  "textContent": "A sound volume is adjusted in accordance with a volume adjustment coefficient ka calculated in accordance with a coefficient map with respect to an accelerator opening angle APO and another volume adjustment coefficient kv calculated in accordance with the coefficient map with respect to a vehicle speed V. The coefficient map with respect to vehicle speed V is set such that, as accelerator opening angle APO becomes higher, volume adjustment coefficient ka becomes larger in a sigmoid configuration. In addition, the coefficient map with respect to accelerator opening angle APO is set such that, as vehicle speed V becomes higher, volume adjustment coefficient kv becomes smaller in the sigmoid configuration.",
