Definitions
- the invention relates to a device for monitoring the state of a vehicle driver according to the preamble of claim 1.
- Driver condition monitoring system for motorized Vehicle discloses that outputs visual or acoustic signals to the driver and determines visual, acoustic or haptic reactions of the driver to determine the driver's attention.
- An electronic unit which is preferably integrated in existing vehicle safety systems, controls the activation of the visual or acoustic signals and determines suitable procedures based on the driver's reaction.
- the system also includes auxiliary sensors that can be used to control and change the function of the system to avoid its unnecessary activation.
- Both described embodiments have in common that the driver is exposed to a deliberate test situation which can be perceived as disturbing under certain circumstances.
- the object of the invention is to provide a device for monitoring the condition of a vehicle driver, in which a condition test is perceived by the vehicle driver to be comparatively less disruptive.
- the invention is based first of all on a device for monitoring the condition of a vehicle driver of a vehicle, which comprises means for outputting a test stimulus, such as a test signal or a test question, and an evaluation unit for determining the reaction of the vehicle driver to the test stimulus.
- a test stimulus such as a test signal or a test question
- an evaluation unit for determining the reaction of the vehicle driver to the test stimulus.
- a first essential aspect of the invention is that the test stimulus is output in a form that is also part of a requirement situation for the vehicle driver in a conventional driving sequence, so that the vehicle driver consciously perceives the test stimulus, but does not immediately understand it as a test stimulus.
- the test stimulus is, so to speak, mixed into the normal sequence of driving a vehicle without immediately being noticed as a test stimulus.
- the test stimulus can simultaneously represent an actual requirement situation, ie a response or reaction is actually required from the vehicle driver in the driving sequence.
- test stimulus can also be generated especially for the test without the driver having to react to the immediate driving sequence.
- care must be taken that the test stimulus is "camouflaged" so to speak, so that the vehicle driver does not immediately have the feeling that he is in a test situation.
- the advantage of these approaches is that the test stimulus is not perceived as disturbing in a way that the driver has thoughts in a way, "Why am I being tested?" or "Another test '.”.
- a test stimulus can consist, for example, of asking the driver to give a conscious answer to a question addressed directly to him, such as "Should the navigation route be maintained despite the current traffic situation?", "Should a certain assistance system be activated (e.g. ACC) or its Parameters are changed? ".
- These questions could also be part of a conventional driving process, so that the driver is hardly able to identify such questions as test questions and therefore find them annoying. Rather, the driver assumes that answering the questions is part of the conventional driving process, which is actually the case, although testing is carried out at the same time. In this case, test and actual requirements situation can be advantageously connected.
- the test stimulus is output in a form that the driver unconsciously requests, in particular reflex reactions.
- This measure also has the advantage that the driver does not immediately see himself in a test situation, which can be perceived as annoying.
- This test form can e.g. are acoustic or visual stimuli to which the driver responds or responds with a physiological reflex (e.g. skin temperature change, head movement or the like).
- a physiological reflex e.g. skin temperature change, head movement or the like.
- the test stimulus can also include a haptic stimulus.
- a small bump on the steering wheel simulates a bump in the road, which provokes or requires a corresponding steering movement to compensate for this disturbance.
- the figure shows a schematically illustrated control loop which is intended to illustrate the mode of operation of a device according to the invention for monitoring the condition of a vehicle driver.
- the problem of monitoring the driver's condition can be understood as a control technology task in which the response to a defined test signal is examined in order to obtain information about the system properties of the controller, in the present case the driver.
- a change in the system properties of the controller through a change in the behavior of the vehicle driver gives indications of a changed driver's condition.
- 1 denotes a unit for driver status detection.
- the driver status detection unit 1 outputs a test stimulus via an output device 2 to a vehicle driver 3, which is symbolized by the arrows 1a and 2a.
- the arrow 3a pointing away from the rectangle standing for the vehicle driver illustrates a reaction of the vehicle driver 3, which is detected by a reaction detection unit 4 and passed on to the driver status detection unit 1 for evaluation (see arrow 4a).
- the driver's condition is determined in the driver's condition detection unit 1 as a function of the reaction of the vehicle driver 3. This can trigger a given test stimulus or other measures.
