Early warning system and method for visual blind area of vehicle, and vehicle

Abstract

The invention relates to the technical field of early warning systems for vehicles, and discloses an early warning system and method for a visual blind area of a vehicle, and the vehicle. The early warning system for the visual blind area of the vehicle comprises a controller, and a radar assembly, an early warning assembly and an early warning decision module which are respectively connected with the controller, wherein the radar assembly is used for collecting motion information of obstacles in a preset range on the side of the vehicle; the early warning decision module is used for acquiring driving information of the vehicle in driving, acquiring a first motion track of vehicle driving according to the information in driving, acquiring a second motion track of an obstacle according to the motion information acquired by the radar assembly, acquiring an early warning condition according to the first motion track and the second motion track, and sending the early warning condition to the controller; and the controller is used for sending an alarm instruction of a corresponding grade to the early warning assembly according to the early warning condition, so the early warning assembly performs early warning of different strength grades, the intelligent degree of the early warning system is improved, the occurrence rate of accidents caused by the blind area of the vehicle is reduced, and the driving burden of a driver is relieved.

Description

technical field [0001] The invention relates to the technical field of vehicle early warning systems, in particular to a vehicle blind spot early warning system, method and vehicle. Background technique [0002] The main reason for road safety accidents of heavy trucks is that there is a blind spot in the side vision, and the driver fails to detect pedestrians and vehicles, causing accidents; the secondary reason is that there is a difference between the inner and outer wheels of heavy trucks, and the driver fails to accurately predict the trajectory of the truck. Accidents, or accidents caused by pedestrians and surrounding vehicles accidentally entering the track of the truck due to the lack of consideration of the difference between the inner and outer wheels of the truck. These traffic accidents involving heavy trucks are not uncommon, causing irreparable losses to the safety of people's lives and property. [0003] At present, in the prior art, drivers mainly rely on t...

[0002] The main reason for road safety accidents of heavy trucks is that there is a blind spot in the side vision, and the driver fails to detect pedestrians and vehicles, causing accidents; the secondary reason is that there is a difference between the inner and outer wheels of heavy trucks, and the driver fails to accurately predict the trajectory of the truck. Accidents, or accidents caused by pedestrians and surrounding vehicles accidentally entering the truck's driving track due to the lack of consideration of the difference between the inner and outer wheels of the truck

[0003] At present, in the prior art, drivers mainly rely on the traditional mirrors on both sides to observe, and the range of observation of this mirror is limited; some vehicles are adding additional warning devices, which will emit sounds and lights to remind pedestrians when turning Dodging, or warning the driver by detecting obstacles around the vehicle, or realizing panoramic observation through the camera; these methods have certain limitations: reminding pedestrians to avoid the situation that pedestrians do not avoid in time or even do not avoid, the actual effect Poor, it may even cause the resentment of surrounding pedestrians or vehicles; warn the driver, the distance of the obstacle cannot be obtained directly, and the driver can only make frequent observation and deceleration, but cannot respond reasonably according to the risk of collision; panorama Observation requires the driver to stare at the screen and observe all the time. At this time, the driver needs to take care of other situations at the same time, which is easy to be distracted
