Driving route generation device

摘要

A selection track setting section in a driving route generation device determines as a selected track a track of a preceding vehicle when a detection section and a track generation section detects a track of the preceding vehicle which is running on the same driving lane of a host vehicle. A candidate track selection section outputs as a candidate track one of tracks of front vehicles, detected by the detection section and the track generation section, other than the track of the preceding vehicle. A switching selection section switches as the selected track from the track of the preceding vehicle to the candidate track when a detection of the track of the preceding vehicle is interrupted during a predetermined detection period. An estimate route generation section generates an estimated driving route of the host vehicle on the bass of the selected track.

主权项

1. A driving route generation device comprises:
a track detection section configured to detect a track of each of a plurality of vehicles which are running in front of a host vehicle; a selection section configured to select one of the tracks detected by the track detection section and output the selected track, the selection section comprising:
a preceding vehicle track selection section configured to select, as the selected track, the track of the preceding vehicle when the track of the preceding vehicle, which is running on a same driving lane of the host vehicle, is detected by the track detection section;a candidate track selection section configured to select, as a candidate track, one of the tracks of the front vehicles other than the track of the preceding vehicle; anda selection track switching section configured to switch, as the selected track, from the track of the preceding vehicle to the candidate track when a detection of the track of the preceding vehicle is interrupted for a predetermined detection period, and an estimated driving route generation section configured to generate an estimated driving route of the host vehicle on the basis of the selected track selected by the selection section, wherein the host vehicle performs automatic steering to run on the estimated driving route; wherein when there are a plurality of the front vehicles, the selection track switching section in the selection section selects, as the candidate track, one of the tracks of the front vehicles which is closest to the track of the preceding vehicle.
