The present invention relates to an electronic vacuum pump (EVP) controller for a vehicle, capable of controlling an EVP directly affecting braking of a vehicle through a separate switching element, rather than by an electronic control unit (ECU), or the like, capable of preventing a vehicle accident that can occur as vacuum is not formed in a booster, in advance. The electronic vacuum pump (EVP) controller for a vehicle comprises: a vacuum sensor (20) operated upon receiving a low voltage provided from a vehicle, among voltages applied from a battery (40), continuously sensing a vacuum state of a booster, and providing corresponding data; an integrated circuit (IC) (80) performing an operation on the sensed data from the vacuum sensor (20) and transferring an operation result to a switching element (30); the switching element (30) operating and controlling an opening and closing unit (50) using an electrical signal according to the operation result from the IC (80); and the opening and closing unit (50) operated upon receiving power from the battery (40), easily coping with a large current and voltage, and operating and controlling an EVP (60) upon receiving a control signal from the switching element (30).

    본 발명은 차량의 제동에 직접적인 영향을 미치는 전자 진공 펌프(EVP, Electronic vacuum pump)를 엔진제어장치(ECU, Electronic Control Unit)등에 의해 제어되지 않고 별도의 스위칭 소자를 통해 제어가 될 수 있도록 한 차량용 전자 진공 펌프 제어기에 관한 것으로, 배터리(40)에서 인가되는 전압 중 차량에서 제공되는 저전압을 공급받아 작동을 하며, 부스터의 진공상태를 연속적으로 감지하여 데이터로 제공하는 진공센서(20)와, 상기 진공센서(20)에서 감지한 데이터를 연산 처리하여 스위칭 소자(30)로 전달하는 집적회로(80)와, 상기 집적회로(80)의 연산결과에 따라 전기적 신호를 이용하여 개폐수단(50)을 작동 및 제어하는 스위칭 소자(30)와, 상기 배터리(40)의 전원을 공급받아 작동을 하며, 대용량의 전류 및 전압에 용이하게 대응하는 한편, 스위칭 소자(30)의 제어신호를 입력받아 전자 진공 펌프(60)를 작동 및 제어하는 개폐수단(50)을 포함하여 구성된다.
