| Abstract(J) | 車両の動制御を行うのに最も重要な変数であるエンジントルクの制御を,エアフロメータを備えた電制スロットルと電制トランスミッションを組み合せたシステムで可能にした.同時に,加減速時の空燃比とトルクのばらつきを抑制し,アクセル位置と道路の表面状況から求められる目標トルクにスロットルを合わせる制御アルゴリズムを開発した. Translation |
| Abstract(E) | Air - fuel ratio characteristics which exert a large influence on exhaust emissions and driveabiity were investigated for an engine drivetrain control system. In the system, the driving torque, one of the main variables for vehicle dynamic control with spark ignition engines can be controlled by using an electronically controlled throttle valve with air flow meters and an electronically controlled transmission. The control algorithms of the throttle valve against the target torque which is given by accelerator position and road surface conditions were clarified so as to reduce the fluctuations in the output torque and the air - fuel ratio during acceleration and braking on both high and low traction roads. |
