Four-wheel somatosensory vehicle braking method, device, system and four-wheel somatosensory vehicle

Abstract

A four-wheel motion-sensing car braking method comprises the steps that first quadrant pressure of a first wheel of a four-wheel motion-sensing car, second quadrant pressure of a second wheel of the four-wheel motion-sensing car, third quadrant pressure of a third wheel of the four-wheel motion-sensing car and fourth quadrant pressure of a fourth wheel of the four-wheel motion-sensing car are obtained; the current speed of the four-wheel motion-sensing car is obtained; a pre-braking instruction is obtained according to the first quadrant pressure, the second quadrant pressure, the third quadrant pressure, the fourth quadrant pressure and the current speed; a reverse pulse signal is controlled to be output to the motor driving end according to the pre-braking instruction; and when the current speed is lower than or equal to a preset braking speed, outputting of the reverse pulse signal is controlled to be stopped. The invention further provides a four-wheel motion-sensing car braking device and system and the four-wheel motion-sensing car. The high speed of a motor can be rapidly decreased after braking is conducted till the motor is in a locked state by outputting the reverse pulsesignal, the braking time and distance can be shortened, and the manipulation safety is enhanced.

Description

technical field [0001] The invention relates to the field of somatosensory vehicles, in particular to a somatosensory vehicle braking method, device, system and a four-wheel somatosensory vehicle with the somatosensory vehicle braking system. Background technique [0002] The somatosensory vehicle in the prior art is also called a balance vehicle, and its operating principle is mainly based on a basic principle of "Dynamic Stabilization", that is, the automatic balancing ability of the vehicle itself. The built-in precision solid-state gyroscope (Solid-State Gyroscopes) is used to judge the posture state of the car body, and the precise and high-speed central microprocessor calculates the appropriate command, and then drives the motor to achieve the balance effect. [0003] With the rapid development of smart life today, various brands of somatosensory cars emerge in endlessly. No matter in the fields of entertainment, transportation, business, leisure and fitness, somatose...

AI Technical Summary

Problems solved by technology

Most of the latest four-wheel somatosensory vehicles on the market brake through ordinary forward speed deceleration to achieve braking. Due to inertia, the braking time is too long and the braking distance is too large

Undoubtedly, the braking system is very important to the running car body. Failure or lag of the brakes will lead to the possibility of accidents, which will bring huge hidden dangers to the safety of drivers.
