Definitions
- the present invention relates to a method and an apparatus for determining a route for a vehicle.
- Navigation systems for road applications calculate their route based on road layout and, if necessary, traffic information.
- the present invention provides an improved method and an improved device for determining a route for a vehicle according to the main claims.
- Advantageous refinements result from the subclaims and the following description.
- the quality or constitution of road conditions and thus the comfort for the driver can advantageously be taken into account.
- a status value assigned to the route section and a default value assigned to the route are taken into account.
- the state value represents a road state of the route section and the default value represents a road quality which is preferred for the route and which is independent of a road category.
- the method can be part of a navigation method in which a route leading to an end point is determined on the basis of a starting point. For this purpose, different route sections lying between the starting point and the end point can be viewed and selected taking into account predefined selection criteria and used in the route.
- a route segment can be an edge running between two nodes or as a vector in a digital map be saved.
- the route between the starting point and the end point can be composed of a route section or a plurality of route sections.
- a route criterion can relate to a distance or a travel time, for example. To determine the route, it is possible to fall back on determination methods known in connection with navigation applications. According to the present approach, road quality is taken into account as a route criterion.
- the lane quality is better, the fewer lane excitations act on the vehicle when driving on a lane comprised by the route section.
- a road excitation is caused, for example, by driving over a bump or a pothole and can lead to an acceleration of the vehicle in the direction of its vertical axis.
- the road quality preferred for driving on the route can be specified using the default value.
- At least one status value can be assigned to each route section, which can characterize the roadway condition of the route section with regard to roadway stimuli likely to act on the vehicle when driving on the route section.
- two possible alternative route sections can be selected whose state value indicates a roadway condition that corresponds to or comes closest to the preferred roadway quality indicated by the default value.
- a route section corresponding to a further route criterion can first be searched for and then a check can be made to determine whether the route section meets the preferred road quality.
- an alternative route section can be searched for and checked.
- Known comparison or selection processes can be used.
- the status value and the default value can be taken into account by comparing the status value with the default value.
- the status value and the default value can have matching formats.
- the status value can indicate a good road access Show status when the status value is set to a first value.
- the default value can indicate a good, preferred road quality if the default value is set to the first value.
- the status value can indicate a poor road condition when the condition value is set to a second value and the default value can indicate a poor preferred road quality when the default value is set to the second value. In this way, it is very easy and quick to check whether a potential route section between the starting point and the end point meets or does not meet the preferred roadway quality.
- the route section can be selected from a set of route sections.
- the set can comprise a first route section and at least one second route section that is alternative to the first route section.
- a first status value can be assigned to the first route section, which represents a road condition of the first route section
- a second status value can be assigned to the second route section, which represents a road status of the second route section.
- the first status value, the second status value and the default value can be taken into account by comparing the first status value, the second status value and the default value.
- the first route section and the second route section can have a common start node and a common end node.
- the first route section and the second route section can run completely differently or run partially overlapping. In this way, the route sections that are available can be selected from a number of the best in terms of the preferred road quality.
- the first route section can be selected as the route section if the road condition represented by the first condition value is closer to the road quality represented by the default value than the road condition represented by the second condition value.
- the second route section can be selected as the route section if the road condition represented by the second condition value corresponds to that of the The road quality represented by the default value is closer than the road state represented by the first state value.
- a suitable comparison rule can be used to compare the status values with the default value representing the preferred road quality.
- At least one other route criterion can be included. As a result, it can be ensured, for example, that the selection of the route section which is optimal with regard to the preferred road quality does not lead to an unacceptable disregard of the further route criterion. In this way, for example, an unacceptable increase in driving time or driving distance can be avoided.
- a length of the first route section and a length of the second route section can be taken into account.
- a less optimal route section can be selected if the optimal route section is considerably longer than the less optimal route section.
- a suitable threshold value can be specified which relates, for example, to a ratio of the lengths of the route sections.
- a corresponding procedure can also be applied with regard to the travel time.
- the route section and the status value can be read out from a storage device via a wireless interface.
- the storage device can be arranged externally to the vehicle and implemented, for example, as a so-called cloud.
