Problems solved by technology

For example, when a pedestrian is walking on the road, suddenly a silent vehicle passes by, it will be surprising; especially for the hearing-impaired, this situation is very dangerous, if the pedestrian does not realize that there is a car When passing by, turning suddenly in the direction of passing vehicles may cause a serious traffic accident that may cause personal injury or death
[0004] In order to solve the safety problem of electric vehicles on roadside pedestrians when driving at low speed, it is necessary to artificially add warning sounds. If the artificial warning sounds are not smart, it will cause noise problems

Embodiment Construction

[0038] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0039] figure 1 A flowchart showing a warning method based on an electric vehicle according to an embodiment of the present invention, the electric vehicle includes a pure electric vehicle and a hybrid vehicle capable of electric driving, such as figure 1 As shown, the method includes:

[0040] Step 101, detecting whether there is an object to be warned around the vehicle.

[0041] In one embodiment, the electric vehicle can detect objects to be detected around the vehicle based on cameras, radars or sonars; for example, the objects to be detected can be monitored based on cameras or radars of an ADAS system.

[0042] In one embodiment, the object to be detected includes a pedestrian, who can be a pedestrian on foot, a pedestrian driving a non-motor vehicle such as a bicycle, or a person driving ...

Abstract

The invention discloses a warning method, device and vehicle based on an electric vehicle, wherein the method includes: detecting whether there is an object to be warned around the vehicle; The risk factor of the vehicle to the object to be warned; if the risk factor of the vehicle to the object to be warned meets the set condition, a warning sound is played. The method, device and vehicle provided by the present invention can solve the problem of insufficient warning to pedestrians due to the low noise of smart electric vehicles, and intelligently warn pedestrians and drivers according to the level of danger of vehicles to pedestrians, which can reduce the impact of vehicles on the environment. Noise pollution, and help pedestrians to improve vigilance.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an electric vehicle-based warning method, device and vehicle. Background technique [0002] Electric vehicles are an important trend in the development of automobiles in recent years, and their popularity is getting higher and higher in society. Traditional gasoline vehicles have a large warning noise during driving, which can make pedestrians outside the vehicle notice the existence of the vehicle, while electric vehicles When the car is running at low speed, the sound is generally small, and it is difficult for pedestrians to notice. [0003] Along with the large-scale use of electric vehicle and hybrid vehicle power vehicle (pure electric mode), can bring very big safety problem. For example, when a pedestrian is walking on the road, suddenly a silent vehicle passes by, it will be surprising; especially for the hearing-impaired, this situation is very dangerous, if the pedestrian does...
