Embodiment 1

[0056] The embodiment of the present invention provides a kind of expressway speed limit method, refer to figure 1 , the method includes:

[0057] Step S11, obtaining the normal driving maximum speed of each road section in the expressway.

[0058] Step S12, acquiring the current position and current speed of the vehicle on the expressway in real time.

[0059] Step S13, determine the current road segment of the vehicle according to the current position of the vehicle, and then determine the maximum normal driving speed of the vehicle on the current road segment.

[0060]In step S13, determine which road section (current road section) the vehicle is currently located in the expressway according to the current position of the vehicle. The maximum normal driving speed corresponding to the road section (the maximum normal driving speed of the current road section).

[0061] Step S14, when the current speed of the vehicle is greater than the maximum normal driving speed of the ...

Embodiment 2

[0070] The embodiment of the present invention provides a kind of expressway speed limit method, refer to figure 2 , the method includes:

[0071] Step S21, obtaining the maximum speed of normal driving and the maximum speed of overtaking for each section of the expressway.

[0072] Specifically, the central platform sets the maximum speed for normal driving and the maximum speed for overtaking respectively for each road section. Here, the maximum speed for normal driving refers to the maximum speed when the vehicle is running normally on the corresponding road section; The maximum speed when overtaking, in step S21, the normal driving maximum speed and the overtaking maximum speed of each road section in the expressway pass through GPRS (General Packet Radio Service, general packet radio service) or 3G (3rd-generation, third generation) from the central platform. mobile communication technology) network access.

[0073] Step S22, acquiring the current position and current ...

Embodiment 3

[0087] The embodiment of the present invention provides a kind of expressway speed limit method, refer to image 3 , the method includes:

[0088] Step S31, obtaining the maximum normal driving speed, the maximum overtaking speed and the maximum overtaking time of each section of the expressway.

[0089] Step S32, acquiring the current position and current speed of the vehicle on the expressway in real time.

[0090] Step S33, determine the current road segment of the vehicle according to the current position of the vehicle, and then determine the maximum normal driving speed of the vehicle on the current road segment.

[0091] Step S34, when the current speed of the vehicle is greater than the maximum normal driving speed of the current road segment, the vehicle is controlled to travel at a speed lower than the maximum normal driving speed of the current road segment.

[0092] Step S35, after receiving the ready-to-overtake signal sent by the vehicle, record the time when t...

Abstract

The invention discloses a highway ratespeed-limiting method and system and relates to the field of car networking. The method comprises the following steps: acquiring the highest rate speed of each road segment in a highway during normal running; real-timely acquiring the current positions and rates speeds of cars on the highway; determining the current road segments of the cars according to the current positions of the cars so as to further determine the highest rate speed of the current road segment of the cars during normal running; when the current rates speeds of the cars are higher than the highest rate speed of the current road segments during normal running, controlling the cars to run at the rate smaller than the highest rates speeds of the current road segment during normal running. By adopting the method, the normal running rates speeds of cars are actively limited, so that the overspeed problem of the highway is radically solved and traffic accidents caused by overspeed can be avoided to some extent.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to an expressway speed limiting system and a method thereof. Background technique [0002] In recent years, with the continuous development of the economy and society, the construction of expressways has entered a period of rapid development. However, as expressways have exerted huge social and economic benefits and shortened the time-space distance between cities, traffic safety issues have attracted widespread attention. Especially the traffic accidents caused by speeding pose a great threat to the safety of people's lives and properties. The tragedy of the scene, the serious consequences, and the far-reaching impact are unmatched by general road traffic accidents. [0003] In order to restrain the driver's speeding behavior, the existing method is to install vehicle speed detectors and camera equipment on the expressway. When the vehicle speed detector detects that a passing v...
