摘要：
An apparatus for calculating a wheel speed is described herein which includes a tire force sensor, a time measurement unit, an angular velocity calculation unit and a wheel speed calculation unit. The tire force sensor outputs a signal in accordance with an amount of modification of a bearing. The time measurement unit measures a time interval between peak values of the signal output from the tire force sensor. The angular velocity calculation unit calculates an angular velocity by dividing an angle between balls positioned within the bearing by the time interval measured by the time measurement unit. The wheel speed calculation unit calculates the wheel speed by multiplying a distance from a center of the bearing to a center of the ball by the angular velocity calculated by the angular velocity calculation unit.
