Power mode switching system of electric motorcycle

Abstract

The invention provides a power mode switching system of an electric motorcycle, which comprises an accelerator opening degree sensor, a motor controller, a whole motorcycle controller and an operating device, the accelerator opening degree sensor generates an accelerator opening degree signal, the motor controller generates a motor rotating speed signal, and the whole motorcycle controller generates a motor rotating speed signal. A plurality of power meters and a plurality of power modes are stored in the vehicle control unit, each power mode adopts one power meter, at least one operation device is connected with the vehicle control unit and used for switching the power modes, and the vehicle control unit controls the power meters according to the opening degree of an accelerator and the actual rotating speed of a motor of the electric motorcycle. The motor controller receives a current power mode, obtains a corresponding motor torque from a power table corresponding to the current power mode, and outputs a motor torque signal to the motor controller according to the motor torque, and the motor controller controls the torque output of the motor according to the motor torque signal.

Description

technical field [0001] A power mode switching system, especially a power mode switching system of an electric motorcycle, for users to switch the electric motorcycle to a suitable power mode according to road conditions and riding needs. Background technique [0002] Motorcycles are one of the most popular means of transportation in today’s society. In addition to bringing convenience to people’s transportation, they also promote the prosperity of the logistics industry. Generally, motorcycles obtain power from burning oil. However, with the popularity of motorcycles, Exhaust gas emitted by motorcycles has gradually become one of the sources of air pollution and has an impact on the global greenhouse effect. In view of this, manufacturers of automobiles and motorcycles have begun to devote themselves to research and development of power supply from fossil energy to renewable energy. Electric motorcycles that replace traditional fuel-efficient motorcycles have emerged as the ...
