The present invention herein relates to a driving control apparatus of motorized scooter comprised of battery, driving unit, and motor, characterized in which the driving unit consists of at least a relay, a start-up and protective circuit, an under-voltage protective circuit, a power switch and speed control circuit, and a braking unit, that when the power switch and speed control circuit are on, and the relay is open, user may push the wheels of the scooter manually to drive the motor; when a set speed is reached and the relay is closed, the motor is driven directly, controlling the speed of the scooter, in addition, when the speed of the scooter is below a certain rate, the relay will be opened to stop the motor; at this time, the user may restart the motor by pushing the wheels of the scooter manually to move the scooter forward.

1. A kind of driving control apparatus of motorized scooter comprised of battery, driving unit, and motor, wherein the driving unit is connected with battery and supplies the power required by the motor, characterized in that said driving unit comprises at least a relay, a start-up and protective circuit, an under-voltage protective circuit, a power switch and speed control circuit, and a braking unit; and one end of said relay is connected with battery, that when the power switch and speed control circuit is on, and the relay is in open state, user can push the wheels of the scooter manually to drive the motor, causing the motor to generate counter electromotive force with its internal coil resistance and passive turning of armature, and when a set speed is reached, said counter electromotive force and the weak current it generates will actuate the start-up and protective circuit, and close the relay, so the current of the battery can pass through the relay to drive the motor directly; at the same time, the user can use the power switch and speed control circuit and the braking unit respectively to control the current input of motor, so as to control the acceleration, deceleration, and speed of the scooter; also, when the voltage output of battery to the motor is reduced significantly, the under-voltage protective circuit will open the relay immediately after receiving said voltage value, so the motor will stop turning due to the lack of current flow; at this time, the user may, depending on actual needs, use the braking unit to stop the scooter, or restart the scooter by pushing its wheels manually to let the motor turn passively; when the aforesaid set speed is reached, the relay is closed, so the current of battery may pass through the relay to drive the motor directly, thereby moving the scooter forward.
