  "textContent": "A road surface determination apparatus includes an acceleration detector and a road surface determination unit. The acceleration detector is configured to detect an acceleration of a vehicle body or a vibration transmission member configured to transmit vibration from a tire to the vehicle body. The road surface determination unit is configured to determine a condition of a surface of a road, using a determination value obtained by extracting a component of a predetermined frequency band from the acceleration detected by the acceleration detector and integrating the component.",
