Abstract
Traction control for a motorcycle including a driving wheel speed sensor and a driven wheel speed sensor. An ECU controls an engine on the basis of a corrected slip signal obtained by subtracting a low frequency component of a pre-correction slip signal from the pre-correction slip signal. The pre-correction slip signal is obtained by subtracting a speed of a front wheel detected by the driven wheel speed sensor from a speed of a rear wheel detected by the driving wheel speed sensor.
