Description

[0001] The present invention relates to a parking system for a vehicle. State of the art

[0002] Today's vehicles are equipped with a variety of driver assistance systems to support the driver. These support the driver in a variety of driving situations. One driving situation in which the driver would like assistance is when searching for a parking space and parking in an empty space. Parking assistance systems support the driver when parking in an empty space. The parking assistance system can detect a parking space that the vehicle is driving past as empty and suggest that the driver park in this parking space. After the driver confirms, the vehicle drives fully automatically or semi-automatically from a standstill into the detected parking space. Since the safety requirements for such a fully or semi-automatic parking process are high, the control system in the vehicle requires a large amount of information from the vehicle's surroundings.Due to the high computing effort required to evaluate the surrounding situation, such fully or semi-automated parking operations take place at low speed, usually walking pace. Disclosure of the invention

[0003] The parking system for a vehicle according to the invention allows the driver to be guided to a free parking space at a speed that is comfortable for the driver.

[0004] The parking system has a plurality of sensors and at least one control unit. The sensors are configured to scan the vehicle's surroundings. The control unit is configured to receive and / or retrieve data from the sensors. This enables the control unit to detect the vehicle's surroundings using the sensors. The control unit is configured to receive and / or retrieve an infrastructure map of a parking garage and / or parking area. The infrastructure map indicates the occupancy of the parking spaces. The control unit is configured to detect a plurality of empty parking spaces on the infrastructure map and to define one of the parking spaces as the target parking space. The control unit is configured to determine the vehicle's own position in the parking garage using the sensors and / or to receive and / or retrieve the vehicle's own position in the parking garage from an external unit.The control unit is configured to determine a route from the vehicle's own position to the destination parking space using the infrastructure map. The control unit is configured to output and / or provide the route.

[0005] This eliminates the need for the driver to search for a free parking space independently. Instead, the parking system provides a route. The driver can concentrate on the road layout and traffic conditions. By using the infrastructure map, the control unit can identify empty parking spaces that a driver cannot immediately see from a vehicle, such as a parking space behind a pillar or at the end of a parking row. This makes it easier for the driver to find a parking space and reduces the time required to reach the parking space.

[0006] The subclaims show preferred developments of the invention.

[0007] The parking system preferably has a display. The display is configured to receive and / or retrieve the infrastructure map and a route from the control unit and / or to display the infrastructure map and the route on the infrastructure for a driver of the vehicle. Thus, the driver can use the display to obtain an overview of the empty parking spaces. Furthermore, a graphical representation of the route from the driver's own position to the destination parking space facilitates orientation and guidance for the driver.

[0008] Particularly preferably, the control unit is configured to determine another empty parking space in the vicinity of the vehicle using the sensor data, to set the other empty parking space as the new destination parking space, and to adapt the route to the new destination parking space. Thus, while driving from its own position at the start of route guidance to the destination parking space, the vehicle is able to detect an empty parking space in the vicinity and to suggest it to the driver as the new destination parking space or to set it directly. This shortens the time required to reach an empty parking space.

[0009] Advantageously, the control unit is configured to perform an automated parking process for the vehicle in the destination parking space and to receive and / or request permission from the driver before performing the automated parking process. This allows the driver to decide independently upon reaching the parking space whether they want to park independently or automatically. Automated parking using the parking system relieves the driver of a difficult task in addition to searching for a parking space. Furthermore, the driver does not need to access an additional assistance system, which would require additional time. If the driver were to access a different assistance system for automated parking, the system would first have to obtain an overview of the surroundings and the destination parking space.

[0010] Particularly advantageously, the control unit is configured to detect the target parking space before reaching the target parking space, to request the driver's permission to perform the automated parking process before reaching the target parking space, and to perform the automated parking process in the target parking space while the vehicle is moving. The vehicle is always in motion from the moment the target parking space is detected until the parking process is performed. According to this embodiment, the control unit switches from guiding the vehicle while moving to automated parking. This allows the vehicle to move smoothly without coming to a standstill until it reaches the stop position in the parking space.Such a smooth progression of vehicle movement is perceived by the driver as significantly more pleasant than stopping the vehicle simply to request confirmation from the control unit to carry out the automated parking process.

[0011] Preferably, the control unit is configured to receive and / or retrieve a driver input and to take the driver input into account when selecting the destination parking space. Thus, a driver's request can be adapted when selecting the destination parking space and when selecting the route from the vehicle's own position to the destination parking space.

[0012] Particularly preferably, the control unit is configured to detect the target parking space in the physical environment using the sensors and / or to receive and / or retrieve external information and to detect the target parking space in the physical environment based on the external information. Thus, no additional sensors are required to detect the position of the target parking space. This reduces the manufacturing costs of the parking system. Furthermore, this represents redundant detection of the target parking space in addition to the detection of the target parking space using the route and the infrastructure map.

