ARRANGEMENT FOR PROGRAMMING AN EMBEDDED SYSTEM IN A VEHICLE

摘要

A system for programming an embedded system disposed in a vehicle is set forth. The programming system comprises an external programmer and a principal control unit fixed in the vehicle. The principal control unit is coupled for communicating with the embedded system and the external programmer, and responds to communications received from the external programmer to direct the embedded system to enter a programming mode. While in the programming mode, the embedded system is programmed by the principal control unit in response to communications from the external programmer. In one example, programming is described in the context of a telematics system in which the principal control unit is a telematics control unit that oversees the operation of a plurality of embedded systems within the telematics system.
