Embodiment 1
[0033] Such as Figure 1 to Figure 8 As mentioned above, a pedal load control system provided by the embodiment of the present invention, the pedal load control system of the present invention can be applied to electric bicycles, such as figure 1 As shown, the electric bicycle includes a front frame 19 , a rear frame 18 , a battery 13 , a generator 10 , pedals 21 , a main control unit 22 and an interface device 20 .
[0034] A generator 10 is provided in a front frame 19 , and pedals 21 are rotatably mounted on both sides of the generator 10 . When the driver rotates the pedal 21 , the rotational force of the pedal 21 is converted into electrical energy in the generator 10 , and the electrical energy of this generator 10 can be stored in the battery 13 .
[0035] In the front frame 19, the storage battery 13 and the main control unit 22 that store electric energy converted by the generator 10 may be disposed. The interface device 20 displays the driving status and riding dat...

The invention discloses a pedal load control method based on speed closed loop. The control method is used in a pedal load control system and includes the following steps: S10: Input the PWM with an initial fixed duty cycle as the base load of the pedal, and set the speed fluctuation coefficient. ; S20: Detect the current speed of the pedal as the target speed; S30: Detect the real-time speed of the pedal rotation at the next moment; S40: Determine whether the real-time speed of the pedal rotation at the next moment is zero; S50: Based on the judgment result, if the real-time speed is zero , then end the continuous pedaling mode; if the real-time speed is not zero, calculate the difference between the real-time speed and the target speed, and determine whether the difference is within the range set by the fluctuation coefficient; S60: Adjust the PWM duty according to the comparison result ratio or reset the target speed. The invention adjusts the pedal load by using a speed closed-loop method to prevent sudden changes in pedal speed, thereby providing a better riding and fitness experience.
Description
technical field [0001] The invention relates to the technical field of cycling control, in particular to a speed closed-loop-based pedal load control method. Background technique [0002] An ordinary electric bicycle, or pedelec, consists of an electric motor for rotating the wheels and a battery that powers the electric motor, and travels by means of the rotation of the electric motor's wheel. Ordinary electric bicycles are not equipped with pedals, and the speed of the vehicle is controlled by rotating the speed control handle to set different fixed gears; electric assist bicycles are equipped with torque sensors and motor controllers, which determine whether the driver needs a motor by detecting the user's pedal torque. Boost and the amount of boost needed. [0003] These e-bikes do not allow users to independently adjust the pedal load of the pedals. When the user reduces the pedal load for saving energy, or increases the pedal load for exercising, the actual demand ca...
