The invention discloses a braking force distribution system for an electric bicycle, comprising: a drive circuit connected to a hub motor to adjust the running speed of the electric bicycle by controlling the rotation speed and steering of the hub motor; a speed sensor connected to the hub motor to collect the current running speed of the electric bicycle The pressure sensor collects the rider's pressure; the six-axis gyroscope collects the driving slope of the electric bicycle; the controller is connected to the speed sensor, the pressure sensor, the six-axis gyroscope and the drive circuit to And the current driving speed of the electric bicycle adjusts the parameters of the PID controller through fuzzy reasoning so that the slip rate of the electric bicycle is stable near the preset value. The braking force distribution system of the electric bicycle overcomes the potential safety hazards in the braking of the electric bicycle in the prior art, realizes the braking of the electric bicycle, and improves the safety of the braking while obtaining the shortest braking distance.
Description
technical field [0001] The invention relates to a braking force distribution system of an electric bicycle. Background technique [0002] Electric bicycles use electric energy as power, clean, green, and environmentally friendly, adapting to the development of the times. But since electric bicycles only have two wheels, they are not as stable as cars. During emergency braking under special road conditions such as rain and snow, the wheels of electric bicycles are prone to longitudinal slippage and even tail flicking. At this time, the adhesion between the tire and the ground is small, and there are certain safety hazards in driving an electric bicycle. When the electric bicycle brakes, the rotation speed of the wheel is: rω(k), and the actual speed of the body is v(k). The slip ratio of the electric bicycle when braking When the slip ratio is controlled at about 0.2, the longitudinal and lateral adhesion between the wheel and the ground is the largest, the shortest brak...
