Abstract
A vehicle travel control apparatus includes an anomaly monitoring section for determining, through monitoring, whether or not a driver is in an anomalous state in which the driver has lost his or her ability to drive the vehicle, and a deceleration section for automatically stopping the vehicle by decelerating the vehicle after a final anomaly determined time which is a point in time when the anomaly monitoring section finally determines that the driver is in the anomalous state. The deceleration section prohibits deceleration of the vehicle in the case where the deceleration section determines that the vehicle is present in the deceleration prohibited section after the final anomaly determination time.
Claims13
A vehicle travel control apparatus applied to a vehicle, comprising:
- at least one electronic control unit configured to:
- determine, through monitoring, whether or not a driver of the vehicle is in an anomalous state in which the driver has lost his or her ability to drive the vehicle;
- automatically stop the vehicle by decelerating the vehicle after a final anomaly determined time which is a point in time when it is determined that the driver is in the anomalous state;
- determine whether or not the vehicle is present in a deceleration prohibited section, determined on the basis of places where automatically stopping the vehicle is inappropriate from a viewpoint of an ordinance, through use of at least either of
- division line information regarding division lines on left and right sides of a travel path of the vehicle recognized from road image data from an image capturing apparatus when the vehicle includes the image capturing apparatus, and
- road information regarding the travel path of the vehicle obtained from a navigation apparatus when the vehicle includes the navigation apparatus;
- not decelerate the vehicle in a case where it is determined that the vehicle is present in the deceleration prohibited section after the final anomaly determined time;
- start deceleration of the vehicle from a provisional anomaly determined time which is a point in time which is before the final anomaly determined time and at which it is determined that the driver is highly likely to be in the anomalous state;
- and
- not decelerate the vehicle in a case where it is determined that the vehicle is present in the deceleration prohibited section after the provisional anomaly determined time.
