摘要:
A modular electronic system for vehicles employing a microprocessor to facilitate the implementation of additional vehicular features embodied in electronic accessory modules. The system includes a housing with separate mounting areas for receiving at least one of a plurality of plug-in electrical modules and one of a plurality of display boards for displaying information relating to associated modules.
摘要:
An electrical system providing automatic calibration of a vehicle compass for abrupt and significant changes in vehicle magnetism. The system includes a magnetic field sensor providing signal information representing the magnetic field sensed within the vehicle. Coupled to the sensor is an electrical circuit for processing the signal information from the sensor to determine if a shift in vehicle magnetism has occurred and for calculating compensation signal information to provide a corrected heading display.
