Abstract:
A method and mine vehicle includes at least one scanning device for scanning surroundings of the mine vehicle and producing operational point cloud data. The mine vehicle has a control unit provided with reference point cloud data of the mine. The control unit is configured to match the operational point cloud data to the reference point cloud data in order to determine position of the mine vehicle. The control unit further includes a mine work plan, which is connected to the detected position of the mine vehicle.
Abstract:
The present invention relates to a method for providing and acquiring information along a vehicle's itinerary. The method comprises the step of using sensor means to scan (S1) information provided by at least one information means. The method further comprises the steps of using the sensor means to activate (S2) said information means by illumination and using the sensor means to extract (S3) information thus activated from said information means as a basis for the operation of the vehicle, said information means having at least one reflecting surface which is scanned by said sensor means. The present invention relates to a system for providing and acquiring information along a vehicle's itinerary, and a motor vehicle provided with such a system. The present invention relates also to a computer programme and a computer programme product.

Abstract:
The present invention relates to a method for driving a mining and/or construction machine, where said machine is arranged to be controlled by an operator by means of maneuvering means, where said operator, when driving said machine, provides steering commands by means of said maneuvering means for maneuvering said machine. The method comprises, when said machine is being driven in an environment having at least a first obstacle—estimating a path that, has been requested by said operator by means of said steering commands,—by means of a control system determining whether said machine when moving according to said requested path will be driven within a first distance from said first obstacle, and—when said machine, when travelling along said path, will be driven within a first distance from said first obstacle, influencing the path of said machine by means of said control system.

Abstract:
The present invention provides a guidance, navigation, and control method and system for an underground mining vehicle that allow said vehicle to be taught a route by a human operator and then have it automatically drive the route with no human intervention. The method works in three steps: teaching, route profiling, and playback. In the teaching step the vehicle is manually driven by a operator (or using tele-operation whereby the operator views a screen displaying live views from vehicle-mounted cameras and using remote controls) along a route which can consist of an arbitrary sequence of maneuvers including tramming forwards, switching directions, tramming backwards, turning, or pausing movement. During this phase raw data from vehicle-mounted sensors including odometric sensors and rangefinders are logged to a file throughout teaching for later processing. During the (offline) route profiling step, the raw data in the log file are processed into a route profile including a vehicle path, a sequence of local metric submaps located along the path, and a profile of desired speed as a function of distance along the path. During the playback step, the vehicle automatically repeats the route that was taught during the teaching phase, as represented by the route profile. This is accomplished by first determining where the vehicle is on the route using a localization method which uses the odometric and laser rangefinder sensors and the local metric maps to determine the vehicle location. A steering control method adjusts the vehicle's steering to ensure it tracks the intended path. A drive control method adjusts the vehicle's speed accordingly and safety method ensures the vehicle stops in the event that an obstruction is on the vehicle's intended path.
Abstract:
The invention relates to a method of driving mine vehicles in a mine, and to a transport system. A plurality of mine vehicles (1a to 1d) is arranged in succession and driven in convoy (13) between working areas (18a, 18b). A master vehicle (1a) in the convoy is driven manually, and slave vehicles (1b to 1d) follow the master, provided with no mechanical connection. In the working areas, the convoy is disassembled, since single vehicles are each driven separately. When assigned tasks in the working areas have been completed, the vehicles are reassembled into a convoy so as to be driven to a next working area.
