Problems solved by technology

[0003] However, for intelligent control mobile devices such as self-balancing vehicles, robots or self-driving vehicles, it is easy to imagine that although they are all equipped with a braking system, when braking in a fast-moving state, there will be a long braking distance. Risk of easy collision with obstacles, thereby reducing its safety performance

Embodiment Construction

[0062] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments. It should be understood that the following examples are only used to explain and illustrate the present invention, but are not intended to limit the technical solution of the present invention.

[0063] At present, in the field of intelligent mobile technology, although they are all equipped with a braking system, when they brake in a fast-moving state, there will be a long braking distance and the risk of bumping into obstacles. Take the self-balancing car (also called somatosensory car, thinking car, and camera car) as an example. The self-balancing car mainly uses the gyroscope and acceleration sensor inside the car body to detect changes in the attitude of the car body, and uses the servo control system to accurately drive the motor to make corresponding adjustments to maintain the dynamic balance of the ...

Abstract

The invention relates to an autonomous obstacle avoidance method, an autonomous obstacle avoidance device and an autonomous obstacle avoidance system applied to the field of intelligent mobile technology. The autonomous obstacle avoidance method comprises: establishing a front obstacle information map, assigning a value to each pixel based on the detection results of at least two different distance detection sensors on the coverage area of the N*N grid map, and planning a path according to the assigned values. The autonomous obstacle avoidance device comprises a map establishing module, an assigning module and a path planning module. The autonomous obstacle avoidance system comprises at least one first sensor, at least one second sensor, at least one third sensor and an obstacle avoidance controller. By adopting the method, the device and the system, the travel path is planned in advance through multistage control to avoid obstacles, and emergent braking measures are adopted when obstacles cannot be avoided, so that collision is avoided.

Description

technical field [0001] The present invention relates to the field of autonomous obstacle avoidance, in particular to an autonomous obstacle avoidance method, an autonomous obstacle avoidance device and an autonomous obstacle avoidance system, in particular to an autonomous obstacle avoidance method, an autonomous obstacle avoidance device and an autonomous obstacle avoidance system applicable to the field of intelligent mobile technology. failure system. Background technique [0002] At present, the field of intelligent mobile technology (including robots, automatic driving, self-balancing vehicles, etc.) has attracted the attention of professionals in the field of intelligent control and mobile devices. By combining the intelligent control technology with the mobile device, the autonomous mobile function of the mobile device can be realized, thus liberating people from the traditional control and driving work. New mobile carriers with intelligent control bring greater conv...
