Description

The invention relates to a method and a corresponding device for providing a route that is as comfortable as possible through a road network for a road user, in particular for a pedestrian.

Road users, in particular pedestrians, can be adversely affected by environmental influences, in particular by precipitation, on a route through a network of routes, starting from a starting point to an end point. This document deals with the technical task of increasing the comfort for a road user on a route through a road network.

The object is solved by each of the independent claims. Advantageous embodiments are described inter alia in the dependent claims. It is pointed out that additional features of a patent claim dependent on an independent patent claim without the features of the independent patent claim or only in combination with a subset of the features of the independent patent claim can form a separate invention independent of the combination of all features of the independent patent claim, which can be made the subject of an independent claim, a divisional application or a subsequent application. This applies equally to the technical teachings described in the description, which can form an invention independent of the features of the independent patent claims.

According to one aspect, an apparatus for determining precipitation information relating to precipitation and/or shelter information relating to one or more shelters in a route section of a path network (e.g. a pedestrian path network) is described. The device can be part of a vehicle-external unit, such as a server.

The device is set up to use at least one vehicle in or on the route section to determine precipitation data relating to precipitation and/or shelter data relating to one or more shelters in the route section.

• • whether the respective shelter was occupied or free at the time.

The device can also be set up to determine precipitation data and/or shelter data for a large number of different route sections of the road network. Based on this, precipitation information and/or shelter information can then be determined for the multiplicity of different route sections of the road network. The precipitation information and/or the shelter information for the different road sections can then be stored and/or made available as attributes of a digital map of the road network. In this way, efficient use of the precipitation information and/or the shelter information can be made possible.

According to a further aspect, a device for assisting a user in routing through a road network is described. The device can be part of a user device (e.g. a smartphone) of the user.

The device can be set up to determine precipitation information relating to precipitation and/or shelter information relating to one or more shelters for a plurality of possible route sections for a route to a destination using a digital map relating to the route network. The precipitation and shelter situation can thus be considered on different possible route sections.

The device can also be set up to determine the route as a function of the precipitation information and/or the shelter information for a plurality of possible route sections. The route can be determined in such a way that the burden on the user due to precipitation on the route is reduced, in particular minimized (compared to one or more other possible routes to the destination). In this way, the comfort for the user can be increased in a reliable manner.

The device can be set up, in particular, to check for a possible section of the route, on the basis of the shelter information for the possible section, whether a shelter is arranged and/or available in the possible section of the route, which has a roof with a for the indicated by the precipitation information Direction of fall of precipitation has appropriate orientation. In particular, the orientations of the roofs of the one or more shelters can be compared with the direction of fall of precipitation in order to verify whether the respective one or more shelters are effectively providing protection to the user (since precipitation does not fall in the area below the respective one shelter penetrates).

The possible leg may or may not be selected depending on the checking for the route. In particular, the possible route section can be selected if the check shows that a shelter that provides effective protection against precipitation is available in the possible route section. On the other hand, the possible leg may not be selected for the route if no suitable shelter can be identified.

A suitable route with sufficient protection against precipitation can thus be determined in a particularly reliable manner.

• • der Typ des Niederschlags 220 (z.B. Schnee, Regen, Schneeregen, etc.); und/oder
• • die Fallrichtung des Niederschlags 220 (im drei-dimensionalen Raum).

The vehicle-external unit 110 can be set up, on the basis of the precipitation data and/or the shelter data 112 of a large number of (possibly autonomous) vehicles 100, to determine corresponding precipitation information and/or shelter information with regard to one or more different route sections 201 of the route network, and, if necessary, in a digital map in relation to the road network. If necessary, the precipitation data and/or shelter data 112 for a specific route section 201, which were recorded by different vehicles 100, can be superimposed in order to determine particularly precise precipitation information and/or shelter information for the specific route section 201. The precipitation information for the particular route segment 201 can indicate

• • the amount of liquid of the precipitation 220 in the section 201 per unit time;
• • the type of precipitation 220 (eg, snow, rain, sleet, etc.); and or

The shelter information for a particular stretch of road 201 may indicate

• • the number and/or locations of the one or more shelters 203 available in the route segment 201;
• • the orientation and/or orientation of each shelter 230; and or
• • the roof area of the individual shelters 230.

3 shows an exemplary network of paths 300, which includes a large number of routes 301 (eg pedestrian paths), which are at least partially linked to one another via nodes 302. A route 301 can be subdivided into one or more route sections 201 . A digital map for the road network 300 can be provided, which shows the course and/or the position of the different routes 301 or route sections 201 and the nodes 302 .

The digital map can also have precipitation information 320 as attributes for one or more different route sections 201 (determined using the method described in this document). Furthermore, the digital map can have shelter information 330 for one or more different route sections 201 (which was determined using the method described in this document) as attributes.

The digital map can be provided to a user device 120 (e.g. a smartphone or a tablet PC) in order to enable a user of the user device 120 (using navigation software) to map a route 310 through the road network 300 from a starting point 311 to an ending point 312 to plan. The route 310 can be planned in such a way that the cumulative load (due to precipitation 220) for the user is reduced, in particular minimized. If necessary, a route section 201 where there is precipitation 220 and no suitable shelter 230 is available can be avoided.

