Electric vehicle sound control device and method

Abstract

The invention provides a voice control device and method of an electric automobile. The voice control device comprises a camera module, a control module and an audio frequency processing module, wherein the camera module is used for acquiring surrounding images of the electric automobile, and sending the images to the control module in a real-time manner; the control module is used for receiving the images sent by the camera module, detecting objects in the images, selecting an object which is closest to the electric automobile and is the largest in the size in the detected objects, calculating the size of the selected object, comparing the size of the selected object with the size of a preset standard obstacle in the distance range to determine whether to broadcast an electric horn audio frequency signal or an external warning audio frequency signal, and according to the determined result, sending a corresponding audio frequency control command to the audio frequency processing module; and the audio frequency processing module is used for broadcasting the corresponding electric horn audio frequency signal or the corresponding external warning audio frequency signal according to the audio frequency control command sent by the control module. Through the adoption of the voice control device and method disclosed by the invention, the situations that the electric automobile is low in cost and light in weight are realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle voice control device and method. Background technique [0002] Because the sound of electric vehicles is relatively small when driving, it does not have a warning effect on pedestrians. Usually adopt the mode that outside warning device and electric horn are set on electric vehicle at present, remind pedestrian. [0003] The exterior warning device and the electric horn on the electric vehicle are two different components, and their function is to remind pedestrians. In this way, it is unfavorable for the light weight of the vehicle, the cost, etc., and the sound of the electric horn is usually not adjustable, which will bring some shock to pedestrians and cause environmental noise. Contents of the invention [0004] The invention provides an electric vehicle voice control device and method to reduce the voice control cost of the electric vehicle...
