摘要： An object of the invention of the application is to provide an autonomous travelling mine vehicle that can suppress a decrease in work efficiency when dust is generated at a work site. Therefore, the autonomous travelling mine vehicle includes a surrounding monitoring sensor that measures a three-dimensional point cloud of a terrain profile around the vehicle body, and a travelling route setting device calculates an undetected area representing a terrain profile part that the surrounding monitoring sensor cannot measure, calculates an alternative route on which the vehicle body can travel without passing through the undetected area on the basis of the positional relationship between the undetected area and the vehicle body, and updates the scheduled route with the alternative route.

摘要： The present disclosure provides a work vehicle that allows detecting an error in an installation position of an antenna more flexibly than a conventional device. The work vehicle includes a control device 150. The control device 150 has a detection function F106, a calculation function F104, a calculation function F105, a calculation function F107, and an estimation function F110. The detection function F106 detects steady traveling based on a velocity, an acceleration, and an angular velocity of a vehicle. The calculation function F104 calculates a first vehicle direction based on installation information of a first antenna and a second antenna with respect to the vehicle. The calculation function F105 calculates a second vehicle direction based on a time change of position information of the first antenna when the steady traveling is detected. The calculation function F107 calculates a direction correction parameter for correcting the first vehicle direction based on the second vehicle direction. The estimation function F110 estimates a location and a posture of the vehicle based on the direction correction parameter and the first vehicle direction.

摘要： Provided is a control system for hauling vehicle capable of suppressing slippage of a hauling vehicle while suppressing a decrease in travel speed of the hauling vehicle. A control system for hauling vehicle causes a hauling vehicle 100 to travel based on a control target including a target route. The control system generates a control target based on the map information, which includes information on the travel path WP along which the hauling vehicle 100 travels and information on a plurality of travel sections TS obtained by dividing the travel path WP; the loading quantity on the hauling vehicle 100 in each travel section TS; and a slippage index indicating the slipperiness of the travel path WP in each travel section TS. If the slippage index SI of at least one travel section TS is less than the predetermined threshold, the control system sets a larger turning radius of the turning route included in the target route for that travel section TS than for the case where the slippage index is equal to or greater than the predetermined threshold.

摘要： An off-road dump truck includes a vehicle body, a peripheral recognition device, and an obstacle discrimination device. The peripheral recognition device detects obstacle candidates in front of the vehicle body. The obstacle discrimination device classifies the obstacle candidates, which were detected by the peripheral recognition device, into obstacles and non-obstacles and outputs, as obstacles, the obstacle candidates classified as obstacles. The obstacle discrimination device includes a travel state determination section, a distance filter section, and a reflection intensity filter section. The travel state determination section determines whether each obstacle candidate is a moving object or a stationary object. The distance filter section compares a distance, where the stationary object was first detected, with a distance threshold. The reflection intensity filter section calculates statistical information based on reflection intensity information on the obstacle candidate, and based on a comparison result of the statistical information with a threshold, classifies the obstacle candidate.

摘要： A mining work machine includes an obstacle determination device connected to a periphery detection device. If measurement points detected by the periphery detection device in a current cycle are equal to or greater than predetermined size thresholds equivalent in size to the mining work machine, these measurement points are put into a single obstacle candidate group. Based on relative speeds of the obstacle candidate at the measurement points and a traveling speed of the mining work machine, it is determined whether the obstacle candidate is a stationary object or a moving object, and whether the stationary object has been also detected by the periphery detection device in a preceding cycle. If a position of detection of the stationary object detected for the first time is equal to or smaller than a non-obstacle determination distance threshold, the obstacle determination device outputs the obstacle candidate as a non-obstacle.
