Abstract

Embodiments of the present invention provide an electric vehicle sound control device and method, which belong to the technical field of electric vehicles. The electric vehicle sound control device includes: a working parameter acquisition unit, used to collect the first vehicle working parameters about the electric vehicle; a sound wave sound determination unit, used to determine the corresponding The first order sound wave sound of the first vehicle operating parameter, wherein the sound wave sound library stores multiple groups of order sound mapping relationships between multiple vehicle operating parameters and multiple order sound wave sounds of the reference engine; The sound control unit is used to generate a target masking sound based on the first order sound wave sound and output the target masking sound to the car to mask the motor whistling noise in the car, and / or generate a target masking sound based on the first order sound wave sound to generate the target warning sound and output the target warning sound to the outside of the vehicle. Therefore, calling a certain order of sound waves can improve the howling sound of the motor in the car, and can also realize the sound warning outside the car.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle sound control device and method. Background technique [0002] With the country's strong support for new energy technologies, new energy vehicles have been vigorously promoted. Since pure electric vehicles are driven by motors and do not have engines, on the one hand, along with the overall improvement in the quality of new energy vehicles, the quietness of the car interior has been improved. In the car, it will greatly increase the irritability of passengers; on the other hand, since the new energy vehicle has no engine, there is no sound of intake and exhaust, and the lack of roar of the vehicle makes it difficult to be distracted by pedestrians on the road. It is perceived by the vehicle and has a greater potential safety hazard. [0003] In view of this, there are mainly two improvement schemes for the motor whistling noise in the car provided ...
