Definitions
- the application relates to a measuring system for detecting the environment and a method for operating such a measuring system.
- Measuring systems for detecting the environment are used in vehicles, for example. Such measuring systems can be based on electromagnetic waves.
- Modern vehicles have a variety of measuring systems, also known as sensors, whose data is used to provide information to the driver and/or to driver assistance systems.
- the measuring systems record the surroundings of the vehicle and other road users. Based on the recorded data, a model of the vehicle's environment can be created and changes in this vehicle environment can be responded to.
- Measuring systems are constantly being developed for various functions, e.g. for the acquisition of environmental information in the near and far range of vehicles, such as passenger cars or commercial vehicles.
- Measuring systems can also serve as sensor systems for driver assistance systems, in particular assistance systems for autonomous or semi-autonomous vehicle control. They can be used in particular to detect obstacles and/or other road users in the front, rear or blind spot area of a vehicle.
- Measuring systems can be based on various sensor principles, such as radar, ultrasound, optics.
- a Lidar sensor has an optical transmitter unit and an optical receiver unit.
- the transmitter unit can send out an optical transmission signal, which can be continuous or pulsed.
- the optical Transmission signal can be modulated.
- electromagnetic waves in the form of laser beams in the ultraviolet, visual or infrared range can be used.
- the receiving unit can receive the light after reflection from an object in a monitoring area in the vicinity of the lidar sensor.
- the optical reception signal can be evaluated using the optical transmission signal, e.g. according to a time-of-flight method, and the spatial position and distance of the object at which the reflection occurred can be determined. It is also possible to determine a relative speed.
- reflection or reflected light is understood to mean any light that is thrown back and should in particular also include light that is thrown back by scattering or absorption emission.
- a radar sensor has a transmitting unit for a radar transmitting signal and a receiving unit for a radar receiving signal.
- the receiving unit can receive the radar signal after it has been reflected from an object in a monitoring area in the vicinity of the radar sensor.
- the radar receiving signal can be evaluated using the radar transmitting signal and information about the object on which the reflection occurred can be determined.
- Radar sensors can also be used in vehicles to detect blind spots and can be installed in side mirrors for this purpose, for example.
- US 2018/0149742 Al describes a sensor unit that is mounted on the roof of a vehicle and contains both radar and lidar sensors.
- the sensor unit can rotate so that both the radar and lidar sensors are rotated so that both the radar and lidar sensors detect the environment over the entire horizontal plane over the duration of one revolution.
- a measuring system for environmental detection has an optical sensor system for environmental detection and a radar sensor for environmental detection
- the optical sensor system is designed to detect the environment using optical signals, whereby the optical sensor system has a deflection device for the optical signals.
- the deflection device has a rotating body.
- the radar sensor is arranged on the rotating body in such a way that the environment can be scanned by the radar sensor in a first direction for detecting the environment by rotating the rotating body.
- the rotating body can also be referred to as a rotor, for example.
- the optical signals can in particular comprise optical transmission signals and/or optical reception signals.
- the optical sensor system can have an optical transmission unit with a light source for transmitting the optical reception signals and an optical reception unit with a reception sensor for receiving the optical reception signals.
- the radar sensor can have a transmission unit for transmitting radar transmission signals and a reception unit for receiving radar reception signals.
- Such a measuring system has the advantage that the radar sensor can use the rotary movement of the deflection device to scan the environment.
- the radar sensor itself can therefore be constructed more simply.
- a separate deflection device for the radar sensor can be dispensed with for scanning in the first direction.
- the radar sensor can perform the rotational movement together with the rotating body. This can create a cooling effect on the radar sensor, which is caused by the flow around it. This can make it possible to dispense with further cooling measures on the radar sensor, which can result in cost savings.
- the deflection device has a rotating mirror device with at least one mirror surface, wherein the at least one mirror surface can be connected to the rotating body and in particular can be attached to it.
