電気自動車のタイヤ稼働率を用いた車両運動制御の研究（第2報，インホイールモータ用稼働率制御の車両運動性能試験的検討）

摘要

近年自動車の化石燃料消費による地球環境悪化へのrn対策のひとつとして，電気自動車が見直され普及しつrnつある．その中でも四輪独立駆動電気自動車は，各駆rn動輪への駆動力配分が自由にかつ直接的に行え，駆動rn源がモータであるのでトルク応答が高速であり，そのrnトルクを正確に把握できるというメリットがある．%It has been shown in our first report that DYC is not compatible with the tire force usage equalization and it is important to consider total tire force F_x and F_y as feedback signals for DYC being compatible with the tire force usage equalization. Also, the control logic devised then has been found very effective in simulation. In this report, an attempt has been made to clarify whether the control logic as predicted by simulation is effective or not for real vehicle by conducting real electric vehicle run tests. It has been found that the control logic of this study is very effective for the independent wheel in motor electric vehicle. Also, handling has become neutral steering by using our control logic, and consequently, the vehicle could be neutrally steer up to higher speed than without control.
