Central ecu development test system

Abstract

A central ECU development and testing system, comprising a plurality of upper computers and a plurality of lower computers corresponding to the upper computers one by one, a switch, a plurality of ECUs arranged in a centralized manner, and a program-controlled power supply, and the plurality of upper computers are respectively connected to the corresponding lower computers. computer connection, the plurality of lower computers are connected to the switch, the plurality of ECUs are respectively connected to the switch through wire harnesses, the communication ports of the program-controlled power supply are connected to the plurality of upper computers, and the power supply of the program-controlled power supply The ports are connected to the power supply ports of the multiple ECUs. In the present invention, a plurality of ECUs are centrally arranged, and the program-controlled power supply is uniformly powered, and the user can make the upper computer communicate with the target ECU through the corresponding lower computer and switchboard according to the needs, so as to develop and test the ECU. There are fewer wire harnesses, which is convenient for unified and standardized management, and the utilization rate of ECU is high, and the cost is low. At the same time, it has the advantages of simple operation and less error-prone.

Description

technical field [0001] The invention belongs to the technical field of ECU development and testing, in particular to a central ECU development and testing system. Background technique [0002] During the development and testing process of automotive electronic control unit ECU, a large number of development and testing personnel are required, and each technician usually needs to develop and test multiple ECUs at the same time, which leads to a large number of ECUs, lower computer VCI (Vehicle Connection Interface) and wiring harnesses are piled up in the office area, equipment management is chaotic, and circuit safety accidents are prone to occur. [0003] Most of the existing ECU development and test benches are single individual benches, which are placed on the technician’s workbench, and there are many wiring harnesses, which is not conducive to unified and standardized management. Each bench may be equipped with the same number of ECUs. The configuration utilization rat...

[0002] During the development and testing process of automotive electronic control unit ECU, a large number of development and testing personnel are required, and each technician usually needs to develop and test multiple ECUs at the same time, which leads to a large number of ECUs, lower computer VCI (Vehicle Connection Interface) and wiring harnesses are piled up in the office area, equipment management is chaotic, and circuit safety accidents are prone to occur

[0003] Most of the existing ECU development and test benches are single individual benches, which are placed on the technician’s workbench, and there are many wiring harnesses, which is not conducive to unified and standardized management. Each bench may be equipped with the same number of ECUs. The configuration utilization rate is low, the cost is high, or multiple ECUs are concentrated on the surrounding shelves. When testing different ECUs, technicians need to go to the shelf to manually switch equipment. The operation is complicated and error-prone
