Definitions
- the invention relates to a device for falling asleep a motor vehicle driver according to the preamble of claim 1.
- Such a device is known for example from DE 33 00 086, in the means of optical sensors due to the different reflectance the white boundary lines the roadway are detected and when exceeding the outer boundary line warns the driver. It is also proposed, analogous to the lane boundary lines capture, so that when you leave the lane to the left or right to fall asleep is closed. For reliable detection of the boundary lines even in the dark, a light source is used, which is aligned in the direction of the boundary lines becomes. The main disadvantage of the device is that this on the white lane markings instructed.
- From DE 197 15 519 is a device for estimating a degree of drowsiness of a motor vehicle driver It is known that an image recording means for recording images a face area of the driver of blinking the driver's eye from the image data of the image-recording agent.
- the device further comprises a detection means for detecting an elapsed time during a blinking blink time in Corresponding to the image data for the face area, which is captured by the image recording means a obtaining means for obtaining a frequency distribution of Blinking duration, which during a first predetermined period of time after a start of the Driving operation of the vehicle is detected, a setting means for setting a threshold in Correspondence with the frequency distribution for the extraction of the slow blinking of the Auges, a calculation means for calculating an occurrence ratio of the slow Blinking during every other predetermined time period, wherein the occurrence ratio is set by the ratio of a number of Blinzelvor réelle with a duration whose values are not less than the threshold value with respect to a total number of blink duration during the second predetermined time period and a discriminating means for discriminating the drowsiness of the driver in accordance with the calculated occurrence ratio.
- a disadvantage of the device is that in spectacle wearers due to the reflections the image recording medium not reliable the eye movements of the motor vehicle driver can capture.
- a yaw rate sensor for detecting the yaw rate is provided.
- the determined yaw rate is integrated over time and therefrom a yaw angle derived.
- a yaw angle then becomes Reference line calculated. Starting from this reference line can then be a differential Lateral deviation can be determined and processed.
- a disadvantage of the known device is their extremely complex structure, which makes the device very error prone.
- Another Disadvantage is the use of unifunktionalen sensors, what the training of the electronic on-board network complicates.
- unifunktionale sensors such as a lateral acceleration sensor.
- From DE 195 07 957 C1 is an optical scanning device for a lateral Roadway area known.
- the scanner allows runtime measurements, Contrast measurements and the detection of lane markings after the Triangulation. From sensor data, the distance to both the Lane marking as well as curbside calculated. Based on the data collected an audible warning signal is generated when there is a risk that the vehicle is at Maintaining the current driving style exceeds the side lane marking or this approaches to a minimum distance.
- US 4,829,434 relates to an automatic adaptation of driving characteristics to the Expectations and abilities of a driver. This is especially the dynamic driving behavior of the driver considered.
- DE 43 38 244 A1 describes a danger avoidance system for a vehicle, which in is able to avoid the collision of a vehicle against obstacles and the effect to reduce a collision on a vehicle.
- a Decision unit provided, which decides whether the driver of the system aware of dangerous driving mode.
- a sleep warning device which on a Speech recognition based.
- the device generates voice output on which the Driver must respond with a spoken answer.
- the spoken answers of Drivers are evaluated in order to attract attention d. H. one To determine the driver's wakefulness.
- the voice outputs and inputs can For example, be coupled with a navigation system.
- the invention is based on the technical problem of a device for falling asleep to create a motor vehicle driver, which is based essentially on existing sensors in the Motor vehicle can fall back.
- the distance sensor is composed of a plurality of Distance sensors, preferably laser and / or radar sensors, together, the Fully scan the environment of the vehicle, which provides additional information of the To win the vehicle environment. For example, from the presence of Oncoming traffic and from whose speed draw conclusions on what one Road is the vehicle, how many tracks are available and how wide the Lane is, without the lane needs to be determined explicitly.
- the means for detecting a Reference driving style of the motor vehicle driver and / or the comparison logic as fuzzy logic and / or formed as a neural network.
- FIGURE shows a schematic block diagram of an apparatus for Sleep alert of a motor vehicle driver.
- the device 1 for falling asleep a motor vehicle driver comprises a Distance sensor 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 in driving style before falling asleep.
- the device 5 for detecting a reference driving style detects an actuating signal the accelerator pedal 8, a brake pedal 9 and a direction indicator 10.
- the distance sensor 2 which is formed for example as a laser and / or radar sensor is, a corresponding radiation and receives reflected from objects radiation components. Due to the shape and the duration of the received radiation can by means of the evaluation unit 3 on the nature and distance of the surrounding objects and thus on the Environment generally closed.
- the distance sensor 2 which is formed for example as a laser and / or radar sensor is, a corresponding radiation and receives reflected from objects radiation components. Due to the shape and the duration of the received radiation can by means of the evaluation unit 3 on the nature and distance of the surrounding objects and thus on the Environment generally closed.
- this Lemphase is now registered how much lateral self-motion of the motor vehicle driver usually has in his driving style and other significant style features.
- the detection of the reference driving style can by means of Maps or stored by means of fuzzy rules and / or by means of neural networks are then adaptively adapted to changes in the driving style, if necessary.
- the distance sensor 2 detects continuously the objects surrounding the motor vehicle.
- the evaluation unit determines from the data 3 first the respective roadway boundaries. Furthermore, vehicles of the Oncoming traffic identified by the negative relative speed. Based on Total width of the carriageway, the recorded speeds and the presence of the Oncoming traffic can then be closed to the type of road. In addition, receives the evaluation unit 3 data from a navigation system 4, the knowledge gained about the environment to complete or with these match.
- the Evaluation unit a lateral movement of the motor vehicle on one of the travel limits to, 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 Actuation of the accelerator or brake pedal 8, 9, so may be on a voluntary 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 will continue and if exceeded a threshold, the warning device 7 is driven. The warning device 7 generates then a haptic, audible and / or visual warning to the motor vehicle driver, that this is falling asleep.
