Abstract
The invention relates to a window lifting in-place intelligent control circuit without a limit switch, which comprises left and right window lifting motors, left and right window lifting switches, a right window motor locking switch and a left-control right window lifting switch. A left window lifting timer, a left window lifting motor current sampler, a left window lifting motor current comparator and a left window lifting motor power supply control switch are arranged in a window lifting controller; and a right window lifting timer, a right window lifting motor current sampler, a right window lifting motor current comparator and a right window lifting motor power supply control switch are also arranged in the window lifting controller. According to the invention, windows are controlled to lift and descend by detecting window motor currents and timing and the limit switch of hardware is totally canceled. The window lifting in-place intelligent control circuit without the limit switch has a window anti-pinch function, has no requirement on a space in a vehicle door assembly, has few faults and low cost and is convenient to use.
Description
Technical field
The window lifting that the present invention relates to a kind of infinite place switch control circuit that puts in place.
Background technology
At present the window lifting of general vehicle puts in place and adopts mechanical switch or inductive switch to differentiate and control usually, and there is following point in this method: 1, position and the space to installation and control switch in the car door assembly has higher requirements; 2, gauge tap damages back maintain and replace difficulty; 3, vehicle window controller problems such as cost have in addition been increased.
Summary of the invention
The object of the invention is exactly to provide in order to overcome the above problems a kind of mechanical switch or inductive switch of need not to differentiate and control, and window lifting that the Car window electric machine up-down puts in place the infinite place switch intelligence control circuit that puts in place is controlled in size through detecting the vehicle window motor operating current and timing.
Technical scheme of the present invention is achieved like this: a kind of window lifting infinite place switch intelligence control circuit that puts in place comprises left window lifting motor M1, left window direction switch K1, right window electric motor locking K switch 2, the right window direction switch K3 of left side control, right window direction switch K4, right window lifting motor M2, window lifting controller; Be characterized in: the left window lifting motor current comparator Y1 that also is provided with left window up-down timer T1, left window lifting motor current sampler A1 in the described window lifting controller N, left window lifting motor electric current is compared and enlarged, by the left window lifting motor power control switch of the time control electric machine of left window working power of the output of left window lifting motor current comparator and left window up-down timer; The right window lifting motor current comparator Y2 that also is provided with right window up-down timer T2, right window lifting motor current sampler A2 in the described window lifting controller N, right window lifting motor electric current is compared and enlarged, control the right window lifting motor power control switch of right window machine operation power supply by the time of the output of right window lifting motor current comparator and right window up-down timer.
The present invention controls window lifting through detecting vehicle window current of electric and timing, has fully phased out the limit switch of hardware, has the anti-pinching car window function, and to space no requirement (NR) in the car door assembly, fault is few, cost is low, easy to use.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
Among the figure: E-battery; M1-left window lifting motor; K1-left window direction switch; K2-right window electric motor locking switch; K3-right window the direction switch of left side control; K4-right window direction switch; M2-right window lifting motor; N-window lifting controller; T1-left window up-down timer; T2-right window up-down timer; A1-left window lifting motor current sampler; A2-right window lifting motor current sampling circuit; Y1-left window lifting motor current comparator; Y2-right window lifting motor current comparator; D1-left window lifting motor power control switch; D2-right window lifting motor power control switch.
The specific embodiment
Visible by Fig. 1: as to the present invention includes left window lifting motor M1, left window direction switch K1, right window electric motor locking K switch 2, the right window direction switch K3 of left side control, right window direction switch K4, right window lifting motor M2, window lifting controller N.The left window lifting motor current comparator Y1 that also is provided with left window up-down timer T1, left window lifting motor current sampler A1 in the window lifting controller N, left window lifting motor electric current is compared and enlarged, by the left window lifting motor power control switch of the time control electric machine of left window working power of the output of left window lifting motor current comparator and left window up-down timer; The right window lifting motor current comparator Y2 that also is provided with right window up-down timer T2, right window lifting motor current sampler A2 in the window lifting controller N, right window lifting motor electric current is compared and enlarged, control the right window lifting motor power control switch of right window machine operation power supply by the time of the output of right window lifting motor current comparator and right window up-down timer.
Window lifting controller N monitors jacking system in real time during work; The one, through comparison to a left side/right window lifting motor sample rate current peak value; The 2nd, through to the comparison of time parameter (this parameter be by the empirical parameter that test result draws that puts in place of window lifting repeatedly) is set; Whether the two combines to differentiate vehicle window goes up and down to put in place and controls opening and stopping of Car window electric machine, and has the anti-pinching car window function.
After window lifting controller N switches on:
(1) there are the request of " liter " or " falling ": a, window lifting controller N to drive the work of left window lifting motor when detecting left window direction switch; Simultaneously left window lifting motor electric current is carried out real-time sampling and compare; The sampling and relatively after find glass be raised to the position locked rotor current Imax1 (locked rotor current of window lifting motor is a characterisitic parameter of motor); When actual measurement sample rate current I1 satisfied Imax1≤I1≤Imax1 * (1+30%), window lifting controller N controlled left window lifting motor and works on and judge that left window is raised to the position and stops the work of left window lifting motor behind the 200ms; B, pick up counting,, judge that then left window is raised to the position and stops the work of left window lifting motor when cumulative time T satisfies T=Tmax (Tmax put in place for window lifting repeatedly the time empirical parameter that test result draws).
(2) there are the request of " liter " or " falling ": a., window lifting controller N to drive the work of right window lifting motor when detecting right window direction switch; Simultaneously right window lifting motor electric current is carried out real-time sampling and compare; The sampling and relatively after find glass be raised to the position locked rotor current Imax2; When actual measurement sample rate current I2 satisfied Imax2≤I2≤Imax2 * (1+30%), window lifting controller N drove right window lifting motor and works on and judge that right window is raised to the position and stops machine operation behind the 200ms; B, pick up counting, judge then that when cumulative time T satisfies T=Tmax right window is raised to the position and stops machine operation.
