Controlling method and controlling system of transport tool and electric wheelchair

Abstract

The invention discloses a controlling method and controlling system of a transport tool and an electric wheelchair. The controlling method comprises the steps that the direction and the size of external pressure suffered by the transport tool are collected through pressure sensing equipment, converted into a pressure signal, and then sent into an analyzing and controlling device; the analyzing and controlling device receives and analyzes the pressure signal, generates a controlling signal corresponding to the direction and the size of the external pressure and sends to controlling equipment; and the controlling equipment receives the controlling signal and controls the transport tool to moves toward the direction equivalent to the external pressure. The controlling mode is simple and conforms to natural habits of users and human body mechanics.

Description

technical field [0001] The invention relates to the technology in the field of transportation means, in particular to a control method and control system of the transportation means and an electric wheelchair. Background technique [0002] At present, the mainstream methods of controlling the power and direction of the vehicle are: [0003] 1) Represented by cycling bicycles, the steering wheel is mainly used for direction control, and the booster pedal is used to increase the accelerator and gear shift to achieve power output and transmission control; [0004] 2) Represented by electric unicycles, vehicles using gravity sensors use gravity-sensing gyroscopes for direction and power control; [0005] The above-mentioned control system of the means of transportation is more in line with the natural behavior of people, and the user can adopt it through simple learning. [0006] Then, the transportation tools commonly used in life, such as trolleys, do not have a good solutio...

AI Technical Summary

Problems solved by technology

[0007] 1) The power gear switch and the direction switch are set on the armrest car. The main disadvantages of this scheme are: (1) it is difficult to carry out fine-grained gear control; (2) it is contrary to the user's natural habits and human mechanics;

[0008] 2) The electric wheelchair uses a direction handle to control the direction. The main disadvantages of this scheme are: (1) it is not suitable for the accompanying personnel to use; (2) the feedback of natural obstacles, especially the resistance, is slow;

[0009] At present, luggage carts widely used in airports have good safety and automatic braking characteristics, and are suitable for scenes where the current airport road conditions are good and the resistance is small. The following disadvantages are identified: 1) The pressing action does not conform to the user's habits, so it still needs a learning process, although it is relatively short; 2) It is inconvenient to pull the push rod to run in reverse; 3) This solution is applied in complex road conditions, and the pressing Actions affect push actions

[0010] Generally speaking, the above-mentioned various operation methods are not simple enough, and the operation is relatively complicated. Those skilled in the art should study simpler operation methods that conform to the natural habits of users.
