Abstract

The invention discloses a pedestrian warning device and a vehicle. The pedestrian warning device comprises a rain quantity sensor for sensing a rain quantity and forming a rain quantity signal, a sounding device for playing warning sound, and a controller for controlling at least one of volume and type of the warning sound based on the rain quantity signal. The pedestrian warning device can provide higher safety in rainy days. In other embodiments, the invention can further comprise a direction sensor or a microphone for controlling the warning sound based on a direction or noise.

Description

technical field [0001] The present invention relates to vehicle technology, more specifically, to a pedestrian warning device and a vehicle. Background technique [0002] Electric vehicles use green energy and have the advantage of being quiet while driving. For these reasons, electric vehicles are being used more and more widely. However, since the electric vehicle is very quiet during driving, pedestrians are not easy to perceive the approach of the electric vehicle. This is prone to unsafe factors. Especially in the process of low-speed driving of electric vehicles, it is more likely to cause safety problems. In the prior art, a low-speed driving warning device is used to give an audible warning when the electric vehicle is running at a low speed. However, in some special environments, for example, in the case of noisy environment (for example, there is high ambient noise around a driving electric vehicle), or in the case of rain, etc., under normal conditions An act...
