US 2025/0153635 A1 · VIRTUAL ENGINE SIGNAL SYSTEM FOR VEHICLE AND METHOD OF CONTROLLING THE SAME

Abstract

A virtual engine signal system for a vehicle includes a first speaker provided on a front back beam of a vehicle, disposed to be directed toward a front side of the vehicle, and configured to output a virtual engine signal to the outside, a second speaker provided rearward of the first speaker, disposed to be directed toward a rear side of the vehicle, and configured to output a virtual engine signal to the outside, and a controller configured to transmit control signals to the first and second speakers so that the first and second speakers output the virtual engine signals in response to the control signals, the controller being configured to control the first and second speakers to adjust sound pressures of synthetic signals of the virtual engine signals of the first and second speakers at the front and rear sides of the vehicle.

Dependent claims

A virtual engine signal system for a vehicle, the virtual engine signal system comprising:

a first speaker disposed at a front back beam of the vehicle, the first speaker being oriented toward a front side of the vehicle and configured to output a first virtual engine signal to an outside of the vehicle;
a second speaker disposed rearward relative to the first speaker, the second speaker being oriented toward a rear side of the vehicle and configured to output a second virtual engine signal to the outside;
and
a controller configured to transmit first and second control signals to the first and second speakers to thereby cause the first and second speakers to output the first and second virtual engine signals in response to the first and second control signals, respectively,
wherein the controller is configured to control the first and second speakers to adjust sound pressures of synthetic signals of the first and second virtual engine signals of the first and second speakers at the front and rear sides of the vehicle, respectively.

A method for controlling a virtual engine signal for a vehicle, the vehicle including (i) a first speaker disposed at a front back beam of the vehicle, the first speaker being oriented toward a front side of the vehicle and configured to output a first virtual engine signal to an outside of the vehicle, and (ii) a second speaker disposed rearward relative to the first speaker, the second speaker being oriented toward a rear side of the vehicle and configured to output a second virtual engine signal to the outside, the method comprising:

transmitting first and second control signals to the first and second speakers, respectively;
outputting, by the first and second speakers, the first and second virtual engine signals in response to the first and second control signals, respectively;
and
adjusting sound pressures of synthetic signals of the first and second virtual engine signals of the first and second speakers at the front and rear sides of the vehicle, respectively.
