DECELERATION INFORMATION TRANSMISSION DEVICE AND DECELERATION INFORMATION TRANSMISSION METHOD

The present invention is intended to notify vehicle deceleration information more accurately. When an engine torque Te has a negative value, a sound volume adjustment coefficient kt is calculated depending on the engine torque Te, and a sound volume is adjusted depending on the sound volume adjustment coefficient kt. The sound volume adjustment coefficient kt is set to have a larger value as the absolute value of the engine torque Te becomes larger.