[0013] Advantageously, the control unit is configured to receive and / or retrieve a distance of the vehicle to a parking garage and / or parking area from the navigation system. Furthermore, the control unit is configured to retrieve and / or receive an infrastructure map of the parking garage and / or parking area if a predefined distance between the vehicle and the parking garage and / or parking area is undershot. In addition, the control unit is configured to detect at least one empty parking space in the parking garage and / or parking area and to inform the driver of the presence of an empty parking space. Thus, the driver does not have to actively request the parking system, but instead receives the above information from the parking system while driving. This enables the driver to display possible empty parking spaces where the driver would not expect them.In addition, this self-paced parking system allows the driver to concentrate on the actual road layout. This increases road safety. Furthermore, it prevents the driver from being overwhelmed by a selection of parking spaces, which would distract their concentration from the traffic.

[0014] Particularly advantageous is the display configuration for both the control unit and navigation system data. This means only one display is needed to show the control unit data and the navigation system data. This eliminates the need for the driver to switch between multiple screens.

[0015] Preferably, the display and the control unit are designed as a single unit. The processing of the sensor data by the control unit and the display on the display are performed on the same processing unit. This reduces the space required and also lowers the manufacturing costs of the parking system.

[0016] The invention further comprises a method for parking space guidance for a vehicle. The method comprises six steps. In a first step, an infrastructure map of a parking garage and / or parking area is received. The infrastructure map indicates the occupancy of the parking spaces in the parking garage and / or parking area. In a second step, empty parking spaces are detected on the infrastructure map. In a third step, an empty parking space is defined as the destination parking space. In a fourth step, the vehicle's own position in the parking garage and / or on the parking area is determined and / or received. In a fifth step, a route from the own position to the destination parking space is determined. In a sixth step, the route is output and / or provided.

[0017] This eliminates the need for the driver to search for a free parking space independently. Instead, the parking system provides a route. The driver can concentrate on the road layout and traffic conditions. Using the infrastructure map, the control unit can identify empty parking spaces that a driver cannot immediately see from a vehicle, such as a parking space behind a pillar or at the end of a parking row. This makes it easier for the driver to find a parking space and reduces the time required to reach the parking space.

[0018] The invention further encompasses a vehicle comprising a parking system according to one of the preceding embodiments. The vehicle has the advantages of the embodiments of the parking system. Short description of the drawings

[0019] Embodiments of the invention are described in detail below with reference to the accompanying drawings. In the drawing: Fig. 1 is a schematic representation of a vehicle with a parking system according to a first embodiment of the invention, Fig. 2 a schematic representation of a parking system according to the first embodiment, and Fig. 3 a schematic representation of a method according to the first embodiment of the invention. Embodiments of the invention

[0020] Fig. 1 shows a schematic representation of a vehicle 1 with a parking system 6 according to a first embodiment of the invention.

[0021] Vehicle 1 houses the parking system 6. A display 5 of the parking system 6 is arranged in the interior of the vehicle 1, clearly visible to the driver. Sensors 3 of the parking system 6 are distributed along the outer skin of the vehicle 1 and allow detection of the surroundings 2 of the vehicle 1.

[0022] Fig. 2 shows a schematic representation of a parking system 6 according to the first embodiment.

[0023] The parking system comprises a plurality of sensors 3 and at least one control unit 4. The sensors 3 are configured to scan the surroundings 2 of the vehicle 1. The control unit 4 is configured to receive and / or retrieve data from the sensors 3. Furthermore, the control unit 4 is configured to receive and / or retrieve an infrastructure map of a parking garage and / or parking area. The infrastructure map indicates the occupancy of the parking spaces.

[0024] The control unit 4 is configured to detect a plurality of empty parking spaces on the infrastructure map and to designate one of the parking spaces as the destination parking space. Additionally, the control unit 4 is configured to determine the vehicle's 1 own position in the parking garage using the sensors 3 and / or to receive and / or retrieve the vehicle's 1 own position in the parking garage from an external unit. The control unit 4 is configured to determine a route from the own position to the destination parking space using the infrastructure map. The control unit 4 is configured to output and / or provide the route.

[0025] This eliminates the need for the driver to search for a free parking space independently. Instead, the parking system 6 provides a route. The driver can concentrate on the road layout and traffic conditions. By using the infrastructure map, the control unit 4 can identify empty parking spaces that a driver cannot immediately see from the vehicle 1, such as a parking space behind a pillar or at the end of a parking row. This makes it easier for the driver to find a parking space and reduces the time required to reach the parking space.

[0026] The parking system 6 has a display 5. The display 5 is configured to receive and / or retrieve the infrastructure map and a route from the control unit 4 and / or to display the infrastructure map and the route on the infrastructure for a driver of the vehicle 1. The driver can thus obtain an overview of the empty parking spaces using the display 5. In addition, a graphical representation of the route from the driver's own position to the destination parking space facilitates orientation and guidance of the driver. In this exemplary embodiment, the display 5 and the control unit 4 are configured as physically separate units. Alternatively, the display 5 and the control unit 4 can be configured as a single unit. In particular, the processing of the data from the sensors by the control unit 4 and the representation on the display 5 take place on the same computing unit.

