The objective of the present invention is to provide a vehicle control device capable of preventing repetition of movement on the same route when a route including back and forth turning has been planned. A vehicle control device (10) according to the present disclosure comprises a route generating unit (11) for generating a first route for moving from a first location to a target location, a control unit (12) for controlling a drive unit to move along the first route, and a determining unit (13) which, if the first route includes a second route to a back and forth turning point and a third route from the back and forth turning point to the target location, determines whether, at a second location, the vehicle can be deemed to have arrived at the back and forth turning point, wherein, if it is determined that the vehicle is deemed to have reached the back and forth turning point at the second location, the control unit (12) controls the drive unit such that the vehicle proceeds to a position on the third route separated a second distance, greater than a first distance between the first location and the back and forth turning point, from the second location.

A system for localization and manipulation of infrastructure includes: a mobile robotics platform; one or more sensors configured to collect sensor data; a processor configured to process the sensor data to identify and localize the infrastructure; and a feedback device configured to confirm the system has correctly identified and localized the infrastructure. The system includes a database of infrastructure descriptors and may spatially register those descriptors to the mobile platform's environment. The mobile robotics platform may employ those infrastructure descriptors as priors to improve sensing and actuation in the identification, localization, and manipulation of infrastructure.

This disclosure relates to a hybrid power engine and battery system (100) for a drilling rig. The system includes: at least one internal combustion engine (110); an electric motor and generator assembly (120) mechanically connected to the at least one internal combustion engine (110) and electrically connected to an energy storage system (130) for charging and discharging the energy storage system; a compressor (140) mechanically connected to the at least one internal combustion engine and the electric motor and generator assembly via a clutch (150); a towing system (160) connected to the electric motor and generator assembly; and a control device (180) configured to control one or more of the electric motor and generator assembly, the compressor, the clutch, and the towing system, as well as the at least one internal combustion engine, based on the fuel efficiency of the at least one internal combustion engine.

A control system for a vehicle uses one or more inputs of a velocity request, a brake request, a speed request, travel direction indication, engine speed, and vehicle speed to determine a control strategy for a continuously variable transmission. A target engine speed is selected based upon the inputs, and the engine and continuously variable transmission ratio are controlled to achieve the target engine speed while controlling the vehicle according to the inputs. In some embodiments, the control strategy further selects the target engine speed according to accessory system demands, such as a hoist or lift system.

A materials handling vehicle comprises a drive unit, steering unit, localization module, and navigation module which are configured to cooperate to direct the materials handling vehicle along a travel path in a warehouse. A path validation tool comprises environmental layout data of the warehouse, a proposed travel path within the warehouse, kinematics of the materials handling vehicle, a dynamic exterior boundary of the materials handling vehicle, and a dynamic clearance boundary of the materials handling vehicle. The dynamic clearance boundary is enlarged relative to at least a portion of the dynamic exterior boundary of the materials handling vehicle to define an enlarged boundary about at least a portion of the materials handling vehicle. The path validation tool is configured to: execute path validation logic to determine vehicle pose along the proposed travel path; determine whether the dynamic exterior boundary or the dynamic clearance boundary of the vehicle is likely to intersect obstacles represented in the environmental layout data, based on the determined vehicle pose and a degree of potential impingement at candidate positions along the proposed travel path, to respectively identify an obstacle collision error or a pinch point error; and modify the proposed travel path to avoid or mitigate against possible collisions and pinch points, wherein avoidance of collisions is prioritized over avoidance of pinch points.

[Problem] To provide a hybrid system which can detect and store a temperature of a battery that supplies electric power to a motor at the time of storage, while power consumption of the battery that supplies the electric power to an ECU is suppressed.[Solution] A hybrid system 10 is a hybrid system mounted on an industrial machine and has a motor 2, a battery 50 that supplies electric power to the motor 2, and a storage portion 151 and also includes a control portion 150 that executes such control that detects a temperature of the battery 50, when an ignition switch of the industrial machine is turned on, and stores the temperature at the detection as a temperature of the industrial machine at the time of storage in the storage portion 151.
