Abstract

The invention discloses a sound prompting device for pedestrians in an electric vehicle and a realization method thereof. The device comprises a speaker and a controller, and the speaker and the controller are connected through an audio transmission line. The sensor is connected. The electric vehicle pedestrian sound prompting device can effectively remind the surrounding pedestrians that there are electric vehicles approaching, so as to avoid the occurrence of accidents caused by the pedestrians not being able to hear the sound of the electric vehicles. Moreover, the present invention can effectively remind pedestrians, greatly increasing the possibility of pedestrians hearing the sound.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an electric vehicle pedestrian sound prompting device and a realization method. Background technique [0002] At present, because electric vehicles or hybrid vehicles emit very little noise when running in pure electric form at low speed, they cannot effectively attract pedestrians' attention to the approaching vehicles, which may easily cause accidents. Chinese Patent Publication No. CN101565017A, published on October 28, 2009, an invention patent titled "Electric Vehicle with Driving Reminder Device and Working Method thereof" discloses an electric vehicle with driving reminder device, including an electric drive system , the electric drive system includes a drive and control circuit, a speed regulating operating mechanism and a rotating system, and is characterized in that it is equipped with a driving sound and / or vibration rule for simulating the driving sound and / or vibrati...
