Problems solved by technology

Generally speaking, a three-axis accelerometer can be used to measure the slope angle, but when there is a sudden push by an external force, the acceleration will often change too much instantaneously, so the estimated slope angle will be affected
Furthermore, because the slope angle is the judgment condition for the assist or resistance provided by the electric walker, when the slope angle is judged incorrectly, the electric walker will suddenly provide wrong assist or resistance, which will cause discomfort or even danger to the user.
In addition, the three-axis data of the gyroscope can also be used to correct the influence of external forces. However, the gyroscope will have the problem of accumulating errors. The result of accumulating angle errors over time makes the aforementioned problems unable to be effectively solved.

Embodiment Construction

[0021] Certain terms are used throughout the specification and preceding claims to refer to particular elements. Those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The scope of this specification and the preceding claims does not use the difference in name as the way to distinguish components, but the difference in function of the components as the basis for distinction. "Include" or "comprising" mentioned throughout the specification and the preceding claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection me...

Abstract

A control method for an electrical walker is provided. The control method includes measuring a plurality of slope angle values, determining a correction parameter value according to the plurality of slope angle values and generating a corrected driving force value according to the correction parameter value and an original driving force value, so that the influence of external force can be avoided, and the use comfort can be improved.

Description

technical field [0001] The invention relates to a control method and an electric walking aid, in particular to a control method and an electric walking aid which can avoid the influence of external force and can improve the comfort of use. Background technique [0002] A walker is one of the common mobility aids. The walker can provide additional support when the user is standing or walking, so as to maintain balance or stability and ensure the safety of the user. Furthermore, current electric walkers (or called electric walkers) are usually equipped with a power source to assist in moving, so that users can move without exerting too much force by pushing and pulling the electric walker , especially for users with injured or weak arms or shoulders. [0003] Electric walking aids can give users assistance or resistance when going up and downhill, so it is very necessary to accurately judge. Generally speaking, a three-axis accelerometer can be used to measure the slope angl...
