Abstract: 현재 자동차운전을 하면서 여러 가지의 운전상황을 경험하게 된다. 대표적인 예로 자동차를 과속으로 몰던 중 갑작스런 급커브길을 만날 수도 있으며 그리고 자동차를 도난 당하거나 범죄를 일으키고 자동차로 도주를 하여 경찰들이 도난자동차를 찾기 위해 자동차검문, 밀집주택가에서의 난폭운전, 눈길, 빗길에서의 과속운전, 고속도로에서의 과속운전을 하는 것을 누구나 하번씩은 자동차운전을 해보았을 것이고 또한 목격한 적이 있을 것이다. 그리하여 자동차에는 엔진제어장치와 자동차실내의 전자기기제어장치, 운전자에게 알려주는 표시장치를 설치하고 운전을 하는 도로에는 현재의 속도위반몰래카메라 및 도로주의표지판을 대신하여 자동차를 무선으로 제어하도록 하는 제어장치를 도로에 설치하여 자동차운전 중 급커브길 및 밀집주택가, 산악도로를 달릴 때는 자동차를 무선으로 강제로 제어하여 어느 정도의 속도이상은 달리지 못하도록 하고 자동차를 검문하는 검문소 같은 곳에서는 자동차속도는 물론 야간검문시에는 룸램프자동ON 및 주라이트OFF등을 하여 현재 도로에 설치되어 있는 속도위반몰래카메라, 위험도로표지판, 안개, 강변, 암벽주위표지판을 대신하여 자동차를 국가가 직접제어 하여 자동차운전을 하면서 생길 교통사고를 최소한으로 줄이기 위해 발명하였다. 
     이장치로 얻어지는 효과는 다음과 같습니다. 기존의 자동차속도위반몰래카메라, 각종도로주의표지판 대신에 일반자동차 및 사업용차량과 도로에 이장치를 설치하게 되면 자동차 운전중에 잠시후에 있을 도로의 사정을 음성 및 영상표시장치를통해서 정확하게 파악할 수 있게 되며 미리 자동차를 대처할 수 있으며 또한 자동차를 천천히 몰지 않는 경우에는 강제적으로 자동차를 제어하여 속도를 줄이게 되므로 서 안전운전을 하도록 유도를 할 수가 있게 된다. 또한 경찰이 자동차검문을 할 때도 현재는 바리케이트등을 설치하여 자동차의 도주를 막고 있으나 이장치를 설치하게 되므로 서 야간운전시에는 자동으로 룸램프를 ON해주고 주라이트는 OFF해주어 자동차검문을 하는데 편안하게 할 수 있으며 또한 유리를 자동으로 내리도록 하여 자동차 내에 있는 사람을 정확하게 볼 수가 있게 된다. 또한 검문중 도주차량에 경우도 그 자리에서 원격 제어하여 자동차를 서도록 할 수 있으며 또한 현재의 바리케이트등을 철거할 수 있게 된다. 또한 고속도로 같은 곳에서도 자동차를 제어 어느 정도의 속력을 못내도록 하여 교통사고를 줄일 수 있게 된다. 이와 같이 국가적으로 이장치를 설치하게 되면 자동차의 교통사고를 급격하게 줄일 수가 있게 된다. 
     만약 이와 같이 사업용차량(일반버스, 고속버스, 택시, 트럭, 군용특장차)등에 먼저 1차로 설치하여 시험을 해보면 교통사고가 급격하게 주는 것을 확인할 수 있으며 또한 기존의 위험표지판을 설치하는 비용을 이장치로 투자를 하면 각종도로를 지나가기전에 자동차의 속도를 줄이게 되므로 특정이하의 속력으로 자동차를 몰 수 있게 되므로 속도의 위반규제를 해제할 수가 있게되며 이장치를 설치하므로서 교통사고의 방지효과는 확실하게 나타나게 된다. 이와 같이 국가자동차의 속도위반 및 각종위반을 적발하기보다는 자동차를 직접적으로 제어하여 일반적인 도로에서는 현재의 법규규정보다는 완화해주고 이와 같이 위험한 도로에서는 더욱 강하게 자동차를 제어하여 자동차를 제어하는 방법이 좋을 것입니다. 또한 미래의 도로 및 자동차로 버금나게 될 것이다.

Abstract: PURPOSE: A method is provided to easily detect load regardless of slip of a window motor, increase load detection sensitivity and reliability, and make a secure mode applied even when taking off a start key. CONSTITUTION: Whether a window up signal is inputted is judged(S510). If so, a window motor is driven(S515) and variables(K, N) are initialized(S520, S525). A current(Q(N)) flowing at the window motor is measured(S530). A '1' value is added to a state variable value(K)(S535), and a current variation amount(dQ) is calculated(S540). A reference variation amount(delta Q) is calculated based on the state variable value(K)(S545, S555). There is judged whether the current variation amount(dQ) is over the reference variation amount(delta Q)(S560). In case that the current variation amount(dQ) is over the reference variation amount(delta Q), a '1' value is added to a frequency variable(N)(S565). In case that the current variation amount(dQ) is not over the reference variation amount(delta Q), the frequency variable(N) is reset to '0'(S570). There is judged whether a secure mode is operated, based on the frequency variable(N)(S575). In case that the secure mode is not operated, the procedure goes to the step(S530). In case that the secure mode is operated, the secure mode is operated(S580). There is judged whether a first window ascent is caused by input of a start key take-off signal(S585). If so, the procedure goes to the step(S515). If not, the procedure is ended.
