and control units for measurement or control certain state parameters are known. It may be, for example, to facilities for engine and / or Transmission control, anti-lock braking systems, electronic chassis control devices or something similar.

From the DE 19933334 A1 a remote diagnosis system is known, which consists of a local diagnostic unit on the vehicle and a stationary remote diagnosis unit. To communicate the two diagnostic units, a wireless data connection is established via communication interfaces, at least temporarily. Via the user interface of the remote diagnosis unit, vehicle data can be viewed and evaluated by an operator. In addition, via the user interface of the remote diagnosis unit, it is also possible to send control commands for changing certain state parameters to the control units of the vehicle and to execute them there. Such control allows direct access to the vehicle's condition parameters so that vehicle operation can be largely controlled from the remote diagnostic unit. For the preparation of the diagnostic process, however, an intervention on the vehicle by a trained trained operator is required.

From the DE 10329520 A1 a remote diagnosis unit is known, which is designed as a portable processor system. This creates a mobile services center that can make the data exchange from and to the various functional units of a vehicle.

at known from the prior art early warning systems is only after the occurrence of at least one malfunction on this reacts and determines the damage to the vehicle or eliminated. Furthermore the diagnostic operation must be performed by an intervention of an operator to get prepared.

Of the present invention is based on the object, an early warning system to represent what potential damage occurred before it occurred can detect and damage caused by interference with the vehicle can be avoided, the diagnostic process automatically is executed and transmit the diagnostic data in authenticity become.

The The object underlying the invention is by a, also the characterizing features of the main claim exhibiting, generic Early warning system for preventive detection and correction from defects in vehicles solved.

at the early warning system according to the invention becomes a data connection by automatic calls of a central computer set up between a central computer and at least one vehicle. For example, these calls may be for one in the central computer programmed time sequence are executed. Preferably the connection to the data transmission is made, if the vehicle is in operation. The to be transferred Data is sent via an interface without local caching through a one-time transfer process in real time transmitted to the central computer. A central computer provides automatic connection to the diagnostic memories the integrated electronics in the vehicles and networked thus an entire vehicle fleet. The central computer evaluates the received data and stores them in a database. When exceeding preprogrammed limits is over the central computer an alarm message issued, which to a technical center is forwarded. An operator of technical center can then physical interventions on the vehicles trigger malfunction of, for example, vehicle control units or components can be prevented. Furthermore, over the technical center driving program data modified and telemetric be flashed into the appropriate control unit in the vehicle. This leads to a preventive avoidance of damage in the vehicle fleet due to errors or damage in the vehicle fleet Single vehicle. Are several vehicles with the invention Early warning system equipped, the vehicles through the automatic calls of the central computer to each other networked, creating a vehicle fleet whose vehicle data can be evaluated by the central computer. Farther can by the solution according to the invention several vehicle fleets and several central computers networked with each other be an evaluation of the data of each networked central computer via another server can be done, which in addition to the preventive service For a vehicle fleet also the statistical detection and tracking of damage patterns across fleets he follows. This will be preventive interventions in the vehicles allows before first indications of the vehicle electronics can report this.

in the The following is the invention with reference to the figures shown in the figures Embodiments explained in more detail.

It demonstrate:

1 an early warning system according to the present invention for a vehicle fleet and

2 an early warning system according to the present invention for several interconnected vehicle fleets.

1 shows an inventive early warning system for a vehicle fleet 6 , By automatic calls from a central computer 4 is a data connection between the central computer 4 and a vehicle 1 built up. The diagnostic data is transmitted via an interface 2 without local caching by a mobile phone, pocket PC, PDA, smartphone or comparable handhelds 3 in real time to the central computer 4 transmitted. The central computer 4 evaluates the received data and sends an alarm message to a technical center if pre-programmed limit values are exceeded 5 , From the technical center 5 An operator may experience physical interference with the vehicle 1 trigger and thereby prevent malfunctions. Furthermore, the technical center 5 Modify driving program data and telemetrically into the control unit of the vehicle 1 transfer.

2 shows an inventive early warning system, which is networked by another level and thus several vehicle fleets 6 and several central computers 4 which are operated, for example, in different countries. The evaluation of data during an alarm message of the individual networked central computer 4 takes place via a central server 7 , which in addition to the preventive service for a vehicle fleet 6 Statistical detection and tracking of damage patterns across fleets is also possible. This is preventive intervention in the vehicle 1 possible before the first indications in the vehicle electronics are detected. As a result, damage events that occur in one vehicle fleet can already be anticipated in other vehicle fleets 6 be avoided.
