The requirement of having gone out property.
Power windows be use the device such as motor, lifter, switch to control the lifting of glass for vehicle window, he
There is switch convenient, can operate multiple vehicle window simultaneously, the advantage such as remote controlled.If but misoperation
Security incident the most easily occurs.The most all occurred child blocked by automobile electric window be choked to death time
Between.For safety, exploitation has the vehicle window control module of pinch resistant functionality is the most necessary.
Anti-pinching car window mainly considers anti-pinch regionally detecting, anti-grip force, vehicle window Parameters variation and road condition change thereof etc..
Common power window clamp prevention typically uses electric current testing, and it uses the fault electricity of monitoring Car window electric machine in real time
Stream, it is judged that whether vehicle window clamps foreign body, and the method hardware cost is higher, software algorithm is complicated, and accuracy
The highest, precision is relatively low, it is impossible to promote in low price car, and is easily caused anti-pinch by mistake by ectocine.
And anti-pinch current threshold changes with the change of vehicle, service condition etc., and need a large amount of before application
Test, portable poor.
Summary of the invention
Present invention aims to the defect that prior art exists, it is provided that one is realized with a low cost vehicle window and prevents
Folder function and precision height, the automobile-used clamp prevention controller of safety and stability.
For reaching above-mentioned purpose, the present invention uses following technical proposals: a kind of car based on dual-Hall sensor
With clamp prevention controller, the input being connected with Micro-processor MCV including power circuit, Micro-processor MCV
The control of interface circuit, motor-drive circuit, position sensing circuit, motor-drive circuit and Micro-processor MCV
End signal processed connects, and described position sensing circuit is dual-Hall sensor circuit, and Micro-processor MCV is to car
Window demarcates the detection dutycycle of hall device pulsewidth, vehicle window is formed and each position of vehicle window in normal uphill process
Motor rotations and the moment of torsion of each position, Car window electric machine rotates and makes to be arranged on and has phase contrast on motor
Dual-Hall sensor send two Hall square-wave signals of rule respectively, and send into processor MCU controller,
Direction of motor rotation, motor rotations, window travel position is judged by calculating contrast two Hall square-wave signals,
And calculate the moment of torsion of real electrical machinery according to motor rotations rate of change, and judge have on vehicle window compared with calibration value
Clear, drives motor reversal or stall to realize pinch resistant functionality.
As one improve: dual-Hall sensor circuit respectively with Micro-processor MCV position I/O message number
Connect.
Improve as one: sentenced by the phase contrast relation contrasting two Hall square-wave signal rising edges or trailing edge
Power machine rotation direction forward or reverse.
Improve as one: the Hall element initial offset angle that two are arranged on motor is less than or equal to 90 °.

Rate curve, when curvilinear motion reaches anti-grip force threshold value, Micro-processor MCV control motor powered vehicle window
Glass reversion or stall, it is achieved anti-pinch.
The invention have the advantage that owing to position sensing circuit have employed dual-Hall sensor circuit, obtain in real time
Vehicle window in the moment of torsion of each position, done with high accuracy anti-pinch, and hardware configuration is simple, software algorithm is convenient,
Low cost.The stroke recording mistake being simultaneously avoided that motor by mistake to distinguish rotation direction and to cause, makes vehicle window close not
The problem such as tight.
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright it is described in further detail.
Accompanying drawing explanation
Fig. 1 is the block diagram of a kind of automobile-used clamp prevention controller based on dual-Hall sensor of the present invention.
Fig. 2 is the circuit theory diagrams of a kind of automobile-used clamp prevention controller based on dual-Hall sensor.
Detailed description of the invention
A kind of embodiment of the present invention automobile-used clamp prevention controller based on dual-Hall sensor, including power circuit
Input interface circuit B that A, Micro-processor MCV are connected with Micro-processor MCV, motor-drive circuit C,
Position sensing circuit D, Lin transceiver module E, push button signalling input circuit F, key signal circuit G, electricity
Drive circuit is connected with the control end signal of Micro-processor MCV, dual-Hall sensor circuit respectively with micro-place
Reason device MCU position I/O message number connects.Described position sensing circuit is dual-Hall sensor circuit,
Vehicle window is demarcated the detection dutycycle of hall device pulsewidth by Micro-processor MCV, vehicle window is formed and normally rose
The motor rotations of each position of vehicle window and the moment of torsion of each position in journey, Car window electric machine rotates and makes to be arranged on
Have dephased dual-Hall sensor on motor and send two Hall square-wave signals of rule respectively, and at feeding
By calculating contrast two Hall square-wave signals, reason device MCU controller, judges that direction of motor rotation, motor turn
Number, window travel position, and calculate the moment of torsion of real electrical machinery according to motor rotations rate of change, and with demarcation
