Problems solved by technology

However, in the prior art, the prompt tone cannot truly reflect the distance between the vehicle and the pedestrian
The inventors of the present invention realized that this would create false distance perception for pedestrians, which would also create a safety hazard

Abstract

The invention discloses a pedestrian warning device and a vehicle. The pedestrian warning device comprises a distance detecting sensor for detecting a distance from a pedestrian, a noise detecting sensor for detecting background noise to form a background noise signal, a controller for forming a warning tone signal based on the background noise signal, and a speaker for playing the tone based on the warning tone signal, wherein the controller also controls at least one of position and direction of the noise detecting sensor corresponding to the speaker, when the distance from the pedestrian is smaller than a preset distance, the noise detecting sensor is positioned in a sound radiation area of the speaker to form squeal. The pedestrian warning device can generate the squeal by a simple mode to cause the attention of the pedestrian so as to improve the safety.

Description

technical field [0001] The present invention relates to vehicle technology, more specifically, to a pedestrian warning device and a vehicle. Background technique [0002] With the popularization of electric vehicles, the problems of air pollution and environmental noise pollution caused by traditional fuel vehicles have gradually disappeared. However, this can also create problems because electric vehicles are too quiet. For example, in front of a vehicle, when a pedestrian walks with his back to the vehicle, it is often difficult for the pedestrian to notice that the vehicle is gradually approaching. This will pose a certain hidden danger to the safety of pedestrians. [0003] The solution in the prior art is to add an extra audio circuit to the electric vehicle. When the detection sensor in the vehicle detects that there are pedestrians around, the audio circuit will emit a corresponding prompt sound, thereby achieving the warning function. However, in the prior art, t...
