A guide-blind vehicle control method based on guide-blind vehicle and human-vehicle coordination

Abstract

The embodiment of the present invention discloses a guide-blind vehicle control method in which a guide-blind vehicle and a human-vehicle are coordinated. The method includes: measuring the pulling force of the blind person on the guide-blind vehicle through a tension meter, and controlling the speed of the guide-blind vehicle according to the pulling force value; Set the camera to capture the images of the blind road and the blind person, and play the deviation correction prompt sound according to the positional relationship between the blind person and the blind road. By adopting the guide car and the guide car control method provided by the embodiments of the present invention, it is ensured that the speed of the guide car and the blind person is matched and the walking on the blind road is maintained, the travel experience of the blind person is optimized, and the guide car can better serve the Blind life.

Description

technical field [0001] The invention relates to the technical field of guide cars, in particular to a guide blind car control method of the guide car and the human-vehicle coordination. Background technique [0002] At present, due to the high training cost and the scarcity of domestic guide dogs, it is difficult to be widely used in the lives of blind people. Therefore, all kinds of intelligent guide-blind vehicles have emerged as the times require. Their low price, stability and reliability, and support for voice interaction make them more and more widely used. [0003] However, the development and design of almost all intelligent guide vehicles for the blind pay too much attention to the improvement of their own functions, such as blind lane detection, blind lane keeping, voice interaction, obstacle detection and avoidance, etc., lack of humanistic care for blind walking, such as the following two scenarios : [0004] If the speed of the intelligent guide car does not m...

AI Technical Summary

Problems solved by technology

[0004] If the speed of the intelligent guide vehicle does not match the walking speed of the blind, it cannot automatically adjust the speed to adapt to the walking rhythm of the blind;

[0005] If the blind person deviates from the blind path, the intelligent blind guide vehicle cannot detect it, and naturally it cannot guide the blind person to return to the blind path. The blind person can only rely on the blind guide stick to detect the blind path and correct the deviation
