Complete vehicle off-line configuration system and configuration method thereof

Abstract

The invention discloses an end-of-line configuration system and a configuration method for a finished vehicle. The system comprises a vehicle type configuration database, end-of-line equipment which is applicable to a controller area network (CAN) platform, and one or more electric control units in the finished vehicle, wherein the vehicle type configuration database is used for storing and querying finished vehicle codes and the finished vehicle configuration information, corresponding to each finished vehicle code, of the vehicle type; the end-of-line equipment is used for acquiring the finished vehicle configuration information from the vehicle type configuration database, coding the finished vehicle configuration information and writing the finished vehicle configuration information into the electric control units; the end-of-line equipment is connected with the vehicle type configuration database and the electric control units through CAN communication; and the electric control units are used for acquiring configuration information codes from the end-of-line equipment. The invention has the advantages that: the structure of the vehicle is not changed; and the configuration ofthe finished vehicle is adjusted by flashing the configuration codes, so the quantity of the electric control units is effectively reduced, and the electric control units can be applied to vehicles of different configurations.

Description

technical field [0001] The invention relates to the field of vehicle electrical control devices and their layout, in particular to a vehicle off-line configuration system and a configuration method thereof. Background technique [0002] With the rapid development of automotive electronics technology, the functional complexity of the vehicle is increasing day by day, and the safety. The requirements for environmental protection and energy saving are becoming increasingly stringent, the needs of customers with comfort, flexibility and individuality vary widely, the globalization of market competition has shortened the development cycle, and a large number of electronic controllers are widely used in automobiles. [0003] When the car is assembled, the controller needs to be configured according to the target market requirements, local regulatory requirements, and vehicle configuration requirements. Such as engine controller, light controller, instrument controller, engine...

[0005] The patent with publication date of June 11, 2008 and publication number CN101197022A discloses a vehicle configuration method for a vehicle diagnostic instrument. The corresponding controller of the vehicle is configured through the feature key, and the updated controller configuration information is written into the vehicle. Among the corresponding controllers, however, the invention is implemented using a diagnostic instrument, which is only suitable for vehicle diagnostic services. The diagnostic instrument can only be configured with a small part, and can only be used to simply distinguish the software of the ECU, and cannot be used for the entire production line.
