Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] A method for controlling the state of a power-assisted bicycle by using a detection device, wherein the detection device is suitable for detecting the pedal output torque and rotational speed parameters of the rider when riding the power-assisted bicycle, so that the controller can accurately control the torque of the hub motor, Output value such as speed. Such as figure 1 As shown, the power-assisted bicycle includes a vehicle body 1, an in-wheel motor (not shown in the figure) arranged on the rear wheel, a pedal 11 arranged on the central axis of the vehicle body, a crankset 12, and a wheel around the crankset and the rear wheel. The transmission chain 2 on the flywheel 13, and the controller that can control the output parameters of the hub motor. The vehicle body needs to be equipped with a detection device to sense the tension for...

The invention discloses a method for controlling the state of a power-assisted bicycle by using a detecting device. When riding is started, a tension sensor is used for sensing the tension of a tensioning section of a transmission chain to obtain a tensioning force signal and the tensioning force signal is inputted into a controller; a speed sensor is used for sensing the moving speed of the transmission chain to obtain a moving speed signal and the moving speed signal is inputted into the controller; the controller enables a hub motor for driving a rear wheel to rotate to output a corresponding torque based on the tensioning force signal and the output torque of the hub motor is adjusted based on the change value of the tensioning force signal; and meanwhile, the controller enables the hub motor to output a corresponding rotation speed according to the moving speed signal and the output rotating speed of the hub motor is adjusted based on the change value of the moving speed signal. According to the invention, the power assisting function of the hub motor matches the riding state of the rider and thus the rider can control the riding speed of the vehicle according to the own subjective will, so that the effort is saved and the good exercise effect is realized.
Description
technical field [0001] The invention relates to the technical field of electric power-assisted bicycles, in particular to a control method capable of controlling the state of the power-assisted bicycle according to the riding state and road conditions. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, electric power-assisted bicycles, which are mainly driven by manpower and supplemented by electric power assistance, have been gradually popularized and promoted. Yes, the speed of the hub motor is not controlled by the cyclist by controlling the speed control switch arranged on the handle, but the speed of the hub motor of the electric power-assisted bicycle is controlled by a controller. When the controller receives signals such as pedal speed and torque output by the sensor, or the state of the vehicle, it can automatically control the working state and output torque of the in-wheel motor. That is to say, the cy...
