Description

과속방지턱 감지 차량 제어 시스템{System for controlling vehicle and detecting a speed bump}System for controlling vehicle and detecting a speed bump}

본 발명은 과속방지턱 감지 차량 제어 시스템에 관한 것으로, 더욱 상세하게는 과속방지턱을 미리 감지하여 과속방지턱에 도달하기 직전에 차량의 서스펜션이 구동되도록 제어함으로써 차량의 승차감을 향상시키는 기술에 관한 것이다.The present invention relates to a speed bump detection vehicle control system, and more particularly, to a technique for improving the ride comfort of a vehicle by detecting the speed bump in advance and controlling the suspension of the vehicle to be driven immediately before reaching the speed bump.

일반적으로, 과속방지턱은 학교앞이나 유치원, 어린이 놀이터, 마을 통과지점 등 차량의 속도를 저속으로 규제할 필요가 있는 구간과 근린상업시설, 병원 등 차량이 많이 출입하는 구간 및 보도와 차도의 구분이 없는 도로로서 보행자가 많거나 어린이의 놀이로 교통사고의 위험이 있다고 판단되는 도로에 설치되어 주행중인 차량의 과속을 방지함으로써 안전사고가 발생되는 것을 방지하도록 되어 있다.In general, speed bumps are divided into sections that need to regulate the speed of vehicles at low speeds, such as in front of schools, kindergartens, children's playgrounds, and village passages, and areas where many vehicles enter and exit, such as neighboring commercial facilities and hospitals. As a road with no pedestrians or children playing, it is installed on a road that is considered to be a danger of traffic accidents.

이러한 과속방지턱 등을 부드럽게 통과하기 위해 자동차에 현가장치를 구비하는데, 현가장치는 차축과 연결하여 차량의 주행중에 노면으로부터 받는 진동이나 충격을 자동차 차체에 직접적으로 전달되지 않도록 제어하여 차체, 승객, 화물 등에 손상을 주지 않도록 하고 차량의 승차감을 좋게 만드는 장치이다.Suspension system is provided on the vehicle to smoothly pass such speed bumps, etc. The suspension system is connected to the axle to control the vehicle body, passenger, cargo by controlling the vibration or shock received from the road while driving the vehicle. It is a device that does not damage the back and makes the vehicle comfortable.

이러한 현가장치는 노면으로부터 충격을 완화시키는 섀시 스프링, 섀시 스프링의 자유진동을제어하여 승차감을 좋게 하는 쇽업소버, 차량의 롤링을 방지하는 스태빌라이저 바 등으로 구성된다.The suspension device is composed of a chassis spring to mitigate the impact from the road surface, a shock absorber to control the free vibration of the chassis spring to improve the ride comfort, a stabilizer bar to prevent rolling of the vehicle.

이중에서 쇽업소버는 자동차의 주행중 스프링이 받는 충격에 의해 발생하는 고유진동을 흡수하여 진동을 빨리 감쇠시켜 승차감을 좋게 하기 위해 차체와 휠 사이에 장착되어 있다.In particular, the shock absorber is installed between the vehicle body and the wheel to absorb the natural vibration generated by the shock of the spring while driving the vehicle, to quickly attenuate the vibration to improve the riding comfort.

이와같은 쇽업소버와 함께 에어 스프링이 장착된 전자제어 서스펜션장치(ECS;electronic control suspension system)가 사용되어 노면으로부터의 진동을 제거하기 위한 방향으로 액츄에이터를 제어함으로써 승차감의 향상을 도모해왔다.Along with this shock absorber, an electronic spring suspension (ECS) equipped with an air spring has been used to improve ride comfort by controlling the actuator in a direction to remove vibration from the road surface.

그러나, 종래의 전자제어 서스펜션장치는 과속방지턱을 넘어서는 순간 서스펜션 및 댐핑제어를 시행함에 따라 노면으로부터의 진동 제거가 미흡한 경우가 많았다.However, in the conventional electronically controlled suspension device, in many cases, the removal of vibration from the road surface is insufficient as the suspension and damping control is performed at the moment beyond the speed bumps.

특히, 운전자가 과속방지턱을 인식하지 못하고 빠른 속도로 과속방지턱을 넘게 되면 전자제어 서스펜션장치의 서스펜션 기능이 더 약화되어 승차감이 현저히 낮아지는 문제점이 있었다.In particular, when the driver does not recognize the speed bumps and passes the speed bumps at a high speed, the suspension function of the electronically controlled suspension device is further weakened, resulting in a significantly lower riding comfort.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 전방의 과속방지턱을 감지하여 차량속도를 감속시키고 과속 방지턱에 도달하기까지 걸리는 시간을 계산하여 과속 방지턱에 도달하기 직전에 서스펜션을 수행하도록 함으로써 차량의 안정성을 확보하고 탑승자의 승차감을 향상시키도록 하는데 그 목적이 있다.The present invention has been made to solve the above problems, by detecting the speed bump in front of the vehicle to decelerate the vehicle speed and calculate the time it takes to reach the speed bump to perform the suspension just before reaching the speed bump The purpose is to ensure the stability of the vehicle and to improve the ride comfort of the occupants.

