    • 【課題】フロントタイヤがリアタイヤよりも早く摩耗することに起因する車両安定制御の不必要な早期作動を抑制すること。【解決手段】車両安定制御装置は、目標ヨーレートと実ヨーレートに基づいてアンダーステア度を算出し、アンダーステア度が作動閾値を超えた場合に、車両安定制御を作動させる。目標ヨーレートの算出式は、車両のスタビリティファクタをパラメータとして含み、目標ヨーレートは、スタビリティファクタが大きくなるほど低くなる。車両安定制御装置は、フロントタイヤの摩耗度、あるいは、フロントタイヤとリアタイヤとの間の摩耗度の差である摩耗度パラメータを算出する。摩耗度パラメータが摩耗閾値を超えた場合、車両安定制御装置は、スタビリティファクタを初期設定値よりも大きい値に補正する。【選択図】図6

    • PROBLEM TO BE SOLVED: To provide a behavior control device for a vehicle capable of performing an appropriate zero point correction in the behavior control device for the vehicle enabling the zero point correction of yaw rate sensors during travel and stop respectively. SOLUTION: When a yaw rate correction value (YR0) calculating condition during travel is effected during travel of a vehicle, a yaw rate correction value YR0M during travel is determined (steps S11, 12), and when the yaw rate correction value (YR0) calculating condition during stop is effected during stop, the yaw rate correction value YR0S during stop is determined (steps S15, 17). When the counter value CT indicating the elapsed time from the nearest YR0M correction point exceeds a predetermined threshold Thx, YR0M is replaced (steps S18, 19) by YR0S. When the absolute value Ydiff of the difference between YR0M and YR0S exceeds the threshold A, a control threshold of the vehicle behavior control (step S26) is augmented (steps S23, 24).

    • PROBLEM TO BE SOLVED: To provide a braking control device capable of surely responding to a driver's will to turn quickly, while securing the traveling stability of a vehicle on braking the vehicle for turning.
      SOLUTION: A target braking pressure Pti of each wheel is calculated based on the braking amount of the driver (S20). When the driver has no will to turn quickly (S30), the product Gy×V of a vehicle lateral acceleration Gy and a vehicle speed V is calculated, and the pressure increased amount A' of the front wheels is calculated so as to become as large as the absolute value of the product Gy×V (S80 to 110), or the pressure increased amount A' of the front wheels is calculated so as to become as large as the absolute value of the product Gy×V while a target braking pressure of the turning inside rear wheel is set to 0 (S70). Consequently, a braking force is controlled so that the larger the product Gy×V is, the higher the distribution ratio of the braking force of the front wheels against the rear wheels may be. On the other hand, when the driver has a will to turn quickly, the control over the distribution ratio of the braking force is not executed (S30, 120, 130).

    • PROBLEM TO BE SOLVED: To provide a behavior control system that suppresses a spinning behavior of a vehicle using a spinning state quantity, which is calculated based on a vehicle body slip angle, a derivative of the slip angle, and a second-order derivative thereof, as a control quantity, and avoid degradation of an effect of spin suppressing due to contribution of the second-order derivative of the vehicle body slip angle when a steering angle is retained after abrupt steering is performed once.SOLUTION: A system of the present invention is characterized in that after a second-order derivative of a vehicle body slip angle exceeds a predetermined value because a vehicle is steered in one of left-hand and right-hand directions, if an averaged value of steering angular velocities falls below a predetermined value, contribution of the second-order derivative of the vehicle body slip angle to a spinning state quantity is reduced.
