Abstract:
PURPOSE: A control device for a power window is provided to control the half-power range and the weight of a motor control by identifying a driving state and the load condition of the motor in order to output a proper control signal. CONSTITUTION: A control device for a power window comprises a speed profile generation unit(100), a control unit(110), a motor(120), a power window(130), and a sensor unit(140). The speed profile generation unit generates a speed profile by standardizing the speed and output of a motor while normally driving. The control unit determines the half-power range and weight of a motor and subsequently controls the motor through the determined half-power range and weight. The motor drives power windows with variable speed and is controlled by the control unit. The power window is connected with a motor and slows the motor speed by slowing movement according to the state of the motor or the cumulative load. The sensor senses the load condition in the motor, motor speed, and acceleration.

Abstract:
PURPOSE: A drive assist system using image recognition technology is provided to inform signal and lane information which is compatible with driving intention of operators. CONSTITUTION: A drive assist system using image recognition technology comprises a camera input unit(110), a head unit(120), the image processing unit(210), a map information processing unit(220), a driving signal judging unit(230), and a signal output unit(310). The camera input unit records road information and produces image information. The head unit recognizes the current location by using GPS and searches information corresponding to the current location from the predetermined set map information to produce the current map information. The image processing unit extracts image from the video information and produces real road information. The map processing unit produces using map information from the current map information. The driving signal judging unit compares the real road information to the using map information and produces alarm information if error occurs.
