Description

Device and method for checking sensors for a driver assistance system of a motor vehicle
Technical Field
The invention relates to a device and a method for checking sensors for at least one driver assistance system of a motor vehicle during an assembly process of the motor vehicle carried out by means of an assembly hanger.
Background
Driver assistance systems are used in motor vehicles in order to support the motor vehicle driver or to relieve the motor vehicle driver of the load in certain driving situations. Such driver assistance systems are currently used in motor vehicles in various embodiments, for example as lane keeping assistance systems, parking assistance systems, emergency braking assistance systems, passing assistance systems, distance assistance systems or steering assistance systems. The driver assistance system uses different sensors for detecting the environment of the motor vehicle, in particular ultrasonic sensors, infrared sensors, optical sensors or radar sensors. In order for the driver assistance system to work fault-free and functional, the driver assistance system and thus also the associated sensors must be oriented very precisely in the vehicle. Due to deviations or tolerances occurring during the assembly of the motor vehicle when mounting the motor vehicle components, it is necessary to check the mounting position of the sensor in the final phase of the assembly process, in particular also with respect to the axis of symmetry of the chassis of the motor vehicle.
For this purpose, DE 10 2006 006 023 A1 discloses a device for checking and adjusting a driver assistance system of a motor vehicle. During the production of the motor vehicle, the sensors of the driver assistance system are measured at the belt end with the motor vehicle fastened at the mounting bracket.
DE 10 2015 012 246 A1 describes a method for determining the mounting orientation of a radar sensor of a motor vehicle, with which a highly accurate on-line determination of the mounting orientation is achieved in terms of elevation and azimuth of any radar sensor arranged in the motor vehicle.
Furthermore, DE 10 2004 056 400 A1 discloses a method for offset detection of a distance sensor arranged in a vehicle during assembly of the vehicle, wherein electromagnetic radiation is emitted by the distance sensor in a measuring device and the reflected radiation is detected and evaluated.
Finally, DE 10 2008 057 652 A1 discloses a method for calibrating a sensor of a vehicle, wherein the calibration is carried out as a function of at least one reference point during the assembly of the vehicle while the vehicle is moving on a conveyor belt.
Disclosure of Invention
The invention is based on the following tasks: starting from this known prior art, the inspection of the sensor system for at least one driver assistance system of the motor vehicle is carried out in a simple manner during the assembly process of the motor vehicle.
According to the invention, this object is achieved by a device for checking sensors for at least one driver assistance system of a motor vehicle during an assembly process of the motor vehicle carried out by means of an assembly hanger.
The object is also achieved by a method for checking sensors of at least one driver assistance system of a motor vehicle during an assembly process of the motor vehicle carried out by means of an assembly hanger.
An advantageous embodiment of the device according to the invention is an integral part of the invention.
The device according to the invention comprises a calibration device for calibrating the sensors of at least one driver assistance system for the motor vehicle and a housing of a lifting device by means of which the motor vehicle on the wheels is lowered or lowered vertically from the mounting bracket in the stationary state of the motor vehicle onto a transport level arranged lower.
The calibration device is arranged at the housing of the lifting device; preferably, the calibration device is arranged at or connected to a lift basket (Hubkorb) which receives the motor vehicle during the lowering process of the motor vehicle, in particular the calibration device is fixed to the lift basket housing by means of at least one profile.
In order to prevent a motor vehicle which is already on the wheels at the point in time of the lowering process from moving itself during the lowering process, i.e. in order to prevent undesired translational movements of the motor vehicle even though the motor vehicle is actually stationary during the lowering process, and thus in order to ensure a trouble-free manner of action of the calibration device during the lowering process, the lifting device and preferably the lifting basket of the lifting device have a correction device by means of which a one-to-one positioning of the respective motor vehicle in the lifting basket and thus in the lifting device can be achieved and the motor vehicle is fastened in the lifting device or in the lifting basket of the lifting device during the lowering process.
In particular, the correction device can also be adjusted individually for different vehicles transported on the mounting bracket, whereby a constant positioning of the vehicle in the lifting basket and thus in the lifting device is also achieved for different vehicle types or vehicle models.
The correction device comprises, for example, a guide rail at the lifting basket, which cooperates with a corresponding guide at the mounting cradle. This is achieved by: the motor vehicle is centrally received in the lifting basket and thus in the lifting device and remains positioned there even during the lowering process, so that the motor vehicle can be lowered in a defined position onto a lower conveying level.
