WARNING DEVICE FOR VEHICLE

摘要

When a warning is generated for a driver of a host vehicle based on approach information about a moving object, a selection between a first warning method and a second warning method is determined in accordance with the moving direction of the moving object with respect to the host vehicle. In the first warning method, a predicted collision time, which is the predicted amount of time before the moving object will collide with the host vehicle, is calculated based on the approach information, and the driver is warned only when the predicted collision time is less than a threshold value. In the second warning method, the distance between the moving object and the host vehicle is obtained as the approach information, and the driver is warned only when that distance is a value that corresponds to a value within a warning range.

主权项

1. A warning device for a vehicle that generates a warning for a driver of a vehicle based on approach information about a moving object approaching the vehicle, the device comprising:
a first warning section that calculates a collision prediction time, which is time predicted to elapse before a collision between the moving object and the vehicle, based on the approach information about the moving object, and generates a warning for the driver if the collision prediction time is less than a threshold value; a second warning section that obtains a distance between the moving object and the vehicle as the approach information about the moving object and generates a warning for the driver only when the distance is a value in a warning range; and a switching section that switches the warning section employed to generate a warning for the driver between the first warning section and the second warning section in accordance with a moving direction of the moving object with respect to the vehicle.
