Problems solved by technology

[0002] In related technologies, when the vehicle is driving at high speed or on a bumpy road, the motor speed of the window, sunroof or partition system of the vehicle is prone to abnormal fluctuations, which may easily cause false detection of the anti-pinch module of the vehicle and cause anti-pinch The module bounces back by mistake, causing the vehicle's windows, sunroof or partition system to fail to close normally, resulting in poor user experience

Abstract

The invention discloses an anti-pinch control method and an anti-pinch control system. The anti-pinch control method includes: detecting the current rotational speed of the motor; when the current rotational speed of the motor is greater than the historical rotational speed of the motor and the first difference between the two is greater than a first threshold, the control counter is accumulated; when the historical rotational speed of the motor is greater than the current rotational speed of the motor And when the second difference between the historical rotational speed of the motor and the current rotational speed of the motor is greater than the first threshold, control the accumulation of the counter; judge whether the accumulated value of the counter is greater than the preset value, and execute the preset value when the accumulated value of the counter is greater than the preset value. The operation of compensating the anti-pinch threshold value; the step of performing the operation of compensating the preset anti-pinch threshold value includes: recording the maximum difference between the first difference value and the second difference value in the accumulation process of the counter, and adding the maximum difference value Preset the anti-pinch threshold to obtain the current anti-pinch threshold; judge whether the second difference after the current anti-pinch threshold is greater than the current anti-pinch threshold, if so, the anti-pinch module performs anti-pinch rebound.

Description

technical field [0001] The invention relates to the field of vehicle anti-pinch technology, in particular to an anti-pinch control method and an anti-pinch control system. Background technique [0002] In related technologies, when the vehicle is driving at high speed or on a bumpy road, the motor speed of the window, sunroof or partition system of the vehicle is prone to abnormal fluctuations, which may easily cause false detection of the anti-pinch module of the vehicle and cause anti-pinch The module rebounded by mistake, which caused the windows, sunroof or partition system of the vehicle to fail to close normally, and the user experience was poor. Contents of the invention [0003] The invention provides an anti-pinch control method and an anti-pinch control system. [0004] An anti-pinch control method according to an embodiment of the present invention is used for a vehicle, the vehicle includes a motor and an anti-pinch module, and the anti-pinch control method in...
