Description

The invention relates to a method for detecting a parking area for a vehicle according to the preamble of claim 1.

From the DE 10 2011 118 726 A1 For example, a method for detecting a parking space for a motor vehicle by means of a parking assistance system of the motor vehicle and such a parking assistance system are known. The method comprises the following steps: Determining a geometric parameter of the parking space based on sensor data of a sensor device of the parking aid system and detecting other, different from the sensor data environment information of the motor vehicle by means of the parking aid system and detecting the parking space on the basis of the geometric parameter of the parking space and thereby taking into account the other environmental information. The consideration of the further environmental information includes that the geometric parameter of the parking space is also determined as a function of the further environmental information of the motor vehicle.

The invention is based on the object to provide a comparison with the prior art improved method for detecting a parking area for a vehicle.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

In the method for detecting a parking area for a vehicle, the vehicle comprises at least one environment detection unit for detecting a vehicle environment and detecting a free space located in the vehicle environment. According to the invention, upon detection of at least one free space, a number of information relating to the free space is determined, wherein the determined information relating to the free space is compared with information stored in the vehicle relating to traffic regulation rules, and wherein upon determination of information about a subarea of the detected free space that indicates a breach against at least one traffic regulation rule, the detected partial area of the free space is differentiated from an allowed parking area in another partial area of the free space and is detected as an unauthorized free space for parking.

For example, the vehicle is a partially autonomously or autonomously operable vehicle with at least one driver assistance system, in particular a parking assistance system, to assist a driver when parking the vehicle. Furthermore, the vehicle comprises at least one output unit for optically and / or acoustically outputting information about at least one parking area permissible and / or impermissible part of a free space to the driver and / or a vehicle user.

In particular, the method for avoiding unauthorized parking is provided for in certain parking areas which are generally suitable, but which are to be kept legally free, such as entrances and exits and / or driveways. For example, by means of the method according to the invention, a systematic analysis of information relating to the consideration of a free space, in particular that indicating a traffic regulation rule, is carried out automatically by the vehicle.

For example, land entrances, land exits and / or Feuerwehrzufahrten and / or other designated as a no-stop and / or parking ban traffic clearances are to be kept. Furthermore, the driver is supported in order to be able to better distinguish between a parking area comprising a stop and / or no parking area of a free space from a permitted parking area. For example, level crossings, for parking and / or holding inadmissible road and / or lane areas, stops for public transport, disabled parking spaces and / or other open spaces, for example, as for parking and / or holding unauthorized areas are difficult to recognize. For example, due to a so-called sign forest in some traffic areas traffic signs and / or markings that indicate a traffic regulation rule, for example, bad for a vehicle user visible and recognizable. In addition, visually easily overlooked curb subsidence and / or curb markings can be detected in a simple manner.

In the case of detection of the parking area of the free space which is not permitted for parking, this information is output to the driver by means of the output unit for the purpose of being aware of the unauthorized parking possibility. If the vehicle is operated autonomously, the vehicle continues to search for an admissible parking space upon detection of the parking area of the free space which is not permitted for parking, and / or initiates parking in the partial area of the free space detected as parking area permitted for parking. In this case, detection of a parking area and the differentiation of partial areas of a free space are improved by means of the method according to the invention.

Embodiments of the invention will be explained in more detail below with reference to a drawing.

Showing:

1 schematically a vehicle with a device for detecting a parking area, wherein the vehicle is in a free space with a number of different sub-areas.

The only 1 shows a vehicle 1 with a device 2 for detecting a parking area P. The vehicle 1 is in a partial area T1 of the vehicle 1 detected free space F. In particular, the sub-area T1 is a parking allowable portion T1 of the free space F.

For example, the free space F comprises a number of subregions T1 to T3, wherein in the exemplary embodiment shown, three visible subregions T1 to T3 are respectively shown. Here, the partial areas T1 to T3 are indicated by dashed lines.