도 1은 본 발명의 실시예에 따른 과속방지턱 감지 차량 제어 시스템의 구성도이다.1 is a block diagram of a speed bump prevention vehicle control system according to an embodiment of the present invention.

과속방지턱 감지 차량 제어 시스템은 과속방지턱 감지부(100), 제어부(200), 브레이크(300) 및 서스펜션 제어부(400)를 구비한다.The speed bump detection vehicle control system includes a speed bump detection unit 100, a control unit 200, a brake 300, and a suspension control unit 400.

과속방지턱 감지부(100)는 차량 전방의 과속방지턱을 감지하여 그 감지결과를 제어부(200)로 전달한다. 이때, 과속방지턱 감지부(100)는 카메라를 구비하여 전방의 과속방지턱을 촬영하고 그 촬영결과를 제어부(200)에 전달하도록 한다. 한편, 과속방지턱 감지부(100)는 네비게이션(미도시)을 포함하여 네비게이션(미도시)으로부터 과속방지턱 정보를 수신하면 이를 제어부(200)에 전달하도록 구현할 수도 있다. 또한, 과속방지턱 감지부(100)는 레이더(미도시)를 포함할 수 있다.The speed bumps detecting unit 100 detects the speed bumps in front of the vehicle and transmits the detection result to the control unit 200. At this time, the speed bumps detection unit 100 is provided with a camera to shoot the speed bumps in the front and transmit the photographing results to the control unit 200. On the other hand, the speed bump detection unit 100 may include a navigation (not shown) to receive the speed bump information from the navigation (not shown) to deliver it to the control unit 200. In addition, the speed bumps detection unit 100 may include a radar (not shown).

또한, 과속방지턱 감지부(100)는 차량이 차선을 이탈하는 경우 이를 감지하고 해당 속도에서 목적 차선을 따라가도록 운전자를 돕기 위한 차선유지보조시스템(Lane Keeping Assist System:LKAS)에 구비되는 카메라를 공유할 수도 있다.In addition, the speed bump detection unit 100 shares a camera provided in a Lane Keeping Assist System (LKAS) for detecting a vehicle leaving a lane and assisting a driver to follow a target lane at a corresponding speed. You may.

제어부(200)는 ECU(Engine control unit) 등을 포함하며, 과속방지턱 감지부(100)로부터 과속방지턱 감지 결과를 수신하면, 차속정보를 이용하여 차량의 현재 차속이 기준치 이상인지를 판단하고, 차량의 현재 차속이 기준치 이상이면 브레이크(300)로부터 브레이크 페달 작동여부를 판단하여 브레이크 페달이 작동되고 있지 않으면 자동 감속을 수행한다. 이때, 제어부(200)는 변속제어기(transmission control unit;TCU;미도시), 차속센서(미도시) 등을 통해 차속정보를 얻을 수 있다.The controller 200 includes an engine control unit (ECU) and the like, and upon receiving the speed bump detection result from the speed bump detector 100, determines whether the current vehicle speed of the vehicle is greater than or equal to the reference value by using the vehicle speed information. If the current vehicle speed is equal to or more than the reference value determines whether the brake pedal is operated from the brake 300, and if the brake pedal is not operated, the automatic deceleration is performed. In this case, the controller 200 may obtain vehicle speed information through a transmission control unit (TCU; not shown), a vehicle speed sensor (not shown), or the like.

서스펜션 제어부(400)는 ECS(electronic control suspension system)를 포함하며, 제어부(200)로부터 서스펜션 제어 요청을 받으면 차량의 서스펜션을 제어한다. 이때, 서스펜센 제어는 차체 중량을 지지함과 동시에 노면 불규칙 등에 의한 차륜의 상하진동을 완화하고 흡수하여 진동이 차체에 직접 전달되지 않도록 제어하는 것을 의미한다.The suspension control unit 400 includes an electronic control suspension system (ECS), and when the suspension control request is received from the control unit 200, the suspension control unit 400 controls the suspension of the vehicle. At this time, the suspense control means to support the weight of the vehicle body and at the same time to mitigate and absorb the up and down vibration of the wheel due to irregular road surface, so that the vibration is not transmitted directly to the vehicle body.

이하, 도 2를 참조하여, 본 발명의 실시예에 따른 과속방지턱 감지 차량 제어 방법을 구체적으로 설명하기로 한다.Hereinafter, a method for controlling the speed bumps according to an exemplary embodiment of the present invention will be described in detail with reference to FIG. 2.

