Example Embodiment

[0021] Example: A voice prompt device for pedestrians in an electric vehicle, the circuit principle connection diagram is as follows figure 1 As shown, the speaker 2 and the controller 1 are included. The speaker and the controller are connected by an audio transmission line 7. The speaker is arranged at the front of the electric vehicle, and the sound frequency from the speaker includes a frequency lower than 1600KHz. The controller is also connected to the vehicle speed sensor 3, the gear position sensor 4, the radar sensor 5 and the motor 6. The surface of the speaker is provided with a circular baffle, which is also connected to the motor; the structure diagram of the circular baffle is as follows figure 2 As shown, the circular baffle 8 is provided with two arc-shaped openings 9, and the two circular arc-shaped openings are symmetrical to the center of the circular baffle. The arc of the arc-shaped opening is 90°. The front part of the electric vehicle is provided with t...

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...
