Intelligent wheelchair and control method

Abstract

The invention discloses an intelligent wheelchair and a control method. The control method includes: detecting state of the wheelchair to acquire at least one state parameter which includes one or multiple of speed of the wheelchair and acceleration of the wheelchair; when any state parameter reaches a corresponding preset threshold value, winding a braking line. Timely and active braking intervention can be realized when any state parameter of the wheelchair is abnormal, so that using safety of the wheelchair is improved, and safety of users is protected.

Description

technical field [0001] The present disclosure generally relates to the field of medical equipment, and specifically relates to an intelligent wheelchair and a control method. Background technique [0002] Wheelchairs are equipment and devices used by people with disabilities, and even important auxiliary tools for such people to participate in social activities. Existing wheelchairs are generally driven by electric or human power, but when wheelchairs are in use, due to road conditions, There will be more potential safety hazards. For example, the speed of the wheelchair will increase when going downhill, which will cause the center of gravity of the user on the wheelchair to change. , when observing the front of the road ahead, the field of vision will have some limitations. When avoiding obstacles, the brakes will not be timely due to the negligence of the user's response, and sudden braking will also easily cause the user to be injured; It can be seen that the anti-skid ...

When avoiding obstacles, the brakes will not be timely due to the negligence of the user's response, and sudden braking will also easily cause the user to be injured; The anti-skid system or anti-rollback system of the electric wheelchairs sold is often relatively simple, usually simple anti-skid small wheels, and the adjustment range is often limited in places with large slopes
