Title:
AIMING DEVICE, DRIVING CONTROL SYSTEM, AND METHOD FOR CALCULATING CORRECTION AMOUNT FOR SENSOR DATA
Document Type and Number:
WIPO Patent Application WO/2021/024711
Kind Code:
A1
Abstract:
The purpose of the present invention is to correct axial deviation of a sensor. This aiming device, which calculates a correction parameter for correcting a detection result from a target sensor, is provided with: an estimated path generation unit that uses information about the behavior of a host vehicle as detected by a behavior sensor to detect the path of a target while the host vehicle is moving and uses a first variable group to generate, from the detected path of the target, a plurality of estimated paths having different starting point positions; a corrected path generation unit that uses a second variable group to generate a plurality of corrected paths from the path of the target in the vicinity of the host vehicle and detected by the target sensor; and a correction parameter calculation unit that selects a combination of an estimated path and corrected path with a small difference therebetween and uses a first variable pertaining to the selected estimated path and a second variable pertaining to the selected corrected path to calculate a correction parameter for correcting displacement of the target sensor.
