Abstract:
1. A driving ability reduction determining apparatus comprising: head-up display device that emits a determination-usage display image, which is preset for determining driving ability reduction of a driver of a vehicle, toward a windshield arranged ahead of the driver, and that displays to the driver the determination-usage display image as a virtual image through the windshield in a manner that the driver visually recognizes the determination-usage display image over an actual scene ahead of the vehicle; and an operation portion that is operated by the driver when the driver visually recognizes the determination-usage display image; a response detection portion that detects a response situation of the driver's operation of the operation portion in response to display of the determination-usage display image by the head-up display device; a driving ability determination portion that determines a degree of the driving ability reduction of the driver based on a detection result of the response detection portion; and a controller that calculates a response score based on the detection result of the response detection portion, wherein a three dimensional space ahead of the vehicle is divided in both a left-to-right direction and a near-to-far direction, and the controller calculates a response score for each divided space ahead of the vehicle.
