Abstract
The invention discloses a car window glass lifting anti-pinching device. The car window glass lifting anti-pinching device is characterized in that a hall sensor arranged on a car window motor acquires a rotating speed signal of the motor and then sends the rotating speed signal to a processor MCU so that the real-time rotating speed of the motor can be calculated; besides, resistance exerted on a glass lifter is judged according the changing speed and changing rate of the rotating speed; finally, whether a barrier exists on a car window or not is judged, and the motor is driven to rotate reversely to prevent pinching. By the adoption of the structural method, whether the barrier exists in the operating direction of the car window is automatically detected, and when the car window runs into the barrier and certain force is reached, car window glass rotates reversely to prevent a person from being injured. The car window glass lifting anti-pinching device is low in hardware cost and suitable for being applied and popularized in various types of cars.
Description
Technical field
The present invention relates to the automatic control of automobile window glass, particularly a kind of lifting glass for vehicle window anti-jamming device.
Background technology
, towards more intelligent, information-based, comfortableization future development the dependence of electronic module is got more and more at nowadays automobile, and the intelligence degree of electronic module determines the entirety location of automobile.Meanwhile, electronic module function is more and more, more and more refinement, more and more perfect, also more and more harsher to electronic module requirement.
Traditional automobile glass lifter is crank type, rely on greatly to artificial, and time consuming operations is inconvenient, present glass-frame riser is electric model, and the mode of the automatic operation of crawl button is made into from the manual mode that the long-time button of needs is originally pressed, the automatic method of operation has and saves time, labour-saving feature, but there is the hidden danger crushing people simultaneously, existing anti-pinching car window device is by monitoring the fault current of Car window electric machine in real time, be used for judging whether vehicle window clamps foreign matter, hardware cost is higher, cannot promote in low price car, and easily cause anti-pinch by mistake by ectocine.
For the problems referred to above, provide a kind of novel anti-jamming device, realizing vehicle window foreign matter anti-pinch with lower cost is the problem that prior art needs to solve.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of lifting glass for vehicle window anti-jamming device, realizes the function of vehicle window foreign matter anti-pinch with lower cost.
For achieving the above object, technical scheme of the present invention is, a kind of lifting glass for vehicle window anti-jamming device, it is characterized in that: described anti-jamming device comprises after the hall sensor be arranged on Car window electric machine obtains the tach signal of motor sends into the real-time rotate speed that processor MCU calculates motor, and the resistance be applied on glass-frame riser is judged according to rotation speed change speed and relative speed variation, final judgement vehicle window has clear, and drive motors reversion realizes pinch resistant functionality.
Described processor MCU obtains hall sensor passes by catching mode and to come the high/low level duration of square wave, calculates original rotating speed; By rotating speed by algorithm filter, calculate the motor real-time rotate speed after process.
Described processor MCU, by the process of rotary speed data by low pass filter, draws a level and smooth rate curve, and when curvilinear motion reaches anti-grip force threshold value, processor MCU controls the reversion of driven by motor glass for vehicle window, completes a pinch resistant functionality.
A kind of lifting glass for vehicle window anti-jamming device, owing to adopting above-mentioned structure and method, automatic detection vehicle window traffic direction of the present invention has clear, and when vehicle window runs into obstruction, and when reaching certain force, glass for vehicle window reverses, and escapes injury to protect people.Hardware cost is lower, is adapted at various vehicle is applied.

Detailed description of the invention
Processor ECU of the present invention can have clear by automatic detection vehicle window traffic direction, and when vehicle window runs into obstruction, and when reaching certain force, glass for vehicle window reverses, and escapes injury to protect people.
Specifically as Figure 1-4, the present invention includes after the hall sensor be arranged on Car window electric machine obtains the tach signal of motor and send into the real-time rotate speed that processor MCU calculates motor, and the resistance be applied on glass-frame riser is judged according to rotation speed change speed and relative speed variation, final judgement vehicle window has clear, and drive motors reversion realizes pinch resistant functionality.
Processor MCU obtains hall sensor passes by catching mode and to come the high/low level duration of square wave, calculates original rotating speed; By rotating speed by algorithm filter, calculate the motor real-time rotate speed after process.Processor MCU, by the process of rotary speed data by low pass filter, draws a level and smooth rate curve, and when curvilinear motion reaches anti-grip force threshold value, processor MCU controls the reversion of driven by motor glass for vehicle window, completes a pinch resistant functionality.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that technical solution of the present invention is carried out, or directly apply to other occasion, all within protection scope of the present invention without improving.
