Abstract

The invention provides an anti-clamping judgment method and system for a vehicle body closing system. The method comprises the following steps: detecting the rotating speed value and running distance value of a motor in a starting process in real time; comparing according to the running distance value of the motor and the maximum rotating speed distance value of the motor, and judging whether the motor is in a rotating speed increasing process or a rotating speed decreasing process, wherein the maximum rotating speed distance value refers to the running distance of the motor of which the rotating speed reaches a maximum value in the starting process; if the current rotating speed of the motor is less than a first threshold value W1 in the rotating speed increasing process, performing anti-clamping protection; and if the current rotating speed of the motor is less than a second threshold value W2 in the rotating speed decreasing process, performing anti-clamping protection. According to the method, an anti-clamping threshold value can be calculated according to practical conditions, and an anti-clamping function of the motor is realized in the starting process of the vehicle body closing system.

Description

technical field

[0001] The invention relates to the technical field of control of a vehicle body closing system, in particular to a method and system for judging an anti-pinch of a vehicle body closing system. Background technique

[0002] Automobiles, trains, subways and other means of transportation have become an indispensable part of people's lives. While these devices are being used in large quantities, the safety requirements for vehicles are attracting more and more attention. The anti-pinch performance of the body closure system is a very important link, which is directly related to the safety of passengers and property.

[0003] The existing anti-pinch system basically adopts the following method: store the mechanical component parameters of the whole process of the last time the body closing system is normally closed in the memory of the body closing system. During the closing process of the vehicle body closing system, compare the real-time parameter values ​​of...
