Anti-pinch control method for electric sunroof

Abstract

An anti-pinch control method for an electric sunroof comprises controlling the closure of the sunroof when an instruction of closing the sunroof is received; calculating an average torque value when the sunroof runs in a stable area; calculating a load torque T currently outputted by a motor when the sunroof runs in an air-guiding plate area, determining a current stroke N0 when the sunroof is in the air-guiding plate area, and obtaining a value inquired from a set reference array, wherein delta T = T - T1, and controlling the sunroof to open when delta T < nabla T[N0]*P, controlling the sunroof to close when delta T > nabla T[N0]*P, controlling the sunroof to open when delta T > nabla T[N0]+K and controlling the sunroof to close when delta T < nabla T[N0]+K. By using the above-mentioned scheme, the anti-pinch control method for the electric sunroof provided in the invention improves the stability of anti-pinch judgment.

Description

technical field

[0001] The invention belongs to the field of skylight anti-pinch methods, and in particular relates to an electric skylight anti-pinch control method. Background technique

[0002] The electric window is to drive the sunroof to open, close, tilt up and down through the vehicle power supply. Passengers only need to press the key switch that controls the sunroof lightly, and the sunroof will automatically open, close, tilt up and down. Although electric windows have brought a lot of convenience to passengers, there are also some disadvantages. For example, when passengers extend their hands or objects out of the sunroof, if they accidentally press the key switch that controls the closing of the sunroof, the passengers are prone to be caught. Accidents where closing or falling glass gets caught or pinched. Contents of the invention

[0003] In order to solve the technical problem that the existing electric sunroof is easy to pinch passengers, the invention pr...
