Intelligent braking method and system for wheelchair

Abstract

The invention discloses an intelligent braking method and system for a wheelchair. According to the intelligent braking method and system for the wheelchair, a braking device is controlled to start braking after a braking instruction is received; whether the acceleration of the wheelchair is smaller than the acceleration of the wheels of the wheelchair is judged; and if the acceleration of the wheelchair is smaller than the acceleration of the wheels of the wheelchair, intermittent braking is executed with a set braking frequency. An inertial measurement device is installed on the wheelchair to measure the acceleration of the wheelchair; odometers are installed on the wheels of the wheelchair to measure the acceleration of the wheels of the wheelchair; when a user operates a brake controlto issue a braking instruction, a braking control module controls the braking device to perform braking, and whether the acceleration of the wheelchair is smaller than the acceleration of the wheels of the wheelchair is judged; if the acceleration of the wheelchair is smaller than the acceleration of the wheels of the wheelchair, it is indicated that the wheels decelerate quickly and the wheelchair itself decelerates slowly, such kind of condition most likely causes slip; intermittent braking is executed with the set braking frequency, so that a braking force can be controlled with the wheelsnot locked; and therefore, the slip can be avoided, the occurrence of dangers can be avoided, and the technical problem of a slip hidden hazard in the braking process of an existing wheelchair brake system can be solved.

Description

technical field [0001] The invention belongs to the technical field of wheelchairs, and in particular relates to a wheelchair intelligent braking method and system. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically handicapped and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. [0003] Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, braking device and seat. However, the braking system of current wheelchairs is mostly controlled manually. , but in the case of bad road conditions such as rainy and snowy days, the manual brake of the wheelchair often cannot meet the needs of the user, and it is easy to slip due to the brake lock, which brings unsafe hidden dangers. Contents of the invention [0004] The present application provides an intelligent...
