Embodiment Construction

[0029] figure 1 It is an application scenario diagram shown in an exemplary embodiment of the present invention.

[0030] Such as figure 1 As shown, when vehicles are driving on the road, they often pass through intersections with traffic lights. Vehicles need to wait for the signal light corresponding to their lane to turn green at the intersection before passing. If it happens to be a red or yellow light when the vehicle passes the intersection, it is necessary to control the vehicle to stop and wait, and restart the vehicle after the signal light turns green.

[0031] Since it takes a certain amount of time for the vehicle to restart the serial number from being completely stationary, this leads to the problem of low efficiency of vehicle crossings in the prior art.

[0032] In the method provided in this embodiment, the vehicle guidance speed can be determined according to the vehicle, the traffic conditions around the vehicle, and the signal lights at the intersection,...

Abstract

The invention provides a vehicle speed guiding method and device and a vehicle, and the method comprises the steps: obtaining the position information of the vehicle, and determining the distance from the vehicle to a next signal lamp intersection according to the position information; if the distance meets the preset requirement, collecting driving information of other vehicles with the distance smaller than the preset distance from the vehicle and signal lamp information of a signal lamp intersection; and determining the guiding speed of the vehicle according to the driving information and the signal lamp information of other vehicles. According to the method provided by the embodiment of the invention, the guiding speed is determined according to the distance from the vehicle to the intersection and the road condition around the vehicle, so that the vehicle can safely and efficiently pass through the intersection, and the traffic efficiency of the intersection can be improved.

Description

technical field [0001] The present disclosure relates to vehicle-road coordination technology, and in particular to a vehicle speed guidance method, device and vehicle. Background technique [0002] At present, cars are an indispensable means of travel for people. People can drive cars to where they want to go. [0003] Wherein, when the vehicle runs on the road, it often encounters an intersection with traffic lights. In order to wait for the red light, you need to brake and start the car again when the light turns green. [0004] It takes a certain amount of time and energy to start the vehicle after it is completely stationary, which will lead to low crossing efficiency and waste of energy. Therefore, there is an urgent need for a method that can improve the efficiency of vehicles passing through intersections. Contents of the invention [0005] The present disclosure provides a vehicle speed guidance method, device and vehicle to solve the problem of low efficiency...