- the at least one mirror surface can have essentially reflective properties with respect to the wavelength of the optical sensor system and can be designed to be at least partially transparent to the wavelengths of the radar sensor.
- the at least one mirror surface can also be designed as a selective bandpass filter and/or based on a very thin metal layer. Due to the rotational movement of the Rotating body, the optical signals of the optical sensor system are deflected in their direction for the purpose of detecting the environment. The deflection can affect optical transmission signals and/or optical reception signals.
- the optical sensor system can in particular comprise a lidar sensor, which works, for example, with optical signals that include laser light.
- the deflection device is arranged in the optical transmission path and/or in the optical reception path of the optical sensor system.
- the optical transmission path is the path that the optical transmission light travels after being emitted by the light source on its way into the environment until it is reflected on an object, for example.
- the optical reception path is the path that the optical reception light travels after being reflected on an object, for example, before being received by the reception sensor.
- the environment can be scanned by the optical sensor system, particularly in the first direction, for detecting the environment due to the rotary movement of the rotating body. Due to the rotary movement of the rotating body, the optical transmission signals of the optical sensor system are gradually deflected in their angular direction for the purpose of detecting the environment. As a result, the optical transmission signals gradually impinge on objects in the environment, for example, with a small offset that depends on the deflection by the deflection device.
- the scanning can also be referred to as scanning.
- the radar sensor is arranged on the rotating body in such a way that its scanning of the environment precedes the scanning of the environment by the optical sensor system in the first direction.
- precedence means that radar transmission beams, in connection with the rotary movement of the rotating body, hit points or areas at certain angles of the environment before the optical transmission beams. This makes it possible to incorporate findings obtained from the environment detection by the radar sensor into the environment detection by the optical sensor system.
- At least one parameter of the optical sensor system depends on the environmental detection by the radar Sensor. For example, if the radar sensor detects an impairment of the optical environment detection, the strength of the optical transmission signal emitted can be increased.
- the transmission characteristic of the radar transmission signal runs transversely, in particular perpendicularly, to the at least one mirror surface of the rotating mirror device. This allows the radar transmission signal to scan the environment, for example, in the same direction as the optical transmission signal.
- the transmission characteristic of the radar transmission signal has two main directions, each of which runs transversely, in particular perpendicularly, to the at least one mirror surface. This could, for example, relate to a radar sensor that has two "main lobes" in the characteristics of its transmission signal. These two main lobes could, for example, be directed in opposite directions.
- the transmission characteristic of the radar transmission signal is wider in a second direction transversely, in particular perpendicularly, to the first direction than in the first direction.
- the widening can in particular relate to the direction transversely, e.g. perpendicularly, to the scanning direction. In the case of a horizontal scanning direction, this can mean a widening in the vertical direction.
- the radar sensor has a further deflection device for the radar transmission signal, by means of which the environment can be scanned in a third direction by the radar sensor.
- the scanning in the third direction is effected by the further deflection device for the radar sensor.
- the further deflection device can, for example, comprise a phase array, by means of which the radar transmission signal can be deflected in the third direction such that, for example, the vertical direction is scanned by the radar sensor in addition to the horizontal direction.
- the third direction can in particular correspond to the vertical direction.
- a further radar sensor is arranged on the rotating body in such a way that the rotational movement of the rotating body the environment can be scanned by the additional radar sensor. This makes it possible to use the rotating body to scan the environment for additional radar sensors.
- the environment is scanned by the optical sensor system for detecting the environment.
- mirror surfaces attached to the rotating body of the deflection device of the optical sensor system are used to deflect the optical transmission beams emitted by the optical transmission unit and thus to carry out a scan of the environment.
- the scanning is carried out by the rotary movement of the rotating body.
- the scanning of the environment by the radar sensor precedes the scanning of the environment by the optical sensor system. In one embodiment of the method, this allows at least one parameter of the optical sensor system to be adjusted depending on the scanning by the radar sensor. This can, for example, relate to the strength of the optical transmission signal if, for example, a blockage in the transmission path of the optical transmission signal has been detected by the radar sensor moving ahead with its transmission beam.
