Embodiment

[0030] This embodiment provides a sunroof noise reduction control method that can reduce the noise during sunroof operation. The sunroof operation is driven by a motor with an encoder to control the output of the motor, such as figure 1 As shown, including the following steps:

[0031] S1: Motor speed calibration step (the modification step can be that the motor speed calibration step of S1 is performed when the sunroof is installed on the car and before leaving the factory. Or it is performed in a 4S shop after the car has been running for a period of time), including,

[0032] S11: Segment the orbit of the skylight, the distance of the orbit is M, the segment distance is m, m=10%-20%M, usually a segment of 5-10cm, the position coordinates are established by segmentation, usually The starting point is the origin;

[0033] The segmentation can also be carried out by the following method: run the sunroof on the track at a fixed output speed of the motor and collect the noise value, es...

Abstract

The invention relates to a noise reduction and control method for a smart skylight, which can reduce noise during the skylight running. By a control curve formed by a power calibration step, the skylight always runs at the positions with the optimum noise level at each segment. An average noise value under normal output of motor drive is used as a reference value, the running speed of the skylightis fast, and running too slowly in the pursuit of noise reduction is prevented. By the smooth processing for the position and an output speed curve, the control failure of a motor due to the output speed changing suddenly can be prevented.

Description

Technical field [0001] This application belongs to the technical field of automobile manufacturing, and particularly relates to a noise reduction control method for an intelligent sunroof. Background technique [0002] The car sunroof is installed on the roof of the car, which can effectively circulate the air in the car and increase the entry of fresh air. At the same time, the car windows can also open up the field of view to facilitate the observation of the scenery and the shooting needs of mobile photography. The car sunroof is composed of a transparent glass window, a track, and a motor. The motor drives the transparent glass window to run on the track, thereby opening or closing the window. [0003] However, due to assembly errors and dust accumulation on the track during the operation of the sunroof of the car, the track may be deformed or dust accumulated during operation, resulting in abnormal noise when running to a certain area, which is very harsh and affects the comfo...
