Abstract: A collision avoidance ECU sets a model deceleration change amount to smaller value in a state in which it is difficult to reduce the speed of a host vehicle than in a state in which it is easy to reduce the speed of the host vehicle. The collision avoidance ECU calculates a first target value by multiplying the model deceleration change amount by the elapsed time. The collision avoidance ECU obtains a subtraction value by subtracting the current reference relative deceleration from the first target value. Then, the collision avoidance ECU determines a target relative deceleration to be a greater value when the subtraction value is large than when the subtraction value is small, and carries out brake control so that the reference relative deceleration approaches the target relative deceleration.

Abstract translation: 防碰撞ECU在难以降低本车辆的速度的状态下比在容易降低主车辆的速度的状态下将模型减速度变化量设定为较小的值。 碰撞避免ECU通过将模型减速度变化量乘以经过时间来计算第一目标值。 碰撞避免ECU通过从第一目标值减去当前基准相对减速度来获得减法值。 然后，当减法值大于减法值小时，碰撞避免ECU将目标相对减速度确定为更大的值，并执行制动控制，使得基准相对减速度接近目标相对减速度。