In order to calibrate the sensor provided in the motor vehicle for the at least one driver assistance system, the calibration device has at least one Doppler generator, by means of which the sensor associated with the Doppler generator is calibrated during the lowering process of the motor vehicle. That is to say, the calibration takes place during the period of time during which the motor vehicle is transported vertically from the assembly level to the transport level or the floor level, whereas the motor vehicle itself cannot move in this case.
Preferably, each sensor for a driver assistance system provided in the motor vehicle is associated with such a doppler generator in the calibration device. All such sensors can thus be calibrated simultaneously and thus time-efficiently during the lowering process of the motor vehicle.
The doppler of the calibration device preferably takes place at different locations at the lifting basket of the lifting device and thus at the housing of the lifting device, and is in this case in particular also fixed at the housing of the lifting device and in particular at the housing of the lifting basket, respectively, via a profile, for example via an aluminum profile.
In order to carry out the calibration process and thus to accurately adjust or orient the doppler generator for the associated sensor of the driver assistance system, the doppler generator of the calibration device is adjustably mounted at the housing of the lifting device and in particular at the housing of the lifting basket of the lifting device.
This adjustment of the doppler generator can be performed mechanically by means of an adjustment mechanism or can be performed electronically by means of adjustment electronics.
The calibration process for calibrating the sensor is initiated here via the controller or the diagnostic device. The calibration process starts as soon as the lowering process of the motor vehicle in the vertical direction starts or as soon as the motor vehicle is transferred from the mounting cradle into the lifting device or into the lifting basket of the lifting device.
The sensor of the driver assistance system to be calibrated during the lowering process of the motor vehicle can be configured and positioned at the motor vehicle at will. Preferably, however, the radar sensor and in particular the nanoradar sensor of the motor vehicle are thereby calibrated during the lowering process of the motor vehicle. These radar sensors and in particular nanoradar sensors of a motor vehicle are arranged, for example, at all four corners of the motor vehicle.
Advantageously, with the device according to the invention and the method according to the invention, the calibration of the sensor for the at least one driver assistance system of the motor vehicle is achieved in a simple manner and time-efficient without additional measuring stations or separate measuring devices, since the calibration process is integrated into the flow of the assembly process of the motor vehicle without requiring costly additional process steps with corresponding space requirements in the assembly area.

fig. 2 shows a schematic diagram of the lifting device in a side view;
FIG. 3 illustrates a schematic view of a lifting basket of the lifting apparatus in a front view;

Detailed Description
In the figures, identical or functionally identical elements are provided with the same reference signs.
The lifting device 10, which is shown in front view in fig. 1 and in schematic side view in fig. 2, is set up at the end of the assembly process in the assembly area of the motor vehicle 20 in order to lower the motor vehicle 20, which is suspended at the assembly hanger 30 and has been provided with wheels 21, from the upper assembly level 31 to the lower bottom region, which is the transport level 32, where the motor vehicle 20 is lowered onto the rubber belt 33 mounted there, with which the motor vehicle 20 is automatically transported to the final acceptance of the motor vehicle 20.
In the case of a lowering process, the mounting bracket 30 is first fed into the lifting device 10 together with the motor vehicle 20 suspended at the mounting bracket and resting on the wheels 21. The mounting bracket 30 is stopped at a specific position in the lifting apparatus 10 (see left half of fig. 1, upper motor vehicle 20), and then from this position, the type recognition is performed on the motor vehicle 20 located in the lifting apparatus 10. The lifting basket 11 of the lifting device 10 is then adjusted accordingly to the identified wheelbase of the motor vehicle 20, i.e. as a function of the vehicle model of the motor vehicle 20.
The motor vehicle 20 is displaced from the mounting bracket 30 into the lifting basket 11 (see right half of fig. 1, upper motor vehicle 20) and is centered in the lifting basket 11 of the lifting device 10 by means of the correction device 13 and fastened in the lifting basket 11, while the mounting bracket 30 is transported further and thus leaves the area of the lifting device 10. Since there is now already a sufficient degree of freedom of movement, a lowering process for the motor vehicle 20 can now also be performed in that the lifting basket 11 of the lifting device 10 is transported vertically downwards together with the motor vehicle 20 located therein by means of the electric drive.
Typically, such a vertical lowering process of the motor vehicle 20 is performed during a duration of 10 seconds to 15 seconds.
