1. An electronic gear-shifting system with sound effects and display, adapted to be mounted on an electric motorcycle, and including:
an electronic shift unit outputting a shift signal;
an electronic clutch unit outputting a clutch signal;
a throttle position sensor outputting a throttle position signal;
a control unit connected to the electronic shift unit, the electronic clutch unit, and the throttle position sensor; and the control unit determining whether the electric motorcycle is switched to a target gear position according to the shift signal, the clutch signal, and throttle position signal to control a power motor of the electric motorcycle;
a sound effect controller connected to the control unit; and
a dashboard connected to the control unit and receiving communication data transmitted by the control unit; and the dashboard configured to display the target gear position, a virtual speed and a vehicle speed;
wherein the control unit further includes:
a vehicle controller connected to the electronic shift unit, the electronic clutch unit, and the throttle position sensor; the vehicle controller determining whether the electric motorcycle is switched to the target gear position according to the shift signal, the clutch signal, and throttle position signal, and generating a motor torque command corresponding to the target gear position; and
a motor controller connected to the vehicle controller to receive the motor torque command, and controlling the power motor of the electric motorcycle according to the motor torque command;
wherein the vehicle controller is preset with recharging current curves corresponding to different gear positions, and the recharging current curves include relationships between magnitudes of recharging currents and real speeds, and the recharging current in a low gear position is greater than the recharging current in a high gear position;
when the vehicle controller determines that a throttle position of the electric motorcycle is fully closed according to the throttle position signal, the vehicle controller outputs a recharging current command to the motor controller according to the recharging current curve corresponding to the gear position of the electric motorcycle, such that the motor controller outputs a recharging current to a battery pack.
