Automated detection and real vehicle simulation test method for the motor controller of the towing platform

Abstract

The invention discloses an automatic detection method for a motor controller of a towing platform and a real vehicle simulation test method, including a VCU (vehicle controller), a test tool JIG, a 24V stabilized power supply, a motor towing platform (MgSet), and a high-voltage power distribution device, and two sets of MCU (motor controller) to be tested. The problem solved by the invention is how to make the whole vehicle controller simulate the working condition of the real vehicle, and how to automatically send and control the motor controller with instructions. The invention realizes automatic detection of the motor controller and simulates the working conditions of the real vehicle through the control of the whole vehicle controller. There is no human misoperation, the detection coverage is wide, and the production efficiency and product quality are greatly improved.

Description

Technical field: [0001] The invention relates to an automatic detection method for a motor controller of a towing platform and a real vehicle simulation test method. Background technique: [0002] For new energy vehicles, the power system is the core of the entire vehicle. The reliability of the power system determines the reliability of the vehicle, and in the power system, the reliability of the motor controller is the key. [0003] At this stage, most manufacturers’ quality control of motor controllers is limited to hardware quality, as well as testing the rated and peak output current of the motor controller, and rarely involves testing under actual vehicle conditions. At the same time, such testing methods , Relevant personnel are required to control the test status of the product on site, which is a waste of human resources for the enterprise and invisibly increases the risk of human misoperation. The motor controller serves the vehicle, and the actual operating cond...

Problems solved by technology

[0003] At this stage, most manufacturers’ quality control of motor controllers is limited to hardware quality, as well as testing the rated and peak output current of the motor controller, and rarely involves testing under actual vehicle conditions. At the same time, such testing methods , Relevant personnel are required to control the test status of the product on site, which is a waste of human resources for the enterprise and invisibly increases the risk of human misoperation

The motor controller serves the vehicle, and the actual operating conditions of the vehicle are complex. The above-mentioned test method covers a narrow range and cannot expose as many hidden fault states of the motor controller as possible.
