A method of indicating to an operator of a work vehicle a relative location of an object, an object indication system, and a work vehicle are provided. The method includes sensing the object with one or more sensors positioned at one or more sensor positions on the work vehicle and activating one or more indicators positioned at one or more indicator positions relative to the operator based on the sensing of the object with the one or more sensors. Each sensor position directionally corresponds to one or more of the indicator positions.

A sensor attachment is used in securing an ultrasonic sensor to a plate-like vehicle body member. The ultrasonic sensor is equipped with a cylindrical ultrasonic microphone extending in an axial direction perpendicular to a center axis line. The sensor attachment includes a cylinder which is fit in a through-hole in the vehicle body member and surrounds the ultrasonic microphone in a vehicle-mounted state where the ultrasonic sensor is mounted in the vehicle body member. The cylinder includes a through-hole facing portion which faces an inner surface of the through- hole in proximity thereto in a radial direction perpendicular to the center axis line in the vehicle- mounted state. The through-hole facing portion is designed to have a contact surface-decreasing structure which minimizes an area of contact with the inner surface of the through-hole.

An ultrasonic sensor is provided with a sensor body, a cushion member, a retainer part and a waterproof seal. The sensor body has an ultrasonic microphone and a microphone support part. The cushion member covers a protrusion part of the ultrasonic microphone. The retainer part sandwiches a sandwiched part on a proximal end side between the retainer part and an outer peripheral surface of the ultrasonic microphone, while exposing an exposed part on a tip end side in the axial direction of the cushion member. The waterproof seal blocks a gap between a vehicle body component and the exposed part of the cushion member in an on-board state.

A vehicular test system for testing a vehicular sensing system includes a sensor support structure having a proximal end disposed at a vehicle, a distal end extending away from the vehicle, and a force providing element that provides a force to move the distal end of the sensor support structure. A vehicular sensor is disposed at the distal end of the sensor support structure. When the vehicular sensor is approaching a collision with an object, such as during testing of vehicular sensors and vehicular sensing systems, a control controls the force providing element to move the distal end of the sensor support structure and the vehicular sensor to avoid the collision.

This document describes near-object detection using ultrasonic sensors. Specifically, when an object is in a near-object range or distance from a vehicle, an object-detection system of the vehicle can utilize raw range measurements and various parameters derived from the raw range measurements. The various parameters may include an average, a slope, and a variation of the range. In the near-object range, using the parameters derived from the raw range measurements may lead to increases in the accuracy and performance of a vehicle-based object-detection system. The increased accuracy in near-object detection capability enhances safe driving.
