Abstract

A method for controlling the advancing speed in electrical propelled scooter allows to control an electric scooter intuitively, practically and without creating any difficulty to the driver and comprises the steps of setting a target speed (vt); detecting a real speed (vr) of the electric motor (M) of the scooter; comparing the real speed (vr) with the target speed (vt); operating the electric motor (M) of the scooter so as to approach said target speed (vt), by means of a PID controller (CPID), the value of the proportional gain (Kp) thereof being variable according to a velocity error (εv) obtained by the step of comparing the real speed (vr) and the target speed (vt).

Abstract

A method for activating and controlling a parking brake system in electrically propelled scooters allows to provide an effective parking brake, that at the same time can be operated simply and rapidly and comprises the steps of: generating an activation control (SP); detecting speed and/or acceleration of the scooter following to the reception of said activation control (SP); keeping the electric motor (EM) of the scooter stationary when the speed and/or the acceleration are substantially equal to zero at least for a predetermined stopping time (ts).

Abstract

A device for operating a regenerative braking system in electrical propelled scooter allows to coordinate the regenerative braking action with the mechanical one, using a practical activation system, intuitive and easily operable by the driver and comprises means for detecting a mechanical braking (21, 55), apt to generate a braking signal (SB) upon the operation of a mechanical brake control (20), and a control unit (CU) for switching the operation del electric motor (M) so as to operate as an electric generator, the detecting means (21, 55) being associated to the control unit (CU), wherein upon receiving said braking signal (SB) the electric motor (M) is switched as a generator, so as to recharge a battery pack (BP) and generate an electromagnetic braking torque.
