Embodiment 1

[0051] refer to figure 1 , an auxiliary intelligent wheelchair automatic entry and exit vehicle system described in this embodiment includes: an electric wheelchair system and two sets of auxiliary ramp plate mechanisms symmetrically arranged on the chassis of the vehicle frame;

[0052] Wherein, the electric wheelchair system includes: an electric wheelchair main body, a front auxiliary camera, a rear auxiliary camera, a touch display screen, a wheelchair processor chip, a ranging sensor, and a wheelchair signal transmitting and receiving device respectively arranged on the electric wheelchair main body. The wheelchair processor chip is arranged inside the touch screen and is electrically connected to the touch screen. The wheelchair processor chip is used to display position information, image information, control instructions, etc. on the touch screen. To send the received driver's touch signal to the wheelchair processor chip; the wheelchair signal transmitting and receivi...

Embodiment 2

[0058] refer to Figure 6 , Figure 7 , a control method for controlling the above-mentioned auxiliary intelligent wheelchair automatic entry and exit vehicle system, the control method includes: a step of getting on the car and a step of getting off the car:

[0059] The details of the boarding control method are as follows:

[0060] Step S1: When the main body of the electric wheelchair is close to being installed on the auxiliary ramp mechanism, use the front and rear auxiliary cameras and distance measuring sensors to identify the auxiliary ramp mechanism and transmit the identified signal to the vehicle processor chip for processing;

[0061] Step S2: The wheelchair processor chip sends the signal for releasing the auxiliary ramp plate mechanism to the wheelchair signal transmitting and receiving device and sends the signal through the wheelchair signal transmitting and receiving device;

[0062] Step S3: The vehicle information receiving and transmitting device receive...

Embodiment 3

[0081] First, the auxiliary ramp plate mechanism is installed on the deck of the ship. When the ship is docked, the boarding control method and the dismounting control method in Embodiment 2 are used to realize the main body of the electric wheelchair getting on and off the ship.

Abstract

The invention relates to the field of intelligent wheelchairs, in particular to a system for assisting an intelligent wheelchair in automatically entering and exiting a vehicle and a control method thereof. The system for entering and exiting the vehicle comprises an electric wheelchair system and two sets of auxiliary slope board mechanisms symmetrically arranged on a frame chassis or a ship deck; the electric wheelchair system includes an electric wheelchair body, a front auxiliary camera, a rear auxiliary camera, a touch display screen, a wheelchair processor chip, a distance measuring sensor and a wheelchair signal transmitting and receiving device, wherein the front auxiliary camera, the rear auxiliary camera, the touch display screen, the wheelchair processor chip, the distance measuring sensor and the wheelchair signal transmitting and receiving device are separately disposed on the electric wheelchair body. The system for assisting the intelligent wheelchair in automatically entering and exiting the vehicle and the control method thereof has the advantages that the process of driving the electric wheelchair body into the vehicle is smarter and more convenient, collision isavoided and safety is ensured in the process of getting on and off the auxiliary slope board mechanisms, and the positioning of the electric wheelchair body on the vehicle is more accurate, so that itis more convenient for people with disabilities on lower limbs to get on and off vehicles, boats and other vehicles when traveling.

Description

technical field [0001] The invention relates to the field of intelligent wheelchairs, in particular to a system for assisting intelligent wheelchairs in and out of vehicles automatically and a control method thereof. Background technique [0002] With the intensification of the aging of modern society and the improvement of people's quality of life, a series of social problems of people with lower limb disabilities and elderly people are becoming increasingly apparent. In order to meet the travel needs of people with lower limb disabilities, electric wheelchairs are gradually popularized. In the process of traveling in a wheelchair, people often encounter the need to enter and exit vehicles, ships and other vehicles in a wheelchair. However, the prior art does not well solve the problem of how the disabled can autonomously drive the electric wheelchair in and out of vehicles, ships and other vehicles. [0003] For example, the patent (CN201410033301) provides a car getting ...
