However, the figures are only to be considered as examples of different embodiments of the invention and should not be construed as limiting the invention, which is limited only by the appended independent claims. Furthermore, the figures are not necessarily to scale, and are, unless otherwise specifically indicated, intended to conceptually illustrate aspects of the invention.

Figure 1A shows a vehicle 100 traveling in a direction of travel 1 along a route. Inside the vehicle 100, for example in the cab, there is a navigation unit 1 and a monitor 130, connectable to the navigation unit 120. 537 714 Figure 1B shows an example of the driver environment in the vehicle 100. In the vehicle 100 is the navigation unit 120, which includes or is connected to the monitor 130.

The navigation unit 120 has access to information for all planning a route for the vehicle 100, such as map data, previous destinations, attributes for various road sections such as barity classification, type of road, speed limit, etc., points of interest (Points of Interest or POIs), and / or vehicle information previously stored or configured by the vehicle's driver, or read by detectors / sensors such as the vehicle's weight, length, width, axle load, presence of connected truck, dangerous goods, lost goods in the cargo space and the like.

This allows you to avoid wagons where certain vehicles 100 such as trucks and / or caravans are not allowed, narrow streets and repair bridges and tunnels. The points of interest, or POIs, may include, for example, gas stations, shops open on call, lorries, or other places, including those that the driver has entered in the navigation unit 120 for various reasons in previous cases.

Figure 1C schematically shows a vehicle 100. The navigation unit 120 is arranged for communication with an analysis unit 1 in the vehicle 100. This communication can be made over a wireless, or a wired interface according to different embodiments. The analysis unit 150 may be located at any position in, or adjacent to, the vehicle 100. The analysis unit 150 may be a separate independent unit, or be included in another unit. For example, the analysis unit 150 may be included in the navigation unit 120 according to certain embodiments.

The analysis unit 150 is also arranged to receive all signals from, or all to communicate with, one or more detectors 140. Examples of such detectors may be fuel level feeders, urinary feeders, washer water level feeders, oil level feeders, fault detectors in the engine, detectors indicating a lamp, , tire pressure detector, load lashing detector, dirt indicator, cooling water temperature feeder, electrical fault or other similar detector in, or adjacent to the vehicle 100.

The analysis unit 150, the detector 140 and the navigation unit 120 can communicate with each other via a wired or wireless interface.

The wired interface may, for example, be based on any of the following technologies in the vehicle 100: Controller Area Network (CAN), Media Oriented Systems Transport (MOST), Ethernet. According to some embodiments, the wired interface may, for example, be based on the flag of the following technologies: Ethernet, Universal Serial Bus (USB), SerieII RS232, FireWire, 10 Thunderbolt, may now only name a few possibilities.

For example, the wireless interface may be based on any of the following technologies: Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Access (CDMA), (CDMA 2000 ), Time Division Synchronous CDMA (TD-SCDMA), Long Term Evolution (LTE); Wireless Fidelity (Wi-Fi), as defined by the Institute of Electrical and Electronics Engineers (IEEE) standards 802.11 a, ac, b, g and / or n, Internet Protocol (IP), Bluetooth and / or Near Field Communication, (NEC ), according to different embodiments.

Through all collected data related to a restriction of the vehicle 100 from the detector 140, it is possible for the analysis unit 150 to formulate a request for a new route for the vehicle 100 having the navigation unit 120, where the new route has a route characteristic which corresponds to the restriction detected. in the vehicle 100. An example of this may be when a torque reduction is active or will become active within a predefined time, then it may be appropriate to all choose a route with few or no steep uphill slopes. It can instead be convenient to choose a longer route with fame slopes. Another example of this is the use of the amount of fuel, urea, etc. as a limiting factor, that is to say; it is not advisable to take a route where the industry or urea is expected to run out before there is any suitable place under the route where it is possible to fill these. 7 537 714 The request for a new route for the vehicle 100, which is sent from the analysis unit 150, can be used by the navigation unit 120 to calculate a new route and also calculate the remaining short time to, for example, a petrol station, if it is industry shortage that is the limiting factor. As a result, the driving route can be modified as any deficiencies in the vehicle's performance arise, so that the effect of these deficiencies can be eliminated, or at least reduced.

Figure 2A shows a schematic example of route planning for the vehicle 100, visualized on a screen 130. A dashed line indicates the new route 2 which the navigation unit 120 has calculated all the vehicle 100 should take, as the calculation unit 150 has requested a route having a filling station. as a result of all the detector 140 has detected that the industry is slowing down. The navigation unit 120 can then plan for a new route 220 which has a route feature 210, in this case a filling station, which makes the industry shortage avoidable. This allows the driver to obtain information about the new route as a result of the shortcoming of the vehicle 100 and the final destination 230 can be reached. In the illustrated example in the figure, only a new route 220 is indicated which has the requested route property 210. However, Della is only an example. In other examples, the navigation unit 120 may instead calculate a plurality of new routes 2 having the requested route feature 210 and present these to the driver of the vehicle, who may then make a choice.

In the case illustrated in Figure 2A, the driver is given information about the new route in the form of an illustration on a map, but one can also, or in addition, imagine, for example, spoken instructions that give driving instructions, and / or all the route is presented in list form, which askadliggors in Figure 2B.

In some embodiments, more than one route feature 210 along the route 220 may be displayed to the driver. This can thus be given the opportunity to, for example, compare the various proposed route characteristics 210 with each other and select one of them for vehicle stops, which basically correspond to the needs of the vehicle, and / or to the driver's wishes. 8 537 714 Figure 2B shows a schematic example of route planning for the vehicle 100, visualized on a screen 130, where the new route is presented in text form to the driver.