During this duration, which is typically 10 to 15 seconds, a sensor provided in the motor vehicle 20 for at least one specific driver assistance system is calibrated for the purpose of displacing the motor vehicle 20 from the mounting suspension 30 or for the purpose of lowering the motor vehicle 20 in the lifting basket 11 of the lifting device 10 from the mounting level 31 onto the transport level 32. For example, the nanoradar sensors of lane change traffic auxiliary driver assistance systems for avoiding accidents when changing lanes are calibrated, wherein the regions alongside and in front of the motor vehicle 20 itself are monitored for the presence of critical objects on the driver side and on the co-driver side, and/or the nanoradar sensors of the front cross traffic auxiliary driver assistance system for alerting the driver of the motor vehicle 20 to crossing traffic when stationary or when scrolling forward (intersection, exit) are calibrated.
As is schematically shown in front view in fig. 3 and in side view in fig. 4, the calibration device 40 is preferably arranged for this purpose at the lifting basket 11 of the lifting device 10. For example, the calibration device 40 is adjustably mounted on the outer side of the housing 12 of the lifting basket 11 at the housing 12 of the lifting basket 11 by means of an aluminum profile 42 which is preferably provided for reasons of lightweight construction. If possible, other fastening devices for the calibration device 40 or other fastening variants for the calibration device 40 can also be provided for different model variants of the motor vehicle 20, in particular also for the following cases: the installation position of the sensor 22 and thus the angular orientation of the calibration device 40 to be provided for calibrating the sensor 22 should be such that this is required.
An apparatus for checking the sensor 22 of at least one driver assistance system for the motor vehicle 20, in particular during an assembly process of the motor vehicle 20 which is carried out by means of the assembly hanger 30, is thus formed. The device has in particular at least a housing 12 of the lifting device 10. With this lifting device 10, the motor vehicle 20 on the wheels 21 can be moved vertically during the lowering process from the mounting cradle 30 onto the transport level 32 arranged lower. The device also has at least a calibration means 40 for calibrating the sensor 22. The calibration device 40 is arranged at the housing 12 of the lifting apparatus 10.
According to fig. 5, the motor vehicle 20 has a sensor 22 in the form of a nanoradar sensor at each corner 23 (front right, front left, rear right, rear left) of the motor vehicle 20, so that a total of four nanoradar sensors are provided for detecting different environmental areas of the motor vehicle 20. The nanoradar sensors are arranged here in the front (at the front side of the motor vehicle 20) and in the rear (at the rear side of the motor vehicle 20) in specific mounting positions and at specific mounting angles in the region of the bumper of the motor vehicle 20, depending on the respectively present vehicle model. On the front side of the motor vehicle 20, the nanoradar sensor is mounted, for example, at an angle of about 65 ° with respect to the axis of symmetry of the vehicle, and on the rear side of the motor vehicle 20, the nanoradar sensor is mounted, for example, at an angle of about 45 ° with respect to the axis of symmetry of the vehicle.
The calibration device 40 preferably has a doppler generator 41 for each sensor 22 to be calibrated. For example, four doppler generators 41 are thus provided in the calibration device 40. These doppler generators 41 of the calibration device 40 are adjusted for the installation angle of the respectively associated sensor 22 in that the doppler generators 41 are adjusted electrically or mechanically at the housing 12 of the lifting basket 11 or at the aluminum profile 42 on the outside of the housing 12 of the lifting basket 11.
For example, all four sensors 22 can be calibrated simultaneously, for example within 10 seconds, by means of the calibration device 40, in that after the type recognition of the motor vehicle 20 located in the lifting basket 11 of the lifting device 10 at the position determined by the calibration device 13, the calibration device 40 is activated by means of the controller or the diagnostic device and the calibration process is started accordingly.
In the case of a calibration procedure, in particular each of the doppler generators 41 preferably simulates an object moving at a constant speed. These moving simulated objects are identified by the sensors 22 and in particular also distinguished from stationary objects, wherein each sensor 22 identifies the simulated object of its associated doppler generator 41.
The position data, i.e. the coordinates of the doppler generator 41 relative to the axle of the motor vehicle 20, are measured. The error position (offset position) of the sensor 22 measured based on the difference between the set position and the measured position is corrected. To correct the error position and thus to calibrate the sensor 22, the angle of the sensor 22 about the vertical axis 24 (z-axis) of the motor vehicle 20 is recalibrated, i.e. the yaw angle of the sensor 22 is adjusted accordingly.