- the route segment and the status value can represent data which are part of a digital map which is stored in the storage device. In that the digital data is stored in a central storage device, current data can always be accessed.
- the storage device can be arranged in the vehicle. In this case, a permanent radio connection is not required.
- the default value can be read in via an input device, for example in the form of a human-machine interface.
- the default can be assessed by an occupant of the vehicle via the input input device can be entered. In this way, the preferences of different occupants or temporarily changing preferences of an occupant of the vehicle can be taken into account.
- the state value can be determined using sensor data which represent data detected by sensors on a chassis of a vehicle. By means of sensors arranged on a vehicle, road stimuli acting on the vehicle can be detected. Advantageously, for this purpose, use can be made of sensors that are typically installed in a vehicle anyway.
- the status value can be assigned to the route section using position data which represent data determined by a position determination device of the vehicle. Such a position determination device is designed, for example, to determine the position data with the aid of a satellite.
- the sensor data can thus be assigned exactly to one route section. A direction of travel can also be noted.
- a state value assigned to a route section can be determined by a suitable combination of sensor data recorded with respect to the route section. For example, detected roadway excitations can be averaged, or a maximum recorded roadway excitation can be used to determine the status value.
- a corresponding device for determining a route for a vehicle has a selection device which is designed to take into account a status value assigned to the route section and a default value assigned to the route when selecting a route section of the route, the status value being a road condition of the route section and the default value represent a road quality preferred for the route and independent of a road category.
- a device can be an electrical device that processes electrical signals, for example sensor signals, and outputs control signals as a function thereof.
- the device may have one or more suitable interfaces that can be designed in terms of hardware and / or software.
- the interfaces can, for example, be part of an integrated circuit in which functions of the device are implemented.
- the interfaces can also be separate, integrated circuits or at least partially consist of discrete components.
- the interface can be software modules that are present, for example, on a microcontroller in addition to their software modules.
- Also of advantage is a computer program product with program code that can be stored on a machine-readable carrier such as a semiconductor memory, a hard disk or an optical memory and is used to carry out the method according to one of the embodiments described above when the program is on a computer or a device.
- a machine-readable carrier such as a semiconductor memory, a hard disk or an optical memory
- Fig. 1 is a schematic representation of a route according to anwhosbei game
- FIG. 2 shows a device for determining a route for a vehicle according to an exemplary embodiment
- FIG. 3 shows a flow diagram of a method for determining a route for a vehicle according to an exemplary embodiment

- the route 100 leads from a starting point 102 to an end point 104.
- Route section 1 10 or a second route section 1 12 can be selected.
- the first route section 110 is assigned a first status value which represents a roadway status of the first route section 110.
- the second route section 1 12 is assigned a second status value which represents a Fahrbahnzu status of the second route section 1 12.
- the first state value indicates that there are many bumps on the first route section 110 which, when a vehicle is traveling on the first route section 110, lead to large roadway excitations acting on the vehicle.
- the second status value shows, for example, that there are few bumps on the second route section 1 12, which when the vehicle drives on the second route section 1 12, compared to the first route section 1 10, lead to low road excitations acting on the vehicle .
- a default value is specified for route 100, which represents a road quality preferred for route 100.
- the road quality is independent of a road category. This is advantageous because, for example, a very well laid out unpaved road can have a roadway stimuli acting on a vehicle of better roadway quality than an asphalt road in need of repair.
- the second route section 112 is selected between the first node 106 and the second node 108, since the state value assigned to the second route section 112 indicates a better road condition than that of the first Route section 1 10 assigned state value.
- the first route section 1 10 and the second route section 1 12 are approximately the same length, so that by selecting the two- th route section 112 no disadvantage relating to the route arises.
- the first route section 110 is used instead of the second despite the poor road condition Route section 1 12 selected.
- the first route section 110 is also selected instead of the second route section 112 if the second route section 112 requires a considerably longer travel time than the first route section 110.
- the first route section 110 can be selected if a ratio between a travel time assumed for the second route section 112 and a travel time assumed for the first route section 110 exceeds a predetermined threshold value with regard to the travel time.
