Description

제동거리 표시장치를 구비하는 차량Vehicle with braking distance display

본 발명은 제동거리 표시장치에 관한 것으로, 보다 상세하게는 현재 주행하는 차량의 주행속도의 상태에서 차량에 장착된 유압식 제동장치에 의해 제동되는 제동거리를 계기판에 표시되도록 함으로서 운전자가 항상 적절한 차간 거리를 유지할 수 있도록 하는 제동거리 표시장치가 구비되는 차량(Vehicle for having a device displayed braking-range)에 관한 것이다.The present invention relates to a braking distance display device, and more particularly, to allow the driver to display a braking distance braking by a hydraulic braking device mounted on the vehicle on the instrument panel in a state of driving speed of a vehicle currently running. The present invention relates to a vehicle having a braking distance display device capable of maintaining a vehicle.

ABS(antilock brake system)는 차량의 제동시에 각 차륜의 휠 실린더에 가해지는 제동유압을 감압 또는 증압하여 압력을 조절함으로 적당한 코너링 포스를 확보하여 조향성을 유지하면서 동시에 차량이 가장 짧은 거리로 정지할 수 있도록 제어하는 장치로서, 이러한 제어는 자동차의 전자제어장치인 전자제어유니트(ECU)에서 수행된다.ABS (antilock brake system) controls the pressure by reducing or increasing the braking hydraulic pressure applied to the wheel cylinders of each wheel when braking the vehicle to secure proper cornering force and maintain steering while simultaneously stopping the vehicle at the shortest distance. As a control device, such control is performed in an electronic control unit (ECU) which is an electronic control device of a vehicle.

전자제어유니트에서는, 휠 속도 센서로 부터 입력되는 신호에 의해 각 차륜의 속도, 각 차륜의 가감 속도 및 추정 차체 속도를 계산하고, 이 추정 계산된 데이타에 따라 휠 실린더에 인가되는 유압을 증압 또는 감압 되도록 함으로써, 적합한 최적의 제동력을 얻을 수 있도록 제어한다.In the electronic control unit, the speed of each wheel, the acceleration / deceleration speed of each wheel, and the estimated body speed are calculated based on a signal input from the wheel speed sensor, and the hydraulic pressure applied to the wheel cylinder is increased or reduced in accordance with the estimated calculated data. In order to achieve the optimum optimum braking force, control is performed.

그러나, 상기와 같은 ABS 제어장치는, 각 휠에 장착된 휠 속도 센서로 부터 입력되는 값만을 가지고 차량의 속도 및 차량의 슬립률 등을 계산하여 추정하고, 이 추정된 데이타에 의하여 각 휠 실린더에 인가되는 유압의 가감을 제어하여 제동력을 얻지만 운전자는 현재의 차량속도에서 얻어지는 제동력에 의해 차량이 제동되는 제동거리를 알 수 없으므로 주행중에 적절한 차간거리를 유지하지 못하여 사고가 발생되는 문제점이 있다.However, the ABS controller as described above calculates and estimates the vehicle speed and the slip ratio of the vehicle using only the values input from the wheel speed sensors mounted on each wheel, and calculates and estimates the vehicle speed and the slip ratio of the vehicle based on the estimated data. The braking force is obtained by controlling the applied or reduced hydraulic pressure, but the driver cannot know the braking distance at which the vehicle is braked by the braking force obtained at the current vehicle speed.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 현재 주행하는 차량의 주행속도의 상태에서 차량에 장착된 유압식 제동장치에 의해 제동되는 제동거리를 계기판에 표시되도록 함으로서 운전자가 항상 적절한 차간 거리를 유지할 수 있도록 하는 제동거리 표시장치가 구비되는 차량을 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to display the braking distance braking by the hydraulic braking device mounted on the vehicle in the state of the traveling speed of the currently running vehicle on the instrument panel The present invention provides a vehicle equipped with a braking distance display device which enables the driver to always maintain an appropriate vehicle distance.
