Background technique
Highway with it is quick, safe, comfortable the features such as and advantage play an important role in Modern Traffic transportation system,
Promote each intercity connection by highway, expanding economy along drive effectively plays its social benefit.But with family
The increase of car quantity, road traffic condition and day it is all under so that congested in traffic phenomenon happens occasionally.And in such case
Under, the hypervelocity behavior of driver easily causes traffic accident, therefore need to be monitored to the driving behavior of driver, Du
Hypervelocity behavior absolutely, thus the driving safety of support vehicles.
In the prior art, speed limiting system is set on vehicle, is controlled by travel speed of the speed limiting system to vehicle,
There is following two disadvantage in this manner: first is that the speed that speed limiting system is limited is identical, in the situation that people is few, vehicle is few
Under, travel speed cannot be promoted, so that driver needs to take more time in road；Second is that the speed limit of current road segment is believed
Breath, if be adjusted speed limiting system according to speed-limiting messages, needs uninterruptedly to obtain, to data transmission bauds and signal strength
It there are certain requirements, if be not adjusted according to speed-limiting messages to speed limiting system, that is easy to appear hypervelocity row in the process of moving
For the situation not up to standard with speed, to influence traffic order.
Therefore a kind of limiting vehicle speed that can the traveling of driver be prejudged and effectively be controlled its travel speed is needed
System.
Summary of the invention
It, being capable of going through according to driver the invention is intended to provide a kind of limiting vehicle speed system and method for remotely controlling
History hypervelocity record judges whether driver is easy to appear hypervelocity behavior under present case, and when being easy to appear hypervelocity behavior, root
It requires to control the travel speed of vehicle according to the speed limit of current road segment.
