Data acquisition system for vehicles

摘要

In a data acquisition system for vehicles, the acquisition device (2) installed in the vehicle is to be capable of being matched to the vehicle (1) and the engine as easily as possible and at the same time it is to be possible to test the signal generator terminals (19, 33). In a computer (5), a test cartridge (40) is loaded with the known vehicle data. The test cartridge (40) or the acquisition device (2) contain a test program memory (52) and different test routines, such as matching of the constant W for vehicles and of the engine speed etc, can be called up in this program memory (52) via a switching and monitoring mechanism (42). Also, all the signal generator terminals can be tested for operativeness. <IMAGE>
