Embodiment Construction

[0224]Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0225] Before introducing the specific content of the embodiments of the present disclosure, first introduce the actual application occasions involved in the present disclosure. Reverse overtaking warning (English: Do Not Pass Warning, abbreviation: DNPW) means that the vehicle is driving on the road, because the reverse Lane overtaking, a technology that warns the driver of the vehicle when there is a risk of collision with a vehicle traveling in the opposite direction on the opposite lane. The early warning will be applicable to the warning of the danger of overtaking and changing lanes on ordinary roads and highways in cities and suburbs. The method of rev...

Abstract

The invention relates o an overtaking early warning method and device. The method comprises steps that the state information of a present vehicle and vehicles around the present vehicle is acquired; according to the state information of the present vehicle and the vehicles around the present vehicle, orientation types of the vehicles around the present vehicle are determined; if a vehicle of the vehicles around the present vehicle is in a reverse direction in front, whether the present vehicle satisfies reverse overtaking conditions is determined according to the state information of the present vehicle, the vehicles in front and the front reverse vehicle; an overtaking early warning strategy corresponding to the determination result is outputted according to the determination result of whether the present vehicle satisfies the reverse overtaking conditions. The method is advantaged in that problems of lack of accuracy and safety caused by artificial determination during reverse overtaking in the prior art are solved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular to a method and device for early warning of overtaking. Background technique [0002] With the development of the economy, the number of cars continues to increase, the density of urban vehicles is high, the traffic conditions have become complicated, and traffic accidents caused by overtaking have also occurred frequently. Safe and effective overtaking has always been a hotspot in vehicle technology research, especially in the process of reverse overtaking. Due to the need to comprehensively judge multi-lane information, the driver needs to have good driving behavior and driving experience. If the driver lacks experience or makes a wrong judgment, it is extremely difficult It is easy to cause traffic accidents, so an effective reverse overtaking warning method to assist drivers to overtake safely is a necessary method to reduce traffic accidents. [0003] The overtaking ...
