Abstract

The invention discloses a programming wire harness for the electronic control units of diesel engines of multiple systems, relates to an electronic control unit programming and aims to solve the technical problem that an existing wire harness can only be programmed in a one-to-one mode. The programming wire harness comprises a main wire harness and a sub wire harness which are connected with eachother; the main wire harness is provided with a power source connector, a power source switch, an ignition switch and a communication interface which is connected with an ECU; the sub wire harness comprises a plurality of sub wire harnesses which are connected in parallel; each branch wire harness is connected with the power source connector, the power source switch, the ignition switch and the communication interface through the main wire harness; and each branch wire harness is provided with a system interface connected with a corresponding electric control system. According to the programming wire harness for the electronic control units of the diesel engines of multiple systems of the invention, the main wire harness corresponding to the ECU and the branches wire harnesses corresponding to the different electronic control systems are adopted, and therefore, the requirement that the ECU is programmed by the multiple electronic control systems can be met; and when diesel engines withdifferent purposes or for different electronic control systems are subjected to mixed wire production, the programming wire harness does not need to be replaced frequently.

Description

technical field [0001] The invention relates to programming of electronic control units, more specifically, it relates to a wiring harness for programming of electronic control units of diesel engines for multiple systems. Background technique [0002] The electronic control unit (ECU) is the comprehensive control device of the engine. Its function is to calculate, process, and judge various information input by the various sensors of the engine according to the program stored in itself, and then output instructions to control the action of the relevant actuators, so as to achieve the purpose of fast, accurate, and automatic control of the engine. In order to make the engines for different purposes play their roles, it is necessary to program different software programs for the ECU, so as to meet the requirements of precise control. When programming the ECU program, it is necessary to use the programming harness to connect the programming tool to realize the programming of ...
