Description
본 고안은 차량의 업힐(Up-Hill) 출발장치에 관한 것으로서, 보다 상세하게는 오르막길에서 정지 후 재출발시 차체가 뒤로 밀리는 것을 방지하는 차량의 업힐 출발장치에 관한 것이다.The present invention relates to an uphill start device of a vehicle, and more particularly, to an uphill start device of a vehicle that prevents the vehicle body from being pushed back when stopping and restarting on an uphill road.
일반적으로 차량을 정지시킨 후, 출발시에는 클러치를 작동시켜 변속단을 선택한 후, 브레이크의 작동을 해제하고 가속 페달을 작동시켜 출발하게 된다.In general, after the vehicle is stopped, the clutch is operated to select a shift stage by operating the clutch, and then the brake is released and the accelerator pedal is operated to start.
그러나 오르막길에서 정지 후 재출발하게 되면 브레이크의 해제와 가속 페달의 작동간의 시차에 의하여 짧으나마 가속 페달을 작동하지 않는 상태에서 브레이크가 해제되어 제동력이 해제되는 시간이 발생하게 된다.However, if the vehicle is restarted after stopping on an uphill road, the brake is released in a state in which the brake is released while the accelerator pedal is not operated due to the time difference between the release of the brake and the operation of the accelerator pedal.
따라서 차량의 차체의 중량에 작용하는 중력에 의하여 차체가 뒤로 밀리는 현상이 발생된다.Therefore, the phenomenon that the vehicle body is pushed back by the gravity acting on the weight of the vehicle body occurs.
그러나 상기와 같이 차체가 뒤로 밀리는 현상은 브레이크의 해제와 가속 페달의 작동시기를 적절히 조절할 수 있는 숙련도 높은 운전자에에 있어서는 감소 및 제거될 수 있으나 숙련도가 낮은 운전자에게 있어서는 오르막길 재출발을 상당히 곤란케 한다.However, the phenomenon that the vehicle body is pushed back as described above can be reduced and eliminated for the experienced driver who can properly adjust the release of the brake and the operation of the accelerator pedal, but it is very difficult for the experienced driver to restart uphill.
따라서 본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 오르막길에서 정지 후 재출발시에 차체가 뒤로 밀리는 것을 방지하여 오르막길 재출발을 용이하게 하는 수동변속기 차량의 업힐 출발장치를 제공하는 데 있다.Therefore, the present invention is devised to solve the above problems, an object of the present invention is to provide an uphill starting device for a manual transmission vehicle that prevents the vehicle body from being pushed back when the vehicle is restarted after stopping at an uphill road to facilitate the uphill restart. There is.
이를 실현하기 위하여 본 고안에 따른 차량의 업힐 출발장치는 브레이크 페달의 작동으로 마스터 실린더에서 발생된 유압을 브레이크로 공급 및 배출시키는 것을 단속하여 브레이크의 작동 및 해방을 제어하도록 마스터 실린더에서 브레이크로 공급하는 유압 라인에 설치된 밸브수단, 이 밸브수단을 제어하여 브레이크 페달의 해방과는 별도로 브레이크의 해방시기를 제어할 수 있도록 밸브수단으로 공급되는 전원을 운전자의 의도 및 가속 페달의 작동으로 제어하는 스위칭 수단을 포함한다.In order to realize this, the uphill starting device of a vehicle according to the present invention intermittently supplies and discharges hydraulic pressure generated in the master cylinder to the brake by the operation of the brake pedal to supply the brake from the master cylinder to control the operation and release of the brake. Valve means installed in the hydraulic line, switching means for controlling the valve means to control the power supply to the valve means to control the release time of the brake separately from the release of the brake pedal by the driver's intention and the operation of the accelerator pedal. Include.
상술한 바와 같이 구성된 차량의 업힐 출발장치는 운전자의 의도로 스위칭 수단을 작동시킴에 따라 밸브수단을 작동시켜 브레이크 페달의 해방과는 별도로 브레이크를 계속 작동시키고, 가속 페달을 작동시켜 스위칭 수단을 해제시킴에 따라 밸브수단을 작동시켜 브레이크를 해방시킨다.The uphill starting device of the vehicle configured as described above operates the valve means according to the driver's intention to continue operating the brake separately from the release of the brake pedal, and releases the switching means by operating the accelerator pedal. Release the brake by operating the valve means according to.
이하 본 고안의 바람직한 구성 및 작용을 첨부한 도면에 의거하여 보다 상세히 설명한다.Hereinafter, the preferred configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings.
도 1은 본 고안에 관련하여 차량의 업힐 출발장치 비작동 상태의 구성도.1 is a configuration of the uphill start device non-operational state of the vehicle according to the present invention.
도 2는 본 고안에 관련하여 차량의 업힐 출발장치 작동 상태의 구성도이다.Figure 2 is a block diagram of the operating state of the uphill starting device of the vehicle in accordance with the present invention.
도 1은 본 고안에 관련하는 차량의 업힐 출발장치 비작동 상태의 구성도로서, 브레이크 페달(1)의 작동으로 마스터 실린더(3)에서 유압을 발생시켜 브레이크(5,7)로 공급 및 배출시켜 브레이크(5,7)를 작동 및 해방시킬 수 있도록 구성되어 있다.1 is a configuration diagram of a non-operating state of an uphill starting device of a vehicle according to the present invention, by operating the brake pedal 1 to generate hydraulic pressure in the master cylinder 3 to supply and discharge the brakes 5 and 7. It is comprised so that brakes 5 and 7 can be operated and released.
