TRAVEL PATH ESTIMATING DEVICE

WIPO Patent Application WO/2021/044811

A1

Provided is a travel path estimating device capable of accurately estimating a travel path of a host vehicle when the host vehicle turns right and left (also called "during turning"). The device comprises prediction processing units 116 and 216 including prediction units 111 and 211 that predict a future steering angle amount on the basis of a steering angle change rate. The device also comprises an adjustment processing unit 210 including an adjustment unit 202 that, compared to before adjustment, increases a change in estimated travel path coordinates with respect to time by adjusting a steering angle. The device further comprises a model switching unit 217 that switches between adjustment processing operations by the adjustment processing unit 210 and prediction processing operations by the prediction processing unit 216. The adjustment processing operations by the adjustment processing unit 210 including the adjustment unit 202 are used in the first half of estimation, and the prediction processing operations by the prediction processing unit 216 including the prediction unit 211 are used in the second half of the estimation.
