Description

전자식 주행안전 장치{Automotive device for Electronic Stability Program} Electronic driving safety device {Automotive device for Electronic Stability Program}

본 발명은 전자식 주행안전 장치에 관한 것으로서, 보다 상세하게는 핸드브레이크신호에 의하여 시스템의 기능을 일시 정지시키는 전자식 주행안전 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic road safety device, and more particularly, to an electronic road safety device for temporarily stopping a function of a system by a hand brake signal.

일반적으로 전자식 주행안전 장치(ESP : Electronic Stability Program)는 차량이 미끄러지려고 할 때 안정성을 유지하기 위하여 순간적으로 네 바퀴를 각각 독립적으로 제어하여 건조한 노면, 빗길, 자갈길, 눈길 등에서 주행안정성을 강화해 주는 장치이며, 위험한 운전상황에서 자동차 스스로 브레이크를 밟거나 엔진토크를 제어하여 위험으로부터 벗어나게 하는 장치이다. ABS가 브레이크를 직접 밟아야 효과를 발휘하고 또 제동하는 과정에서만 효과를 발휘하는 장치라면, 전자식 주행안전 장치는 운전자가 브레이크를 밟지 않아도 스스로 최적의 차량운행조건을 찾아주는 장치이다. 예를 들어 운전자가 통제하기 어려운 속도로 선회를 하고 있을 경우, 자동차에 장착된 전자식 주행안전 장치는 센서를 통하여 얻어진 차량운동량과 추정을 통하여 얻어진 노면상태 등을 이용해 정해진 안정 기준값보다 실제 차량 운동량이 클 경우 적절한 차륜으로 제어함으로서 차량의 안정성을 확보해준다. 후륜에서 먼저 타이어와 노면 사이에 접착한계에 도달하면 오버스티어(Over Steer : 자신이 조작한 조향각보다 더 심하게 조향이 이루어지는 현상) 현상이 나타난다. 이때 전자식 주행안전 장치는 전륜의 제동장치를 제어함으로서 전륜에 의해 발생하는 과도한 선회모멘트를 줄여준다. 반대로 전륜에서 먼저 타이어와 노면의 접착한계에 도달하면 언더스티어(Under Steer : 자신이 조작한 조향각보다도 조향이 덜 이루어지는 현상) 현상이 발생한다. 이때 차량은 미끄러지면서 정상적인 선회반경을 넘어서게 된다. 전자식 주행안전 장치는 이러한 현상 모두를 제어하여 위급한 상황에서 운전자가 원하는 방향으로 차량을 제어하여 안정성과 조향성을 유지시켜주는 시스템이다. In general, the Electronic Stability Program (ESP) enhances driving stability on dry roads, rain, gravel roads and snow roads by controlling four independent wheels instantaneously to maintain stability when the vehicle is about to slide. It is a device to get out of danger by braking or controlling engine torque by car in dangerous driving situation. If the ABS is effective only when the brakes are applied directly and only during the braking process, the electronic driving safety device is a device that finds the optimum vehicle driving conditions without the driver applying the brakes. For example, if the driver is turning at a speed that is difficult for the driver to control, the electronic driving safety device installed in the vehicle may have a larger actual vehicle motion than the stability reference value determined by using the vehicle motion obtained through the sensor and the road condition obtained through the estimation. In this case, the stability of the vehicle is ensured by controlling the vehicle with appropriate wheels. When the rear wheel first reaches the limit of adhesion between the tire and the road surface, an oversteer phenomenon occurs. At this time, the electronic driving safety device reduces the excessive turning moment generated by the front wheel by controlling the braking device of the front wheel. On the contrary, when the front wheel first reaches the adhesive limit between the tire and the road surface, an understeer phenomenon occurs. At this time, the vehicle slides and goes beyond the normal turning radius. The electronic driving safety system controls all of these phenomena to maintain stability and steering by controlling the vehicle in the direction desired by the driver in emergency situations.

그러나, 상기 전자식 주행안전 장치는 차량이 급하게 유턴(U-turn)하고자 할 때 신속한 유턴이 불가능하다는 단점이 있다.However, the electronic driving safety device has a disadvantage in that a quick u-turn is impossible when the vehicle tries to u-turn in a hurry.

The present invention has been made to solve the above problems, in order to enable a quick u-turn when the vehicle wants to U-turn quickly, by detecting the driver's u-turn from the handbrake switch signal, the handbrake Is in the pulled state, the purpose of the vehicle is to temporarily suspend the operation of the electronic driving safety device and provide a means for instructing the driver by the blinking light indicating that the electronic driving safety device is in the disabled state. .
