DIAGNOSTIC UNIT AND METHOD

摘要

A diagnostic unit is coupled to at least one vehicle control subsystem. The vehicle control subsystem includes one or more of a brake control unit, an engine control unit, and a transmission control unit to provide vehicle data. The diagnostic unit generates diagnostic log information based on the vehicle data and communicates the diagnostic log information to a remote computing device, which hosts a reverse auction to identify at least one vendor that can provide vehicle service based on the diagnostic log information. After identifying the vendor, the diagnostic unit generates and presents service information representing the identified vendor to a vehicle operator via an input/output interface in the vehicle. The input/output interface can accept vehicle data, configuration data, and diagnostic data from the vehicle and the vehicle operator.

1. A method to operate a diagnostic unit installed onboard a medium or heavy duty vehicle, comprising:
powering the diagnostic unit with onboard vehicle electric power; receiving parameters that control the receipt of vehicle data; receiving the vehicle data from at least one of a brake control unit, an engine control unit, and a transmission control unit based on the received parameters; generating a diagnostic log file from at least some of the vehicle data; communicating the diagnostic log file to a remote computing device arranged to host a reverse auction that identifies at least one vendor capable of providing vehicle service based on the communicated vehicle data; receiving service information identifying the at least one vendor capable of providing the vehicle service; and presenting service information representing the at least one vendor capable of providing vehicle service through an output device of the diagnostic unit.
