Title:
PATH ESTIMATING DEVICE, AND PATH ESTIMATING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/013105
Kind Code:
A1
Abstract:
The suitability of the results of estimating the travel route of a host vehicle is self-diagnosed without using GPS, etc. A path estimating device comprising: a path estimating unit that calculates parameters on the basis of steering angle and a vehicle speed sensor to estimate a host vehicle path; a sensor that detects the actual value of a parameter or the actual value of a value for calculating the parameter; a parameter recording unit that stores parameters estimated by the path estimating unit, and the actual value of the parameter detected by the sensor or the actual value of the value for calculating the parameter; a correlation calculating unit for finding a correlation between the actual value of the parameter detected by the sensor at a first time or the actual value of the value for calculating the parameter stored in the parameter recording unit, and a parameter at the first time in the host vehicle path estimated at a second time before the first time by the path estimating unit; and an abnormality determining unit that determines whether the correlation is within a predetermined distribution range, and when not within the distribution range, determines the estimation of the host vehicle path to be abnormal.
