Abstract

PURPOSE: An ABS(Anti-lock Brake System) turns on hold mode of an automatic transmission to activate engine brake on braking to improve braking force. CONSTITUTION: An ABS ECU(2) is connected with a TCU of an automatic transmission. A brake sensor is connected to the ABS ECU. The brake sensor transmits braking signal to the ABS ECU when a brake pedal is treadled during driving. The ABS ECU transmits the braking signal to TCU. The TCU changes the automatic transmission to hold mode. As the automatic transmission is changed to hold mode, the rotational frequency of an engine remains under 1500RPM to activate engine brake. A brake and engine brake work together to improve braking force.

Description

자동차용 안티 록 브레이크 장치Automotive anti lock brake

본 발명은 브레이크 장치에 관한 것으로서, 보다 상세하게는 자동차용 안티 록 브레이크 장치(Anti-Locking Brake System)에 관한 것이다.The present invention relates to a brake device, and more particularly to an anti-locking brake system for automobiles.

일반적으로, 자동차의 브레이크 장치는 푸트 브레이크와 주차 브레이크로 구분되는 바, 상기한 푸트 브레이크는 승용차의 경우 유압을 사용하여 4륜에 장착된 디스크 브레이크 또는 드럼 브레이크를 제어함으로써 자동차의 제동력을 발생시키게 되는 것이다.In general, a brake device of a vehicle is classified into a foot brake and a parking brake. The foot brake generates a braking force of a vehicle by controlling a disc brake or a drum brake mounted on four wheels using hydraulic pressure in a passenger car. will be.

여기서, 상기한 브레이크 장치는 유압으로 회전되는 타이어를 정지시킴으로써 상기한 타이어와 노면의 마찰에 의해 차량을 정지시키게 되는 바, 차량의 주행중 타이어가 록킹되면 노면과 슬립이 발생되고, 이로 인해 정지 거리가 길어지게 되기 때문에 타이어의 슬립을 방지하기 위하여 안티 록 브레이크 장치가 개발되었다.Here, the brake device stops the vehicle by friction between the tire and the road surface by stopping the tire that is rotated hydraulically. When the tire is locked while the vehicle is driving, the road surface and slip are generated, and thus the stopping distance is increased. As it gets longer, anti-lock brakes have been developed to prevent tire slip.

즉, 상기한 안티 록브레이크 장치는 타이어를 록킹시키지 않고 노면과의 마찰력을 최대로 유지하도록 함으로써 정지 능력을 향상시키는 것이다.In other words, the above-described anti-lock brake device improves the stopping ability by maintaining the maximum frictional force with the road surface without locking the tire.

상기한 안티 록 브레이크 장치는 브레이크 페달과, 상기한 브레이크 페달에 연결되어 있을 뿐만아니라 마스터 실린더가 일체로 연결 설치된 부스터와, 상기한 마스터 실린더에 연결된 전, 후륜 브레이크와, 상기한 전, 후륜 브레이크에 설치된 휠센서와, 상기한 마스터 실린더로부터의 유압을 제어하기 위해 전, 후륜 브레이크와의 사이에 설치된 ABS ECU와 모듈레이터로 구성되어 있다.The anti-lock brake device is connected to the brake pedal and the brake pedal as well as to the booster provided in which the master cylinder is integrally connected, the front and rear brakes connected to the master cylinder, and the front and rear brakes. It consists of an ABS ECU and a modulator provided between the wheel sensor provided and the front and rear brakes for controlling the hydraulic pressure from the master cylinder.

즉, 운전자가 브레이크 페달을 밟게 되면 모듈레이터에서 각각의 브레이크로 인가되는 유압을 단속적으로 제어함으로써 타이어가 록킹되지 않을 뿐만 아니라 최대의 제동력을 얻을 수 있도록 하는 것이다.That is, when the driver presses the brake pedal, the tire is not locked and the maximum braking force is obtained by intermittently controlling the hydraulic pressure applied to each brake from the modulator.

그러나, 상기한 바와 같이 안티록 브레이크 장치는 타이어를 록킹시키지 않는 것으로만 제동력을 발생시키게 됨으로써 제동 효과가 낮은 문제점이 있다.However, as described above, the anti-lock brake device generates a braking force only by not locking the tire, thereby causing a low braking effect.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 안티록 브레이크 장착 차량의 제동 효과를 향상시킬 수 있는 자동차용 안티 록 브레이크 장치를 제공함에 있다.Accordingly, it is an object of the present invention to solve the above problems, and to provide an anti-lock brake device for a vehicle that can improve the braking effect of the vehicle with an anti-lock brake.

