A passenger in an automated vehicle may relinquish control of the vehicle to a control computer when the control computer has determined that it may maneuver the vehicle safely to a destination. The passenger may relinquish or regain control of the vehicle by applying different degrees of pressure, for example, on a steering wheel of the vehicle. The control computer may convey status information to a passenger in a variety of ways including by illuminating elements of the vehicle. The color and location of the illumination may indicate the status of the control computer, for example, whether the control computer has been armed, is ready to take control of the vehicle, or is currently controlling the vehicle.

The illustrative embodiments provide a method and apparatus for controlling movement of a vehicle. User input selecting a path for the vehicle is received from an operator. The vehicle responds to the user input by moving along the selected path in a manner that maintains the operator on a side of the vehicle. The illustrative embodiments further provide a method and apparatus for improved machine control. The vehicle receives a power-up command, instructions to execute a planned path, and information identifying a leader. The leader is an operator. The vehicle then executes the planned path using the information identifying the leader in order to follow a path of the leader. The vehicle moves along the path in a manner that maintains the leader in a position proximate to a side of the vehicle.

The illustrative embodiments provide an apparatus for processing sensor data and controlling the movement of a vehicle. In an illustrative embodiment, an operating environment around the vehicle is identified and sensor data is selected from a set of sensors. The movement of the vehicle is controlled based on the operating environment identified. In another illustrative embodiment, a sensor system has some sensors that are more accurate in a particular environment than other sensors. A dynamic condition is identified by the sensor system and commands are sent to the steering system, the propulsion system, and the braking system to move the vehicle using the sensor data detected by the sensor system. The environment is identified using the plurality of different types of sensors on the vehicle.

A trailer backup assist system for a vehicle reversing a trailer is provided herein. The system includes a steering input device for controlling a desired curvature. A controller is in communication with the steering input device and is configured to generate steering command for the vehicle to guide the vehicle and trailer onto a straight path when a straight backup request is initiated via the steering input device.

The system is an integrated and self contained electric thruster system integral with a dynamic positioning control system for dynamic positioning of any waterborne vessel having a hull with at least two sides and a deck connecting the sides, at least two azimuthing thrusters, each removably mounted to the vessel, at least two self-contained electric power units removably secured to the deck, one for each thruster, at least one dynamic positioning computer connected to each of the self contained electric power units, at least one motion reference sensor connected to the dynamic positioning computer to correct reference position signals for motion of the vessel, at least one heading sensor, and at least one sensor that is either a position reference sensor connected to the dynamic positioning computer, environmental sensors connected to the dynamic positioning computer, or a combination thereof.

A system for configuring a trailer model for a trailer maneuvering system is disclosed. The system comprises a controller having a memory and being operable to communicate with the trailer maneuvering system. The controller is configured to receive trailer dimensional data from a mobile device. The trailer dimensional data may then be stored in the memory as a first trailer profile. The controller is operable to access the trailer dimensional data in the first trailer profile to determine at least one vehicle operation configured to maneuver the trailer.

A dust detection method and apparatus of a cleaning robot. The dust detection method involves acquiring a floor image as a current floor image of a predetermined place at a current location of the cleaning robot in the predetermined place; obtaining a difference image between the current floor image and a background image selected from a feature map consisting of a plurality of floor images of the predetermined place; and detecting a dusty area based on the difference image and adjusting a cleaning power of the cleaning robot.

A vehicle-trailer back-up control system that employs an active front steer sub-system. The system includes a smart hitch controller that receives a vehicle speed signal and a hand-wheel angle signal, and calculates a hitch angle command signal. The system further includes a hitch angle sensor that measures the hitch angle between the vehicle and the trailer that is compared to the hitch angle command signal to generate a hitch angle error signal. A PID control unit receives the hitch angle error signal, and generates a corrected road wheel angle signal based on proportional and derivative gains. The corrected road wheel angle signal is used to generate a motor angle signal that is applied to a steering actuator to be combined with the steering angle signal to generate the front wheel steering signal during a back-up maneuver.

A system for calibrating a backup assist system for a trailer attached to a vehicle is provided which includes a hitch sensor continuously measuring a hitch angle for determining an angle rate, a yaw sensor continuously sensing a yaw rate of the vehicle, and a controller configured to determine an offset of the measured hitch angle when vehicle is driving forward and / or rearward.

A marine vessel running controlling apparatus controls running of a marine vessel and includes a pair of propulsion systems which respectively generate propulsive forces on a rear port side and a rear starboard side of a hull, and a pair of steering mechanisms which respectively change steering angles defined by directions of the propulsive forces with respect to the hull. The apparatus includes a target combined propulsive force acquiring section, a target movement angle acquiring section, a steering controlling section which controls the steering angles of the respective steering mechanisms such that a turning angular speed of the hull is substantially equal to a predetermined target angular speed, a target propulsive force calculating section which calculates target propulsive forces to be generated from the respective propulsion systems based on the target combined propulsive force, the target movement angle and the steering angles of the respective steering mechanisms, and a propulsive force controlling section which controls the respective propulsion systems so as to attain the target propulsive forces.
