Method and system for outputting driving prompt information and vehicle

Abstract

The invention provides a method and system for outputting driving prompt information and a vehicle, and the method comprises the steps: obtaining traffic light data on a driving route of the vehicle, including the red light time period and the green light time period of each traffic light on the driving route of the vehicle, and the distance between each traffic light and the vehicle; acquiring driving data of a front vehicle, wherein the driving data comprises the speed of the front vehicle and the relative distance between the front vehicle and the vehicle; according to the traffic light data and the driving data of the front vehicle, obtaining a predicted driving time-driving distance curve range of the vehicle; and outputting driving distance range prompt information according to the predicted driving time-driving distance curve range of the vehicle. According to the method provided by the invention, the vehicle can pass in the time period when each traffic light on the driving route is green, the vehicle does not need to be stopped and started frequently, and the vehicle wear and the fuel consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a method, a system and a vehicle for outputting driving prompt information. Background technique [0002] With the rapid development of automobile intelligence in today's era, the road and traffic conditions ahead can be estimated through advanced information interaction and communication technology, which makes the use of vehicles and the energy utilization of vehicle power systems more effective. Specifically, it can include the collection of road data ahead through navigation systems, radars and cameras, so as to predict the road and traffic conditions ahead. With the continuous development, future V2X (vehicle-to-X: vehicle and external information interaction), V2V (Vehicle-to-Vehicle: Vehicle-to-Vehicle Information Interaction), V2I (Vehicle-to-Infrastructure: Vehicle-to-Infrastructure Information Interaction) and other technologies make the prediction of road a...

AI Technical Summary

Problems solved by technology

[0003] At present, it is to predict the road and traffic conditions ahead, plan a better driving route for the user, and control the deceleration of the vehicle to stop the vehicle based on the red light situation detected by the camera. It is impossible to avoid the vehicle reaching the traffic light and encountering a red light. When the vehicle needs to stop and start frequently, it will cause wear and tear on the vehicle and fuel consumption
