PROBLEM TO BE SOLVED: To quickly control informing sound according to speed variation of a vehicle. SOLUTION: The control device 14 determines an operation amount of an accelerator pedal 18 per unit time (0.1 second) based on a detection value from an accelerator operation sensor 20 for detecting an operation amount of the accelerator pedal, and controls the informing sound generated from a speaker 12 based on the operation amount of the accelerator pedal 18 per unit time and the detection value from a vehicle speed sensor 16. Accordingly, when the vehicle 10 performs rapid starting and rapid acceleration by operation of the accelerator pedal 18, control for generating or increasing the informing sound can be performed without lagging behind the variation of the vehicle speed.
