The invention provides: a method for navigating a vehicle while driving at a rest area, comprising the following method steps/actions:

• - Obtaining (querying, receiving and/or creating) map data of the rest area,
• - Capturing (querying, receiving and/or sensing) information from traffic signs at the rest area,
• - Evaluating (analyzing and/or processing) map data and information (information on service providers, directions, etc.) from traffic signs,
• - determining (automatically and/or using user input) a navigation destination on the rest area depending on the evaluation,
• - Navigate to the specific navigation destination at the rest area.

A vehicle in the sense of the invention can be both a manually controllable and an autonomous vehicle. The vehicle can have different degrees or levels of automation.

A rest area in the sense of the invention can be a facility with different recreation and/or supply service providers on roads, for example on motorways, country roads or even in the city. The rest area can be rest areas with or without service providers, such as: B. Restaurants, facilities for accommodating guests and/or selling goods, as well as with or without gas stations, charging stations, etc.

The invention recognizes that an evaluation of map data and traffic signs (“Are car gas pumps on the left or straight ahead?”) at a rest area can be of considerable advantage for navigation over the rest area.

Advantageously, the method can be further developed to recognize a passenger's request when driving at the rest area, for example whether to refuel, eat and/or rest, etc. Targeted navigation to the desired destination at the rest area can increase comfort and safety Navigating through the rest area will increase significantly.

Advantageously, when determining the navigation destination, operating parameters of the vehicle (e.g. truck, car, ... or diesel, gasoline, electric vehicle, vehicle status, tank level or battery charge level, ...), navigation parameters (travel time since last break, remaining distance, ...), user-related parameters (fatigue sensor, occupant detection, if necessary with weight detection, language recognition, daily routine times, appointment calendar data, user profiles, ...), user input ( e.g. manual and/or acoustic) etc. can be taken into account.

As part of the evaluation of traffic signs, information can be obtained, for example information about service providers (refueling/charging cars, refueling/charging trucks, rest stop, restaurant, toilet, hotel, etc.), direction information about the service providers (straight ahead, left, right) . When navigating on or via the rest area, the information and map data can be taken into account (e.g. “the next right turn”).

Vehicle-specific information (e.g. electric car or diesel truck) and/or operating parameters (e.g. vehicle status, tank almost empty, etc.) can be taken into account in order to estimate the purpose of driving on the gas station premises (e.g . Refueling, eating, ...).

As part of determining the desired navigation destination, passenger wishes (e.g. wishes to refuel, eat and/or rest) can be examined and taken into account, particularly in the case of autonomous vehicles.

The method can use operating parameters of the vehicle, navigation parameters, user-related parameters and/or user inputs to determine which destination on the rest area should be approached.

In addition, the method can provide improved positioning of the vehicle at the correct gas pump and/or charging socket when navigating to the specific navigation destination.

The invention can provide several significant advantages, particularly with regard to comfort and safety when navigating the rest area.

Claims (13)

Method for navigating a vehicle (100) when driving at a rest area (200), comprising: - Obtaining map data (201) of the rest area (200), - Recording information from traffic signs (202) at the rest area (200), - Evaluating map data (201) and information from traffic signs (202), - determining a navigation destination (203) on the rest area (200) depending on the evaluation, - Navigate to the specific navigation destination (203) at the rest area (200). Procedure according to Claim 1 , wherein at least one of the following sources is used to obtain map data (201) of the rest area (200): - a vehicle-internal navigation device (130), - a user-side mobile device, - a communication device of the rest area (200), - a communication device of a service provider the rest area (200), and/or - a communication device of other road users, in particular via wireless communication, mobile communications, WLAN, NFC, etc., preferably using V2X communication, V2I communication, V2V communication, etc. Procedure according to Claim 1 or 2 , wherein at least one of the following devices is used to record information from traffic signs (202) on the rest area (200): - an in-vehicle sensor device (120), - an in-vehicle navigation device (130), and / or - an in-vehicle and / or user-side communication device (140), which in particular uses wireless communication, mobile communications, WLAN, NFC, etc., preferably using V2X communication, V2I communication, V2V communication, etc. Method according to one of the preceding claims, wherein at least one user input is taken into account when determining a navigation destination (203) on the rest area (200). Method according to one of the preceding claims, wherein when determining a navigation destination (203) on the rest area (200), at least one operating parameter (BP) of the vehicle (100) is taken into account, in particular comprising: a type of vehicle (100), a type of drive of the vehicle (100), a degree of automation of the vehicle (100), an operating mode of the vehicle (100), a tank level, a charge status of a battery, a range of the vehicle (100), a load status of the vehicle (100), etc. Method according to one of the preceding claims, wherein when determining a navigation destination (203) on the rest area (200) at least one user-related parameter (BB) is taken into account, in particular comprising: number of occupants, weight of the occupants, age of the occupants, physiological properties, such as e.g. E.g. heartbeat, eye position, calendar data, daily routine data, user settings, user profiles, etc. Method according to one of the preceding claims, wherein at least navigation parameters (NP) are taken into account when determining a navigation destination (203) on the rest area (200), in particular comprising: a journey time since the start of a journey, a journey time since a last break, a remaining journey time and/or remaining distance to a planned journey destination, etc. Method according to one of the preceding claims, wherein the navigation destination (203) comprises at least one of the following service providers on the rest area (200): - rest stop, - charging station as a fuel station, - gas station as a fuel station, - restaurant, - toilet, - purchase of goods, etc. Method according to one of the preceding claims, wherein the method is started automatically when it is recognized that the vehicle (100) is navigating to the rest area (200) and/or is approaching the rest area (200). Computer program product, comprising instructions which, when the computer program is executed by a computer, cause the computer to carry out a method according to one of the preceding claims. Control device (110) for navigating a vehicle (100) when driving on a rest area (200), comprising: a storage device and a computing device, wherein a code is stored in the storage device, and wherein when the code is executed by the computing device, a method according to one of the preceding claims is carried out. Control device (110) according to the preceding claim, wherein the control device (110) is designed to carry out at least one of the following method steps: - Obtaining, querying, receiving and/or creating map data (201) of the rest area (200) and/or information from traffic signs (202) on the rest area (200), - Evaluating, analyzing and/or processing map data (201) and information from traffic signs (202), - determining a navigation destination (203) on the rest area (200) depending on the evaluation, - Controlling a navigation device for navigating to the specific navigation destination at the rest area (200). Vehicle (100) comprising a control device (110) according to the preceding claim.
