DBW自動車における車軸出力トルクと外乱負荷トルクの推定

概要

論文の詳細を見る
Recently, the vehicle which is adopting an electronically controlled throttle valve (ECTV) is controlled by DBW (Drive by wire) for the purpose of improving the automobiles performance. One of them is an optionally tuning for the accelerator pedal sensitivity, and it needs axle output torque as the feedback signal. Because the cost of hardware torque meter is the practical problem, the axle output torque should be estimated by adaptive observer with table-looking method. If the disturbance load torque by a slope of road and so on is not already known, observer can not be used. Therefore the disturbance load torque should be estimated without sensor also. Expected observation and control results are obtained by using the simulation which is identified with an experimental device.
