Abstract
A plurality of speakers disposed in a front and a rear of a passenger and a controller configured to control a sound field in a vehicle cabin by individually driving the plurality of speakers. The controller is configured, when an operation input for changing an acceleration/deceleration behavior of the vehicle is made, to set a normative acceleration/deceleration depending on the operation input, to detect an actual acceleration/deceleration, and to displace the sound field in the vehicle cabin in the direction of a change in the actual acceleration/deceleration behavior of the vehicle depending on the deviation of the actual acceleration/deceleration relative to the normative acceleration/deceleration. That is, a change of an acceleration/deceleration behavior depending on the operation input is rendered before the change of the actual acceleration/deceleration behavior of the vehicle.
