Definitions

  • the invention relates to a device for warning that a motor vehicle driver is falling asleep according to the preamble of claim 1.
  • Such a device is known for example from DE 33 00 086, in which means optical sensors due to the different reflectance the white boundary lines the road surface and when the outer boundary line is exceeded warns the driver. It is also proposed that the lane boundary lines be analogous capture so that when leaving the lane to the left or right to fall asleep is closed. For reliable detection of the boundary lines even in the dark In addition, a light source is used, which is aligned in the direction of the boundary lines becomes. The main disadvantage of the device is that it is on the white road markings is instructed.
  • DE 197 15 519 describes a device for estimating a drowsiness level of a motor vehicle driver known which is an image recording means for recording images a driver's face area of blinking the driver's eye from the image data of the image recording medium.
  • the device further comprises a detection means to record an elapsed time during blinking as blink duration in Agreement with the facial area image data by the image recording medium are obtained, a receiving means for obtaining a frequency distribution of the Blink duration that during a first predetermined period after a start of the Driving operation of the vehicle is detected, a setting means for setting a threshold value in Match the frequency distribution for extracting the slow blink of the Eye, a calculation means for calculating an occurrence ratio of the slow Blinking during every other predetermined period of time, the appearance ratio is set by the ratio of a number of blinking operations with a duration, whose values are not less than the threshold in relation to a total number of blink times during the second predetermined period and a discriminating means to distinguish the level of drowsiness of
  • a disadvantage of the device is that in the case of spectacle wearers, the image recording medium due to the reflections not reliably the driver's eye movements can capture.
  • Behavior parameter detection means for detecting a behavior parameter which is characteristic of an amount of behavior related to a yaw movement and / or lateral movement of the vehicle
  • vehicle speed detection means for detecting a speed of the vehicle
  • Reference behavior parameter setting means for setting a reference behavior parameter based on changes in the behavior parameter
  • Lateral deviation behavior amount calculating means for calculating a lateral deviation behavior amount of the vehicle based on the behavior parameter, the reference behavior parameter and the speed of the vehicle
  • driving state determination means for determining whether or not the driver's driving state is normal based on the lateral deviation behavior amount
  • Abnormality determining means which is responsive to a determination made by the driving condition determining means that the driving condition of the driver is abnormal, to determine that the driving condition of the driver is abnormal.
  • a yaw rate sensor for detecting the yaw rate is provided to determine a reference line.
  • the determined yaw rate is integrated over time and a yaw angle is derived from it.
  • a reference line is then calculated from the yaw angle using the square error method.
  • a differential lateral deviation can then be determined and processed on the basis of this reference line.
  • a disadvantage of the known device is its extremely complex structure, which makes the device very susceptible to errors. Another disadvantage is the use of unifunctional sensors, which complicates the design of the electronic electrical system.
  • an alternative solution for the yaw rate sensor is proposed in the publication, this also requires unifunctional sensors such as, for example, a lateral acceleration sensor.
  • the invention is therefore based on the technical problem of creating a device for warning the driver to fall asleep, which can essentially fall back on sensors that are already available in the motor vehicle.
  • the distance sensor system is composed of a large number of distance sensors, preferably laser and / or radar sensors, together which the Fully scan the surroundings of the vehicle, whereby additional information of the Let the vehicle environment win. For example, from the existence from oncoming traffic and from its speed draw conclusions about what for a road the vehicle is, how many lanes are available and how the lane is wide without the lane needing to be explicitly determined.
  • the devices for detecting a Reference driving style of the motor vehicle driver and / or the comparison logic as fuzzy logic and / or designed as a neural network.
  • the invention is explained in more detail below on the basis of a preferred exemplary embodiment explained.
  • the single figure shows a schematic block diagram of a device for A driver's sleep warning.
  • the device 1 for warning a driver of falling asleep comprises a driver Distance sensors 2, an evaluation unit 3, a navigation system 4, a device 5 for Detection of a reference driving style, a comparison logic 6 and a warning device 7.
  • the device 1 has the personal driving style of a motor vehicle driver learn to safely detect significant differences from driving style before going to sleep.
  • the device 5 for detecting a reference driving style detects an actuation signal the accelerator pedal 8, a brake pedal 9 and a direction indicator 10.
  • the distance sensor 2 which is designed, for example, as a laser and / or radar sensor is a corresponding radiation and receives radiation components reflected by objects. Due to the shape and the duration of the received radiation can be the evaluation unit 3 on the type and distance of the surrounding objects and thus on the Environment in general.
  • this learning phase it is now registered how much lateral own movement of the motor vehicle driver usually has in his driving style and other significant style features.
  • the detection of the reference driving style can be done using Maps or by means of fuzzy rules and / or by means of neural networks are, which are then adaptively adapted to changes in driving style if necessary. If such a reference driving style has now been learned, the distance sensor system 2 continuously detects the objects surrounding the motor vehicle.
  • the evaluation unit determines from the data 3 first the respective lane boundaries. Furthermore vehicles of the Oncoming traffic identified based on the negative relative speed. Based on Total width of the road, the speeds measured and the presence of the Oncoming traffic can then be concluded based on the type of road. It also receives the evaluation unit 3 data from a navigation system 4 to the knowledge obtained to complete or compare with the environment.
  • the Evaluation unit a lateral movement of the motor vehicle on one of the driving limits too, it is compared in the comparison logic 6 with the reference driving style. He follows during the comparison an actuation of the direction indicator 10 or a controlled one Actuation of the accelerator or brake pedal 8, 9, can be a desired action of the Motor vehicle driver are closed so that the further comparison can be set can. Otherwise, the comparison with the reference driving style is continued and if it is exceeded the warning device 7 is triggered by a threshold value. The warning device 7 generates then a haptic, acoustic and / or visual warning to the motor vehicle driver, that he is falling asleep.
