Beschreibung
Zusammenfassung:	A ground speed detection device for a vehicle includes a wheel speed sensor configured to detect a rotational speed of a wheel, a second storage section having stored a radius of the wheel corresponding to a bank angle, and a ground speed calculator configured to calculate a ground speed during cornering. The ground speed calculator extracts the radius of the wheel corresponding to a bank angle detected by a bank angle detection device, from the second storage section, and calculates the ground speed during cornering from the extracted radius of the wheel and the rotational speed of the wheel detected by the wheel speed sensor.
