Abstract

A self-adapting car window anti-clamping control circuit comprises a controller unit (1), a Hall sensor (2), a detection circuit (3) and a driving circuit (4). The controller unit (1) is connected with a car window motor (5) through the driving circuit (4), simultaneously parametric variation in an operation process of the car window motor (5) is connected with the controller unit (1) through the detection circuit (3), and the controller unit is connected with the Hall sensor (2) through an external interruption pin. A self-adapting car window anti-clamping control method has twelve steps. The brand new drive circuit is provided to solve the problem that a motor driving chip in a car is insufficient in driving capability and apt to generate heat and a current method in the anti-clamping control field is poor in universality, and further the self-adapting car window anti-clamping control method is provided. The control circuit and the control method have good application value and wide application prospect in the technical field of car auxiliary safety devices.

Description

technical field [0001] The invention relates to an adaptive window anti-pinch control circuit and a control method, in particular to an anti-pinch circuit and an implementation method for indirectly detecting the closing force of a vehicle window through an electric current, and belongs to the technical field of automobile auxiliary safety devices. Background technique [0002] With the development of automotive electronic technology, more and more electronic devices are installed and used in automobiles, and intelligent electric window systems are also put into use. Electric car windows have caused too many accidents of pinching people since their application, and anti-pinch windows came into being. [0003] The main issues to be considered in the anti-pinch algorithm design process are anti-pinch area detection, anti-pinch force calibration, window parameter changes and environmental changes. Using methods such as infrared and mechanical sensors widely used in other field...
