Embodiment Construction

[0011] Such as figure 1 The electrical block diagram of the automotive electric sunroof controller with memory correction is shown. The control includes input circuit, interface circuit, single-chip microcomputer, motor driver, and sunroof motor. The signal of the input circuit enters the interface circuit and becomes a standard signal and enters the single-chip microcomputer. The single-chip microcomputer sends instructions through Motor driver to control the sunroof motor, C8051F330 MCU 11 detects the motor current signal 1, motor pulse signal 2, zero position signal 3 and 4 function keys in the input circuit through the interface circuit 9 - the sunroof open key 4, the sunroof close key 5, the tilt key The signal of starting / modifying key 6 and position preset key 7. The detection of the current signal 1 is based on the current image function of the MC33486 motor driver 12 , the current signal 1 is converted into a voltage signal through the interface circuit 8 , and conver...

Abstract

The invention relates to an electric sunroof controller with memory correction. Adding a correction key and program processing in the controller can regularly correct the control parameters of the electric sunroof of a car, making up for the changes in control parameters caused by the process of manufacturing, installation and use, so that The performance of the sunroof is kept in top condition, extending the service life.

Description

technical field [0001] The invention relates to a controller, in particular to an automobile electric sunroof controller. Background technique [0002] At present, the car electric sunroof control system is composed of a zero sensor, a motor pulse sensor, a function switch, a motor driver, a current feedback circuit and a central controller. Turning on different function switches can realize the opening, closing, backward tilting, Position preset function, with over-current and anti-pinch protection functions. The current sunroof controller uses the maximum current value during the closing process of the sunroof plus a percentage as the threshold value of the anti-pinch current. When the motor current exceeds this threshold value during the closing process of the sunroof, the controller implements anti-pinch protection, that is, Reverse movement to maximum opening position. In addition, in order to reduce the movement impact when the sunroof is opened to the maximum positi...
