Abstract

본 발명은 차량이 주행 중 갑자기 엔진이 정지되었을 때 기관의 흡입 부압이 부족해지면서 제대로 제동력을 발휘하지 못하게 되는 것을 방지토록 하는 주행 중 엔진 정지시의 제동장치에 대한 것으로 이를 위해 차속은 제로이상이고, 엔진 회전수가 제로상태가 되면 이를 전자 제어 장치가 체크하여 릴레이를 작동시켜 배터리 전원을 진공 펌프에 공급되도록 하고, 상기 진공 펌프에 의해 생성된 진공은 3웨이 밸브를 통해 브레이크 부스터로 공급되도록 하여 시동이 꺼지더라도 배력식 제동이 계속 유지될 수 있도록 하는 구성이 되도록 하여 주행 중 갑자기 차량 시동이 꺼지면서 제동력이 저하되는 것을 자동으로 방지되도록 하므로서 안전한 제동성을 항상 유지되도록 하면서 제동성에 대한 신뢰도를 향상시키도록 하는 구조에 대한 것이다.The present invention relates to a braking device for stopping the engine during driving to prevent the engine from suddenly stopping while the engine is suddenly stopped while the engine's intake negative pressure is insufficient, so that the vehicle speed is more than zero. When the engine speed reaches zero, the electronic control unit checks this and operates a relay to supply battery power to the vacuum pump, and the vacuum generated by the vacuum pump is supplied to the brake booster through a three-way valve to start the engine. It is designed to maintain the hydraulic braking even when it is turned off, so that the braking force is automatically reduced while the vehicle is suddenly turned off during driving, so that the safety braking is always maintained and the reliability of braking is improved. It is about the structure.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 실시예 구조도.1 is a structural diagram of an embodiment according to the present invention.

제2도는 종래의 제동 배력 장치의 구조도.2 is a structural diagram of a conventional braking booster.

Claims (1)

차속은 제로이상이고, 엔진 회전수가 제로상태가 되면 이를 전자 제어 장치가 체크하여 릴레이를 작동시켜 배터리 전원을 진공 펌프에 공급되도록 하고, 상기 진공 펌프에 의해 생성된 진공은 3웨이 밸브를 통해 브레이크 부스터로 공급되도록 하여 시동이 꺼지더라도 배력식 제동이 계속 유지될 수 있도록 하는 구성을 특징으로 하는 주행 중 엔진 정지시의 제동장치.If the vehicle speed is more than zero and the engine speed reaches zero, the electronic control unit checks this and activates a relay to supply battery power to the vacuum pump, and the vacuum generated by the vacuum pump is brake booster through a three-way valve. And a braking device when the engine is stopped while driving, characterized in that the hydraulic brake is maintained so that it is maintained even when the ignition is turned off. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