- a vehicle can have the measuring system described.
- the measuring system can be used in the vehicle to detect the environment and exchange information with control and regulation systems arranged in the vehicle.
- actuators of the vehicle can be controlled and thus, for example, autonomous and/or partially autonomous driving functions can be implemented.

- Fig. 7 schematically shows a flow diagram of an embodiment of a method for operating the measuring system.
- Figure 1 shows a schematic of a measuring system 10, which can be used, for example, for environmental detection in a vehicle 100.
- the measuring system 10 has an optical sensor system 12, which can include a lidar system, for example.
- the optical sensor system 12 sends out an optical transmission signal LTX for detecting the environment through an optical transmission unit.
- the optical sensor system 12 also has an optical reception unit, which is designed to receive an optical reception signal LRX.
- the evaluation of the optical transmission signal LTX and the optical reception signal LRX can be carried out, for example, in a control unit, which can have memory and a computing unit.
- the control unit can be arranged, for example, in the optical sensor system 12 and/or at another location in the measuring system 10.
- the optical sensor system 12 is designed to detect the surroundings of the measuring system 10 by scanning. During scanning, the optical transmission signal LTX is guided over the surroundings by a step-by-step angle change in a scanning direction in the first direction 28. Reflections from objects in the surroundings, for example, reach a receiving sensor of the optical sensor system 12 as an optical reception signal LRX and can be evaluated together with the optical transmission signal LTX.
- the scanning of the environment is carried out by deflecting the optical transmission signal LTX by an optical deflection device 20, which has a rotating body that is mounted so that it can rotate about at least one axis.
- the optical deflection device can, for example, be made up of optical elements such as at least one lens and/or at least one prism.
- An optical phase array can also be used as the deflection device 20.
- the deflection device 20 comprises a rotating mirror arrangement.
- the rotating mirror arrangement has two mirror surfaces 24.
- the optical transmission signal LTX can be deflected at the mirror surfaces 24 to detect the surroundings and scan the surroundings. Reflected light in the form of the optical reception signal LRX can also be deflected by the mirror surfaces 24 and directed to a reception sensor of a reception device of the optical sensor system 12.
- the rotating mirror device is mounted so as to be rotatable about an axis. In the embodiment shown, the rotating mirror device can rotate about its axis in a first direction 28. Embodiments are also conceivable in which the rotating mirror device executes a pivoting movement.
- the measuring system 10 further comprises a radar sensor 14.
- the radar sensor detects the surroundings of the measuring system 10 by transmitting a radar transmission signal RTX and receiving a radar reception signal RRX.
- the characteristic 16 of the radar transmission signal RTX depends on the antenna design of the Radar sensor 14.
- the wavelengths of radar signals can be in the microwave range, for example.
- the radar transmission signals RTX emitted by a radar transmission unit can, for example, be reflected by objects in the vicinity of the measuring system 10 and received again as radar reception signals RRX by a reception unit of the radar sensor 14.
- By evaluating the radar transmission signal RTX and radar reception signals RRX information about the environment can be determined. In particular, objects in the environment can be determined, possibly together with other properties of the objects.
- the radar transmission signal RTX and the radar reception signal RRX can be evaluated in a control unit, for example.
- the control unit can be arranged in the radar sensor 14.
- the control unit can also be arranged elsewhere in the measuring system 10. It is also possible to carry out the evaluation of the radar transmission signal RTX, the radar reception signal RRX and the optical transmission signal LTX, the optical reception signal LRX together in a control unit. This can then be arranged, for example, in the optical sensor system 12 and/or in the radar sensor 14 and/or at another location in the measuring system 10.
- the rotating mirror system 20 has a holding device 22 on which the mirror surfaces 24 and the radar sensor 14 are arranged.