2 B shows an exemplary shelter and precipitation situation, in which the precipitation 220 falls diagonally from the top right onto the ground 250 of a road section 201. Furthermore shows 2 B a left-side shelter 230 due to the orientation of the shelter 230 relative to the direction of the precipitation 220 is not suitable as protection for a pedestrian for the present precipitation situation, since the obliquely falling precipitation 220 penetrates into the area below the left-side shelter 230 . On the other hand, the in 2 B The shelter 230 shown on the right is suitable as protection for the present precipitation situation.

The user device 120 can be set up to determine a suitable shelter 230 for a route section 201 on the basis of the precipitation information 320 and on the basis of the shelter information 330 which is suitable as protection for the user of the user device 120 . Information related to the suitable shelter 230 can be output to the user in route guidance via the user interface of the user device 120 .

Vehicles 100 can thus be used to record sensible, real parking options 230 (possibly with a time stamp) using a stereo camera 102 while driving past. Exemplary shelters 230 (i.e., shelters) are trees, canopies, gas stations, logistics ramps, private carports, etc. Shelter data 112 relating to shelters 230 may be provided to an off-vehicle entity 110 . The vehicle-external unit 110 can optionally be set up to compare the shelter data 112 with other map data.

If there is a local risk of severe weather (e.g. recognizable by received weather data in a vehicle 100 or on a user device 120), the available and still free parking options 230 can be called up in real time by the vehicle-external unit 110 on the navigation map and a covered parking space 230 can be booked if necessary become.

An already parked (autonomously driving) vehicle 100 can be set up to carry out autonomous maneuvering without a driver to the next possible, free and accessible parking space 230 in the event of an impending storm with hail. The impending storm can be recognized on the basis of weather data.

Vehicles 100 can thus be used for data collection in order to determine public and/or private parking spaces 230 for vehicles 100 and/or for pedestrians. On the basis of current environmental data, it can be checked whether a covered parking space 230 still exists or has been removed, and/or whether a covered parking space 230 is still accessible or is only accessible to a limited extent. Furthermore, new underground parking spaces 230 can be added to the digital map.

The digital map can then be used so that vehicles 100 and/or pedestrians in particular obtain the necessary information from server 110 in the event of a short-term thunderstorm in order to look for and, if necessary, book a suitable covered parking space 230 for the duration of the thunderstorm.

4a shows a flow chart of a (possibly computer-implemented) method 400 for determining precipitation information 320 in relation to precipitation 220 and/or shelter information 330 in relation to one or more available shelters 230 in a section 201 of a route network 300. The route network 300 can, for example include pedestrian walkways and/or squares (e.g. in a city). The method 400 may be performed by an off-board entity 110 (such as a server).

Method 400 includes determining 401, using at least one vehicle 100 that is located in or on route section 201 (in particular using the environment data from one or more environment sensors 102 of vehicle 100), of precipitation data 112 in relation to precipitation 220 and/or Shelter data 112 relating to one or more available shelters 230 in the route section 201. The precipitation data and/or shelter data 112 may have been determined by the vehicle 100 by analyzing the data surrounding it.

Method 400 also includes determining 402 precipitation information 320 and/or shelter information 330 for route section 201 on the basis of precipitation data 112 or on the basis of shelter data 112. Precipitation data and/or shelter data 112 from a plurality of vehicles 100 are preferably evaluated to provide particularly precise precipitation information 320 and/or shelter information 330 for the route section 201 (which can then be stored as an attribute in a digital map).

4b shows a flowchart of a (possibly computer-implemented) method 410 for supporting a user in routing through a route network 300. The method 410 can be executed by a user device 120 of the user.

The method 410 includes determining 411, using a digital map in relation to the road network 300, precipitation information 320 in relation to precipitation 220 and/or from below Status information 330 in relation to one or more shelters 230 for a plurality of possible route sections 201 for a route 310 to a destination 312. Several different possible route sections 201 for a route to be planned 310 to a specific destination 312 can thus be checked, with regard to the precipitation 220 in the respective route section 201 and with regard to the available one or more shelters 230 in the respective route section 201. In particular, the direction of fall of the precipitation 220 and the orientation of the roofs of the one or more shelters 230 in a possible route section 201 can be compared to check whether the user can protect himself from the precipitation 220 in the possible route section 201 or not.

The method 410 also includes determining 412 the route 310 as a function of the precipitation information 320 and/or the shelter information 330 for the plurality of possible route sections 201. In particular, a route 310 can be determined on which the user (compared to one or several other routes 310) is relatively well protected from precipitation 220.

The measures described in this document can increase the comfort for a road user (in particular for a pedestrian) in an efficient and reliable manner.

The present invention is not limited to the exemplary embodiments shown. In particular, it should be noted that the description and the figures are only intended to illustrate the principle of the proposed methods, devices and systems by way of example.
