Abstract
An in-vehicle alert apparatus includes a camera sensor, a radar sensor, a display unit, and an electronic control unit. The electronic control unit specifies a position and a relative speed of an object by selectively using any of a fusion method and a camera-alone method. The electronic control unit extracts an obstacle and calculates a margin time period in which the obstacle reaches a tip end region of a host vehicle. The electronic control unit displays an alert screen that guides driver's line of sight in a direction of the obstacle having the margin time period less than or equal to a threshold. The electronic control unit prohibits display of a new alert screen while a first predetermined time period elapses from switching to the camera-alone method, and while a second predetermined time period elapses from switching to the fusion method.