- the holding device 22 can form the rotating body of the deflection device 20.
- the radar sensor 14 is arranged on the holding device 22 such that it rotates together with the mirrors 24 about the axis of the deflection device 20 in the direction of rotation 28.
- the measuring system 10 has a casing 26 that partially surrounds the deflection device 20.
- the casing 26 has the function of protecting the measuring system 10 from environmental influences.
- the casing 26 is, for example, impermeable to light.
- the casing 26 therefore has an opening through which the optical transmission signal LTX is sent and the optical reception signal LRX is received.
- the radar transmission signal RTX is also sent through the opening and the radar reception signal RRX is received through the opening.
- Figure 2 shows a further embodiment of the measuring system 10.
- the optical sensor system 12, which is also part of the measuring system 10 shown in Figure 2, is not shown in Figure 2.
- the radar sensor 14 shown in Figure 2 has transmission characteristics 16 of the radar transmission signal RTX, which radiate in two directions.
- the two transmission characteristics 16 are arranged so that they radiate in opposite directions. This is possible, for example, by using one antenna design per direction. Alternatively or additionally, it is possible to use an antenna design with a dipole radiation characteristic.
- the casing 26 can in particular be designed such that radar beams are reflected by it. In this way, one of the transmission characteristics 16 can radiate directly towards the surroundings and the other transmission characteristic 16 can be reflected by the casing 26 and also contribute to the detection of the surroundings by the radar sensor 14.
- the deflection device 20 is also designed as a rotary play system with the mirror surfaces 24.
- the deflection device 20 has the rotating body, which has the holding device 22.
- the deflection device 20 is mounted so that it can rotate about its axis. In the example shown, the deflection device 20 can rotate in the first direction 28, the direction of rotation. Since the radar sensor 14 is arranged on the deflection device 20 in such a way that it carries out the rotational movement together with the deflection device 20, its radar transmission signal RTX also carries out a rotational movement and scans the surroundings of the measuring system 10 through this rotational movement.
- the deflection device 20 it is also possible for the deflection device 20 to perform a swiveling movement around its axis. Accordingly, the radar transmission signal RTX would scan the surroundings in a swiveling manner. By deflecting the optical transmission signals on the mirrors 24, the surroundings can also be scanned by the optical sensor system 12 (not shown in Figure 2). In the example shown, the scanning of the surroundings by the radar sensor 14 and by the optical sensor system 12 takes place in the same first direction 28.
- the transmission characteristic 16 of the radar sensor 14 can be arranged in the direction of rotation 28 such that the scanning of the radar Sensor 14 runs ahead of the scanning of the optical sensor system 12.
- the radar sensor 14 can then be used to determine whether something is blocking the optical propagation path of the optical transmission signal LTX and/or the optical reception signal LRX. This can then be responded to by, for example, changing a parameter of the optical sensor system 12.
- the change in the parameter can, for example, mean an increase in the transmission power of the optical sensor system 12. In the case of a lidar sensor, this can mean that a transmission laser of the lidar sensor emits with higher power.
- FIG 3 shows an example of a possible scanning 32 by the optical sensor system 12.
- the horizontal plane H is shown for a vehicle 100, which has a measuring system 10 in which the deflection device 20 is mounted so that it can rotate about the axis that runs perpendicular to the horizontal H.
- the lines of the scanning 32 therefore move step by step during the scanning with an angular offset in the direction of rotation 28 of the deflection device 20.
- the height 30 of the vertical V of the scanning 32 of the optical sensor system 12 can be achieved, for example, by optically widening the optical transmission signal LTX. This leads to the line-shaped scanning patterns 32 shown in the surroundings of the vehicle 100.
- the scan 32 by the optical sensor system 12 is superimposed on the scan 34 by the radar sensor 14.
- a circle 34 shows the scan at the current time.
- Other circles show the scan at later times.
