Car driver's route information system with memory - uses test and comparison circuit fed with route measured values, car diagnostic values and signals for triggering stored information

摘要

The information system contains data pertaining to the vehicle condition, the travelled route, and general conditions in dependence on the already travelled distances, the vehicle condition and time. The system has an appropriate memory for the transmitted data. The measured values from appropriate devices are fed into a testing and comparison circuit which is in interacting relationship to a processor with a control device. The measured values may concern the travelled millage and/or time and/or vehicle and engine diagnostic data. Radio and telephone information and pulses may be included. Under the processor control the stored data are tripped acoustically and/or optically as a preprogrammed markings. A suitable device is in the form of an adaptor to a commercial cassette recorder, which contains the testing and comparison circuit and possibly the processor and additional memories.
