摘要： A driving ability reduction determining apparatus comprising a virtual image display portion, an operation portion, a response detection portion and a driving ability determination portion is disclosed. The virtual image display portion emits a determination-usage display image toward a windshield, thereby displaying to the driver the determination-usage display image as a virtual image through the windshield. The operation portion is operated by the driver when the driver visually recognizes the determination-usage display image. The response detection portion detects a response situation of driver's operation of the operation portion in response to display of the determination-usage display image by the virtual image display portion. The driving ability determination portion determines the driving ability reduction of the driver based on a detection result of the response detection portion.

摘要： A driving assistance device that performs a notification process for notifying a driver of a risk of a collision with a preceding vehicle in cooperation with a notification device includes: an inter-vehicular distance acquisition section that successively acquires an inter-vehicular distance; a first index calculator that calculates a first risk index indicating a degree of the risk of the collision based on a traveling speed and the inter-vehicular distance; a second index calculator that successively calculates a second risk index based on a relative speed between the own vehicle and the preceding vehicle; a notification level determination section that successively determines a notification level indicating a strength of notification for notifying the risk of the collision, based on the first risk index and the second risk index; and a notification processor that performs the notification process in a notification mode corresponding to the notification level.
