Method and device for sound simulation and sound production of electric vehicle

Abstract

The invention discloses a method and a device for sound simulation and sound production of an electric vehicle. The method includes sound mode selection, real-time vehicle information acquisition, signal processing of a control unit and sound file play. The control unit is connected with a signal acquisition unit, a sound mode selection switch and an in-vehicle sound player; the control unit is used for receiving signals of a rotational speed sensor, a throttle sensor and a vehicle speed sensor, and selecting a signal transmitted from a movement mode switch or a comfort mode according to a driver and passengers to control the in-vehicle sound player so as to enable the in-vehicle sound player to produce sound. By the method and the device, driving sound of a motorized vehicle under the same state can be simulated accurately, sound types are selected individually, and the problems of low noise in the vehicle, single sound and unpleasant driving feeling of the electric vehicle are solved.

Description

technical field [0001] The invention relates to an electrical system of an electric vehicle, and more particularly relates to a sound simulation method and device for an electric vehicle. Background technique [0002] With the country's vigorous promotion of new energy vehicles, more and more consumers have personally experienced the different charms brought by electric vehicles. There is a big difference between electric vehicles and traditional vehicles. In addition to the different energy sources, the most intuitive feeling for consumers is that the sound of electric vehicles is small, and the interior of the cab is very quiet. During low-speed driving, there is almost no obvious sound. This frees NVH engineers from having to worry about noise reduction in EVs. But everything has two sides. Because the sound in the car is smaller than that of traditional cars, the driver and passengers cannot intuitively judge the speed of the vehicle based on the size of the sound. In a...
