Title FRONT WHEEL STEERING CONTROL DEVICE
Abstract A front wheel steering control device that is based on a theory of driving stability fora vehicle and improves driving stability of a vehicle relative to a steering angle.A front wheel steering control device for improving driving stability of a vehicle(100) has reading means for reading a steering angle and a vehicle speed of thevehicle, first calculation means for calculating, based on the steering angleand the vehicle speed read by the reading means, a yaw rate of the vehicle with aside-skid angle of the vehicles center of gravity always set at 0, secondcalculation means for calculating a target actual steering angle of front wheelsfor realizing the yaw rate calculated by the first calculation means, and controlmeans for controlling the steering of the vehicle based on the target actual steeringangle of front wheels calculated by the second calculation means. The steeringgear ratio and derivative steering gain of an ideal vehicle can be set relativelysimply and theoretically clearly.
Scope of claims (In Japanese)
【請求項1】車両の操縦安定性を向上させる前輪操舵制御装置において、前記車両のハンドル角と車速とを読み込む読込手段と、前記読込手段で読み込んだハンドル角と車速に基づいて、車体重心点横すべり角を常に0とする車両のヨーレイトを算出する第1の算出手段と、前記第1の算出手段で算出したヨーレイトを実現するための、目標前輪実舵角を算出する第2の算出手段と、前記第2の算出手段で算出した前記目標前輪実舵角に基づき、前記車両の操舵制御を行う制御手段とを有することを特徴とする前輪操舵制御装置。

【請求項2】前記目標前輪実舵角は、車両のハンドル角に比例したフィードフォワード実舵角と、該ハンドル角の微分値に一次遅れ要素を付加したフィードフォワード実舵角を重ね合わせて算出することを特徴とする請求項1に記載の前輪操舵制御装置。
