Description
実施形態の説明に先立ち、本発明の理解が容易になるよう、以下、図1〜図5を用いて、横運動に連係した前後運動制御について概要を述べ、アクチュエータによる応答性の違いに関する影響について述べる。
「横運動に連係した前後運動制御」
(1)G-Vectoring
ハンドル操作による横運動に連係して自動的に加減速することにより、前輪と後輪の間に荷重移動を発生させて車両の操縦性と安定性の向上を図る方法である。具体的な加減速指令値(目標前後加速度Gxc)は、以下数1に示す通り、
2: 加速度センサ
3: ジャイロセンサ
4: ステアリングホイール
5: 操舵角センサ
6: 障害物検出センサ
7: タイヤ
8: 車輪速センサ
9: 自車両位置検出センサ
10: ブレーキ制御ユニット
11: ブレーキアクチュエータ
12: 駆動トルク制御ユニット
13: 駆動アクチュエータ
14: 通信バスライン
15: 舵角制御ユニット
16: 舵角制御アクチュエータ
17: ブレーキペダルセンサ
18: アクセルペダルセンサ
19: 車両