즉, 브레이크 페달(1)과 마스터 실린더(3)사이에는 브레이크 페달(1)을 작은 조작력으로 작동시킬 수 있도록 부스터(9)가 설치되어 있다.That is, the booster 9 is provided between the brake pedal 1 and the master cylinder 3 so that the brake pedal 1 can be operated with a small operating force.
그리고 마스터 실린더(3)와 브레이크(5,7)사이에는 이들간의 유압 공급 및 배출을 가능케 하는 유압 라인(11,13)이 설치되어 있다. 브레이크(5,7)는 오르막길에서 제동성능을 향상시키기 위하여 프론트 브레이크 리어 브레이크로 할 수도 있으나 본 구성에서는 리어 브레이크로 한다.And between the master cylinder (3) and the brakes (5, 7) are provided with hydraulic lines (11, 13) enabling the hydraulic supply and discharge therebetween. The brakes 5 and 7 may also be front brake rear brakes to improve braking performance on an uphill road, but in this configuration, they are rear brakes.
상기 유압 라인(11,13)에는 마스터 실린더(3)에서 발생된 유압은 항상 브레이크(5,7)로 공급 가능케 하고, 브레이크(5,7)에서 배출되는 유압을 제어할 수 있는 제 1,2 솔레노이드 밸브(15,17)가 설치되어 있다.In the hydraulic lines 11 and 13, the first and second hydraulic pressures generated from the master cylinder 3 can be supplied to the brakes 5 and 7 at all times, and the hydraulic pressures discharged from the brakes 5 and 7 can be controlled. Solenoid valves 15 and 17 are provided.
상기 제 1,2 솔레노이드 밸브(15,17)는 전원과 연결되며, 이들 사이에는 전원을 단속하는 스위치(19)가 설치되어 있다. 이 스위치(19)는 운전자의 수조작으로 온/오프시킬 수 있음은 물론이고 가속 페달(미도시)의 작동으로 오프시킬 수 있도록 구성되고 설치된다.The first and second solenoid valves 15 and 17 are connected to a power source, and a switch 19 intermittent therebetween is provided therebetween. This switch 19 is configured and installed to be turned on / off by the driver's manual operation as well as to be turned off by operation of an accelerator pedal (not shown).
상술한 바와 같이 구성된 차량의 업힐 출발장치를 구비한 차량으로 오르막 길에서 브레이크 페달(1)을 작동시키면 도 1에 도시된 바와 같이, 마스터 실린더(3)에서 발생된 유압이 유압 라인(11,13)을 경유하여 브레이크(5,7)로 공급되어 이들을 작동시켜 차체를 정지시킨다.When the brake pedal 1 is operated on an uphill road with a vehicle having an uphill starting device of a vehicle configured as described above, as shown in FIG. 1, the hydraulic pressure generated in the master cylinder 3 is reduced by the hydraulic lines 11 and 13. Is supplied to the brakes 5 and 7 to operate them to stop the vehicle body.
그 후 재출발할 때에는 도 2에 도시된 바와 같이, 운전자가 먼저 스위치(19)를 온시킨다. 따라서 전원의 전류가 제 1,2 솔레노이드 밸브(15,17)로 공급되어 이들을 작동시켜 마스터 실린더(3)와 브레이크(5,7)를 연결하는 유압 라인(11,13)을 각각 차단시킨다. 이 상태에서는 브레이크 페달(1)을 해방시켜도 브레이크(5,7)를 작동시키던 유압은 마스터 실린더(3)로 배출되지 않고 계속해서 브레이크(5,7)를 작동시키게 된다.Then, when restarting, the driver first turns on the switch 19, as shown in FIG. Therefore, the current of the power supply is supplied to the first and second solenoid valves 15 and 17 to operate them to shut off the hydraulic lines 11 and 13 connecting the master cylinder 3 and the brakes 5 and 7, respectively. In this state, even when the brake pedal 1 is released, the hydraulic pressure which operated the brakes 5 and 7 is not discharged to the master cylinder 3 and continues to operate the brakes 5 and 7.
그리고 브레이크 페달(1)을 해방시키고, 변속단을 선택한 후 가속 페달을 작동시킨다. 따라서 스위치(19)가 해방되어 제 1,2 솔레노이드 밸브(15,17)의 작동을 해방시켜 브레이크(5,7)를 작동시키던 유압을 배출시켜 브레이크(5,7)를 해방시킴과 동시에 뒤로 밀림없이 차량을 출발시킨다.Then release the brake pedal (1), select the gear stage and operate the accelerator pedal. Therefore, the switch 19 is released to release the operation of the first and second solenoid valves 15 and 17 to discharge the hydraulic pressure that operated the brakes 5 and 7 to release the brakes 5 and 7 and to push backwards. Start the vehicle without
상술한 바와 같이 본 고안에 따른 차량의 업힐 출발장치는 운전자의 의도로 스위칭 수단을 작동시킴에 따라 밸브수단을 작동시켜 브레이크 페달의 해방과는 별도로 브레이크를 계속 작동시키고, 가속 페달을 작동시켜 스위칭 수단을 해제시킴에 따라 밸브수단을 작동시켜 브레이크를 해방시키므로 오르막길에서 정지 후, 재출발시 차체가 뒤로 밀리는 것을 방지할 수 있다.As described above, the uphill starting device for a vehicle according to the present invention operates the valve means according to the driver's intention to operate the switching means, and continuously operates the brake separately from the release of the brake pedal, and operates the acceleration pedal to switch the switching means. By releasing the brake, the valve means is actuated to release the brake, so that the vehicle body can be prevented from being pushed back when restarting after stopping at an uphill road.
