Definitions
- the invention relates to a night vision device according to the preamble of the main claim.
- a device for improving the visibility in a motor vehicle is already known.
- a signaling device for example a monitor or a head-up display
- the driver of the motor vehicle is informed of driver information about the course of the road and / or about objects in the surroundings of the motor vehicle.
- an infrared-sensitive image sensor system is provided whose signals are processed in such a way that corresponding markings for limiting the course of the lane are superimposed into the display.
- the night vision device with the features of the main claim has the advantage that a struck or a beaten track of the vehicle by means of a positioning and / or a direction of travel sensor is determined. This makes it possible, even without an optical evaluation of the driving situation in front of the vehicle to give the driver an optical support in a representation of a night vision scenery in front of the vehicle. Thus, it is also possible to provide such information to the driver when an image evaluation, e.g. due to precipitation, poor visibility or missing road markings is not possible. In particular, it is advantageous to assist the driver in a night drive by evaluating data that is itself determined by a vehicle sensor system without having to carry out an optical image evaluation with a mostly high computational expenditure.
- the direction of travel sensor is a steering angle sensor. This makes it possible for the driver's current steering angle to be used for prediction of a travel path. Because the currently chosen steering angle can be displayed directly in the road ahead of the vehicle to project a lane course. The driver can thus recognize with which distance he will drive past a roadside or obstacles. Thus, he can also recognize whether a steering correction is required. This is particularly advantageous if the driver can only estimate distances to side obstacles poorly due to poor visibility.
- a position sensor to determine a current position of the vehicle and, e.g. from a comparison with a digital map or a
- the night-vision device determines the course of road boundaries and / or markings from a recorded camera image and also emphasizes these in the display. Compared to the rest, determined by the sensors
- Markings can thus be carried out a comparison between the optically detected and the otherwise detected markings by the driver. He can thus also estimate whether in fact a good detection of the route in front of the vehicle was carried out, or whether the support may be disturbed. If the taken track is compared with a track to be taken, the driver can recognize whether the steering wheel is set correctly to follow the track to be taken.
- FIG. 1 shows a night vision device according to the invention in a vehicle in a schematic plan view
- Figures 2 to 4 different embodiments for display representations of a night vision device according to the invention. - A -
- a motor vehicle 1 is shown schematically in a plan view.
- a camera 3 is arranged such that the camera 3 observes the driving space in front of the vehicle 1.
- the camera 3 is embodied in particular as an electronic camera device which, in addition to the wavelength range visible to the human eye, also covers the near infrared range.
- the camera 3 is preferably sensitive in a wavelength range between 400 and 980 nm.
- the camera 3 is designed, for example, as a CCD camera. Via a video line or a video data bus 4, the image data to a
- a lighting device 6 in which infrared light sources 7, e.g. Emit infrared light emitting diodes, light in the traffic ahead of the vehicle 1.
- the illumination device 6 is driven, for example, by the evaluation unit 5.
- the evaluation unit 5 has a computing unit 9 which, in a preferred embodiment, enables image processing of the recorded image data.
- the image data are forwarded by the evaluation unit 5 to a display unit 8 in the vehicle.
- the display unit 8 is designed, for example, as a so-called head-up display in the vehicle.
- a so-called contact-analogue display takes place, in which the projected image elements overlap with the scene visible to the driver through the windshield in front of the vehicle such that the overlaid markings for the driver lie in front of him with respect to the real objects appear.
- the display unit 8 may also be implemented as an indicator in a combination instrument or in a center console of the vehicle. Here, the corresponding scene in front of the vehicle is displayed in a screen.
- the evaluation unit 5 is provided with a steering angle sensor
- steering angle determines a steering angle of the front axle 19.
- the steering angle is adjusted by the driver via a steering wheel 18.
- detected via the steering angle sensor 10 steering angle calculates the evaluation unit 5 a track that the vehicle will perceive at an unchanged, set steering angle. This track is marked by markings into the picture taken by the camera 3. Thus, the driver can recognize the road ahead of the vehicle.
- the evaluation unit 5 is connected to a locating device 11.
- the locating device 11 has in particular an antenna 12, by means of which a satellite positioning is carried out. From the change of the spatial position, a motion vector can thus be determined first. For this movement vector is also a current, taken by the vehicle track determined and displayed in the display.
- a location in the sense of a determination of a change in location means of a wheel sensor
- these sensors can also be used to support the satellite order in the event that no satellite reception is possible.
- the locating unit can also be applied to a
- Road map base 13 access.
- This road map base 13 is e.g. executed in a memory stored digital map of a road network.
- the locating unit may determine a position of the vehicle on a road. But this also makes it possible to retrieve the further course of the road from the road map base.
- This road course is transmitted to the evaluation unit 5.
- the evaluation unit 5 now represents the further course of the road, starting from the current position of the vehicle, also overlapping the current driving situation in the display unit 8.
- the evaluation unit 5 is further connected to an operating unit 14.
- the camera 3 can be activated with the operating unit 14, but also the evaluation unit 5 can be informed which supplementary markings are to be displayed in the display 8.
- the embarked, with the steering angle sensor detected travel, the predetermined by the locating unit track or the locating unit in the
- the camera 3 can detect the scenery in front of the vehicle both day and night. In particular, however, their use as a night-vision device is advantageous because at night it is particularly difficult for a driver, especially in poor visibility, to recognize the road ahead of him.
- FIG. 2 shows a first exemplary embodiment for a representation in the display 8.
- a left-hand lane edge 21, a right-hand lane edge 22 and the intervening lane 20, including median markings 23, are visible to the driver in the image captured by the camera 3 and displayed in the display unit 8. If the display is in a head-up display with a contact-analogue display, the position of the camera image must be adapted to the actual configuration of the surroundings in front of the vehicle, as it is visible to the driver through the windshield.
- a lane is drawn by a left dashed line 24 and by a right dashed line 25, the determination of which is based on the currently set steering angle of the vehicle. The driver can thus recognize that he is currently without a vehicle
- FIG. 3 shows a further exemplary embodiment of a representation in the display unit 8.
- a line 26 is registered centrally in a traffic lane between a center lane marker 31 and a right lane edge 32. Further, in the display, a left lane boundary 33 and the
- Lane 30 itself shown.
- the course of the center track mark 31 and of the right-hand roadside edge 32 have been determined by analysis of the camera image. Therefore, according to an embodiment, markings 34 for highlighting the center strip and markings 35 for emphasizing the right-hand road boundary were additionally entered into the display image.
- the middle marking in the form of the line 26 can also be determined from a road course starting from the current position of the vehicle.
- the position of the vehicle is first determined in a road network and then determined, in particular taking into account the direction of travel of the vehicle, the expected road course and entered into the display device according to the illustration in Figure 3.
- a right-hand turn follows in the course of the road starting from the current position of the vehicle. This can be seen from a bending of the center line 26 to the right.
- a hint symbol 36 can also be entered in the display for assistance, which points the driver to a right turn. In special danger situations can additionally one
- Warning symbol 37 are displayed in the display, which also indicates the driver on a potentially dangerous route passage. This information can be stored in the road map base 13 to the respective street piece.
- FIG. 4 also shows a depiction 40 of a road course 41 which can also be used together with other exemplary embodiments.
- the course of the road 41 is shown in the form of a map representation or a small map detail in the display.
- the course of the road 41 is represented here in the direction of travel for a specific section which extends beyond the driver's current field of vision.
- a current position 42 of the vehicle is registered in relation to the road course 41.
- the map section 40 can be displayed in a center console display.
