Abstract

The present invention provides an inexpensive, automobile test diagnostic system which is capable of processing data from multiple high speed data channels. The vehicle test diagnostic system include an integrated computer for providing access to a technical database comprised of stored information records, with migration capacity between related records, and further to provide selective access to particular portions of information within the database, the integrated computer including a user interface responsive to operation by a user to provide commands, and a microprocessor responsive to commands entered through the user interface to access the information; and at least one instrumentation module electrically coupled to the integrated computer, the instrumentation module being responsive to commands entered through the user interface.

Claims

1. A vehicle test diagnostic system to provide information to maintain and repair equipment or provide services, comprising:

an integrated control means for providing access to a technical database comprised of stored information records, with migration capacity between related records, and further to provide selective access to particular portions of information within the database, the integrated control means including a user interface responsive to operation by a user to provide commands, and a processing means responsive to commands entered through the user interface to access information;

at least one instrumentation module electrically coupled to the integrated control means and a system of the vehicle under test, the instrumentation module being responsive to commands entered through the user interface;

a vehicle communication link module electrically coupled to the integrated control means and an on-board computer of the system of the vehicle under test, wherein the vehicle communication link module is further coupled in parallel to the at least one instrumentation module.

2. The vehicle test diagnostic system recited in claim 1 wherein the means for electrically coupling the integrated control means to the at least one instrumentation module is a IEEE 1394 bus.

3. The vehicle test diagnostic system recited in claim 1 wherein the integrated control means further includes an integrated controller memory means, wherein the technical database is transferred to the integrated controller memory means from a technical database memory storage means, the data transfer occurring during a time period when the technical database storage means is electrically coupled to the integrated controller memory means.

4. The vehicle test diagnostic system recited in claim 3 wherein the technical database memory storage means is removable.

5. The vehicle test diagnostic system recited in claim 3 wherein the technical database memory storage means is a CD ROM.

6. The vehicle test diagnostic system recited in claim 1 wherein the integrated control means further includes an integrated controller memory means and further wherein an applications program for controlling the vehicle test diagnostic system is stored in the integrated controller memory means.

7. The vehicle test diagnostic system recited in claim 1 further comprising a docking station means electrically coupled to the integrated control means.

8. The vehicle test diagnostic system recited in claim 7 wherein the docking station means further includes a technical database memory storage means.

9. The vehicle test diagnostic system recited in claim 7 wherein the docking station means further includes a means for communicating with a means for storing test vehicle data.

10. The vehicle test diagnostic system recited in claim 7 wherein the docking station means further including a power supply means.

11. The vehicle diagnostic system recited in claim 1 wherein the at least one vehicle instrumentation module is electrically coupled to a battery of a vehicle currently under test.

12. The vehicle diagnostic system recited in claim 1 wherein the at least one vehicle instrumentation module includes a vehicle instrumentation power supply.
