Spatial and temporal processing of ultrasonic sensor detections for mapping in vehicle-parking-assist functions

摘要

This document describes spatial and temporal processing of ultrasonic-sensor detections for mapping in vehicle-parking-assist functions. Specifically, spatial intersections, which are determined from a pair of neighboring ultrasonic sensors having ultrasonic detections at substantially the same time, can address latency issues associated with temporal intersections and can be determined without the vehicle moving. Temporal intersections can address situations when one sensor of the pair of neighboring ultrasonic sensors has an ultrasonic detection while the other sensor does not. Using both the spatial and temporal intersections provides high accuracy for angular information, which enables enhanced mapping and efficient performance of vehicle-parking-assist functions.