Della may be a complement, or alternative, to the presentation of the new route 220 shown in Figure 2A.

Figure 3 shows an example of how a route 220 can be planned in a navigation unit 120 in the vehicle 100, where the route 220 has a certain route characteristic 210. The combined river and signaling scheme in Figure 3 detracts a procedure in tic steps for planning route 220 It should be noted, however, that some of the steps 1-10 described may be performed in a slightly different chronological order from what the numbering order suggests and that some of them may be performed in parallel with each other, according to different embodiments. Furthermore, not all of the described steps 1-10 necessarily occur in all embodiments.

In a first step, the detector 140 may be assumed to be a defect in the vehicle 100. As previously mentioned, the vehicle may contain a plurality of detectors 140 in certain embodiments, arranged to detect faults and defects of various kinds in the vehicle 100, but for example one of these detectors 140 detect a certain action and emit a signal to the MIA thereof. This signal is received by the calculator 150.

The detector 140, or respective detector 140 may send a signal indicating the state of the monitored unit to the calibration unit 150, either in response to a request sent from the calibration unit 150, or with a certain time interval according to different embodiments, such as every second, each minute, habit quarter, habit half hour, hourly or other similar interval comprising a multiple of any of the above intervals by multiplication by any positive integer. But the detector 140 can also be arranged to send a signal with such an indication when a defect is encountered. 9,537,714 In some embodiments, the detected driver deficiency is displayed on the monitor 130, such as "low industry level", or "puncture on Niger rear deck". In this way, the Product itself can adapt the grain to the resulting defect in the vehicle, and possibly take appropriate action to follow it.

When the calculation unit 150 receives information from the detector 140 of a certain transaction occurred in the vehicle 100, an analysis is made of what action the detected defect gives rise to. Such analysis may, for example, include a mapping of detected deficiencies, against an atgard in a memory. For example, the lack of "5 liters of fuel left in the tank" may cause the yard to "find a route with a filling station 10 within 12 kilometers"; the lack of "torque reduction in the engine" can lead to the action "find a route with as few uphill slopes as possible", etc.

Thereby, the travel route 220 provided for the vehicle 100 can be optimized, or at least in some respects improved with respect to operating economy, including the aspects of time and / or cost. Driving a heavily loaded crew up a steep hill with a torque reduction in the engine gives low average speed and thus a delayed delivery, which can be avoided by choosing a new route 220 instead.

When the calculation unit 150 has calculated an action, or route property 210 that is suitable, based on the detected defect, a request is sent to the navigation unit 120 for a route route 220 which has the calculated route route property 210.

The navigation unit 120 may then select one or more alternative routes 220 for the vehicle 100, which possesses the requested route property 210. In some embodiments, it may appear that the existing planned route 220 has the requested route property 210. In this case, the route 220 does not change, but optionally, the requested route feature 210 is added as a sub-template, if this is applicable, for example a gas station in the event of a shortage of fuel. In other cases, it may turn out that all the previously planned route 220 towards the final destination 230 does not have the requested route property 210. In this case, the navigation unit 120 may select a new route 220, or several new alternative routes 220 for the vehicle 100, which possess the requested route property. 210. 537 714 The new or modified route 220 can then be displayed on the driver screen 130. The driver is then given the option to select the presented route or routes 220. When the driver selects a new route 220, the navigation unit 120 can receive this information and enter the new route 220 in the navigation unit 120, as a stored route 220 according to certain embodiments. The navigation unit 120 can cla store this route 220 selected by the driver in a memory. Thereby, route 220 can be planned so that it corresponds to a defect or malfunction of the vehicle 100. Figure 4 illustrates an example of an embodiment of the invention. The flow chart in Figure 4 ashes a method 400 in a navigation unit 120 in a vehicle 100, for planning route 220 for the vehicle 100 when the vehicle 100 is affected by a restriction in its passability.

In order to enable such route planning for the vehicle 100 in a correct manner, the method 400 may comprise a number of steps 401-404. It should be noted, however, that some of the described steps 401-404 may be performed in a slightly different chronological order from what the numbering order suggests and that some of them may be performed in parallel with each other, according to different embodiments. Furthermore, certain process steps such as step 404 are not necessarily mandatory in all embodiments of method 400. Method 400 includes the following steps: Step 401 A request for a route 220 with a route feature 210 is received from an analysis unit 150 in the vehicle 100.

Such route feature 210 may include, for example, some sloping slope below a predetermined spruce value, gas station, vehicle repair shop, or the like. In some embodiments, the received request for a route 220 with a route feature 210, from an analysis unit 150 in the vehicle 100, may also include an indication of a detected vehicle-related transaction, which may be displayed to the Waren. In this case, the driver can be given the opportunity to give others a magnitude associated with the detected vehicle-related transaction.

Step 402 A route 220 possessing the received route property 210 is selected for the vehicle 100.

According to certain embodiments, at least two separate routes 220 may be selected for the vehicle 100, with the driver of the vehicle being asked to make the final choice of route 220 for the vehicle 100.

Step 403 The selected 402 route 220 is presented on a screen 130, so that the driver is given the opportunity to select this route 220, or reject it and instead continue the original route.

According to certain embodiments, at least two separate routes 220 may be presented, with the driver of the vehicle being asked to make the final choice of route 220 for the vehicle 100.
