Abstract: Methods and systems are disclosed for radio positioning of a vehicle using a virtual positioning reference established by logging a known position of the vehicle together with a local time that a first instance of a predictably repeated code word is received from an opportunistic terrestrial radio transmitter. During movement of the vehicle to a second, unknown position, a local clock is used to determine the time difference between when the virtual positioning reference is predicted to receive a second instance of the code word and when the vehicle actually receives the second instance of the code word, thereby providing positioning information when traditional navigation signals such as GPS are not available. The radio positioning information is then used to initiate an action such as recording the location information for future retrieval by a user, and/or controlling the movements of an autonomous vehicle.

Abstract: A preceding vehicle selection apparatus estimates a curvature of a road on which an own vehicle is traveling, detects an object ahead of the own vehicle, and determines a relative position in relation to the own vehicle. Based on the curvature and the relative position, an own vehicle lane probability instantaneous value is determined. This instantaneous value is a probability of the object ahead being present in the same vehicle lane as the own vehicle. By a filter calculation on the instantaneous value, an own vehicle lane probability is determined. Based on the own vehicle lane probability, a preceding vehicle is selected. An inter-vehicle time required for the own vehicle to reach a detection position of the object ahead is calculated. Based on the inter-vehicle time, characteristics of the filter calculation are changed such that an effect of the own vehicle lane instantaneous value increases as the inter-vehicle time decreases.

Abstract: A preceding vehicle selection apparatus estimates a curvature of a traveling road on which an own vehicle is traveling, detects an object ahead of the own vehicle, and determines a relative position in relation to the own vehicle, for each object ahead. Based on the estimated curvature and the determined relative position, an own vehicle lane probability instantaneous value for each object ahead is repeatedly determined. An own vehicle lane probability is determined by performing a filter calculation on the calculated own vehicle lane probability instantaneous value. Based on the determined own vehicle lane probability, a preceding vehicle is selected. Characteristics of the filter calculation are set such that an object ahead associated with a preceding vehicle selected in a previous processing cycle is relatively less affected by the own vehicle lane probability instantaneous value than an object ahead associated with an object other than the preceding vehicle.

Abstract: A system and method for various levels of automation of a swing-to-hopper motion for a rope shovel. An operator controls a rope shovel during a dig operation to load a dipper with materials. A controller receives position data, either via operator input or sensor data, for the dipper and a hopper where the materials are to be dumped. The controller then calculates an ideal path for the dipper to travel to be positioned above the hopper to dump the contents of the dipper. In some embodiments, the controller outputs operator feedback to assist the operator in traveling along the ideal path to the hopper. In some embodiments, the controller restricts the dipper motion such that the operator is not able to deviate beyond certain limits of the ideal path. In some embodiments, the controller automatically controls the movement of the dipper to reach the hopper.
