Abstract: A metric priority is accessed, which identifies a priority of a plurality of different control metrics that are used in controlling an agricultural implement. Control signals are generated to control the implement to bring the metrics within corresponding predefined ranges in descending order of priority.

Abstract: An inertia-based navigation apparatus and an inertia-based navigation method based on relative preintegration are provided. The inertia-based navigation apparatus includes: a first sensor detecting and outputting motion information about a moving body which is moving, based on a first coordinate system; a second sensor detecting and outputting inertia data about a translational acceleration and a rotational angular velocity related to the movement of the moving body, based on a second coordinate system; and a controller determining, at every first time, pose information about a position, a velocity and an attitude of the moving body in a reference coordinate system, based on the motion information and the inertia data.
Abstract: A drone system has a camera mounted to a frame of a drone, the camera configured to acquire image data upon receipt of a signal from a flight controller and a precision location device configured for continuously obtaining location data. Additionally, the drone system has a computing device configured for receiving a signal indicating that an image has been acquired, the computing device configured for transmitting a signal to a precision location device indicating that an image has been acquired, and the precision location device is further configured to record event data associated with a time indicating when the image was acquired.

Abstract: At a time when it is possible for a user's own vehicle to pull out from a parking space, an assist control unit of a parking exit assist device terminates an assist control in the event that the user's own vehicle has traveled forward by a predetermined distance (a minimum forward distance) from a predetermined position (a most recent intermediate position or an assist starting position).

Abstract: A driving control method may include performing a road surface adaptability control in which when an uneven road surface of a road on which a vehicle is driven is recognized by a controller, a wheel torque control of the vehicle is performed so that a squat effect and a dive effect are generated in the vehicle passing through the uneven road surface.

Abstract: A vehicle control apparatus includes a deviation detector and a motor controller. The deviation detector is configured to detect a deviation of a host vehicle from a travel lane. Upon the deviation detector detecting the deviation, the motor controller is configured to increase and decrease torque of a driving motor that transfers a driving force to a wheel.
Abstract: Provided is a steering controller configured to switch from an interruption state to a transmission state. In a state where power transmission from the steering wheel to steered wheels is interrupted, a maximum value selection processing circuit outputs a maximum value, out of a steered angle and a steering angle, to a limiting reaction force setting processing circuit. When the absolute value of the maximum value has become equal to or larger than a limitation start threshold value, the limiting reaction force setting processing circuit rapidly increases a limiting reaction force. An operation signal generation processing circuit controls a reaction-force motor to achieve a reaction force command value corresponding to the limiting reaction force. When the absolute value of the maximum value has become equal to or larger than an engagement threshold value, a clutch is engaged to transmit reaction force from the steered wheel-side to the steering wheel.
Abstract: A vehicle seat is provided with a side support device configured to assist vehicle exit behavior of an occupant while stably securing a holding property for the sitting occupant. The vehicle seat includes a side support device configured to support a cushion side portion of a seat cushion to be switchable between a seating available position and a vehicle exit assist position, a lock device configured to lock the cushion side portion in the seating available position, and a lock release device configured to release a lock state of the lock device. The lock release device includes a first lever configured to detect sitting of the occupant on a cushion center portion and a second lever configured to detect sitting of the occupant on the cushion side portion. The lock state is released when the detection by the second lever occurs while the detection by the first lever continues.
Abstract: Improved processing of sensor data (e.g., LiDAR data) can be used to distinguish between free space and objects/hazards. Autonomous vehicles can use such information for performing autonomous driving and/or parking operations. LiDAR data can include a plurality of range measurements (e.g., forming a 3D point cloud). Each of the range measurements can correspond to a respective LiDAR channel and azimuth angle. The processing of LiDAR data can include identifying one or more paths as candidate ground paths based on one or more path criteria. The processing of LiDAR data can also include identifying one or more of the plurality of range measurements as ground points or non-ground points based on the one or more paths identified as candidate ground paths and based on one or more point criteria.

Abstract: A steering control device includes a command value setting processing portion configured to set a current command value based on a detection value of steering torque; a feedback processing portion configured to control a voltage applied to a motor so as to control a current flowing through the motor to the current command value, based on an output value of an integral element obtained by using a difference between the current and the current command value; an end determination processing portion configured to determine whether a turning angle of steered wheels has reached a limit angle; and an end-time limit processing portion configured to perform correction to increase a magnitude of the difference, based on a degree of a decrease in a magnitude of a rotational speed of the motor when the end determination processing portion determines that the turning angle has reached the limit angle.

Abstract: A tailgating detection and monitoring assembly includes a speed detector, a sensor, a visual warning module, and an imager, which are configured to couple to a rear window of a first vehicle and are operationally coupled to a control module. The speed detector is configured to measure a speed of the first vehicle. The sensor is configured to measure a distance between the first vehicle and a second vehicle that is behind the first vehicle. The control module is positioned to determine a separation between the first vehicle and the second vehicle and a speed of the second vehicle based on signals from the speed detector and the sensor to determine a tailgating event. The control module is positioned to command the visual warning module to display a notification to a driver of the second vehicle and to command the imager to capture an image of the tailgating event.
