    • A drive assist system includes an assist starting part starting assist, a detection part detecting relative distances and speeds between a vehicles, a calculation part calculating collision risks when changing a lane by the basis of the relative distances and speeds, a first judgment part judging whether the lane can be changed by the relative distances, speeds and the collision risks, a decision part deciding a target space for lane change by the relative distances and speeds when the lane cannot be changed, a second judgment part judging whether a lane changeable space is in the target space, a setting part setting a target speed for the vehicle go to a lane change waiting position when no space and to setting a target speed the vehicle enters a lane changeable position when there is the space, and a control part controlling a speed of the vehicle reaches the target speed.
    • 驱动辅助系统包括辅助起动部起动辅助,检测车辆之间的相对距离和速度的检测部,基于相对距离和速度来改变车道时的碰撞风险的计算部,第一判断部判断是否 可以通过相对距离,速度和碰撞风险来改变车道,决定部件通过车道不能改变时的相对距离和速度来确定车道变换的目标空间,第二判断部分判断车道可变空间是否为 在目标空间中,当没有空间时,设定车辆的目标速度的设定部分进入车道变更等待位置,并且当存在空间时设定车辆进入车道可变位置的目标速度,以及控制部 车速达到目标速度。
