Abstract

PURPOSE: A shift lock system of a vehicle is provided to reduce manufacturing costs and to apply to most of vehicles by reducing the number of necessary components and simplifying the structure. CONSTITUTION: A shift lock system of a vehicle consists of an ignition switch(110), a brake lamp switch(120), a start lock relay(130), an oil pressure switch(140), a first and a second diode(D1,D2). The ignition switch turns on an engine start relay(SR) to drive a start motor(M). The brake lamp switch feeds a light-on signal to a brake lamp(BL) when a brake pedal is stepped on. The start lock relay is operated by the light-on signal of the brake lamp switch to shut/close a signal line between the ignition switch and the engine start relay. The oil pressure switch is operates depending on changes in pressure of engine oil to open/shut a signal line between the brake lamp switch and the start lock relay. The oil pressure switch is used to check the engine oil in most vehicles. The first and the second diode prevent an electric current from flowing back between the brake lamp switch and the start lock relay or between the oil pressure switch and the oil lamp. Therefore, the shift lock system prevents a vehicle from sudden start and sudden acceleration by starting an engine when a driver steps on the brake pedal.

Description

차량의 급발진 방지장치 {APPARATUS FOR PREVENTING SUDDEN DEPARTURE OF AUTOMOBILE}Vehicle start prevention device {APPARATUS FOR PREVENTING SUDDEN DEPARTURE OF AUTOMOBILE}

본 발명은 차량의 급발진 방지장치에 관한 것으로, 보다 상세하게는 부품수를 절감하고 제조비용을 절감할 수 있는 차량의 급발진 방지장치에 관한 것이다.The present invention relates to a sudden start prevention device for a vehicle, and more particularly, to a sudden start prevention device for a vehicle that can reduce the number of parts and manufacturing cost.

일반적으로, 차량은 운전자가 엔진을 시동한 다음 가속페달을 밟으면, 운전자가 가속페달을 밟은 답력에 상응하는 동력이 엔진에서 발생되어 차량을 주행시키도록 되어 있다.In general, when the driver starts the engine and then presses the accelerator pedal, power corresponding to the pedal force of the driver pressing the accelerator pedal is generated by the engine to drive the vehicle.

그런데, 차량의 엔진 및 변속기를 비롯한 주요 구성부에 많은 수의 전자제어장치가 사용되면서, 특히 자동변속기를 장착한 차량에서 정확한 원인을 추정할 수 없는 급발진사고가 빈번하게 발생되고 있다.However, as a large number of electronic control devices are used in major components including engines and transmissions of vehicles, particularly sudden occurrences of accidents in which vehicles cannot be precisely estimated can be estimated, especially in vehicles equipped with automatic transmissions.

이에 따라, 근래에 들어 상기한 차량의 급발진 사고를 미연에 방지하기 위한 급발진 방지장치에 대한 연구가 활발히 진행되고 있으며, 이중 상용화된 급발진 방지장치 중 자동변속기의 기어레버가 주차위치(Parking Range; "P" Range)에 있을 때 브레이크를 밟지 않으면 자동변속기의 기어레버가 주행위치(Drive Range; "D" Range)로 쉬프트업(Shift Up)되지 않도록 기어레버를 구속하는 쉬프트록방식의 급발진 방지장치가 있다.Accordingly, in recent years, research has been actively conducted on the sudden start prevention device for preventing the sudden start accident of the vehicle. Among the commercially available sudden start prevention devices, the gear lever of the automatic transmission is parked. If the brake is not applied when in the "P" range, a shift lock-type sudden start prevention device that restrains the gear lever so that the gear lever of the automatic transmission does not shift up to the drive range ("D" range) is provided. have.

상기한 바와 같은 쉬프트록(Shift Lock)방식의 급발진 방지장치는, 도 1에 도시된 바와 같이, 운전자의 키조작에 따라 스위칭동작되어 엔진시동용 릴레이(SR)를 온시킴으로써 시동모터(M)를 동작시키는 이그니션 스위치(Ignition Switch; 10)와, 자동변속기의 기어레버가 주차위치(P)에 있는지의 여부를 감지하여 그에 상응하는 감지신호를 발생하는 P-포지션스위치(20)와, 브레이크페달이 온되면 그에 따라 브레이크램프(BL)로 램프점등신호를 인가하는 브레이크램프스위치(30)를 포함하여 구성된다.As shown in FIG. 1, the sudden lock prevention device of the shift lock type as described above is switched according to the driver's key operation to turn on the starter motor M by turning on the engine start relay SR. An ignition switch 10 for operation, a P-position switch 20 for detecting whether the gear lever of the automatic transmission is in the parking position P and generating a corresponding detection signal, and a brake pedal On, it is configured to include a brake lamp switch 30 for applying a lamp lighting signal to the brake lamp (BL) accordingly.

