Description

The present invention relates to a control device for a motor vehicle and a motor vehicle with such a control device. It also relates to a method for operating a motor vehicle in a parking lot.

Autonomously or semi-autonomously driving motor vehicles are known. Corresponding functions can also be used to park or park a motor vehicle. In this context, it is essential that the motor vehicle has sensors to detect its position in relation to other objects and in particular other motor vehicles. the DE 10 2015 004 923 A1 describes a method for self-localization of a vehicle. The motor vehicle can, for example, automatically drive to a gas station or washing station and also to a loading and/or unloading area. With regard to the initial situation, the loading or unloading place is a separate place outside of the previous standing or parking space of the motor vehicle.

the DE 10 2012 200 625 A1 describes a method for executing a parking process for a motor vehicle using a remote control, the remote control merely causing the parking process to be carried out automatically, but not navigating the vehicle to the target position using the remote control.

The many possible uses of self-driving, autonomous, semi-autonomous or assisted vehicles have not yet been fully exploited. Remote control of motor vehicles also has a wide range of possible applications.

It is an object of the invention to meaningfully expand the possibilities.

The object is achieved by a control device for a motor vehicle, a motor vehicle with such a control device, and a method for operating a motor vehicle in a parking lot.

The control device according to the invention is designed, starting from a parking situation of the motor vehicle parked in a parking space, to assume a predetermined mode in which this control device enables or actively causes the parking situation in the parking space to be changed to a limited extent, with a change of position, by a predetermined Purpose of use of the motor vehicle, in particular getting out of occupants, getting in of occupants, unloading a cargo space of the motor vehicle and/or loading a cargo space of the motor vehicle, before or after the change in the parking situation.

The invention takes account of the fact that it is often difficult to unload or load the motor vehicle or to get in and out of the motor vehicle in tight parking spaces and in parking lots. The parking situation can also be changed several times in the same parking lot, for example first to get out and then to unload or vice versa, first to load and then to get in.

Here, the parking lot is understood to mean any type of possible parking space for a motor vehicle, it being irrelevant whether the parking space is specifically delimited by white stripes and the like, or whether the motor vehicle is simply stationary. The parking situation refers to the specific position of the motor vehicle in the parking lot (for example: at a distance of 15 cm from a wall or the like). The change in the parking situation in the parking lot to only a limited extent means that the assignment of the motor vehicle to a specific parking lot does not change. The parking space is therefore not changed in a parking facility with a plurality of parking spaces, but rather the motor vehicle only moves with respect to the existing parking space. This can be determined, among other things, by whether another motor vehicle is allowed to drive into this parking space or not. The parking lot will be left if another motor vehicle is able to. On the other hand, the parking situation in the parking lot is only changed if the motor vehicle is positioned slightly differently (in the above example: instead of 15 cm at a distance of 50 cm from the wall).

The invention also provides a motor vehicle with the control device.

In one embodiment, the motor vehicle includes a device for detecting obstacles in the vicinity of the motor vehicle when realizing the purpose of use, the control device requesting detection data from the device for detection in the predetermined mode and the limited extent of the change in the parking situation depends on the detection data definitely. For example, in the predetermined mode, the parking situation is changed in such a way that the purpose of loading the motor vehicle is made possible if other motor vehicles in the original parking situation make loading the motor vehicle difficult or even impede it.

The motor vehicle can, according to another embodiment, with a device for Be equipped to receive control commands by an external device, wherein the predetermined mode is assumed in the control device on the basis of a control command from the external device. For example, a smartphone can be used as an external device, which uses an app to cause the motor vehicle to partially park out of a parking space. In one exemplary embodiment, the contactless vehicle key is also used to issue such a control command. In these cases, the user may be responsible for detecting obstacles.

The method for operating a motor vehicle of the type according to the invention in a parking lot includes that the motor vehicle changes a parking situation in the parking lot under a predetermined condition by changing position in order to achieve a predetermined purpose of use of the motor vehicle, in particular getting out of occupants, getting in of occupants, unloading a cargo space of the To realize motor vehicle and / or loading a loading space of the motor vehicle before or after changing the parking situation.

The advantages of the control device according to the invention and the motor vehicle according to the invention also apply to the method according to the invention.

In one embodiment, the predetermined condition includes that the motor vehicle receives control commands from an external device and, controlled by the external device, its control unit adopts the predetermined mode and uses the control commands to change position. In another exemplary embodiment, the predetermined condition includes that the predetermined mode is assumed by a trigger command and the motor vehicle then automatically changes position. In one case, the motor vehicle is thus remotely controlled in sections in the parking lot, in the other exemplary embodiment it drives autonomously or at least with assistance. In one exemplary embodiment, it can also be provided that the motor vehicle detects an approaching external device (smartphone, vehicle key or the like) and then issues the trigger command itself at a certain minimum distance (or possibly a certain signal strength) to adopt the predetermined mode. This applies both in connection with a remote control and in particular with a position change subsequently caused automatically by the vehicle.

In an exemplary embodiment of the method, the predetermined condition and/or an extent of the change in position is defined as a function of a location of the parking space. For example, a vehicle driver can specify that the position change does not have to take place in his garage at home, since he has access to the trunk anyway, but in a parking lot of a frequently visited supermarket and the like. Likewise, the extent of the change of position can also be defined, suitable for such locations: In front of the garage at home, it may be possible to let the motor vehicle protrude far out of the garage for loading and unloading, whereas it may be in a supermarket parking lot due to a lack of space, it does not extend quite as far to be loaded or the like.

