JC,
There is an understandable similarity in the description of the equipment as that is generally how it needs to work. But in Toyota's case, this is merely setting the stage. But when you read their patent - it is only covering a tiny element - just using the driver's attention to the Blind Spot warning light! Do they look when they see the warning, or do they miss or ignore the warning. That is it!
1. A driver monitoring system comprising:
an image capturing device capturing a face of a driver of a vehicle to generate a facial image of the driver; and a processor configured to detect an angle of a facial orientation or a line of sight of the driver based on the facial image, and judge distracted driving by the driver based on the angle, *wherein the vehicle is provided with at least one indicator showing a presence of a surrounding vehicle in a rear lateral area of the vehicle*, and when the indicator is turned on, the processor is configured to ease a condition for judging distracted driving concerning a predetermined angular range when the driver looks at the indicator.
2. The driver monitoring system according to claim 1, wherein the processor is configured to judge that the driver is driving while distracted if the angle is outside a threshold range for equal to or greater than a threshold time, and broaden the threshold range so that the predetermined angular range is included in the threshold range when the indicator is turned on.
3. The driver monitoring system according to claim 1, wherein the processor is configured to judge that the driver is driving while distracted if the angle is maintained within the predetermined angular range for equal to or greater than a first threshold time when the indicator is not turned on, and judge that the driver is driving while distracted if the angle is maintained within the predetermined angular range for equal to or greater than a second threshold time when the indicator is turned on, and the second threshold time is longer than the first threshold time.
Every step forwards is progress, even if it is a tiny step; and when it comes to blocking competitors, every potential patent is secured so that tiny step becomes a mighty wall!