- the scan of the radar sensor 14 initially scans a height 30 in the vertical V from top to bottom.
- a vertical area next to the previously scanned area is then scanned step by step by the circles shown in dashed lines.
- scanning is carried out step by step from top to bottom over a height 30.
- the circle shown with a solid line shows the current scan 34, while the circles shown with a dashed line show scanning areas from earlier in time.
- the same area of the environment can be scanned by the described measuring system 10 with the described method by the optical sensor system 12 and the radar sensor 14. It is possible to install the two sensors compactly in the measuring system 10, whereby optionally only one rotating body needs to be provided.
- FIG 4 shows another example of a scanning pattern of the measuring system 10.
- the scanning 32 by the optical sensor system 12 is shown by the lines, which scan the scanning area step by step in the direction of rotation 28.
- the surroundings of the measuring system 10 are scanned by the radar sensor 14.
- the transmission characteristic 16 of the radar transmission signal RTX is expanded in the vertical direction V, so that in the example shown it reaches the height 30.
- This enables a simultaneous scanning 36 of the vertical with a height 30 by the radar sensor 14.
- the current scanning 36 by the radar sensor 14 is shown with solid lines. Circles shown with dashed lines show a scanning range of the radar sensor 14 that lies in the past. It can be seen that the scanning 36 of the radar sensor 14 also moves in the direction of rotation 28 of the rotating body of the deflection device 20, and thus carries out the scanning 36.
- the rotation and thus the scanning 34, 36 in the direction of rotation 28 takes place in the horizontal H.
- the optical scanning 32 by the optical sensor system 12 in the vertical V takes place by an optical transmission signal LTX expanded in the vertical V.
- the radar transmission signal RTX is also expanded in the vertical V.
- the radar sensor 14 also scans step by step in the vertical direction V.
- Figure 5 shows a schematic view of the vehicle 100 with the measuring system 10 in a side view.
- the measuring system 10 is arranged in a front area of the vehicle 100.
- the height 30 at which the scanning of the surroundings can take place by the radar sensor 14 and/or the optical sensor system 12 is indicated schematically.
- the optical transmission signal LTX also shown schematically are the optical transmission signal LTX, the radar transmission signal RTX, the optical reception signal LRX and the radar reception signal RRX.
- the axis of the deflection device 20, around which the deflection device 20 rotates, runs in the image plane here.
- the direction of rotation 28 runs perpendicular to the image plane in the example shown.
- the scanning direction 28, also The scanning direction, referred to as the scanning direction, runs in the direction of rotation 28 along the horizontal direction in front of the vehicle 100.
- the scanning 32, 34 in the vertical V can be carried out as described in relation to Figure 3 or 4 by expanding the transmission signals LTX, RTX and/or in addition to the scanning 32, 34 in the horizontal H, a step-by-step scanning 36 of the environment can also be carried out in the vertical V.
- Both the optical sensor system 12 and the radar sensor 14 can optionally also scan step-by-step in the vertical direction V.
- FIG 6 the vehicle 100 from Figure 5 is shown schematically in a top view.
- the first direction 28 is shown, which corresponds to the direction of rotation 28 of the deflection device 20 of the measuring system 10.
- the first direction 28 runs horizontally in front of the vehicle 100.
- Figure 6 also shows the radar transmission signal RTX and the radar reception signal RRX. It can be seen that the radar transmission signal RTX precedes the optical transmission signal LTX.
- FIG. 7 shows a schematic flow chart of an embodiment of the method for operating the measuring system 10.
- the environment is detected by the radar sensor 14.
- the environment detection of the radar sensor 14 in step S1 is used to determine whether there are objects in the environment that influence, in particular impair, the detection of the environment by the optical sensor system 12. Parameters of the optical sensor system 12 can then be adjusted accordingly in step S3. If the environment detection is impaired by For example, the optical sensor system 12 can increase the transmission power of a laser of a lidar system and thus increase the probability of detection by the lidar system.
