Description
Technical field
The application belongs to vehicle electric field, controls for body electrical function, is specifically related to the control method of a kind of lifting glass for vehicle window.
Background technology
The control method of lifting glass for vehicle window currently mainly has following 2 kind:
1, directly controlled the relay of glass lifting motor by switch, it is open-minded that relay pressed by switch, it is achieved function；This scheme does not possess function of auto-lift, can not accomplish to automatically cut off output in the case of crossing stream and protect motor and circuit simultaneously；
2, controlled by car body controller or door module, switching signal passes to car body controller or the main control chip of door module, after main control chip receives instruction, drive the motion of glass lifting motor, when detecting that the flow currents of motor is more than its starting current 87%, when the numerical value persistent period reaches 400ms, i.e. think that vehicle window arrives top or bottom and cuts off output, the method can realize automatic function and automatically cut off output, but it is excessive and frequently cut off output to easily cause flow currents in cold winter, motor is caused to move, the problem that glass for vehicle window can not lift smoothly.
Summary of the invention
In order to solve the problems referred to above, the invention discloses the control method of a kind of lifting glass for vehicle window, particularly as follows: sample circuit gathers the size of current of each Car window electric machine motion, according to the size of current collected and situation of change, main control MCU judges which kind of state motor is in, carry out opening and stopping of window lifting according to motor state in which.
Wherein,
21) when the electric current checking a motor movement is more than the 62.5% of starting current when, detect whether that the electric current of more than one vehicle window is more than the 62.5% of starting current；
22) when the current of electric determining only one of which vehicle window is more than the 62.5% of starting current, detect whether this current of electric is more than or equal to the 100% of starting current, and persistent period 400ms；
23) when determining that this current of electric is more than or equal to the 100% of starting current, and during persistent period 400ms, the motion of current vehicle window is cut off；
24) when determine this current of electric be not more than or equal to starting current 100% time, perform lifting glass for vehicle window motion.
Wherein,
31) when in step 21) in determine have the current of electric of more than one vehicle window more than starting current 62.5% time, keeps first to enter electric current and enters and continue motion, other vehicle windows time-out more than the vehicle window of starting current 62.5% state；
32) whether the Car window electric machine electric current that detection continues to move is more than or equal to the 100% of starting current, and persistent period 400ms；
33) when determining that current of electric is more than or equal to the 100% of starting current, and during persistent period 400ms, the motion of current vehicle window is cut off.
In step 33) detect whether window lifting switch input signal placed in a suspend state remains in that effectively afterwards, when still effectively, start the lifting action of this vehicle window.
In step 33) after when detecting that a plurality of window lifting switch input signal placed in a suspend state remains in that effective, only start the lifting action of a vehicle window.
Further, the restriction single maximum drive time is 8S.
Hardware circuit design of the present invention is simple, and cost is relatively low；Control window lifting by control strategy, it is possible to protection motor, do not allow its long over loading move, effective ensure that vehicle window has enough electric currents and proper motion in the winter of cold.
Accompanying drawing explanation
Fig. 1: current detecting hardware circuit diagram；
The flow chart of Fig. 2: lifting glass for vehicle window.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is specifically described.
As it is shown in figure 1, access electric motor loop by the series connection of sampling with high precision little valued resistor, the voltage on sampling resistor sends to the AD port of main control chip after amplifying, and then judges the size of current (the most now operating current of motor) in loop.
For convenience of description, left front vehicle window, right front window, left back vehicle window, right vehicle rear window are respectively defined as vehicle window A, B, C, D；Parameter operating current according to vehicle window producer is less than 10.6A, and locked rotor current is less than 24A.
For matched line footpath in hardware designs, A, B being placed under same electric fuse (selecting 30A), B, C are placed under same electric fuse (selecting 30A)；The selection principle of electric fuse is: rated current/0.75, so selecting the electric fuse of 30A.
As shown in Figure 2, when only one of which motor (A motor) is moving when, sample circuit gathers the size of current of vehicle window motor movement, when the electric current collected reaches the 62.5% of starting current when, it is believed that now arrive motor overload state, because starting current can be less than or equal to locked rotor current, and then thresholding is amplified to the 100% of starting current, if continuing 400ms, then think that entrance extreme position, cut-out export；
If there are 2 motors (A motor, B motor) to move simultaneously, but stall occurs the most simultaneously, one enters stall, one proper motion, current maxima now be locked rotor current with flow currents and, these data can be less than or equal to 39(24+24*62.5%=39), parameter according to electric fuse, the electric fuse of 30A is by the electric current of 39A time, effective time is more than 500ms, and under these data, the vehicle window of stall can be again with the numerical value motion 400ms of starting current, if normal condition, after 400ms, cut off output；If under conditions of resistance is relatively big, owing to now thresholding is the 100% of starting current, so this motor can move to extreme position；
If 2 motors move simultaneously, there is (C motor in stall simultaneously, D motor), the most now electric current is the biggest, in order to protect mainboard and circuit, first allow the motor entering stall at first keep under the numerical value of starting current 100% move, another motor power-off pause motion, first motor movement is to (locked rotor current reach starting current 100% continue 400ms) after extreme position, the motor relay above suspended under the conditions of switch is still effective can move by automatic pick, ensure that vehicle window can be elevated to extreme position, as being also only the difference of movement time in the case of the comparison of resistance in winter of cold is big；
Move (A motor, B motor, C motor, D motor) if greater than the motors of more than 2 simultaneously, such as analysis above, if stall occurs, first suspend other motor, more progressively adhesive campaign, in normal conditions, the stall of motor has time delay, the time delay of 4 motors is 2S, and actual test, this time is acceptable；In cold winter, can ensure that vehicle window can normally lift, defect is to lift simultaneously, but in view of actual situation, under lifting is appreciated that the operating modes such as the situation that 4 door and windows lift simultaneously the most in the winter time occurs less, some charge stations the most in order, the motion conditions of single vehicle window is more, now can ensure that vehicle window normally lifts.
