Alerting apparatus
First Claim
1. An alerting apparatus that issues an alert regarding a moving obstacle to a driver of a host vehicle, when the host vehicle enters an intersection of a crossroad that is connected to a traveling road on which the host vehicle is traveling, and the traveling road, in a left-hand traffic jurisdiction, the alerting apparatus comprising:
- an ECU configured todetermine a traveling direction of the host vehicle entering the intersection;
set an intersect determination range that extends out in front of the host vehicle from the host vehicle, based on a result of the determination;
obtain position information of the moving obstacle;
estimate a path of the moving obstacle, based on the position information of the moving obstacle;
determine whether the path of the moving obstacle intersects with the intersect determination range;
issue the alert regarding the moving obstacle to the driver when it is determined that the path of the moving obstacle intersects with the intersect determination range; and
set the intersect determination range to be shorter in length in a front-rear direction of the host vehicle when the traveling direction of the host vehicle is a left turn than when the traveling direction of the host vehicle is a right turn.

Abstract
An alerting apparatus issues an alert regarding a moving obstacle to a driver of a host vehicle when the host vehicle enters an intersection of a crossroad that is connected to a traveling road on which the host vehicle is traveling, and the traveling road, in a left-hand traffic jurisdiction. This alerting apparatus includes an ECU. The ECU is configured to issue the alert regarding the moving obstacle when it is determined that a path of the moving obstacle intersects with an intersect determination range, and set the intersect determination range to be shorter in length in a front-rear direction of the host vehicle when the traveling direction of the host vehicle is a left turn than when the traveling direction of the host vehicle is a right turn.

6. An alerting apparatus that issues an alert regarding a moving obstacle to a driver of a host vehicle, when the host vehicle enters an intersection of a crossroad that is connected to a traveling road on which the host vehicle is traveling, and the traveling road, the alerting apparatus comprising:
an ECU configured to determine a traveling direction of the host vehicle entering the intersection; obtain position information of the moving obstacle; estimate a path of the moving obstacle, based on the position information of the moving obstacle; determine whether the path of the moving obstacle intersects with a preset intersect determination range that extends out in front of the host vehicle from the host vehicle; issue the alert regarding the moving obstacle to the driver when it is determined that the path of the moving obstacle intersects with the intersect determination range; set a timing of the alert regarding the moving obstacle to an earlier timing when the moving obstacle is positioned on a left side of the host vehicle than when the moving obstacle is positioned on a right side of the host vehicle, when the traveling direction of the host vehicle is a left turn; and set the timing of the alert regarding the moving obstacle to an earlier timing when the moving obstacle is positioned on the right side of the host vehicle than when the moving obstacle is positioned on the left side of the host vehicle, when the traveling direction of the host vehicle is a right turn.
