    • In a vehicle speed control system, each node existing ahead of a vehicle is detected, and a stable running speed at which the vehicle runs stably when the vehicle passes over each node, and a deceleration needed to accelerate/decelerate the vehicle so that the vehicle speed becomes the stable running speed at each node by the time when the vehicle arrives at the node are successively calculated. On the basis of the deceleration at each node, a point at which the maximum deceleration value is achieved is selected, and the vehicle is subjected to deceleration control so that the vehicle speed becomes the stable running speed at the point. When a point at which the curve degree is maximum is different from a point at which the deceleration value is maximum and also the point is located ahead of the vehicle, further necessary deceleration control is carried out.
    • 在车辆速度控制系统中,检测到存在于车辆前方的各节点,以及当车辆经过各节点时车辆稳定行驶的稳定行驶速度,以及加速/减速车辆所需的减速度,使得车辆 当车辆到达节点时,速度成为每个节点的稳定运行速度。 根据各节点的减速度,选择实现最大减速度值的点,对车辆进行减速控制,使得车速成为该点处的稳定运行速度。 当曲线度最大的点不同于减速度值最大的点,并且该点位于车辆前方时,进行进一步必要的减速控制。
