GT-DRIVE : 용도가 넓은 차량 및 drivetrain 동역학 해석 도구
• 엔진-변속기-차량 크기 정하기 및 matching
• 운전 사이클 시뮬레이션, 사이클 fuel economy 및 emission
• 차량 성능 예측
• driveline 부품 (예: 클러치, 토르크 컨버터, 변속기, 브레이크, 타이어 및 driveline 형상)의 모델링
• 엔진 및 powertrain 제어

GT-DRIVE는 static, dynamic(운전자 입력) 및kinematic(알려진 차량 상태) mode로 실행될 수 있으며, 또한
진보된 운전자 모델을 가지고있습니다. 엔진 모델의 세가지 level이 제공되며, 상세한 GT-POWER 모델과의 연결(GT-POWER V)을 포함합니다.

Static Mode:
• Vehicle-engine-transmission sizing/matching
• Gear-by-gear static charts of:
    - Tractive force
    - Tractive power
    - Acceleration at zero grade
    - Maximum grade at constant speed
    - Fuel consumption

Dynamic Mode:
• Control of accelerator, clutch, gear-shift and brake, using driver model, Simulink and/or built-in
  control library
• Auto-shifting (function of engine or vehicle speed and load)
• Acceleration times (e.g. 0-100 km/h and 0-400 m)
• Fuel consumption and emissions output
• Detailed component issues: torsional vibrations, clutch engagement, tire traction, etc.

Kinematic Mode:
• Input: vehicle speed schedule / driving cycle
• Calculates engine speed and torque required to follow the prescribed drive cycle
• Integrates fuel consumption and emissions, reports totals, averages, brake-specific and
  distance-specific results

Engine Models:
Level I (GT-Drive) with brake quantities from maps
• Scattered maps of BMEP, fuel efficiency and emissions
• Fast execution for long drive cycles

Level II Mean-value model, with maps
• Contains full intake and exhaust piping
• Warm-up of manifolds and turbocharger lag
• Medium execution speed for control applications
Level III (GT-PowerV) with full GT-Power cylinder model
• Otherwise same as Level II
• High fidelity engine model for detailed analysis

Driveline/Vehicle Models:
• Slipping elements: clutch, torque converter, tires, brake
• Road, vehicle trailer
• Control-based driver model
• Hybrid-electric vehicle components
• Two levels of driveline modeling:
    -  Pre-programmed, single degree-of-freedom, kine-matically
        connected "typical" driveline
    - Driveline model built from library elements (transmission,
       driveshaft, axle, vehicle body);
      allows modeling of different driveline configurations, compliant
      drivelines, torsional vibrations
      and gear lash


Expert System/Report Mode:
• User "asks" a set of queries such as:
    - Maximum grade possible in a gear
    - Fuel consumption and emissions for a given driving cycle
    - Acceleration from a standing stop to a given speed or distance
• Simulation automatically determines the number & types of simulations to run
• Automatically sets-up/submits simulations to answer all queries
• Creates a tabulated and indexed HTML summary report
• Users' standard set of queries can be saved for re-use