먼저, 과속방지턱 감지부(100)가 차량 주행중에 전방의 과속방지턱을 감지하는 경우, 제어부(200)는 차량의 현재 차속이 기준 차속 이상인지를 판단한다(S102).First, when the speed bumps detecting unit 100 detects the speed bumps in front of the vehicle while driving, the control unit 200 determines whether the current vehicle speed of the vehicle is greater than or equal to the reference vehicle speed (S102).

상기 과정 S102의 판단 결과, 제어부(200)는 차량의 현재 차속이 기준 차속 이상이면 브레이크 페달의 작동여부를 판단하여(S103), 브레이크 페달이 작동되지 않고 있으면 감속하고 있지 않은 것으로 판단한다. 이에, 제어부(200)는 브레이크(300)를 제어하여 차량을 자동 감속시킨다(S104). 한편, 제어부(200)는 차량의 현재 차속이 기준 차속 이하이거나 브레이크 페달이 동작중인 경우 운전자가 과속방지턱을 인식하고 감속을 시도하고 있는 것으로 판단하고 아래 과정 S105로 넘어간다.As a result of the determination of step S102, the controller 200 determines whether the brake pedal is operated when the current vehicle speed of the vehicle is equal to or higher than the reference vehicle speed (S103), and determines that the brake pedal is not decelerated if it is not operated. Accordingly, the controller 200 controls the brake 300 to automatically decelerate the vehicle (S104). On the other hand, if the current vehicle speed of the vehicle is less than the reference vehicle speed or the brake pedal is in operation, the controller 200 determines that the driver recognizes the speed bump and attempts to decelerate, and then proceeds to step S105.

그 후, 제어부(200)는 과속방지턱과의 거리를 계산하여 과속 방지턱 통과시점을 계산한다(S105). 이때, 차량의 앞바퀴와 과속방지턱 사이의 거리를 계산하여 앞 바퀴가 과속 방지턱에 도달하는 시점을 계산한다. 이때, 제어부(200)는 카메라(미도시), GPS 장치(미도시) 또는 네비게이션장치(미도시), 레이더(미도시)의 출력을 통해 과속방지턱과의 거리를 계산할 수 있으며, 그 거리로부터 시간을 도출하여 과속방지턱에 차량의 앞바퀴가 도달하는 시점을 계산하도록 한다. Thereafter, the controller 200 calculates the distance between the speed bumps and calculates the time point for passing the speed bumps (S105). At this time, by calculating the distance between the front wheel and the speed bump of the vehicle to calculate the time when the front wheel reaches the speed bump. In this case, the controller 200 may calculate a distance from the speed bump through the output of a camera (not shown), a GPS device (not shown) or a navigation device (not shown), and a radar (not shown), and the time from the distance To calculate the time to reach the front wheel of the vehicle to the speed bumps.

제어부(200)는 과속 방지턱에 도달하는 시점 계산결과를 서스펜션 제어부(400)로 전달하여, 서스펜션 제어부(400)가 과속 방지턱에 도달하는 시점에 서스펜션 제어를 수행하도록 한다(S106). 즉, 서스펜션 제어부(400)는 과속 방지턱에 도달하는 시점에 자동차의 높이와 현가특성(스프링정수 및 감쇠력)을 조절하여 차체가 노면에 긁히지 않도록 차페를 높이고 과속 방지턱을 통과하면 주행 안전성을 위해 차체를 낮춰준다. 또한, 서스펜션 제어부(400)는 과속 방지턱을 부드럽게 통과하기 위해 현가 장치를 매 순간마다 강하게(HARD) 또는 부드럽게(SOFT) 조절한다.The control unit 200 transmits the calculation result of the time point at which the speed bumps are reached to the suspension control unit 400 so that the suspension control unit 400 performs the suspension control at the time point at which the speed bumps are reached (S106). That is, the suspension control unit 400 adjusts the height and suspension characteristics (spring constant and damping force) of the vehicle at the time of reaching the speed bump so that the car body is not scratched on the road surface and passes the speed bump so that the vehicle body can be moved for safety. Lower it. In addition, the suspension controller 400 adjusts the suspension device HARD or SOFT at every moment to smoothly pass the speed bumps.

그 후, 제어부(200)는 차량이 과속방지턱을 통과하였는지를 판단하고(S107), 통과한 경우 종료한다. Thereafter, the controller 200 determines whether the vehicle has passed the speed bumps (S107), and terminates when the vehicle has passed.

상기와 같이, 본 발명은 과속방지턱을 미리 감지하고 과속방지턱과의 거리를 계산하여 차속 및 서스펜션제어를 미리 시행할 수 있도록 함으로써 차량 주행 안정성이 향상된다. As described above, the present invention improves the vehicle driving stability by detecting the speed bump in advance and calculating the distance to the speed bump so that the vehicle speed and the suspension control can be performed in advance.
