Central ECU development test system

Abstract

The invention discloses a central ECU development test system. The system comprises a plurality of upper computers, a plurality of lower computers in one-to-one correspondence with the upper computers, a switch, a plurality of ECUs arranged in a centralized manner and a programmable power supply, the plurality of upper computers are respectively connected with the corresponding lower computers, the plurality of lower computers are connected with the switch, the plurality of ECUs are respectively connected with the switch through wiring harnesses, a communication port of the programmable powersupply is connected with the plurality of upper computers, and a power supply port of the programmable power supply is connected with power supply ports of the plurality of ECUs. According to the invention, the plurality of ECUs are arranged in a centralized manner; unified power supply is carried out by the programmable power supply; a user can enable the upper computers to communicate with the target ECU through the corresponding lower computers and the switch according to needs, so that the ECU is developed and tested; the wiring harnesses are few, unified standard management is facilitated, the utilization rate of the ECUs is high, the cost is low, and meanwhile, the system has the advantages of being easy to operate and not prone to making mistakes.

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
