    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, system and access station for passage control of mine vehicles. Mine vehicles (2) are transferred between an operation area (4) and a manual area (10) through one or more access stations (8). The passage station (8) comprises two successive access gates (9, 11), between which there is an intermediate space (12), to which the mine vehicle (2) to be transferred can be driven. When the mine vehicle (2) is in the intermediate space (12), at least one access gate is closed.

    Abstract: A computer-based system (100) for precisely determining an operating point for a land-based vehicle includes a receiver (216) mounted on the vehicle for receiving navigation signals from a satellite-based positioning system (218), an odometer (230) for measuring distance travelled by the vehicle, a doppler radar (232) for measuring ground speed of the vehicle, a solid-state rate sensing device (234) for measuring the heading rate of the vehicle, and a resolver (236) for measuring the steering angle of the vehicle. An extended Kalman filter (208) combines the measurements of these sensors (216, 230, 232, 234, 236) to produce a highly accurate estimate of the vehicle's operating point. The operating point includes an estimated north position, an estimated east position, an estimated heading, an estimated heading rate, and an estimated speed.