In one embodiment of the method, the motor vehicle and/or an external device (smartphone or device coupled to the smartphone via the cloud, such as a personal computer, tablet, etc.) is configured in advance as to which predetermined condition should apply and/or the extent of the change in position should apply and/or which purpose of use should be achieved. In particular, combinations of predetermined condition and extent and/or purpose of use can be configured.

In general, the possibilities offered by modern smartphones can be exploited, such as self-learning. The configuration can thus take place implicitly. For example, when a smartphone approaches, the motor vehicle can send a message to the smartphone to ask whether the purpose of use should be achieved ("Should the vehicle be driven out for unloading?"), and only if the response is positive is the trigger command for the sent out automatically or the further process (remote control and the like) allows. This self-learning can be user-specific and/or site-specific. Ideally, the information is then available in the motor vehicle that a specific user prefers one purpose ("unloading"), while another user at the same location uses another purpose ("boarding").

Further features of the invention can result from the following description of the figures and from the drawing. The features and feature combinations mentioned above in the description and the features and feature combinations shown below in the description of the figures and/or in the figures alone can be used not only in the combination specified in each case, but also in other combinations or on their own, without going beyond the scope of the invention to leave.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

The method is described below with reference to a step-by-step parking of a motor vehicle from a parking space. The method can also take place exactly the other way around: the driver of the vehicle cannot park the vehicle completely when the vehicle is being actively controlled, and then he can move up to the parking space.

According to the top view 1A 1 shows a motor vehicle, designated as a whole by 1, which is standing in a parking lot 100 between two other motor vehicles 2 and 3. the 1B illustrates this in perspective. How out 1B As can be seen, the motor vehicle 1 cannot easily be loaded or unloaded because access to the trunk is made more difficult, in particular by the other motor vehicles 2 and 3.

For this purpose, the motor vehicle, as in 2A shown to be moved a small distance ΔP1 without leaving the parking lot 100 completely. In this case, a trunk 4 (see 2 B) open the motor vehicle and loaded lighter than in accordance with the situation 1A /1B. The trunk can also optionally also be opened automatically as part of the method.

In the situation 3A the motor vehicle should be moved a total distance of ΔP2 so that a driver's door 5 or a rear door 6 can be opened easily without damaging the other motor vehicles 2 and 3. The opening can be done by a person himself, unless this is also part of the procedure.

This in 4 Motor vehicle 1 shown has a central control device 10 for the purpose of carrying out the method, which is equipped with at least one ultrasonic sensor 12, an optical camera 14, an infrared camera 16 or other similar devices for acquiring information about the immediate surroundings of the motor vehicle. (An inductive device that detects the presence of another motor vehicle made of sheet steel is also conceivable.)

The control device 10 controls the motor M of the motor vehicle and, if necessary, also the steering L, in order to move the motor vehicle in the parking lot by the distances ΔP1 or ΔP2, if necessary also in total, in order to cause the motor vehicle 1 to drive automatically on normal roads (autonomous driving and the like).

The motor vehicle 1 also optionally has a device 18 for wirelessly detecting a vehicle key 20 that a person is carrying, or for detecting a smartphone 22 that this or another person is carrying, with the key 20 being pressed by pressing Commands given to actuators and/or commands given in a program (app) running on the smartphone 22 are transmitted. For example, when the person carrying the key 20 approaches, the control device 10 can begin to detect the surroundings of the motor vehicle 1 by means of the units 12, 14 and 16 and adopt the mode in which the parking space is gradually exited. When operated with the smartphone 22, it can be provided that first a reinsurance takes place as to whether and what type of parking space (for loading according to 2A /2B or for boarding according to 3A /3B) is desired. It is also possible for several smartphones (not shown in the figure) to be coupled at the same time so that the motor vehicle 1 matches the before moves out of the preferred seating position of these people in the parking lot 10 by the distance ΔP1, ΔP2 or another distance. The smartphone 22 can also be used for active remote control, provided that the control device 10 is still designed to take the specific parking mode. As an alternative to using the ultrasonic sensor 12, the optical camera 14, the infrared camera 16 or the like, the user can then be responsible for capturing the environment if he is within sight.

The motor vehicle 1 can also have a positioning system 24 (GPS system, normally intended for navigation) and the control device can take into account the location of the motor vehicle, for example in order to determine conditions under which the situations according to 2A /2B and 3A/3B and/or what extent ΔP1, ΔP2 should apply at a specific location.

While preceding the situations according to 1A /1B, 2A/2B and 3A/3B are described as being taken successively may also differ from the situation of 1A /1B straight to the situation 3A /3B or according to the situation 2A / 2B the mode can be left immediately, so that the vehicle driver (who then nevertheless got in) can actively drive the motor vehicle out of the parking space 100 completely. The order can also be reversed, for example the vehicle driver can first move the motor vehicle according to the situation 3A / 3B spend, get out and the vehicle 1 then automatically in accordance with the situation 2A / 2B or 1A/1B to unload the motor vehicle or to move away from the motor vehicle 1 that is completely parked in the parking lot 100 .

Furthermore show 5A / 5B the motor vehicle 1 than parked backwards in the parking lot 100, this in front of a wall 200 such as in a multi-storey car park. Here the wall 200 blocks access to the trunk. Therefore, the motor vehicle 1 drives according to FIG 6A /6B a fair bit further forward than in the previous examples to allow for loading. However, the assignment to the parking space 100 is still clearly given, because no other motor vehicle can park here either, the parking space 100 is still occupied. In this example, all occupants in the situation as appropriate 6A /6B board immediately, so that no second exit stage is necessary. However, the latter can be the case if - as in the case of a minibus - loading takes place via a side door located more at the front.
