The invention provides a curve vehicle speed prompting method and a curve vehicle speed prompting device. The curve vehicle speed prompting method comprises the steps of obtaining information of a to-be-entered curve; obtaining driving influence information; obtaining ideal curve speed information according to the to-be-entered curve information and the driving influence information; obtaining distance information from the current vehicle to the entrance of the to-be-entered curve; acquiring current vehicle speed information; and according to the current vehicle speed information, the information of the distance between the current vehicle and the entrance of the to-be-entered curve and the ideal curve vehicle speed information, whether deceleration prompt information is generated or not is judged, and if yes, the deceleration prompt information is generated. According to the scheme, the ideal curve speed information when the vehicle arrives at the front to-be-entered curve is obtained, and the vehicle is reminded to pay attention to speed reduction; the method comprises the following steps: performing segmentation processing on a continuous turning road section of a to-be-entered curve in front of a vehicle to obtain ideal curve speed information about the vehicle arriving at each turning road section of the to-be-entered curve in front of the vehicle; and adjusting the distance to the front to-be-entered curve to remind the vehicle to decelerate in advance.

    本申请提供了一种弯道车速提示方法及弯道车速提示装置,包括:获取待进入弯道信息;获取行车影响信息;根据待进入弯道信息以及行车影响信息获取理想弯道车速信息;获取当前车辆距离待进入弯道的入口处的距离信息;获取当前车速信息;根据当前车速信息、当前车辆距离待进入弯道的入口处的距离信息以及所述理想弯道车速信息判断是否生成减速提示信息,若是,则生成减速提示信息。通过上述方案,获得关于在车辆到达前方待进入弯道时理想弯道车速信息,提醒车辆注意减速;通过对车辆前方待进入弯道的连续转弯路段做分割处理,获得关于在车辆到达前方待进入弯道各个转弯路段的理想弯道车速信息;调整与前方待进入弯道的距离,提前提醒车辆减速。
