Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] During the closing process of the electric sunroof, it is very likely that there will be objects trapped in the area of ​​the wind deflector. Therefore, in order to avoid the technical problem that the existing electric sunroof is easy to pinch passengers, the present invention aims at the possible inclusions in the area of ​​the wind deflector. An electric sunroof anti-pinch control method capable of accurately anti-pinch is provided. In the process of controlling the operation of the sunroof in the direction of closing, the method first calculates the average val...

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...
