A work vehicle periphery monitoring system includes: an alarm range storage unit that stores an alarm range, in which an alarm output is required when an object is present, in a detection range of an object detection device that detects an object present in a periphery of a work vehicle; a work mode determination unit that determines a work mode of the work vehicle; an alarm range changing unit that changes the alarm range in the detection range when it is determined that the work mode is a specific work mode; and an alarm control unit that causes an alarm device to output an alarm when an object is present in the alarm range.

The techniques and systems herein enable target-velocity estimation using position variance. Specifically, a plurality of detections of a target are received for respective times as the target moves relative to a host vehicle. Based on the detections, two-dimensional positions of the target relative to the host vehicle are determined for the respective times. Based on the positions of the target at the respective times, a first variance is determined for a first dimension of the positions, and a second variance is determined for a second dimension of the positions. Based on the first and second variances, an estimated velocity of the target is calculated. By basing the estimated velocity on the variances of the positions, more-accurate estimated velocities may be generated sooner, thus enabling better performance of downstream operations.

This application provides example detection signal transmitting methods, detection apparatuses, and storage medium. One example method includes determining an orientation of a field of view of a detection apparatus. One of a plurality of anti-interference parameters can then be selected as a target anti-interference parameter based on the orientation of the field of view of the detection apparatus and according to a predefined rule, where the plurality of anti-interference parameters are determined according to the predefined rule. A detection signal can then be transmitted based on the target anti-interference parameter.

A system for a vehicle includes a rear gate assembly of the vehicle that includes a closure panel operable to pivot vehicle-downward from a closed position to an open position. The system also includes a support feature coupled to the closure panel and operable to move relative to the closure panel between a retracted position and a deployed position. In the open position of the closure panel, the position of the support feature in the deployed position is further vehicle-downward than the position of the support feature in the retracted position. The system also includes a sensing system of the vehicle that detects a living being proximate to the rear gate assembly. The system further includes a controller that authenticates an identity and determines a position of the living being based on data received from the sensing system and prompts movement of the support feature from the retracted position to the deployed position based on the authenticated identity and determined position of the living being.

Systems, methods and circuitries are disclosed for compressing radar data.

A vehicle includes a communicator that is mounted on the vehicle to perform wireless communication with a server and a controller operates the communicator to transmit an accident reception request signal and image data acquired by another vehicle to the server when the vehicle has an accident with an accident target vehicle. The controller operates the communicator to receive a fault ratio from the server when the server generates fault ratio data between the vehicle and the accident target vehicle based on the image data.