또한, 상기한 급발진 방지장치는, 이그니션 스위치(10)로부터 "IG1" 또는 "ACC 단자를 통해 전원을 인가받아 동작되며, P-포지션스위치(20)로부터 입력되는 감지신호 및 브레이크램프스위치(30)로부터 입력되는 램프점등신호에 따라 자동변속기의 기어레버를 쉬프트록시키거나 쉬프트록을 해제하기 위한 제어신호를 출력하는 쉬프트록제어유닛(40) 및, 이 쉬프트록제어유닛(40)으로부터 출력되는 제어신호에 따라 동작하여 자동변속기의 기어레버의 진행을 구속하거나 그 구속을 해제하는 기어레버구속용 액츄에이터(50)로 구성된다.In addition, the sudden oscillation prevention device is operated by being supplied with power through the "IG1" or "ACC terminal from the ignition switch 10, the detection signal and the brake lamp switch 30 input from the P-position switch 20 A shift lock control unit 40 for outputting a control signal for shifting the gear lever of the automatic transmission or releasing the shift lock in accordance with a ramp-on signal input from the control unit; and a control output from the shift lock control unit 40. It is composed of a gear lever restriction actuator 50 for operating in response to the signal to restrain or release the restraining of the gear lever of the automatic transmission.

상기한 바와 같이 구성된, 쉬프트록 방식의 급발진 방지장치는, 이그니션스위치(10)가 "IG1" 또는 "ACC"위치에 있으면, 이그니션스위치(10)로부터 쉬프트록제어유닛(40)으로 전원이 인가되어 쉬프트록제어유닛(40)이 동작된다.In the shift lock type oscillation prevention device configured as described above, when the ignition switch 10 is in the " IG1 " or " ACC " position, power is supplied from the ignition switch 10 to the shift lock control unit 40. The shift lock control unit 40 is operated.

이때, P-포지션스위치(20) 및 브레이크램프스위치(30)가 "온"상태일 때는 쉬프트록제어유닛(40)으로부터 기어레버구속용 액츄에이터(50)로 쉬프트록을 해제하는 제어신호가 출력되어 기어레버구속용 액츄에이터(50)가 자동변속기의 기어레버에 대한 구속을 해제하여, 운전자가 자유롭게 자동변속기의 기어레버를 조작할 수 있도록 되어 있다.At this time, when the P-position switch 20 and the brake lamp switch 30 are in the "on" state, a control signal for releasing the shift lock from the shift lock control unit 40 to the gear lever restraining actuator 50 is output. The gear lever restricting actuator 50 releases the restraint on the gear lever of the automatic transmission, so that the driver can freely operate the gear lever of the automatic transmission.

이에 반해, P-포지션스위치(20)가 "온"인 상태에서, 브레이크램프스위치(30)가 "오프"상태일 경우에는 쉬프트록제어유닛(40)으로부터 기어레버구속용 액츄에이터(50)로 쉬프트록신호가 출력되어 기어레버구속용 액츄에이터(50)가 자동변속기의 기어레버를 쉬프트업되지 않도록 구속하므로, 운전자가 브레이크페달을 밟지 않은 상태에서는 자동변속기의 기어레버가 주차위치("P" Range)에서 주행위치("D" Range)로 쉬프트업되지 않는다.On the contrary, when the brake lamp switch 30 is in the "off" state with the P-position switch 20 in the "on" state, the shift from the shift lock control unit 40 to the gear lever restricting actuator 50 is performed. The lock signal is output and the gear lever restraint actuator 50 restrains the gear lever of the automatic transmission so that it does not shift up. Is not shifted up to the driving position ("D" range).

그러나, 상기한 바와 같은 종래의 급발진 방지장치는, 자동변속기의 기어레버에 대한 위치를 감지하는 스위치와 쉬프트록제어유닛(대개 마이크로컴퓨터를 사용함) 및 자동변속기의 기어레버를 구속하는 기어레버구속용 액츄에이터 등 비교적고가의 부품 들이 다수개 사용되었기 때문에, 구조가 복잡하고 그 제조비용이 비교적 고가임에 따라 널리 보급되지 못하는 문제점이 있었다.However, the conventional rapid start prevention device as described above is for a gear lever restraint for restraining a switch, a shift lock control unit (usually using a microcomputer), and a gear lever of an automatic transmission, for detecting a position of a gear lever of an automatic transmission. Since many expensive components such as actuators are used, there is a problem in that the structure is complicated and its manufacturing cost is relatively expensive, so it is not widely spread.

