Abstract

The invention relates to the technical field of automobile control methods, and particularly relates to a vehicle door minimum closing speed test device and a test method. The device comprises a speed acquisition module located near a vehicle door edge closing position and used for acquiring the speed when a vehicle door is closed, a torque applying module which is used for applying a torque to the vehicle door to push the vehicle door to close, a vehicle door locking sensing module which is used for sensing whether a vehicle door is locked or not, and a central control module which is used for controlling the torque applying module by acquiring signals of the speed acquisition module and the vehicle door locking sensing module, wherein the central control module is in signal connection with the speed acquisition module, the torque applying module and the vehicle door locking sensing module. The door closing torque of the vehicle door is controlled and adjusted through the central processing unit, the minimum torque for closing the vehicle door can be obtained after repeated tests by repeatedly adjusting the door closing torque of the vehicle door and gradually decreasing or increasing the door closing torque, and therefore the minimum speed for locking the vehicle door can be rapidly obtained; and the device can be applied to the design of a device for automatically locking the vehicle door, and has a high popularization value.

Description

technical field [0001] The invention relates to the technical field of automobile control methods, in particular to a test device and a test method for the minimum closing speed of a car door. Background technique [0002] With the rapid development of automobiles, people's requirements for automobiles are getting higher and higher, and the minimum closing speed of automobile doors as an important subjective experience has been paid more and more attention to. Operation, because the manual operation is difficult to control, so the measurement accuracy is very poor, and the test results cannot be obtained effectively and accurately. [0003] A paper titled "Research on Closing Speed ​​of Automobile Doors and Quantitative Force Application" introduced a specially designed force application device, which keeps the force applied to the door constant, improves the accuracy of the door closing speed test, and reduces testing labor. Strength, improve work efficiency. When the for...