[0027] The control unit 4 is configured to determine another empty parking space in the vicinity 2 of the vehicle 1 using the data from the sensors 3, to set the other empty parking space as the new destination parking space, and to adapt the route to the new destination parking space. Thus, the vehicle 1 is able to detect an empty parking space in the vicinity 2 during a journey from its own position at the start of the route guidance to the destination parking space and to suggest it to the driver as the new destination parking space or to set it directly. This shortens the time required to reach an empty parking space.

[0028] The control unit 4 is configured to perform an automated parking process of the vehicle in the destination parking space and to receive and / or request permission from the driver before performing the automated parking process. This allows the driver to decide independently whether to park independently or automatically upon reaching the parking space. Automated parking using the parking system 6 relieves the driver of a difficult task in addition to searching for a parking space. Furthermore, the driver does not need to access an additional assistance system, which would require additional time. If the driver were to access another assistance system for automated parking, the system would first have to obtain an overview of the surroundings 2 and the destination parking space.

[0029] The control unit 4 is configured to detect the target parking space before reaching the target parking space, to request the driver's permission to perform the automated parking process before reaching the target parking space, and to perform the automated parking process in the target parking space while the vehicle 1 is moving. The vehicle 1 is always in motion from the detection of the target parking space until the parking process is performed. According to this embodiment, a transition from guiding the vehicle 1 in the moving state to automated parking is performed by the control unit 4. This allows the vehicle 1 to move smoothly without the vehicle 1 coming to a standstill until it reaches the stop position in the target parking space.Such a flowing course of the vehicle movement is perceived by the driver as significantly more pleasant than stopping the vehicle 1 solely to request confirmation from the control unit 4 to carry out the automated parking process.

[0030] The control unit 4 is configured to receive and / or retrieve a driver input and to take the driver input into account when selecting the destination parking space. Thus, a driver's request can be adapted when selecting the destination parking space and when selecting the route from the vehicle's own position to the destination parking space.

[0031] The control unit 4 is configured to detect the target parking space in the physical environment using the sensors 3 and / or to receive and / or retrieve external information and, based on the external information, to detect the target parking space in the physical environment 2. Thus, no additional sensors 3 are required to detect the position of the target parking space. This reduces the manufacturing costs of the parking system 6. Furthermore, this provides redundant detection of the target parking space in addition to the detection of the target parking space using the route.

[0032] The control unit 4 is configured to receive and / or retrieve a distance of the vehicle 1 to a parking garage and / or parking area from the navigation system. Furthermore, the control unit 4 is configured to retrieve and / or receive an infrastructure map of the parking garage and / or parking area if a predefined distance between the vehicle 1 and the parking garage and / or parking area is undershot. In addition, the control unit 4 is configured to detect at least one empty parking space in the parking garage and / or parking area and to inform the driver of the presence of an empty parking space. Thus, the driver does not have to actively request the parking system 6, but instead receives the above information from the parking system 6 while driving. This enables the driver to be shown possible empty parking spaces where the driver did not expect them.In addition, this parallel parking system allows the driver to concentrate on the actual road layout. This increases road safety. Furthermore, the driver is only shown parking spaces within a reasonable distance. This prevents the driver from being overwhelmed by a selection of parking spaces, which would distract their concentration from the traffic.

[0033] Display 5 is configured to display data from control unit 4 and data from the navigation system. Thus, only one display 5 is required for the data from control unit 4 and the data from the navigation system. This eliminates the need for the driver to switch between multiple displays.

[0034] Fig. 3 shows a schematic representation of a method according to the first embodiment of the invention.

[0035] The invention further comprises a method 200 for parking space guidance for a vehicle 1. The method 200 comprises six steps 201, 202, 203, 204, 205, 206. In a first step 201, an infrastructure map of a parking garage and / or parking area is received. The infrastructure map indicates the occupancy of the parking spaces in the parking garage and / or parking area. In a second step 202, empty parking spaces are detected on the infrastructure map. In a third step 203, an empty parking space is defined as the destination parking space. In a fourth step 204, the vehicle's own position in the parking garage and / or on the parking area is determined and / or received. In a fifth step 205, a route from the vehicle's own position to the destination parking space is determined. In a sixth step 206, the route is output and / or provided.

[0036] This eliminates the need for the driver to search for a free parking space independently. Instead, the parking system 6 provides a route, allowing the driver to concentrate on the road layout and traffic. Using the infrastructure map, the control unit can identify empty parking spaces that a driver cannot immediately see from vehicle 1, such as a parking space behind a pillar or at the end of a parking row. This makes it easier for the driver to find a parking space and reduces the time required to reach the parking space.
