Automatic driving mining dump truck environment sensing system and mining dump truck

Abstract

The invention discloses an automatic-driving mining dump truck environment sensing system and a mining dump truck, and the system comprises a vehicle-mounted calculation unit which receives the data of the environment sensing system, carries out the extraction and processing of the data, and transmits a processing result to a central control unit of a vehicle; the environment sensing system comprises a laser radar, a millimeter-wave radar, an image sensor and integrated navigation equipment, wherein the laser radar is used for detecting target information right ahead and right behind a vehicle, the millimeter-wave radar is used for detecting target information in front of and on two sides of the vehicle, the image sensor is used for detecting target information around the vehicle, and theintegrated navigation equipment is provided with a GPS antenna for acquiring the position information of the vehicle in real time. According to the invention, tnvironment information is obtained through the millimeter-wave radar and the image sensor and fused with laser radar data, the phenomenon that the precision of the radar is insufficient can be overcome, the automatic driving safety is improved, and the cost is reduced as much as possible while normal work and vehicle safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic driving of mine dump trucks, in particular to an environment perception system for an automatic driving mine dump truck and the mine dump truck. Background technique [0002] Self-driving mining dump trucks, also known as unmanned mining vehicles, or unmanned mining trucks for short, are mainly intelligent mining dump trucks that realize automatic driving technology through on-board computing units. As an essential technical support for autonomous driving, on-board sensors are the most important carrier it relies on, so the sensor layout is the key link of autonomous driving cars. The premise that the mining dump truck can drive stably is mainly through the perception of the surrounding environment information of the mining dump truck. In detail, the unmanned mining truck mainly relies on components such as lidar, millimeter wave radar, and on-board image sensor to obtain the surrounding enviro...
