The traction control system described in a Piaggio patent includes a map generated when a loss of traction occurs. The throttle position (θ) and slip (λ) at that time are noted (as θhold and λhold respectively). Proportionally more or less slip is allowed, based on a maximum permissible slip value (λmax) at full throttle and no slip at closed throttle, giving the rider continued control ver the slip at each occurrence.
