Abstract
【解決手段】車両1の挙動制御に用いる目標横加速度Gytを車両1の走行時における横加速度実測値Gysと横加速度推定値Gyeとに基づいて推定する車両状態量推定装置2において、横加速度実測値Gysと横加速度推定値Gyeとに基づいて目標横加速度Gytを推定する場合には、車両1の横滑りの状態に応じて横加速度実測値Gysと横加速度推定値Gyeとに重み付けを行うことにより推定すると共に、横滑りが所定値以上になった場合には横滑りの状態に関わらず横加速度実測値Gysの重み付けが大きい状態を維持し、横加速度実測値Gysと横加速度推定値Gyeとの差が所定値以下の状態が所定時間継続した場合に、横加速度実測値Gysの重み付けが大きい状態を解除する。

Description
図1は、実施形態に係る車両状態量推定装置を備える車両の概略図である。実施形態に係る車両状態量推定装置2を備える車両1は、内燃機関であるエンジン12が動力源として搭載され、エンジン12の動力によって走行可能になっている。このエンジン12には変速装置の一例である自動変速機15が接続されており、エンジン12が発生した動力は、自動変速機15に伝達可能になっている。この自動変速機15は、変速比が異なるギア段を複数有しており、自動変速機15で変速した動力は動力伝達経路を介して、車両1が有する車輪5のうち駆動輪として設けられる左右の前輪6へ駆動力として伝達されることにより、車両1は走行可能になっている。これらのように、エンジン12や自動変速機15等、駆動輪である前輪6に駆動力を伝達可能な装置は、駆動装置10として設けられている。また、駆動装置10を構成する自動変速機15には、当該自動変速機15の出力軸(図示省略)の回転速度を検出することを介して車速を検出可能な車速検出手段である車速センサ16が設けられている。