따라서, 본 발명은 상기한 바와 같은 종래기술의 문제점을 해결하기 위해 안출한 것으로, 급발진 방지장치의 부품수를 절감하고 구조를 단순화시켜 제조비용을 절감함으로써, 대부분의 차량에 널리 보급될 수 있는 차량의 급발진 방지장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention has been made to solve the problems of the prior art as described above, by reducing the number of parts of the rapid start and prevention device and simplify the structure to reduce the manufacturing cost, the vehicle that can be widely spread in most vehicles The object of the present invention is to provide a sudden oscillation prevention device.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 바람직한 실시예에 따른 차량의 급발진 방지장치를 도시한 개략적인 회로구성도로서, 동도면을 참조하면 알 수 있듯이, 본 발명에 따른 차량의 급발진 방지장치는, 이그니션스위치(110)와 브레이크램프스위치(120)와 시동잠금용 릴레이(130)와 오일압력스위치(140)와 제1 및 제2 다이오드(D1, D2)로 구성된다.FIG. 2 is a schematic circuit diagram illustrating a sudden start prevention device for a vehicle according to an exemplary embodiment of the present invention. As can be seen from the same drawing, the sudden start prevention device for a vehicle according to the present invention includes an ignition switch 110. ) And the brake lamp switch 120, the start lock relay 130, the oil pressure switch 140, and the first and second diodes D1 and D2.

상기 이그니션스위치(110)는 운전자의 키조작에 따라 스위칭동작되어 엔진시동용 릴레이(SR)를 온시킴으로써 시동모터(M)를 동작시키며, 상기 브레이크램프스위치(120)는 브레이크페달이 온되면 그에 따라 브레이크램프(BL)로 램프점등신호를 인가한다.The ignition switch 110 is switched according to the driver's key operation to operate the starting motor M by turning on the engine start relay SR, and the brake lamp switch 120 accordingly turns on when the brake pedal is turned on. The lamp lighting signal is applied to the brake lamp BL.

그리고, 상기 시동잠금용 릴레이(130)는 상기 브레이크램프스위치(120)로부터 인가되는 램프점등신호에 의해 스위칭절환되어 이그니션스위치(110)와 엔진시동용 릴레이(SR) 간의 신호라인을 개폐한다.In addition, the start lock relay 130 is switched by a lamp lighting signal applied from the brake lamp switch 120 to open and close a signal line between the ignition switch 110 and the engine start relay SR.

또한, 상기 오일압력스위치(140)는 엔진오일의 압력변화에 반응하여 스위칭절환되며, 오일램프를 점등 또는 소등함과 더불어 브레이크램프스위치(120)와 시동잠금용 릴레이(130)의 신호라인을 개폐한다. 참고로, 상기 오일압력스위치(140)는 대부분의 차량에서 엔진오일의 상태를 점검하기 위해 설치하는 것으로, 스위치 자체는 주지관용의 기술임을 밝혀둔다.In addition, the oil pressure switch 140 is switched in response to the change in the pressure of the engine oil, and turns on or off the oil lamp, and opens and closes the signal lines of the brake lamp switch 120 and the start lock relay 130. do. For reference, the oil pressure switch 140 is installed to check the state of the engine oil in most vehicles, it turns out that the switch itself is a technology for the main pipe.

한편, 제1 및 제2 다이오드(D1, D2)는 브레이크램프스위치(120)와 시동잠금용 릴레이(130)와 오일압력스위치(140) 및 오일램프 간에 전류가 역류되는 것을 방지하기 위해 설치된다.On the other hand, the first and second diodes (D1, D2) are installed to prevent the current flow back between the brake lamp switch 120, the start lock relay 130, the oil pressure switch 140 and the oil lamp.

상기한 바와 같이 구성된 본 발명의 작용효과를 도 2를 참조하여 설명하기로 한다.Effects of the present invention configured as described above will be described with reference to FIG.

브레이크페달을 밟지 않은 상태에서는, 브레이크램프스위치(120)가 오프되어 있는 상태이고 이로 인해 시동잠금용 릴레이(130) 역시 오프된 상태를 유지한다.In a state in which the brake pedal is not pressed, the brake lamp switch 120 is turned off, and thus the start lock relay 130 also stays off.

이때는, 운전자가 시동키를 시동위치(ST)로 조작하더라도 시동잠금용 릴레이(130)가 오프되어 있는 상태이므로, 이그니션스위치(110)로부터의 엔진시동신호가 엔진시동용 릴레이(SR)로 전달되지 않는 바, 시동모터(M)는 구동되지 않는다.At this time, even if the driver operates the start key to the start position ST, the start lock relay 130 is turned off, so that the engine start signal from the ignition switch 110 is not transmitted to the engine start relay SR. If not, the starting motor (M) is not driven.

