본 고안은 밧데리와 연결된 구동모터를 통해 각 바퀴를 구동하는 전기자동차에 있어서 운행중인 차량을 정지시킬 때에 응용되는 전기자동차의 회생제동장치에 관한 것으로, 더 자세하게는 운전자의 스위치조작에 의하지 않고서도 악셀 페달에서 발을 떼는 것에 의해 자동으로 회생제동이 걸릴 수 있도록 개선한 것에 관한 것이다.The present invention relates to a regenerative braking apparatus for an electric vehicle that is applied when the vehicle is stopped in an electric vehicle that drives each wheel through a driving motor connected to a battery. More specifically, the accelerator motor is operated without the driver's switch operation. It is about improving regenerative braking by automatically releasing foot.
최근 들어 환경에 관한 관심이 높아지면서 배기가스가 얼어 환경에 무해한 전기자동차에 대한 연구개발 노력이 계속되고 있는 바, 이러한 연구노력의 결과로 이미 구동장치나 제동장치 등을 포함한 많은 부분에 상당한 진전이 있어 전기자동차가 점차 실용화되고 있는 실정이다.Recently, as interest in the environment has increased, research and development efforts on electric vehicles, which are harmless to the environment due to freezing of exhaust gases, have been continued. Therefore, electric vehicles are gradually being put into practical use.
본 고안은 전기자동차의 각 부분 중 각 바퀴를 구동하는 구동모터로부터의 회생에너지를 밧데리에 축적하면서 구동모터에 제동력을 가하는 회생제동장치에 관계하는 것이다. 종래에 있어서 상기 회생 제동장치는 국내 공개특허공보 제 95-13815호와 같이 밧데리가 회생 에너지를 회수할 수 없이 과 충전 상태이고, 평활 콘덴서의 단자전압으로부터 전압 레벨 판정기가 판정한 경우, 회생/환류모드 선택기는, 에너지를 소비하는 환류모드로 교체해서, 토오크전류 감소신호발생기에 의해서 여자전류성분만이 일차권선에 흐르는 구동모터에 구동토오크를 발생시키지 않고 제어가 실행되고, 구동모터 내부 등의 열손실이 있어 밧데리의 에너지가 소비되는 경우 과 충전 상태가 파괴되어 회수능력이 회복되면 회생/환류모드 선택기는, 회생제동력이 얻어지는 회생모드로 교체되도록 하는 것 등이 제안된 바 있다.The present invention relates to a regenerative braking device that applies braking force to a driving motor while accumulating regenerative energy from a driving motor for driving each wheel of each part of the electric vehicle. In the related art, the regenerative braking apparatus is in an overcharge state without a battery recovering regenerative energy as in Korean Patent Laid-Open Publication No. 95-13815, when regenerative / reflux is determined by the voltage level determiner from the terminal voltage of the smoothing capacitor. The mode selector is replaced with a reflux mode that consumes energy, and the torque current reduction signal generator performs control without generating a drive torque to the drive motor in which only the excitation current component flows in the primary winding, and generates heat inside the drive motor. It is suggested that the regenerative / reflux mode selector be replaced with the regenerative mode in which regenerative braking power is obtained when there is a loss and when the battery energy is consumed and the state of charge is destroyed and the recovery capacity is restored.
그러나 이와 같은 종래의 장치에 있어서는 회생제동이 모두 스위치조작에 의한 것이기 때문에 운전자의 조작상의 위험이 수반될 뿐 아니라 밧데리의 충전특성이나 구동모터의 효율성, 브레이크의 제동거리등이 고려되어 있지 않기 때문에 효율적인 회생제동을 할 수 없게 되는 문제가 있게 된다.However, in such a conventional device, the regenerative braking is all done by a switch operation, which not only entails a risk of driver's operation, but also does not consider the charging characteristics of the battery, the efficiency of the driving motor, the braking distance of the brake, etc. There is a problem that regenerative braking becomes impossible.
본 고안은 상기 종래의 실정을 감안하여 안출한 것이며, 그 목적은 전기자동차를 제동함에 있어서 유압제동과 회동제동을 동시에 활용하여 안전성과 에너지효율을 높일 수 있도록 하는 한편 구동모터의 효율성과 밧데리의 충전특성, 브레이크의 제동거리를 충분히 고려하여 효율적 제동이 될 수 있도록 하는 전기자동차의 회생제동장치를 제공하는 데에 있는 것이다.The present invention has been devised in view of the above-mentioned conventional situation, and its purpose is to improve safety and energy efficiency by simultaneously utilizing hydraulic braking and rotation braking in braking electric vehicles, while driving the efficiency of the driving motor and charging the battery. The present invention is to provide a regenerative braking apparatus for an electric vehicle that allows efficient braking in consideration of characteristics and braking distance of a brake.
이하 상기의 목적을 달성하기 위한 본 고안의 구체적인 내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.Hereinafter, the specific content of the present invention for achieving the above object will be described in more detail based on the accompanying drawings.
즉, 본 고안은 제1도와 같이 퍼텐시오메터박스(potentiometer)(2)에 설치한 리미트스위치(limit switch)(3)를 플렉시블와이어(flexible wire)(4)를 통해 악셀페달(accel pedal)(1)에 연결하고, 리미트스위치(3)를 변환장치(inverter)(5)에 접속함으로써 악셀 페달(1)에서 발을 떼면 자동적으로 회생제동이 걸릴 수 있도록 하여서 되는 것이다.In other words, the present invention is a limit switch (3) installed in the potentiometer (2) as shown in FIG. 1 through a flexible wire (4) an accelerator pedal (accel pedal) ( 1) and the limit switch 3 to the inverter 5 so that the regenerative braking is automatically applied when the foot is released from the axel pedal 1.
한편 본 고안에서는 제2도와 같이 악셀 페달(1)에서 발을 떼면 리미트스위치(3)가 온되도록 회로가 구성되며, 제3도와 같이 저속에서는 회생제동에너지가 상당히 작기 때문에 제동거리를 줄이고, 고속에서는 에너지가 크기 때문에 제동거리를 길게함과 동시에 밧데리(미도시)의 충전효율을 감안하여 회생제동량이 결정되도록 한다.On the other hand, in the present invention, the circuit is configured so that the limit switch 3 is turned on when the foot is released from the axel pedal 1 as shown in FIG. 2, and the braking distance is reduced because the regenerative braking energy is very small at the low speed as shown in FIG. Since the energy is large, the braking distance is extended and the regenerative braking amount is determined in consideration of the charging efficiency of the battery (not shown).
즉, 저속일 때는 회생제동량을 많게 하고, 제동거리를 짧게 하며, 고속일 경우에는 회생제동량을 적게하고, 제동거리를 길게한다.That is, at low speed, the regenerative braking amount is increased, the braking distance is shortened, and at high speed, the regenerative braking amount is reduced and the braking distance is increased.
이상에서와 같은 본 고안에 있어서는 악셀페달(1)로부터 발을 떼게 되면 리미트스위치(3)가 온되어 자동적으로 회생제동이 걸릴 수 있게 되고. 차량속도를 감안하여 회생제동량이 조절되므로 전기자등차의 제동성능을 크게 향상시킬 수 있게 되는 데다가 운전자에게는 최적의 승차감을 제공할 수 있게 되는 등의 효과를 얻을 수 있게 된다.In the present invention as described above, when the foot is released from the axel pedal 1, the limit switch 3 is turned on so that regenerative braking can be automatically applied. Since the regenerative braking amount is adjusted in consideration of the vehicle speed, the braking performance of the armature vehicle can be greatly improved, and the driver can provide the optimum riding comfort.
