Abstract

The invention discloses a method and a system for anti-clamping judgment of a vehicle body closing system. The method segmenting the running position of the vehicle body closing system to rebuild mechanical characteristic average value of each segment, utilizing difference of real-time mechanical characteristic value of each running position in the segment and the rebuilt mechanical characteristic average value of the segment of the running position as the basis of clamping. The method resolves the problem of complex compensation caused by effects of environment factor (temperature, voltage and the like) and time change (transformation, aging, abrasion and the like) on running characteristics of the vehicle body closing system, improves system stability and improves anti-clamping judgment accuracy.

Description

technical field [0001] The invention relates to the electrical field, in particular to a method and system for judging anti-clamping of a vehicle body closing system. Background technique [0002] The body closing system refers to the doors, windows, sunroof and back door of the car. Among them, the anti-pinch means that after the doors, windows, sunroof and back door clamp objects and reach a certain force during the closing process, the electric car doors and windows will , the sunroof and the rear door automatically stop or fall back to prevent objects (especially the human body) from being pinched. During the opening and closing process of the body closure system, only when the body closure system is closed, anti-pinch control is required. The anti-pinch area of ​​the window is defined as 4-200mm from the maximum position (top) of the electric window glass for barrier-free closing. Area. This definition complies with the relevant requirements of European 74 / 60 / EEC and ...
