Abstract

The invention relates to an intelligent wheelchair vehicle based on a drive-by-wire technology and a control method. According to the technical scheme, the control method includes the step of system initialization, wherein fault states of all hub motors are detected to determine a corresponding driving mode, if modules where the four hub motors are located all work normally, a system enters a four-wheel drive mode, if the module where a certain hub motor of front wheels is located breaks down but the modules where the two hub motors of rear wheels are located work normally, the system enters a rear-wheel drive mode, and if the module where a certain hub motor of the rear wheels is located breaks down but the modules where the two hub motors of the front wheels are located work normally, the system enters a front-wheel drive mode; the step of drive control such as going straight, turning and braking. The intelligent wheelchair has the advantages that the drive-by-wire technology is adopted, the manipulating mechanism and the actuators are connected through wires to replace conventional mechanical connection, the structure is simplified, the component arrangement is flexible, control is rapid and flexible to carry out, the wheelchair travels intelligently, and the indoor and outdoor action ability of old people and patients with dyspraxia is improved.

Description

technical field [0001] The invention relates to an intelligent wheelchair and a control method, in particular to an intelligent wheelchair and a control method based on wire control technology. Background technique [0002] With the increase in the aging level of Chinese society and the increase in the number of people with mobility disabilities caused by traffic accidents and diseases, the requirements for the quantity and quality of wheelchairs are also increasing. Electric wheelchairs can meet the requirements of people with mobility disabilities to travel within a certain range, and improve their self-care ability to a certain extent. [0003] There are already some patents on the structure and control methods of electric wheelchairs. For example, the published patent "Omnidirectional Intelligent Electric Wheelchair" (Chinese Patent Publication No.: CN202568664U) has omnidirectional movement capabilities such as lateral and oblique movement and greater mobility than con...
