The invention discloses a method for preventing accidental overspeed. Overspeed is prevented through a navigation system, a GPS positioning system, a vehicle speed detection system, a vehicle controlsystem and a brake system which are arranged on a vehicle. The method for preventing accidental overspeed comprises the following steps of 1, navigation setting and road condition acquisition; 2, performing real-time navigation positioning and vehicle speed detection; step 3, current and promising speed limit prompts; and 4, performing automatic braking and speed limiting in advance, the whole vehicle control system triggering the brake system to act to conduct braking and speed reducing before entering the speed limiting road section, and the speed being reduced to be lower than the speed limiting speed per hour before entering the speed limiting road section. Whether a front road section is a speed limiting belt or not in different form states in the driving process is obtained in advance, the corresponding speed limiting information is obtained to judge whether overspeed exists or not, and a driver is reminded to conduct standard driving operation in advance, and meanwhile, the brake system is automatically started to decelerate before entering the speed limit belt, so driving safety is ensured.

    一种预防意外超速的方法,通过整车上设置有的导航系统、GPS定位系统、车速检测系统、整车控制系统、刹车系统以预防超速;所述的预防意外超速的方法包括以下步骤:步骤1,导航设定与路况获取;步骤2,实时导航定位与车速检测;步骤3,当前与前途限速提示;步骤4,提前自动刹车限速,整车控制系统于限速路段前触发刹车系统动作进行刹车减速,在进入限速路段前将速度降至限速时速以下。本发明对驾驶过程中不同的形式状态下前方路段是否为限速带进行提前获取,并获取对应的限速信息以判断是否超速,提前提示驾驶人员进行规范驾驶操作;同时对于进入限速带前未及时降速进行自动启动刹车系统降速,保证行驶安全。
