摘要： A pump-less buoyancy engine for an autonomous underwater vehicle (AUV) includes a buoyancy reduction structure without a hydraulic pump for reducing the buoyancy of the AUV to cause the AUV to descend in the water; and a weight dropping structure for dropping prepackaged weights out of the AUV to cause the AUV to ascend in the water, where the AUV moves forward when descending and ascending.

摘要： A device for lateral guidance assistance for a vehicle includes a programmable electronic control unit and a plurality of distance sensors configured to capture obstacles to a side of and/or behind the vehicle within one or more defined warning regions. The device also includes an optical sensor device configured to capture a lane width of a current lane and/or a lane width of a neighboring lane. The programmable electronic control unit is configured such that at least one of the defined warning regions is defined in a temporally and/or spatially variable manner based on the lane width of the current lane and/or the neighboring lane.

摘要： Systems and methods for vehicle controllers for agricultural and industrial applications are described. For example, a method includes accessing a map data structure storing a map representing locations of physical objects in a geographic area; accessing current point cloud data captured using a distance sensor connected to a vehicle; detecting a crop row based on the current point cloud data; matching the detected crop row with a crop row represented in the map; determining an estimate of a current location of the vehicle based on a current position in relation to the detected crop row; and controlling one or more actuators to cause the vehicle to move from the current location of the vehicle to a target location.

摘要： A traction control system for a pallet truck includes a traction motor, an operator controlled input device configured to selectively accelerate the pallet truck in both a forward direction of vehicle travel and a reverse direction of vehicle travel, and an operator controlled actuation device configured to place the pallet truck in an auxiliary mode of operation. A vehicle controller may monitor a speed of the pallet truck and, in response to receiving an actuation signal, command the traction motor to maintain the speed of the pallet truck at an intermediate rate of travel without actuation of the operator controlled input device.

摘要： A system controls steering of a motor vehicle in case of an imminent collision with an obstacle. The vehicle includes a system to locate the vehicle relative to its lane and to determine a lateral deviation from the lane center, a determination unit for determining the presence of obstacles, a gyrometer for measuring the rotation speed of the vehicle, and a steering device, the steering angle of which can be controlled based on the measurement of a steering angle sensor or the steering torque of which can be controlled. The control system includes a perception device for determining the maximum lateral distance available for movement of the vehicle relative to obstacles, a decision device for transmitting a correction request based on the trajectory of the vehicle and on the lateral maximum distance, and an intervention device for controlling the steering device to correct the trajectory of the vehicle.

摘要： Disclosed are an improved nozzle for an unmanned underwater vehicle (UUV), and a method for operating the same. The nozzle includes a first rigid member operatively coupled to a UUV steering mechanism. The nozzle also has a second rigid member, coupled to the first rigid member by a flexible bellows according to a configurable operating angle. The nozzle does not extend beyond a bounding surface when stored but does when deployed. Water traversing the first rigid member and contacting the second rigid member produces a reactive force according to the configurable operating angle. Simultaneous and independent control of the volume of fluid traversing several such nozzles in the UUV, and their respective orientations and operating angles, permits automatic station-keeping or navigation according to another guidance objective.

摘要： A lane change controller determines whether lane change is available or unavailable on the basis of a detection result of an obstacle by a radar and an obstacle recognizer in response to detection of a winker operation by an operation detection unit. A lane keep controller continues lane keep control if the operation detection unit detects the winker operation during the lane keep control and if the lane change controller determines that the lane change is unavailable.
