Vehicle driving assistance apparatus and vehicle driving assistance method
First Claim
1. A vehicle driving assistance apparatus comprising:
- a vehicle position detector configured to detect a vehicle position of a vehicle;
a road condition predictor configured to predict a road condition at a position in front of the vehicle position detected by the vehicle position detector;
an automatic driving continuation determiner configured to determine whether or not vehicle automatic driving can be continued at the position in front of the vehicle based on the road condition predicted by the road condition predictor;
an automatic driving cancellation warner configured to warn of vehicle automatic driving cancellation when the automatic driving continuation determiner determines that the vehicle automatic driving cannot be continued at the position in front of the vehicle; and
an automatic driving canceller configured to automatically cancel the vehicle automatic driving before the position in front of the vehicle at a first distance larger than a first predetermined fixed value, when it is determined that the vehicle automatic driving cannot be continued at the position in front of the vehicle, after warning of the cancellation by the automatic driving cancellation warner;
wherein the automatic driving cancellation warner warns of the cancellation when a second distance to the position in front of the vehicle, when it is determined that the vehicle automatic driving cannot be continued at the position in front of the vehicle, becomes equal to or less than a second predetermined fixed value, the second predetermined fixed value being larger than the first predetermined fixed value; and
wherein, when the automatic driving continuation determiner determines that the position in front of the vehicle corresponds to a tunnel exit and the vehicle automatic driving cannot be continued at the tunnel exit due to a weather-induced road condition change, the automatic driving cancellation warner warns of the cancellation with an indication that the automatic driving will be canceled before the tunnel exit.

Abstract
An in-vehicle system includes a vehicle position detection unit and a vehicle position calculation unit that detect a vehicle position, a road condition prediction unit that predicts a road condition at a position in front of the detected vehicle position, an automatic driving continuation determination unit that determines whether or not the vehicle automatic driving can be continued at the position in front of the vehicle based on the road condition predicted by the road condition prediction unit, and an automatic driving cancellation warning unit that warns of cancellation of the vehicle automatic driving when the automatic driving continuation determination unit determines that it is difficult to continue the vehicle automatic driving.

10. A vehicle driving assistance method comprising:
-
predicting, by a road condition predictor, a road condition at a position in front of a vehicle position detected by a vehicle position detector, in relation to a vehicle; determining, by an automatic driving continuation determiner, whether or not vehicle automatic driving can be continued at the position in front based on the road condition predicted by the road condition predictor; warning, by an automatic driving cancellation warner, cancellation of the vehicle automatic driving when the automatic driving continuation determiner determines that the vehicle automatic driving cannot be continued at the position in front of the vehicle, and cancelling, automatically by an automatic driving canceller, the vehicle automatic driving at a point before the position in front of the vehicle at a first distance larger than a first predetermined fixed value, when it is determined that the vehicle automatic driving cannot be continued at the position in front of the vehicle, after warning of the cancellation by the automatic driving cancellation warner; wherein the automatic driving cancellation warner warns of the cancellation when second distance to the position in front of the vehicle, when it is determined that the vehicle automatic driving cannot be continued at the position in front of the vehicle, becomes equal to or less than a second predetermined fixed value, the second predetermined fixed value being larger than the first predetermined fixed value; and wherein, when the automatic driving continuation determiner determines that the position in front of the vehicle corresponds to a tunnel exit and the vehicle automatic driving cannot be continued at the tunnel exit due to a weather-induced road condition change, the automatic driving cancellation warner warns of the cancellation with an indication that the automatic driving will be canceled before the tunnel exit. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A vehicle driving assistance apparatus comprising:
-
a vehicle position detector configured to detect a vehicle position of a vehicle; a road condition predictor configured to predict a weather-induced road condition change at a position of a tunnel exit in front of the vehicle position detected by the vehicle position detector; an automatic driving continuation determiner configured to determine whether or not vehicle automatic driving can be continued at the position of the tunnel exit in front of the vehicle based on the weather-induced road condition change predicted by the road condition predictor; an automatic driving cancellation warner configured to issue a warning indicating the tunnel exit and that the vehicle automatic driving will be canceled when the automatic driving continuation determiner determines that the vehicle automatic driving cannot be continued at the position of the tunnel exit in front of the vehicle and when a distance from the vehicle position to the position of the tunnel exit becomes equal to or less than a fixed predetermined warning distance; and an automatic driving canceller configured to automatically cancel the vehicle automatic driving at another distance larger than a fixed predetermined cancelling distance before the position of the tunnel exit, when it is determined that the vehicle automatic driving cannot be continued at the position of the tunnel exit, after issuing the warning by the automatic driving cancellation warner. - View Dependent Claims (18, 19)
