Multi-attitude adjusting electric wheelchair control system

Abstract

The invention discloses a multi-attitude adjusting electric wheelchair control system, which comprises a manual operator module, a CAN communication module, a controller module, a differential motor driving module, an electric push rod driving module and a power supply module, wherein the manual operator module is used for carrying out operation control on a wheelchair; the manual operator module and the controller module are communicated through the CAN communication module; the controller module controls the differential motor driving module to drive a motor to operate in a differential manner and controls the electric push rod driving module to drive an electric push rod to carry out attitude adjustment; and the power supply module is used for providing power for the manual operator module, the controller module, the CAN communication module, the differential motor driving module and the electric push rod driving module. Through the electric wheelchair control system, problems of electric wheelchair operating lever zone control, electric wheelchair multi-attitude adjustment and motor position information feedback monitoring can be solved, and the electric wheelchair is enabled to have the characteristics of functional diversity, acceleration and deceleration smoothness, turning operation comfort and safety and closed-loop smoothness.

Description

technical field [0001] The invention relates to a control system of an electric wheelchair, which is used for controlling the posture adjustment of the electric wheelchair and the differential operation of dual motors of the wheelchair. Background technique [0002] my country's aging society is developing rapidly.
