Description
본 발명은 자동차의 안전 시스템 제어에 관한 것으로서, 점화 스위치가 온인 상태에서 엔진이 정지되어 재시동을 요구하는 경우 ICU(immobilizer cntrol unit)와 ECU(electronic control unit)통신 절차를 생략하여 신속한 엔진 시동을 확보하도록 한 자동차의 안전 시스템 제어 방법에 관한 것이다.The present invention relates to the control of a safety system of a vehicle. When the engine is stopped and the engine is restarted when the ignition switch is turned on, the engine is skipped and thus the engine is secured by omitting an ICU (immobilizer cntrol unit) and an electronic control unit (ECU) communication procedure. It relates to a method for controlling a safety system of a vehicle.
자동차에는 주행상태에 따라 강제로 작동을 해지 하거나 다른 기능으로 전환하는 등 안전 시스템이 이용되고 있다.Safety systems are being used in automobiles such as forcibly disabling or switching to other functions depending on driving conditions.
이중 ICU(immobilizer control unit)시스템은 점화 스위치를 온/오프할 때마다 ECU(electronic control unit)와 통신을 하여 키 스위치에서 키의 위치를 확인하는 2중 안전 구조로 이루어져 있다.The dual immobilizer control unit (ICU) system has a double safety structure that communicates with the electronic control unit (ECU) each time the ignition switch is turned on and off to determine the position of the key on the key switch.
그러나 점화 스위치가 온을 유지하는 시동 온 상태에서 운전자의 클러치 조작 미숙 또는 엔진 부분이 비정상적 동작에 따라 엔진이 정지되는 경우 운전자가 재시동을 걸기 위하여 키를 스타트 위치로 돌리면 ECU와 ICU간의 통신이 이루어지므로 차량의 정지 상태가 길어져 사고의 위험이 있다.However, when the engine is stopped due to the driver's clutch operation or the engine part stopped due to the abnormal operation of the engine while the ignition switch is on, when the driver turns the key to the start position to restart, communication between the ECU and the ICU is performed. There is a danger of an accident due to an extended vehicle stop.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 점화 스위치가 온이고 엔진이 정지된 상태에서 시동을 걸기 위한 시도가 발생하면 ECU와 ICU간의 통신 절차를 생략하여 시동이 빠르게 이루어질 수 있도록 하여 위험을 방지하는데 그 목적이 있다.The present invention has been made to solve the above problems, if an attempt is made to start the engine with the ignition switch on and the engine is stopped, the communication procedure between the ECU and the ICU can be omitted so that the startup can be performed quickly. The purpose is to avoid the danger.
상기한 목적을 달성하기 위하여 본 발명은 엔진의 동작 상태를 비교판단하는 제1단계와; 점화 스위치가 온접점에 위치되어 있는지를 비교판단하는 제2단계와; 점화 스위치가 온접점에 위치되어 있으면 재시동을 위하여 스타트 접점으로 트리거 되는지를 판단하는 제3단계와; 상기 제3단계에서 점화 스위치가 온접점을 유지하면 엔진 정지를 유지시키고 스타트 접점의 트리거를 검출하면 ICU와의 통신 절차를 생략한 후 인젝터와 점화 장치를 온하여 시동을 할 수 있도록 하는 제4단계로 이루어지는 것을 특징으로 한 다.In order to achieve the above object, the present invention includes a first step of comparing the operating state of the engine; A second step of judging whether the ignition switch is located at the on-contact point; Determining whether the ignition switch is triggered by the start contact for restarting if the ignition switch is located at the on-contact point; In the third step, if the ignition switch maintains the on-contact point, the engine stops, and if the trigger of the start contact is detected, the fourth step of allowing the injector and the ignition device to be started after starting the communication procedure with the ICU is omitted. It is characterized by that.
도 1은 본 발명을 실현하는 장치를 간략하게 나타낸 블록도이고, 도 2는 본 발명의 실시예에 따른 안전 시스템 제어 방법을 나타낸 순서도이다.1 is a block diagram schematically showing an apparatus for realizing the present invention, and FIG. 2 is a flowchart illustrating a safety system control method according to an embodiment of the present invention.
이하, 첨부된 도면을 참조로하여 본 발명의 가장 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention.
