A robotic system and method for aligning a target to an equipped vehicle for calibration of a sensor on the equipped vehicle includes a vehicle support stand upon which an equipped vehicle is disposed in an established known position for calibration of the sensor, and a robotic manipulator having a multi-axis robotic arm configured to moveably hold a target. The robotic manipulator is configured to position the target into a calibration position relative to the sensor on the equipped vehicle by longitudinal movement of the robotic manipulator relative to the vehicle support stand and by movement of the robotic arm based on the established known position of the equipped vehicle on the vehicle support stand whereby the sensor is able to be calibrated using the target.

An ultrasound flow measurement device has a vessel through which a fluid to be measured flows. An ultrasound measurement configuration with an ultrasound transducer is provided for measuring a propagation time of an ultrasound signal containing a plurality of periods along a measurement section that runs partly in a direction of flow. A controller determines a fluid flow on a basis of a propagation time measurement. The controller contains a memory, a first evaluator for determining a period duration of at least one of the periods of an ultrasound signal received after passing through the measurement section, a second evaluator for determining a spread value of a predetermined number of last received ultrasound signals, a comparator for comparing the spread value with a threshold value, and an actioning device for initiating a control action, assigned to the threshold value that has been exceeded, for the ultrasound flow measurement device.

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.

A vehicle analysis environment includes one or more display screens, such as a display screen wall or an array of display screens. While a vehicle is in the vehicle analysis environment, a vehicle analysis system renders and displays one or more vehicle sensor calibration targets and/or one or more simulated events on the one or more display screens. Vehicle sensors of the vehicle capture sensor data while in the vehicle analysis environment. The sensor data depict the vehicle sensor calibration targets and/or the simulated events that are displayed on the one or more display screens. The vehicle can output actions based on the simulated event and/or can calibrate its vehicle sensors based on the vehicle sensor calibration targets.

In various embodiments, methods, systems, and vehicle apparatuses are provided. A method for estimating a Hitch Articulation Angle (HAA) using Ultra-Sonic Sensors (USSs) while ensuring quality detected echo signal performance using plausibility filtering, generating at least one set of USS data based on detecting a set of echo signals generated by a plurality of USSs configured about a vehicle coupled to a trailer; determining based on a set of USS data using a selected set of geometric equations in a plausibility filtering process for an arbitrary frontal shape of the trailer; and generating at least one comparison based on at least one set of USS data estimations to a kinematic model at low speeds for ensuring that results of the kinematic model to the HAA associated with the determined trailer shape is based on a pair of detected echo signals that are deemed to have a higher signal performance.
