본 발명은 자동차의 에이비에스 작동시 동력조향장치의 작동을 초기화시키는 장치에 관한 것으로, 특히 에이비에스 시스템을 갖춘 자동차가 마찰계수가 낮은 노면의 주행하다 제동을 할 때 동력조향장치를 강제로 리셋시켜 선회를 억제해 줌으로써 사고유발을 방지할 수 있도록 된 자동차의 에이비에스 작동시 동력조향불능장치에 관한 것이다.The present invention relates to a device for initiating the operation of the power steering device during the operation of the ABS of the vehicle, in particular, when the vehicle with the ABS system is forced to reset the power steering when braking while driving on the road with a low coefficient of friction The present invention relates to a power steering disabling device in the operation of the ABS of a vehicle that can prevent accidents by suppressing turning.

일반적으로 자동차에는 주행중에 주행방향을 운전자의 임의대로 바꿀 수 있도록 된 조향장치를 구비하고 있는 바, 이러한 조향장치에는 조작력을 배가시켜 조향시 운전자의 편의를 도모할 수 있도록 조작기구의 배력작용에 동력원이 되는 유압을 발생시키는 동력장치와, 이 동력장치에서 발생된 유압을 차륜의 조향력으로 변환시키는 작동장치 및, 조향을 위해 이 작동장치의 유로를 적절히 개폐시켜 주는 제어장치로 구성된 동력조향장치가 개발되어 있다.In general, a vehicle is provided with a steering device that can change the driving direction at the driver's discretion while driving, and the steering device is a power source for the operation of the power of the operation mechanism to double the operating force to facilitate the driver's convenience during steering. The power steering device is composed of a power device for generating a hydraulic pressure, an operating device for converting the hydraulic pressure generated by the power device into a steering force of the wheel, and a control device for properly opening and closing the flow path of the operating device for steering. It is.

또한 자동차에는 주행중에 차량의 속도를 줄이거나 완전정지를 목적으로 차체에 제동력을 발휘하기 위한 제동장치가 장착되어 있는 바, 이러한 제동장치중에서 근래에는 각 차륜에 장착된 스피드센서로부터 검출된 신호를 근거로 하여 각 차륜의 유압회로가 독립적으로 제어되어 제동중에도 조향이 운전자의 의지대로 가능한 에이비에스(ABS ; Anti-Lock Brake)제동장치가 개발되어 있다.In addition, the vehicle is equipped with a braking device for exerting a braking force on the vehicle body for the purpose of reducing the speed of the vehicle or completely stopping the vehicle while driving. Based on the signals detected from the speed sensor mounted on each wheel recently, Therefore, the brake system has been developed to control the hydraulic circuit of each wheel independently so that steering can be carried out at the driver's will during braking.

상기와 같은 동력조향장치와 에이비에스 제동장치는 각기 조향에 편리함과 제동의 안정성을 부여할 수 있어 운전자의 안전과 편의를 돕는데 기여하고 있는 실정이다.The power steering device and the ABS braking device as described above can provide convenience and braking stability to each steering, contributing to helping the driver's safety and convenience.

그런데 상기와 같은 동력조향장치와 에이비에스제동장치를 모두 다 장착한 차량이 마찰계수가 낮은 젖은 아스팔트나 방면에서 주행중 제동(에이비에스)을 하면서 조향을 의지대로 급격하게 하면, 차량의 안정성에 매우 위험한 조건이 되어 사고유발의 소지가 높은 문제점이 있었다.However, if a vehicle equipped with both the power steering device and the ABS braking device as described above suddenly steer the steering while braking (ABS) while driving on wet asphalt or a low friction coefficient, it is very dangerous to the stability of the vehicle. There was a high problem of accidents caused by the condition.

이에 본 발명은 상기한 같은 문제점을 해결하기 위해 안출된 것으로, 에이비에스 작동시간동안에는 동력조향장치를 리셋시켜 스티어링에포트(Steering Effort; 조향에 드는 힘)가 제어상의 최대치보다 더 무거워지도록 함으로써, 최적의 주행안정성을 보장하여 사고유발을 사전에 방지할 수 있도록 된 자동차의 에이비에스작동시 동력조향불능장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by resetting the power steering during the operation time of the ABS, so that the steering effort (steering force) is heavier than the maximum in the control, the optimum The purpose of the present invention is to provide a power steering disabling device in the operation of the ABS of a car, which can prevent accidents in advance by ensuring driving stability of the vehicle.

