Abstract

The vehicle (1) comprises an audio system for production of an engine noise. The audio system comprises an engine noise production unit (2,3), which is formed as a function of operating parameters of the vehicle to produce an engine noise signal, and a loudspeaker unit (5 to 8), which is coupled with the engine noise production unit. The loudspeaker unit is arranged in a wheel housing of the vehicle.

Description

technical field [0001] The invention relates to a vehicle with an acoustic device for generating engine noise, in particular an electric vehicle with an acoustic device for generating engine noise in the vehicle interior and / or for generating engine noise outside the vehicle. Background technique [0002] Electric vehicles or hybrid vehicles with at least one electric drive have very little engine noise compared to vehicles with an internal combustion engine. Persons outside the vehicle, such as passers-by or pedestrians, may thus only perceive the vehicle a little later. In addition, the engine noise of a vehicle having an internal combustion engine may cause the driver of the vehicle to perceive the current speed of the vehicle. Vehicles with electric drives do not provide such indirect speed information to the driver of the vehicle, so it may be difficult for the driver of the vehicle to estimate the travel speed. [0003] It is therefore known in the prior art to artif...
