Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] The invention provides a method for flashing and writing multiple trip computers at the same time.

[0057] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the method for flashing multiple trip computers at the same time according to the present invention.

[0058] In this embodiment, the method includes:

[0059] Step S100, start the function of flashing the flashing program of the trip computer ECU according to the instruction triggered by the user.

[0060]In this embodiment, in order to ensure that this implementation can be implemented normally, before implementing this embodiment, a preset software needs to be established first. The preset software can be written in a computer language, such as C language, C++, Java, etc. Instructions are written in computer langu...

Abstract

The invention discloses a method for simultaneously writing of a plurality of electronic control units (ECU). The method comprises: according to an instruction triggered by a user, a function of writing writing programs of ECUs is started; connection with ECUs of all vehicles is carried out by an interface unit; vehicle type codes and / or vehicle identification numbers (VIN) of all vehicles are obtained; according to the vehicle type codes and / or vehicle identification numbers (VIN), the corresponding writing programs are extracted and the extracted writing programs are written into the corresponding ECUs; and parameters after writing are written into the corresponding ECUs. In addition, the invention also discloses a device for simultaneously writing a plurality of electronic control units. According to the invention, multiple ECUs can be written simultaneously and the writing efficiency increases.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for simultaneously flashing and writing multiple driving computers. Background technique [0002] The car driving computer (ECU) is generally used to precisely control the fuel consumption of the engine, optimize the economy of use, and report the fuel consumption in real time. Therefore, ECU parameter calibration and diagnostic testing are required before the car goes off the assembly line to ensure the normal performance of the engine, especially the parameter configuration of the electronic control system, so that the engine is in the best state. However, when the car leaves the factory, the performance of the ECU is not fully utilized. Therefore, how to improve the power and reduce the fuel consumption of the car by flashing the ECU is an urgent problem for today's cars. [0003] At present, ECU flashing equipment is usually developed and provided by ...
