System for simultaneously brushing multiple vehicle-mounted chips

Abstract

The invention discloses a system for simultaneously brushing multiple vehicle-mounted chips. The system comprises a main control unit, a brushing and writing unit and a wiring harness interface unit, wherein the brushing and writing unit comprises at least two brushing and writing modules, each brushing and writing module is respectively connected with the wiring harness interface unit, information interaction is executed among the main control unit and said at least two brushing and writing modules through a high speed bus, if a storage device plugged in an USB (Universal Serial Bus) interface is detected by the main control unit, demarcated documents or demarcated package documents in the storage device are selected by the main control unit, and then selected demarcated documents or demarcated package documents are transmitted to each brushing and writing module. The system can be clustered and expanded, and the amount of the brushing and writing modules is customized according to client's requirements, thus the system is excellent in expandability, and simple and quick in operation; the vehicle-mounted chip can be automatically identified and multiple vehicle-mounted chips can be brushed and written at the same time, thus the brushing and writing efficiency is increased, the fault of the manual operation is reduced, and the system can be totally used for in batch brushing and writing in after-sale services, automobile companies and engine factories.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a multi-swipe system for batch flashing of vehicle-mounted chips, especially ECUs or TCUs. Background technique [0002] The data flashing of the vehicle ECU or TCU is a necessary link in the vehicle production line. [0003] ECU or TCU flashing has always been the most important link in after-sales service. Due to the relatively low technical level of repair workers in the aftermarket, the reliability and efficiency of flashing cannot be guaranteed. [0004] At present, ECU flashing equipment is usually developed and provided by ECU manufacturers, and the communication protocols (such as K_Line, CAN) and interface types followed by each manufacturer are different. In the case of a mixed production line, the same production line needs to be equipped with various types of ECU writing equipment, and the independent writing equipment makes the production work compli...

AI Technical Summary

Problems solved by technology

[0006] In addition, engine factories, OEMs, and after-sales services all need to flash a large number of ECMs, and each ECM usually takes about 5 minutes to flash, while traditional flashing tools can only flash one-to-one, which is inefficient and wastes a lot of labor

At the same time, considering the development cost and flashing reliability, it is impossible to use the traditional multi-communication module equipment and write special computer software for development.

[0007] Due to the above-mentioned problems in the actual situation, and there is no product or method to solve these problems, it is really necessary to make improvements
