Definitions
- the invention relates to a device and a method for determining a position of a vehicle relative to a charging module.
- the aim is to position the vehicle as precisely as possible above a charging coil in the ground in order to achieve a good magnetic coupling between a coil in the vehicle and the charging coil, since the two coils are so precise for the highest possible efficiency must be positioned to each other as possible. Positioning by means of is known
- Magnetic pulses from the vehicle and amplitude and phase detection on the side of the charging coil in the floor are strongly influenced by the respective environmental conditions, for example reinforcements in the floor, garage doors, material of the vehicle chassis.
- the respective environmental conditions for example reinforcements in the floor, garage doors, material of the vehicle chassis.

- Rear axle steering of the motor vehicle can be actuated automatically by means of an electronic computing device in order to position the motor vehicle relative to the charging device, with the steps:
- the invention is based on the object of specifying an improved device and an improved method for determining a position of a vehicle relative to a charging module arranged in the vicinity of the motor vehicle.
- Data processing unit is provided in the vehicle, which is designed to assign detected reflected light beams to the respective radiating digital headlights with the respective angle and, when detecting reflected light beams of both digital headlights with a respective angle, a distance of the vehicle from the charging module in the direction of a longitudinal axis of the vehicle and an offset in Trigonometric determination of the transverse direction to the longitudinal axis on the basis of the recorded angles and the distance between the digital headlights.
- a charging module arranged in the vicinity of the vehicle, with a charging coil, the vehicle comprising a camera system, and a digital headlight system having a left digital headlight and a right digital headlight which are spaced apart from each other by a distance, each of the two digital headlights is driven in order to project digital light beams by scanning at different angles, such that only one of the digital ones at any time
- Headlights emit a light beam at a specific angle
- the camera system detecting a light beam of the light beam reflected by a reflector arranged in the zero point of the charging coil of the charging module, with detected reflected light beams being assigned to the respective emitting digital headlight with the respective angle and upon detection of reflected light beams
- Both digital headlights with a respective angle show a distance between the vehicle and the charging module in the direction of a longitudinal axis of the vehicle and an offset in
- Transverse direction to the longitudinal axis is determined trigonometrically on the basis of the detected angle and the distance between the digital headlights.
- an exact position determination of the vehicle relative to the charging module is possible by means of a camera system which may already be present, the exact position of the camera system in the vehicle
- the digital headlight system can also already be provided in the vehicle. Additional sensors may not be necessary. In contrast to magnetic methods for position determination, the dependence on ambient conditions is reduced and less susceptible to faults. In contrast to camera-based systems in the underbody, there is less risk of contamination.
- the detection of the reflected light and the assignment to the respective radiating digital headlight with the associated beam angle is also much more robust than detection of the charging module by means of image evaluation. With the exception of the reflector arranged on the charging module, the position sensor system is located exclusively on the vehicle, so that interoperability with different charging modules is possible.

- Headlights 4, 5 projected light rays 6 can be reflected back in the direction of the vehicle 1.
- each of the digital headlights 4, 5 scans the surrounding area, that is to say projects light beams 6 at different angles.
- the left digital headlight 4 and the right digital headlight 5 can be activated alternately, for example, so that only one of the digital headlights 4, 5 emits a light beam 6 at a certain angle at any time.
- the scanning can be activated by the driver.
- the scanning can be carried out continuously in the background in order to recognize a charging module 2 in the vicinity.
- the digital headlights 4, 5 can be designed to emit light beams 6 with a specific characteristic, for example wavelength, and the optical sensor 3 can be designed to receive light beams 6 with this characteristic and filter out light beams with a different characteristic in order to avoid false detections.
- Figure 2 is a schematic view of the vehicle 1 and the charging module 2, wherein only the right digital headlight 5 emits a light beam 6 at a certain angle a to a connecting line between the right digital headlight 5 and the left digital headlight 4.

- the angle a of the light beam 6 at this time is in one
- Control unit of the vehicle 1 known.
- Figure 3 is a schematic view of the vehicle 1 and the charging module 2, wherein only the left digital headlight 4 emits a light beam 6 at a certain angle ⁇ to the connecting line between the right digital headlight 5 and the left digital headlight 4.
- the light beam 6 strikes the reflector 7 and is directed in the direction of the vehicle 1 is reflected as a light beam 6 ', where it is received by the optical sensor 3.
- the angle ⁇ of the light beam 6 at this time is known in a control unit of the vehicle 1.
- FIG. 4 is a schematic view of the geometrical relationships of the vehicle 1 and the charging module 2 in a first case.

- FIG. 6 is a schematic view of the geometrical relationships of the vehicle 1 and the charging module 2 in a third case.
- the angle a is greater than or equal to 90 ° and the angle ⁇ is greater than 0 and less than 90 °.
- the vertical x on the extension of the distance c runs through the reflector 7.
- the relative position of the vehicle 1 to the charging module 2 can thus be determined.
- the driver can provide support based on the determined relative position
- Driving instructions are given or the vehicle 1 is automatically positioned on the basis of the determined relative position, so that the charging coil of the charging module 2 is oriented as optimally as possible to the coil of the vehicle 1 for magnetic coupling.
- the position of the vehicle 1 relative to the charging module 2 can be tracked as long as the reflector 7 is in the field of view of the optical sensor 3. If the vehicle 1 is moving outside the field of view of the optical sensor 3, the
- Driver support or automatic positioning for the remaining distance are carried out via odometry data.
- the light emitted by the digital headlights 4, 5 for the triangulation can differ from the normal light emission of the digital headlights 4, 5 both in intensity and in color / wavelength and can be used alone or together, that is, superimposed with the normal one Light function take place.
- the digital headlights 4, 5 can be activated in succession. For example, first an arc is illuminated by the left digital headlight 4 and then an arc by the right digital headlight 5 or vice versa. Alternatively, the light alternates between the digital ones
- Headlights 4, 5 emitted, with a short time interval between two beams can be provided without light emission to distinguish the from
- Reflector 7 to improve reflected light beams of the two digital headlights 4, 5 through the optical sensor 3.
- the optical sensor 3 can determine, depending on the reflected light frequency, from which of the two digital headlights 4, 5 the light was emitted.
- scanning by both digital headlights 4, 5 is also possible at the same time.
- time offset and different color / wavelength can be used together to ensure that the reflection can be assigned to the left or right digital headlights 4, 5.
- each digital headlight 4, 5 can be emitted simply in a complete circular arc and thus the whole with each pass
- Illuminate the surrounding area or the system always starts at the innermost or outermost angle and stops scanning the circular arc as soon as the sensor has detected the corresponding reflection and thus further scanning of the remaining circular arc would be unnecessary. This saves both scanning time and energy, since the entire circular arc does not always have to be illuminated. The shorter sampling time per arc would then also make it possible to increase the repetition rates of the scans of the arcs and thus increase the accuracy, since it is often possible to determine a relative position of the vehicle in relation to the loading plate.
- the reflector 7 can be arranged in a zero point of the coil of the charging module 2. Alternatively, this can also be located at another previously known relative position in relation to the base plate of the charging system. Daimler AG
