Form full-bridge circuit in order to realize soft stop, soft with metal-oxide-semiconductor in the present embodiment, compare the relay drive part of using on the present market, can realize that the PWM controller is that motor slowly starts and slowly stops, actv. protection motor-driven part and whole electric system comprise track glass bar etc.; Increased the testing circuit to external motor, whether opened circuit to detect external motor, perhaps connection lead bonding whether.Being equivalent to has like this increased the self-protection circuit to circuit, can detect the situation of external circuit before motor action, realizes that the oneself of equipment detects and error correction, causes controller equiment to burn under the situation that prevents from externally going wrong.Increase the hardware latching circuit that opens circuit to external motor, to be implemented in the very fast time driving circuit has been realized protection.Adopt the form of hardware self-lock protection, the main software reaction time of considering is slower, makes equipment stop output like this within 0.5mS, is 200 times of reaction time of software design.Realized the work of a plurality of motors of a small amount of chip drives.Adopt 5 4559 chips (the MOSE terminal T pipe of 1 N raceway groove and 1 P raceway groove integrated) to realize that controller is to the rotating operation of 4 motors, the hardware space that reduces and hardware cost.Realize that a small amount of I/O operates the logical action of a plurality of actions.Adopt the decoding design of multiple way switch to realize having saved hardware space and hardware cost with the design of 4 positive and negative dresses of motor of 4 I/O control.
The principle of work of this circuit is as follows:
One, vehicle window work
1, unclamps after pressing respective keys, begin to rise or descend, in process of rising or falling, push button again, stop.
2, push button after, if glass not operation in process of rising or falling, then rise or drop to the end after stop automatically.
3, push button more than 1 second, glass rises when button or descends, unclamp button after, glass action stops.
4, continue 〉=7A when the Car window electric machine electric current, time length 40 ± 20mS thinks that stall is effective.
If 5, locked rotor current do not occur when vehicle window button weak point Car window electric machine when rising or descending in 12S, vehicle window controller stops the output to Car window electric machine.
If twice stall of 6 equidirectional appearance when rising or descending, it is invalid that the equidirectional button in back is pressed the back again, presses or recover ON retaining blackout or the power supply back of stopping power supply up to the reversing sense button; When ON retaining blackout or the power supply button of stopping power supply is pressed number of times and made zero.
7, before Car window electric machine work, the existence of detection motor coil is opened circuit or the motor connection lead exists bonding or connection lead existence to open circuit, stop operation this time, and the vehicle window controller all functions lost efficacy, after R and L indicator lamp continue 1min with the 50% common flicker of terminal T=0.5S dutycycle simultaneously simultaneously, functional rehabilitation is normal, if ON retaining blackout functional rehabilitation is normal during the course.
8, when Car window electric machine is worked, detect motor coil and have short circuit, this operation stops and the vehicle window controller all functions lost efficacy, after R and L indicator lamp replace the lasting 1min of flicker with terminal T=0.5S dutycycle 50% simultaneously simultaneously, functional rehabilitation is normal, if ON retaining blackout functional rehabilitation is normal during the course.
Two, back mirror regulatory function
1, by bottom left or right back visor selection key, corresponding indicator lamp is lighted, and can use this moment the back mirror direction to regulate button and regulate corresponding back mirror.
2, the indicator lamp on the button extinguished after 5 minutes, extinguished if press homonymy button indicator lamp during this period again, reappeared beginning if press the timing of heteropleural button.
Three, back mirror heating
1, press the defrosting button once, the back mirror temperature booster begins heating, the defrosting indicator lamp flicker on the button, and post-heater quit work in 15 minutes.
2, pin the defrosting button more than 1 second, the back mirror temperature booster begins heating, and the defrosting indicator lamp on the button is lighted, and disappearing to heat up to ignition signal just stops.
3, in the heat process, pin the defrosting key and press, temperature booster quits work immediately, and the defrosting indicator lamp on the button extinguishes simultaneously.
4, burner on light is yellow highlighted LED lamp, and when having (green highlighted LED light) backlight under the heating button, backlight being presented at that stops earlier heating under the button lighted burner on light.
Four, door lock control
When pressing the door lock button controller the form output corresponding signal of LIN give lamp dimmer (containing door lock control function).
Five, backlight function
Vehicle window button, back mirror are regulated under rocker switch, door lock rocker switch, the back mirror heating button highlighted green LED lamp, lights when lampet consumption is effective.
