Embodiment Construction

[0045] Techniques for monitoring vehicle driver concentration will be described below. These techniques include determining the duration based on the vehicle speed. Compare the duration to the driver's blink time. If the blink is longer than the duration, the driver can be considered less attentive. If the eyelid closure persists, the driver's level of concentration is severely reduced, which can be referred to as, for example, drowsiness.

[0046] The blink time may be referred to as, for example, eyelid closure time, ie the duration during which the driver's eyelids are in a closed state. Alternatively or in addition, blink time can also be referred to as eye closure time, which is the amount of time it takes for the eyelids to switch between open and closed states. In one embodiment, for example, only the eyelid closure time or eye closure time can be monitored. In another embodiment, not only the eyelid closure time but also the eye closure time can be monitored. The ...

Abstract

To monitor an attention degree (302) of a vehicle driver, a period (330) is determined on the basis of a speed of the vehicle. It is determined whether an eyelid closed time (301) and / or an eyelid closing time of the driver exceeds the period (330).

Description

technical field [0001] The invention relates to a method of monitoring the driver's attentiveness of a vehicle and to a corresponding device. In particular, the present invention relates to techniques for determining whether a driver's eyelid closure time exceeds a duration. Background technique [0002] For example, techniques for checking the driver's concentration on the basis of the steering behavior and travel time of the driver of a motor vehicle are already known. However, there may be situations where the time-dependent steering behavior is not sufficient to accurately and reliably monitor attentiveness, thereby endangering the driver or other road users. Especially when assisted by one or more driver assistance systems, this can lead to reduced concentration. Autonomous driving technologies, for example, in particular, are likely to seriously reduce driver concentration. However, even when the driver is adequately supported by one or more driver assistance system...
