Abstract

The invention belongs to the technical field of electrical structure connection, and particularly relates to a low-cost pilotless automobile obstacle-avoidance device which comprises a laser range finder, a corner steering engine, a controller, a GPS and a direction steering engine. According to the device, the advantages and the defects of the prior art are used for reference, the laser range finder capable of deflecting is installed in front of the vehicle, the obstacle distance in a fan-shaped area in front of the vehicle is rapidly scanned, the vehicle is controlled to enter an obstacle avoidance mode, the purpose of autonomous obstacle avoidance and detour is achieved, the cost is greatly reduced, and the safety of the pilotless automobile is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical structure connection, and in particular relates to a low-cost unmanned vehicle obstacle avoidance device. Background technique [0002] In recent years, with the development of automation, unmanned vehicles have very broad prospects for development, especially in the military field. After simple modification, unmanned vehicles can be downgraded and used as moving target vehicles in the field of missile testing. In order to improve the safety of human-driven cars, more and more users have proposed that the moving target car should have the function of autonomous obstacle avoidance. Referring to relevant research, it is found that the signal sources currently used for autonomous obstacle avoidance of driverless vehicles mainly include the following methods: [0003] 1. LiDAR test obstacles. Install a 360° laser radar on the top of the controlled vehicle to obtain the location information of obst...
