System and method for active noise suppression in the vehicle interior

A system for active noise cancellation (ANC) (32) for use with a vehicle (10) having a vehicle body (14) defining a vehicle interior (12), and at least one electric drive mode, wherein the ANC system (32) comprising: a first set of audio speakers (19F, 19R) which are positioned outside of the vehicle interior (12); a second set of audio speakers (19I) positioned in the vehicle interior (12); and a controller (18) which is operable to: automatically generating a sound signal (20) during the at least one electric drive mode; generating processing of the acoustic signal (20) to thereby provide a modified sound signal (20A), wherein the modified sound signal (20A) representing a damped part of the sound signal (20) extending from a propagation of the acoustic signal (20) from the first set of loudspeakers (19F, 19R) by the vehicle body (14) and into the vehicle interior (12) yields; Generating a canceling signal (30) having an amplitude to that of the modified sound signal (20A) is proportional, and with a phase complementary to that of the modified sound signal (20A) is opposite; and Transmitting said sound signal (20) over the first set of audio speakers (19F, 19R) in a coordinated fashion with a transmission of the cancellation signal (30) over the second set of audio speakers (19I), whereby the modified sound signal (20A) in the vehicle interior (12 ) is suppressed.
