Abstract:
본발명은아웃사이드미러용구동회로에관한것으로서, 더욱상세하게는차량의전동식아웃사이드미러를작동시키는모터구동용회로에관한것이다. 즉, 본발명은아웃사이드미러구동회로에 3개의하프브릿지를채택하여, 아웃사이드미러전용의원 칩(One chip)을더욱소형화시키는동시에회로기판의크기도더욱줄일수 있고, 불필요한와이어링개수도보다줄일수 있도록함으로써, 아웃사이드미러의전반적인제어신뢰성은그대로유지하면서조립작업효율을증가시킬수 있고, 원가절감효과도얻을수 있도록한 아웃사이드미러용구동회로를제공하고자한 것이다.

본발명은 CAN 네트워크에서패킷을인증하는방법에관한것으로, 보다상세히는분할및 혼합된메시지인증코드를이용한효율적인인증방법및 이를위한장치에관한것이다. 본발명의일 실시예에따른 CAN 네트워크에서메시지를혼합메시지인증코드(MAC)를이용하여전송하는방법은제 1 메시지를이용하여제 1 MAC을생성하는단계; 상기제 1 MAC을제 1 부분 MAC 및제 2 부분 MAC으로분할하는단계; 제 2 메시지를이용하여제 2 MAC을생성하는단계; 상기제 2 MAC을제 3 부분 MAC 및제 4 부분 MAC으로분할하는단계; 상기제 2 부분 MAC 및상기제 3 부분 MAC을선형연산하여제 1 인증 MAC을생성하는단계; 상기제 1 메시지를상기제 1 부분 MAC과함께전송하는단계; 및상기제 2 메시지를상기제 1 인증 MAC과함께전송하는단계를포함할수 있다.
Abstract:
PURPOSE: A driving circuit for an outside mirror is provided to remarkably reduce size of a circuit board and one chip of the outside mirror by picking 3 half bridges. CONSTITUTION: A driving circuit for an outside mirror comprises a MCU(Motor Control Unit)(10), a power supply unit(12), a logic chip(14), and 3 half bridges(21,22,23). The MCU controls drive of a motor. The power supply unit provides power source for an IC(Integrated Circuit) drive. The logic chip is connected to the MCU and exchanges signals with the MCU. The 3 half bridges transfer signals of the logic chip to the motor. The 3 half bridges is connected to a folding motor(31), an up/down motor(34), and a left/right motor(37) in series and in parallel.
Abstract:
PURPOSE: A door connector for a vehicle is provided to execute the fastening and releasing work easily by manipulating a side lever, not putting in a hand between the vehicle body and the door. CONSTITUTION: A door connector for a vehicle includes a male connector housing, a female connector housing, a lever, and a slide. The male connector housing(312) is electrically connected to a female connector(300). The female connector housing(302) is electrically connected to a male connector(310). The lever(304) is mounted on the female connector housing for coupling between the female and male connectors. The slide(306) is mounted on the lever and has a guide hole coupled with a protrusion(314) formed on the side of the male connector housing.