In particular, the free space F comprises two subregions T2, T3, which include an entry and exit of a property, such as a garage entrance and exit. Alternatively or additionally, one of the two subregions T2, T3 is, for example, an access road, such as, for example, a fire brigade access road. The partial area T1 of the free space F comprises, in particular, a parking space for a vehicle 1 permissible parking area P.

The vehicle 1 is, for example, a partially autonomous or autonomously operable vehicle 1 , which in autonomous operation can hold or change a lane without the influence of a driver, driving, steering and parking independently. In semi-autonomous operation of the vehicle 1 becomes the driver of the vehicle 1 supported by a number of driver assistance systems at different driving tasks. For example, the device 2 Such a driver assistance system, in particular a parking assistance system and / or parking and parking assistance system.

The device 2 is to assist the driver in a search for a parking facility and, for example, to assist in an entry and / or Ausparkvorgang the vehicle 1 intended. For example, the driver when parking side or parallel parking, reverse and / or Vorwärt- parking the vehicle 1 supported. In particular, the device 2 intended to carry out a partially or fully autonomous parking operation.

Furthermore, the device comprises 2 at least one environment detection unit 3 for detecting a vehicle environment and detecting the free space F in the vehicle environment. For example, the environment detection unit 3 an image capture unit comprising at least one mono or stereo camera. Alternatively or additionally, the environment detection unit comprises 3 a 360 ° camera, for example, a so-called surround view system of the vehicle 1 , Furthermore, the environment detection unit 3 For example, include a number or plurality of lidar and / or radar sensor units and / or ultrasonic sensor units. For example, the environment detection unit 3 in and / or on a windscreen area of the vehicle 1 arranged. A detection area of the environment detection unit 3 is indicated in the illustrated embodiment with dashed lines.

For detecting a parking area P for the vehicle 1 When the free space F is detected, a number of information relating to the free space F is determined, with the information determined being present in the vehicle 1 deposited information on traffic regulation rules.

For example, the environment detection unit 3 at least one evaluation unit 4 have for the evaluation of the determined information and / or at least with such, in the vehicle 1 arranged evaluation 4 be coupled. In the evaluation unit 4 For example, the deposited information on the traffic regulations, in particular the Highway Code (StVO), deposited, ie stored.

In one possible embodiment, the evaluation unit 4 For example, from a central and / or external data processing unit, such as a so-called back-end server or a so-called cloud, transmitted data on traffic rules.

When ascertaining at least one piece of information that indicates a violation of at least one traffic regulation rule, such as a rule of a holding or parking ban, at least one of the detected partial areas T2, T3 of an allowed parking area P, such as in the sub-area T1, distinguished. In this case, the partial area T2 and / or the partial area T3 are detected as a partial area T2, T3 of the free space F that is not permitted for parking.

For example, in order to determine the information about the acquired subregions T2, T3, wherein the information indicates a violation of at least one traffic regulation rule, at least one traffic sign characterizing a stopping and / or parking prohibition is used 5 and / or distinctive mark detected. The traffic sign 5 For example, is a conventional no-parking or no-parking sign, a sign with a caption "freeway entrance / exit" and / or with a tow icon. For example, also traffic signs 5 , which refer to a stop of a public transport, detected and evaluated as an invalid parking area.

Furthermore, a curb lowering 6 and / or a curb marking, comprising a color and / or pattern marking of a curb and / or a surface on a traffic route, by means of the environment detection unit 3 be detected automatically.

In a further development, at least one installation on and / or on a property boundary, such as, for example, a property fence and / or an entrance, exit and / or access gate, is detected to determine information indicating a violation of at least one traffic regulation rule , Furthermore, a traffic sign characterizing a disabled parking space becomes or becomes 5 and / or a marked a disabled parking space marking and / or a level crossing detected. In addition, for parking and / or holding inadmissible road and / or lane areas, such as at an intersection and / or in a one-way street and / or due to a no-parking or no parking mark detected.

In one embodiment, position data of the subregions T2, T3 respectively detected in the unauthorized parking area P1 in the vehicle 1 in particular in a map service of the vehicle 1 , deposited.