It is configured to lose.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 에이비에스 작동시 동력조향불능장치의 구성을 도시한 구성상태도이다.1 is a configuration diagram showing the configuration of the power steering disabling device during the operation of the ABS according to the present invention.

본 발명의 에이비에스 작동시 조향불능장치는 도면에 도시된 바와 같이, 동력조향을 제어하는 전자동력조향장치제어부(Electronic Power Steering Control Unit; 1)와 이에 연결된 전압조정기(2), 펄스폭변조기(Pulse Width Modulation; 3), 트랜지스터(4), 솔레노이드밸브(5)로 구성된 동력조향장치에 있어서, 상기 전자동력조향장치제어부(1)에 트랜지스터(6)와 오아게이트(7)를 매개로 에이비에스제어부(8)가 연결되어 구성된다.As shown in the drawing, the steering disable device during the operation of the present invention includes an electronic power steering control unit (Electronic Power Steering Control Unit) 1 for controlling power steering, a voltage regulator 2 connected thereto, and a pulse width modulator ( Pulse width modulation (3), transistor (4), solenoid valve (5) in the power steering device, the electromagnetic power steering device control unit (1) via the transistor 6 and the oragate (7) via the AV The control part 8 is connected and comprised.

여기서 상기 전자동력조향장치제어부(1)에는 트로틀포지션센서와 차속센서등으로 이루어진 기존의 전자동력조향장치용 입력신호(9)가 전달됨은 물론, 상기 에이비에스제어부(8)로부터는 솔레노이드동작신호와 모터동작신호를 오아케이트(7)와 트랜지스터(6)를 거쳐 입력받도록 되어 있다.Here, the electric power steering device control unit 1 transmits the input signal 9 for the conventional electric power steering device, which is composed of a throttle position sensor and a vehicle speed sensor, as well as the solenoid operation signal from the ABS control unit 8. The motor operation signal is inputted through the oak 7 and the transistor 6.

따라서, 상기 전자동력조향장치제어부(1)는 동력조향장치의 동작중에, 에이비에스제어부(8)에 솔레노이드동작신호와 모터동작신호중 어느 한 신호만 입력되면 이를 오아게이트(7)가 받아 트랜지스터(6)를 거쳐 받게 되는데, 이렇게 에이비에스제어부(8)로부터 전자동력조향장치제어부(1)에 신호가 보내지는 시간동안에는 즉 에이비에스가 작동하는 시간중에는 전자동력조향장치제어부(1)를 강제로 리셋시키게 되어 스티어링에포트가 제어상 최대치보다 더 무거워지게 된다.Therefore, when the solenoid operation signal and the motor operation signal are input to the AV controller 8 during the operation of the power steering device, the electromagnetic power steering device control unit 1 receives the OA gate 7 and the transistor 6 In this way, during the time when the signal is transmitted from the ABS control unit 8 to the fully-powered steering system control unit 1, that is, during the time when the ABS is operated, the electronic power steering system control unit 1 is forcibly reset. This makes the steering effort heavier than the maximum control.

즉, 상기 에이비에스제어부(8)가 에이비에스의 작동을 감지하면, 전자동력조향장치제어부(1)는 동력조향을 중단시켜 주행의 안정성을 확보할 수 있게 된다.That is, when the ABS control unit 8 detects the operation of the ABS, the electronic power steering control unit 1 can stop the power steering to ensure the stability of the driving.

이상 설명한 바와 같이 본 발명에 따른 자동차의 에이비에스작동시 동력조향불능장치에 의하면, 자동차가 마찰계수가 낮은 노면을 주행할 경우 에이비에스 작동시간 동안에는 동력조향장치가 리셋되어 스티어링에포트를 제어상의 최대치보다 더 무거워지게 함으로써, 최적의 주행안정성과 조타력을 보장하면서 사고유발을 사전에 예방할 수 있는 효과가 있게 된다.As described above, according to the power disabling device during the operation of the ABS of the vehicle according to the present invention, when the vehicle travels on a road surface having a low friction coefficient, the power steering is reset during the operation time of the ABS so that the maximum value of the steering support is controlled. By making it heavier, it is possible to prevent accidents in advance while ensuring optimal driving stability and steering power.
