Foot-controlled electric balance vehicle

Abstract

The invention relates to the field of steering calculation of a two-wheel self-balancing vehicle and discloses a foot-controlled electric balance vehicle. The method comprises the steps that pressuredata borne by different portions of the pedal positions of the balance vehicle are detected and output, steering of the balance vehicle is controlled by depending on pressure difference information generated by pedaling at different positions when people steer naturally, and safety hidden danger such as misjudgment of steering and straight going and misjudgment of steering range under various actual circumstances of random swinging of the gravity center, leaving of the single foot from the balance vehicle and the like can be effectively avoided. Meanwhile, when the single foot is on the vehicle, the balance vehicle does not swing, and safety and stability of boarding are enhanced.

Description

technical field [0001] The invention relates to the field of balance vehicles, in particular to a foot-controlled electric balance vehicle. Background technique [0002] Two-wheeled self-balancing vehicles are a typical unbalanced, non-linear, and under-actuated system. There are currently three main steering control methods for two-wheeled self-balancing vehicles: [0003] The first is to detect the change of human body posture through the gyro instrument. This method realizes the turning operation of the balance car through the structure of the center of gravity and the rotation axis, but this structure has several disadvantages: [0004] 1. Gyro devices are greatly affected by noise and temperature, requiring more complex algorithms to ensure the reliability of the system, increasing the cost of the control module, and requiring regular calibration, which increases the difficulty of the user's operation; [0005] 2. When going straight, there will be left and right swing...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a recognition method for controlling the turning of electric balance vehicles by man-made changes in foot control pressure, which effectively solves the problem of turning and turning in various practical situations (such as random swinging of the center of gravity, leaving the balance car with one foot, etc.). Application problems such as misjudgment of going straight and misjudgment of turning width