본 발명의 구성 및 동작을 도 1과 도2를 참고로하여 설명하면 다음과 같다.The configuration and operation of the present invention will be described with reference to FIGS. 1 and 2 as follows.
먼저 ECU(10)는 크랭크 위치 신호를 읽어들여 엔진이 정지 상태인가를 비교 판단한다(S100).The ECU 10 first reads the crank position signal and compares and determines whether the engine is stopped (S100).
S100에서 엔진이 동작중인 상태로 판단되면 계속 엔진이 동작할 수 있도록 인젝터(미도시)와 점화 장치(미도시)에 온신호를 출력한다(S430).If it is determined that the engine is in operation in step S100 to output the on signal to the injector (not shown) and the ignition device (not shown) so that the engine continues to operate (S430).
그러나, S100에서 엔진이 정지된 상태로 판단되면 키 스위치(30)로 부터 점화 스위치가 온접점에 위치하는가를 비교판단한다(S200).However, if it is determined in S100 that the engine is stopped, it is determined whether the ignition switch is located at the on-contact point from the key switch 30 (S200).
S200에서 점화 스위치가 온접점에 위치하지 않는 것으로 판단되면 ECU(10)와 ICU(20)의 통신 절차를 정상적으로 실행하고(S201), 점화 스위치가 온접점에 위치하는 것으로 판단되면 일단 비정상적인 경우에 해당하므로 ECU(10)와 ICU(20)간의 이전에 행해진 통신이 정상상태인가를 비교판단한다(S300).If it is determined in S200 that the ignition switch is not located at the on-contact point, the communication procedure between the ECU 10 and the ICU 20 is normally executed (S201), and if it is determined that the ignition switch is located at the on-contact point, it is abnormal. Therefore, it is determined whether the communication previously performed between the ECU 10 and the ICU 20 is in a normal state (S300).
S300에서 이전 통신이 정상적으로 행해지지 않았다면 다시 ECU(10)와 ICU(20)간의 통신을 재개하고(S201), 이전 통신이 정상적으로 행해졌다면 시동을 걸기 위한 시도가 발생하고 있는가를 판단하기 위하여 키 스위치(30)로 부터 키 위치가 스타트위치에 있는 가를 비교판단한다(S400).If the previous communication is not normally performed in S300 resumes communication between the ECU 10 and the ICU 20 again (S201), and if the previous communication is normally performed, the key switch 30 to determine whether an attempt to start up is occurring. Determine whether the key position is in the start position from the (S400).
S400에서 키 위치가 스타트위치에 있는 것으로 판단되면 빠른 시동을 위하여 ECU(10)와 ICU(20)간의 통신 절차를 생략하고(S420), 인젝터(미도시)와 점화 장치(미도시)에 온신호를 출력한다(S430).If it is determined in S400 that the key position is at the start position, the communication procedure between the ECU 10 and the ICU 20 is omitted for a quick start (S420), and the on-signal to the injector (not shown) and the ignition device (not shown) are provided. Outputs (S430).
그러나, S400에서 키 위치가 스타트 위치에 있는 것이 아니라면 주행상태에 따른 엔진 정지로 판단하여 엔진을 정지한다(S410).However, if the key position is not at the start position in S400, it is determined that the engine is stopped according to the driving state (S410).
따라서, 엔진이 정지되고 점화 스위치가 온접점에 위치할 때는 재시동을 걸기 위하여 키 위치가 스타트에 위치되면 ECU(10)와 ICU(20)간의 통신을 생략하고 인젝터(미도시)와 점화 장치(미도시)에 온 신호를 출력하므로써 엔진의 시동이 빠르게 이루어진다.Therefore, when the engine is stopped and the ignition switch is located at the on-contact point, the communication between the ECU 10 and the ICU 20 is omitted when the key position is positioned at the start to restart, and the injector (not shown) and the ignition device (not shown) The engine is started quickly by outputting the ON signal.
그러므로 점화 스위치가 온인상태에서 엔진이 정지되어 재시동을 요구하는 경우 ICU(20)와 ECU(10)통신 절차를 생략하므로써 신속한 엔진 시동을 확보할 수 있게 된다.Therefore, when the engine is stopped while the ignition switch is turned on and requires a restart, the engine can be quickly started by omitting the ICU 20 and ECU 10 communication procedures.
