AI Technical Summary

Problems solved by technology

In the autonomous positioning mode of the satellite navigation receiver, there are several main errors of satellite orbit error, ionospheric error, tropospheric error and receiver noise, resulting in positioning accuracy generally above 10 meters, which cannot meet the application of lane level. Users cannot accurately know which lane they are in, so they cannot solve the application of lane-level accident alarms, lane change speeding reminders, and lane congestion reminders

Embodiment Construction

[0012] The solution of the present invention will be described in detail below in combination with the preferred embodiments thereof.

[0013] Such as figure 1 As shown, the method in this embodiment includes steps:

[0014] S101: Obtain vehicle diversion request information.

[0015] The vehicle driver controls the vehicle to divert according to the actual situation; the diversion information is sent to the server, and the server obtains the vehicle diversion request information. As another implementation, the positioning system may also be used here to monitor the position change of the vehicle entering the second lane from the first lane to determine whether the vehicle is diverted, and then obtain the vehicle diversion request information. Since the direct distance between the first lane and the second lane is relatively small, the positioning system here adopts a high-precision positioning system.

[0016] S102: Obtain current lane information, driving speed, lane info...

Abstract

The invention provides a vehicle control prompting method based on high-precision positioning. The vehicle control prompting method includes the steps of acquiring vehicle diversion request information and acquiring current lane information, running speed and position information after diversion of a vehicle as well as speed limiting information of a lane by means of differential positioning; judging whether the running speed is within the speed limiting information of the lane or not, and warning if not. The vehicle control prompting method is simple to operate and capable of solving the problem that running of rear vehicles is affected by overspeed or too low speed caused by the fact that the vehicle does not know the speed limiting information of the lane when in running diversion on a highway. Meanwhile, the invention further provides a vehicle control prompting system based on high-precision positioning.

Description

technical field [0001] The invention relates to the field of urban transportation, in particular to a high-precision positioning-based automobile control prompting method and system. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the problem of urban traffic congestion is becoming more and more serious, and the frequency of traffic accidents is increasing, which seriously affects people's normal life and work, so that life safety, intelligent transportation The system is internationally recognized as the best way to solve the problem of traffic congestion. The vehicle navigation system is an important part of the intelligent transportation system, and a key technology to achieve the lane-level navigation system is satellite navigation technology. [0003] GNSS (Global Navigation Satellite System) is a general term for all navigation satellite systems worldwide, including GPS (Global Positio...
