Abstract
The electric motorcycle (M) comprises a support frame, a rear wheel (RW), a front wheel (FW), an electric propulsion motor (E), an electronic control unit (2) for driving the electric motor (E) and a wheel anti-lock system (1) operatively connected to the control unit (2), the system (1) having detection means (18) of a slippage condition (SLP) of at least one of the wheels (RW, FW) and limiting means (19) operatively connected to the detecting means (18), able to receive at input at least a maximum regeneration torque value (RTMAX) of the electric motor (E) of the electric motorcycle (M) and able to limit the maximum regeneration torque (RTMAX) in case of detection of the slippage condition (SLP), wherein the system (1) comprises verification means (20) of the friction conditions of the wheels (RW, FW) on the road surface, in order to verify the presence or not of a high friction condition (HIGH_MU) or a low friction condition (LOW_MU), wherein the limiting means (19) are operatively connected to the verification means (20) and, in case of detection of the slippage condition (SLP), are able to limit the maximum regeneration torque (RTMAX) according to the high friction (HIGH_MU) o…
