Abstract

PURPOSE: An electronic idle speed control actuator is provided to stabilize a system by sensing mechanical action via a non-contact angle sensor. CONSTITUTION: An idle speed actuator(140) comprises a valve assembly(80) and a solenoid assembly(50) controlling a valve(88) of the valve assembly. A permanent magnet(120) is mounted on a shaft(82) of the valve assembly, and recessed portions are formed in both sides of a stator(64) of the solenoid assembly. An angle sensor(150) non-contact to the shaft is embedded. The non-contact angle sensor senses the rotational angle of the actuator and transmits the angle value to an ECU(Electronic Control Unit)(130) for accurate control and decision of defect. The non-contact angle sensor senses the change of the magnetic field due to the rotation of the permanent magnet. Thus, the action of the valve is sensed. The ECU compensates an action signal of the idle speed control actuator by receiving the output from the non-contact angle sensor. Therefore, mechanical defect is decided and informed a user.

In order to control the idle speed of the electronic engine, the flow rate of the intake air is controlled, and the actuator for controlling the flow rate of the intake air needs precise flow rate control. However, electronic idle speed control actuators currently used only sense electrical faults (coil breaks, short circuits and overcurrents). Fixation due to carbonization and failure due to wear of mechanical parts in the product are problems in the idle control system because they cannot sense.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 설명하기로 한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 1을 참조하면, 본 발명에 따른 아이들 스피드 액츄에이터가 도시되어 있다. 본 발명에 따른 아이들 스피드 액츄에이터(140)는 밸브 조립체(80)와 상기 밸브조립체(80)의 밸브(88)를 제어하는 솔레노이드 조립체(50)로 구성된다.1, an idle speed actuator in accordance with the present invention is shown. The idle speed actuator 140 according to the present invention consists of a valve assembly 80 and a solenoid assembly 50 that controls the valve 88 of the valve assembly 80.

상기 밸브 조립체(80)는 공기가 흡입되는 흡입니플(84)과, 공기가 배출되는 배출니플(86)이 구비되고, 상기 흡입니플(84)에서 배출니플(86)로의 배기량을 제어하도록 밸브(88)가 구비된다. 상기 밸브(88)는 밸브시일(16)과의 틈 크기에 의해서 배기량을 제어한다. 상기 밸브(88)는 샤프트(82)에 장착된다.The valve assembly 80 includes a suction nipple 84 through which air is sucked in, and a discharge nipple 86 through which air is discharged, and controls a discharge amount from the suction nipple 84 to the discharge nipple 86. 88). The valve 88 controls the displacement by the gap size with the valve seal 16. The valve 88 is mounted to the shaft 82.

상기 솔레노이드 조립체(50)는 철 성분으로 이루어진 스테이터(64)와, 보빈(58)에 의해서 지지되는 코일(54)과, 상기 코일(54)에 전기를 전달하는 터미널(56)과, 상기 보빈(58)의 외측에 설치된 요크(60)를 포함한다.The solenoid assembly 50 includes a stator 64 made of an iron component, a coil 54 supported by the bobbin 58, a terminal 56 transferring electricity to the coil 54, and the bobbin ( And a yoke 60 provided outside of 58.

상기 솔레노이드 조립체(50)는 ECU(130)로부터의 신호에 의해서 작동된다.The solenoid assembly 50 is actuated by a signal from the ECU 130.

상기 샤프트(82)의 상부에는 영구자석(120)이 장착되고, 스테이터(64)는 도 3과같이, 양측에 오목부(122)가 형성된다.The upper portion of the shaft 82 is a permanent magnet 120 is mounted, the stator 64, as shown in Figure 3, the recess 122 is formed on both sides.

상기 샤프트(82)와 비접촉식인 각도 센서(150)가 내장된다.An angle sensor 150 which is in contact with the shaft 82 is embedded.

상기와 같은 구성에 의해서 본 발명에 따른 자동차용 주행 기록 시스템은 다음과 같이 작동된다.By the above configuration, the vehicle driving record system according to the present invention operates as follows.

일반적으로 ECU(130)에서 동작 신호는 듀티비로 출력되며 그 값이 높을 수록 로터리형 전자식 아이들 스피드 콘트롤 액츄에이터의 회전각은 증가하여 보다 많은 공기의 흐름을 발생시키는데 이때 비접촉식 각도 센서(150)가 그 회전각을 센싱하여 ECU(130)로 전달함으로써 정확한 제어 및 불량을 판단할 수 있게 한다.In general, the operation signal is output at the duty ratio from the ECU 130, and as the value is higher, the rotation angle of the rotary type electronic idle speed control actuator increases to generate more air flow, and the non-contact angle sensor 150 rotates the rotation. Sensing the angle and passing it to the ECU 130 enables accurate control and failure determination.

비접촉식 각도 센서(150)는 일반적으로 홀센서를 많이 사용하며 자장의 변화에 따라 그 출력값이 변화하는데 이 전자식 아이들 스피드 콘트롤 액츄에이터는 내부에 영구자석(120)의 회전으로 인한 자장의 변화를 센싱하여 밸브(88)의 동작을 센싱할 수 있게 된다.The non-contact angle sensor 150 generally uses a lot of hall sensors and its output value changes according to the change of the magnetic field. The electronic idle speed control actuator senses the change of the magnetic field due to the rotation of the permanent magnet 120 inside the valve. The operation of 88 can be sensed.

ECU(130)는 비접촉식 각도 센서(150)의 출력을 받아 전자식 아이들 스피드 콘트롤 액츄에이터(140)의 동작 신호를 보정하여 변화시킬 수 있으며, 기계적인 불량을 판단하여 사용자에게 이를 전달할 수 있다.The ECU 130 may receive an output of the non-contact angle sensor 150 to correct and change an operation signal of the electronic idle speed control actuator 140, and determine a mechanical failure to transmit the same to a user.

상술한 바와같이, 본 발명에 따른 전자식 아이들 스피드 콘트롤 액츄에이터는 기계적인 동작을 센싱하여 제어하므로 정확한 제어로 연료 소비의 감소와 정확한 제어가 가능하게 되는 효과가 있다.As described above, since the electronic idle speed control actuator according to the present invention senses and controls a mechanical operation, it is possible to reduce fuel consumption and precise control by accurate control.

이상에서 설명한 것은 본 발명에 따른 전자식 아이들 스피드 콘트롤 액츄에이터를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자가라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is only one embodiment for implementing the electronic idle speed control actuator according to the present invention, and the present invention is not limited to the above-described embodiment, as claimed in the following claims. Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