반면, 운전자가 브레이크페달을 밟으면, 브레이크램프스위치(120)가 온되고, 브레이크램프스위치(120)로부터 램프점등신호가 출력되어 브레이크램프(BL)가 점등됨과 동시에 시동잠금용 릴레이(130)가 온된다. 여기서, 오일압력스위치(140)는 엔진오일의 압력에 변화가 없는 상태이므로, 온상태를 유지한다.On the other hand, when the driver presses the brake pedal, the brake lamp switch 120 is turned on, and a lamp lighting signal is output from the brake lamp switch 120 so that the brake lamp BL is turned on and the start lock relay 130 is turned on. do. Here, the oil pressure switch 140 maintains the on state because there is no change in the pressure of the engine oil.

이때, 운전자가 시동키를 시동위치(ST)로 조작하면, 이그니션스위치(110)로부터 출력된 엔진시동신호가 시동잠금용 릴레이(130)를 매개로 엔진시동용 릴레이(SR)로 인가된다.At this time, when the driver operates the start key to the start position ST, the engine start signal output from the ignition switch 110 is applied to the engine start relay SR through the start lock relay 130.

상기 이그니션스위치(110)로부터 인가된 엔진시동신호에 따라 엔진시동용 릴레이(SR)가 온되며, 이 엔진시동용 릴레이(SR)를 매개로 시동모터(M)에 직류전원(VCC)이 인가되어, 시동모터(M)가 구동된다.The engine start relay SR is turned on according to the engine start signal applied from the ignition switch 110, and a DC power supply VCC is applied to the starter motor M through the engine start relay SR. , The starting motor (M) is driven.

상기 시동모터(M)가 구동되어 엔진이 시동되면, 엔진의 내부로 엔진오일이 순환됨에 따라 엔진 내부에서 엔진오일의 압력이 변화되고, 이 변화된 엔진오일의 압력에 응답하여 오일압력스위치(140)가 오프된다.When the starting motor (M) is driven to start the engine, as the engine oil is circulated into the engine, the pressure of the engine oil changes in the engine, and the oil pressure switch 140 in response to the changed pressure of the engine oil. Is off.

엔진의 시동이 걸린 이후에는 상기와 같이 오일압력스위치(140)가 오프됨에 따라, 브레이크램프스위치(120)와 시동잠금용 릴레이(130)의 신호라인이 개방되기 때문에, 운전자가 브레이크페달을 밟아 브레이크램프스위치(120)가 온되더라도 시동잠금용 릴레이(130)는 스위칭동작되지 않는다.After the engine is started, as the oil pressure switch 140 is turned off as described above, since the signal lines of the brake lamp switch 120 and the start lock relay 130 are opened, the driver steps on the brake pedal. Even when the lamp switch 120 is turned on, the start lock relay 130 is not switched.

즉, 오일압력스위치(140)는 엔진이 시동된 이후에 시동잠금용 릴레이(130)가 불필요하게 스위칭동작되는 것을 방지하기 위해 설치된 것이다.That is, the oil pressure switch 140 is installed to prevent the start lock relay 130 from being unnecessarily switched after the engine is started.

상술한 바와 같이 본 발명은, 운전자가 브레이크페달을 밟은 상태에서만 엔진이 시동됨으로써, 시동시 엔진에서 발생되는 동력이 비정상적으로 높아지는 경우에 차량이 급발진하는 것을 방지하게 된다.As described above, according to the present invention, the engine is started only when the driver presses the brake pedal, thereby preventing the vehicle from suddenly starting when the power generated by the engine is abnormally increased.

상술한 바와 같이 본 발명에 따르면, 종래의 급발진 방지장치에 사용하였던 자동변속기의 기어레버 위치를 감지하는 스위치와 쉬프트록제어유닛 및 자동변속기의 기어레버를 구속하는 액츄에이터 등의 부품을 사용하지 않고도 차량의 급발진을 방지할 수 있게 되어 있음으로써(오일압력스위치는 일반적인 차량에서 엔진오일체크용으로 사용되고 있는 기존의 부품임), 구조를 단순화하고 제조비용을 절감할 수 있는 효과가 있다.As described above, according to the present invention, a vehicle without using a switch for detecting a gear lever position of an automatic transmission and a actuator for restraining a gear lever of an automatic transmission and a shift lever for detecting a gear lever position used in a conventional sudden start prevention device, It is possible to prevent sudden start-up (the oil pressure switch is an existing component used for engine oil check in a general vehicle), thereby simplifying the structure and reducing the manufacturing cost.

또한, 본 발명에 따르면, 브레이크를 밟지 않으면 이그니션스위치로부터 엔진시동용 릴레이로 인가되는 신호를 차단하여 차량의 급발진을 방지하도록 구성되어 있는 것이기 때문에, 자동변속기 차량뿐만 아니라 수동변속기의 차량에도 적용할 수 있는 효과가 있다.In addition, according to the present invention, since it is configured to block the signal applied to the engine start relay from the ignition switch when the brake is not applied, it can be applied to a vehicle of a manual transmission as well as an automatic transmission vehicle. It has an effect.
