Electric wheelchair power-assisted control system and power-assisted control method

Abstract

The invention relates to an electric wheelchair power-assisted control system and a power-assisted control method. The electric wheelchair power-assisted control system comprises a gyroscope sensor, afirst pressure sensor, a second pressure sensor, a handle controller and a motor driver, wherein the gyroscope sensor, the first pressure sensor, the second pressure sensor and the motor driver are all connected with the handle controller; the first pressure sensor is mounted in a position where left hand pushing contact of the electric wheelchair is performed, and the second pressure sensor is mounted in a position where right hand pushing contact of the electric wheelchair is performed; the handle controller is arranged on the wheelchair; and the motor driver is connected with a left wheeldriving motor and a right wheel driving motor of the electric wheelchair separately. According to the control system, the gyroscope sensor, the first pressure sensor, the second pressure sensor, the handle controller and the motor driver are arranged, so that the effect that the electric wheelchair can be pushed to go forward or backward in a labor-free manner in the case of no people around is achieved.

Description

technical field [0001] The invention relates to the field of electric wheelchairs, in particular to an electric wheelchair power assist control system and a power assist control method. Background technique [0002] With the development and progress of social civilization, the problem of population aging has become more and more prominent. Ensuring and improving the quality of life of vulnerable groups such as the elderly and the disabled has received widespread attention from people from all walks of life. Wheelchairs, as a means of transportation, have been favored by people with reduced mobility since their appearance. Traditional hand-pushed wheelchairs must be pushed and pulled by manpower. It's different, as long as the battery is fully charged, you don't need your family to accompany you all the time, and you can walk around by yourself, which is more convenient for your family and yourself. Therefore, the wheelchair has also developed from the initial single manual ...

AI Technical Summary

Problems solved by technology

Traditional electric wheelchairs can also rely on human push and pull to move forward, but it is necessary to turn off the power of the wheelchair control system and open the brake at the motor to allow the motor to run. It is more difficult to move forward, so it is necessary to propose an electric wheelchair that can be assisted in the human push-pull mode
