摘要： After a vehicle has entered a curve, a deviation (Sch) between a target turning state quantity Td and an actual turning state quantity Ta is computed. In a stage in which Sch does not reach a predetermined value after the vehicle has entered the curve, the possibility of the vehicle traveling in the curve is judged to be low, and the reliability of the curve information Rc, Pc is judged to be low. In this case, a determination for prohibiting execution of control (So=0) is made. In a stage after Sch has reached the predetermined value, the possibility of the vehicle traveling in the curve is judged to be high, and the reliability of the curve information Rc, Pc is judged to be high. In this case, a determination for permitting execution of the control (So=1) is made. Deceleration control is started and executed only when a control start condition is satisfied, and the determination for permission is made. Accordingly, even when the control start condition is satisfied, the deceleration control is not started, if the prohibition determination is made. Thus, the reliability of the curve information based on map information on the vehicle is evaluated reliably, and the deceleration control within the curve can be prevented from being unnecessarily executed on the basis of curve information whose reliability is low.

摘要翻译： 在车辆进入曲线之后，计算目标转弯状态量Td与实际转弯状态量Ta之间的偏差（Sch）。 在车辆进入曲线之后，在Sch达不到预定值的阶段，车辆在曲线中行驶的可能性被判断为低，并且曲线信息Rc，Pc的可靠性被判断为低 。 在这种情况下，进行禁止执行控制（So = 0）的判定。 在Sch达到预定值之后的阶段，车辆在曲线中行驶的可能性被判断为高，曲线信息Rc，Pc的可靠性被判定为高。 在这种情况下，进行允许执行控制的判定（So = 1）。 只有满足控制开始条件才开始执行减速控制，进行许可判定。 因此，即使满足控制开始条件，如果进行禁止判定，则不开始减速控制。 因此，可靠地评估基于车辆上的地图信息的曲线信息的可靠性，并且可以基于可靠性低的曲线信息来防止曲线内的减速控制被不必要地执行。
