Voice warning system for electric vehicle

Abstract

The invention discloses a voice warning system for an electric vehicle, which comprises an audio output unit, a speed regulating unit for triggering speed or acceleration of the electric vehicle, and an audio electronic unit. The voice warning system is characterized in that the audio electronic unit generates musical sound current corresponding to the preset speed or acceleration of the electric vehicle according to a regulating signal value of the speed regulating unit, so as to drive the audio output unit to generate sound warning. The voice warning system has the following beneficial effects: the voice warning system can generate corresponding warning tone automatically and continuously when the vehicle is driven; when the vehicle is sped up, the warning tone can be loud; when the vehicle is accelerated, the tone can be louder; but when the environment volume is lower, the warning tone can be regulated according to the environment situation so as not to interrupt people; meanwhile, the device can be flexibly processed to be convenient for the user to operate, so that the driving safety is improved greatly; and the voice warning system is simple, practical, and strong in adaptability.

Description

technical field [0001] The invention relates to a sound warning system for an electric vehicle, in particular to a sound warning system for an electric vehicle approaching pedestrians and the like. Background technique [0002] There are many kinds of electric vehicles on the market at present, which have been widely popularized with the characteristics of energy saving and environmental protection. Its noise level is also very low, but precisely because its noise is much lower than that of traditional cars, it is difficult for traffic participants to detect it in time when driving fast, and the resulting dangers and accidents are too numerous to enumerate. Although most of the existing vehicles are provided with electric horns, this is a passive sound reminder.
