Bicycle speed control method and system for electric bicycle, and electric bicycle

Abstract

The embodiment of the invention provides a bicycle speed control method and system for an electric bicycle, and the electric bicycle and belongs to the technical field of automatic control. The problem that the bicycle is accelerated suddenly due to misoperation of the electric bicycle is solved. The bicycle speed control system comprises an acceleration sensor, a bicycle speed sensor and a controller. The acceleration sensor is used for sensing the acceleration of the electric bicycle in the traveling direction and outputting an acceleration signal identifying the magnitude of the acceleration; the bicycle speed sensor is used for sensing the traveling speed of the electric bicycle and outputting a speed signal identifying the magnitude of the traveling speed; and the controller is used for obtaining the acceleration signal and the speed signal, and if the speed signal is smaller than or equal to a bicycle speed threshold value and the acceleration signal is larger than an acceleration threshold value, the controller cuts off electricity supplying of a motor of the electric bicycle. The bicycle speed control method and system for the electric bicycle are suitable for treating thesudden changing process of the bicycle speed of the electric bicycle.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a speed control method and system of a motor cycle and the motor cycle. Background technique [0002] Motorcycles are generally divided into two types. One is to control the speed of the vehicle through the handle. When the user turns the handle, the controller will give the corresponding current according to the angle of the handle to drive the motor to rotate at the corresponding speed. The other is to control the speed through the pedal. The cadence sensor controls the speed of the vehicle. When the user steps on the pedal, the pedal drives the cadence sensor on the bottom bracket shaft. The cadence sensor outputs a corresponding signal to the controller according to the pedaling speed of the user, and the controller controls the motor speed according to this signal. . For the above two cases of motor cycle misoperation, for example, when the user pushes the motor c...
