Embodiment Construction

[0024] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 Shown, this electric vehicle sound simulates sound method, comprises the following steps:

[0026] Step 1. Establish a sound sample file library: record the in-car sound of a traditional car in different states, and process and debug the original recorded sound files. The specific steps are as follows:

[0027] (1) Filter the original recorded sound files to remove noises other than the main order of the power system;

[0028] (2) Subjectively evaluate the sound and adjust the matching relationship between each order to meet the sound requirements of simulating a sporty or comfortable vehicle;

[0029] (3) In the real vehicle test, the sound pressure of the simulated sound is adjusted to satisfy the sound quality in the vehicle under different working conditions.

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...