상기한 목적을 실현하기 위하여 본 발명은 안티 록 브레이크 동작시 자동 변속기의 홀드 모드가 동작되도록 자동 변속기의 TCU와 ABS ECU가 연결되어 있고, 상기한 ABS ECU에 브레이크 센서가 연결되어 있는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the TCU and the ABS ECU of the automatic transmission are connected so that the hold mode of the automatic transmission is operated during the anti-lock brake operation, and the brake sensor is connected to the ABS ECU. .

도면은 본 발명에 따른 자동차용 안티 록 브레이크 장치의 주요부를 도시한 개략도.BRIEF DESCRIPTION OF THE DRAWINGS The schematic diagram which shows the principal part of the anti-lock brake device for automobiles which concerns on this invention.

도면은 본 발명에 따른 자동차용 안티 록 브레이크 장치의 주요부를 도시한 개략도로서, 안티 록 브레이크 동작시 자동 변속기의 홀드 모드가 동작되도록 자동 변속기의 TCU(1)와 ABS ECU(2)가 연결되어 있고, 상기한 ABS ECU(2)에 브레이크 센서(3)가 연결되어 있다.Figure is a schematic diagram showing the main part of the anti-lock brake device for a vehicle according to the present invention, the TCU (1) and the ABS ECU (2) of the automatic transmission is connected so that the hold mode of the automatic transmission is operated during the anti-lock brake operation The brake sensor 3 is connected to the ABS ECU 2.

즉, 자동 변속기가 장착됨과 아울러 안티록 브레이크 장치가 장착된 자동차에서 운전자가 브레이크 페달을 밟게 되면 자동 변속기를 홀드 모드로 전환시킴으로써 엔진 브레이크를 사용하게 되는 것이다.In other words, when the driver presses the brake pedal in an automobile equipped with an automatic transmission and an antilock brake device, the engine brake is used by switching the automatic transmission to the hold mode.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 안티록 브레이크 장치가 설치됨과 아울러 자동 변속기가 설치된 차량이 주행중 브레이크 페달을 밟게 되면 브레이크 센서가 이를 ABS ECU(2)에 전달하게 된다.Referring to the operation and effect of the present invention as described above, when the anti-lock brake device is installed and the vehicle equipped with the automatic transmission depresses the brake pedal while driving, the brake sensor transmits it to the ABS ECU 2.

ABS ECU(2)에 신호가 전달되면 상기한 ABS ECU(2)가 TCU(1)에 브레이크 신호를 전달하게 됨과 아울러 상기한 TCU(1)가 자동 변속기를 홀드 모드로 변환시키게 된다.When the signal is transmitted to the ABS ECU 2, the ABS ECU 2 transmits a brake signal to the TCU 1, and the TCU 1 converts the automatic transmission into the hold mode.

자동 변속기가 홀드 모드로 변환되면 엔진의 회전수 즉, RPM이 1500이하로 유지됨으로써 엔진 브레이크가 동작된다.When the automatic transmission is switched to the hold mode, the engine brake is operated by maintaining the engine speed, that is, RPM, below 1500.

엔진 브레이크가 동작되면 상기한 안티록 브레이크 장치의 동작과 함께 엔진 브레이크가 제동력을 발생시킴으로써 제동력이 보다 향상되는 것이다.When the engine brake is operated, the braking force is further improved by generating the braking force of the engine brake together with the operation of the antilock brake device described above.

즉, 브레이크의 동작과 함께 엔진 브레이크가 동작됨으로써 자동 변속기 및 안티록 브레이크 장치 장착 차량의 제동력이 향상되는 것이다.That is, the braking force of the vehicle with the automatic transmission and the anti-lock brake device is improved by operating the engine brake together with the operation of the brake.

이상과 같이 본 발명은 브레이크 동작시 홀드 모드로 변환됨으로써 엔진 브레이크를 작동시켜 제동력을 향상시킬 수 있는 잇점이 있는 것이다.As described above, the present invention has an advantage of improving braking force by operating the engine brake by being switched to the hold mode during the brake operation.
