The additional information is received by an external transmitting unit and/or is stored in a memory on board the vehicle. A check takes place during the drive as to whether the route recommendation remains optimal, and a further optimal route determination is triggered if it does not.
BACKGROUND AND SUMMARY OF THE INVENTION This application claims the priority of German patent application 102 00 759.4, filed 10 Jan. 2002, the disclosure of which is expressly incorporated by reference herein.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic block diagram of a vehicle destination routing system according to the invention;
DETAILED DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic representation of a vehicle destination routing system with a first system part 10 fixedly installed in the vehicle and a portable second system part 20 with a wireless or wire-bound data connection 30. The driver or user can establish the data connection, for example, by plugging the portable system part 20 into a receiving device. The receiving device then establishes the data-related connection with the first system part 10, whether it is wire-bound or wireless. The wireless data connection can be implemented, for example, by way of infrared and/or radio, such as Bluetooth. For this purpose, the corresponding interface, such as Bluetooth, may also be integrated directly in the portable system part.
Data which are exchanged by way of the data connection 30 between the system part 10 fixedly installed in the vehicle and the portable system part 20 may comprise, for example, the information indicated in FIG. 1, such as the trigger for a new route computation 32, the set of �static� alternative routes 34, the �dynamically� optimal route 36, the vehicle position 38 and/or the explanatory information for the driver 42.
The portable system part 20 comprises a memory 80, particularly for stored �off-line� traffic data/information, with an associated analyzing unit 90, a transmitting/receiving device with an analyzing unit 70 for additional information available �on-line�, which is received either by way of a broadcasting channel or is received and/or requested by way of a bi-directional channel and is then received. The portable system part 20 also includes a unit 100 for determining the optimal route from the set of static alternative routes 34. The unit 110 monitors real parameters and compares them with parameters assumed when determining the optimal route. For determining the real driving progress, the unit 110 receives the vehicle position 38 from the system part 10 by way of the data connection 30. A digital map may also be stored in the memory 80, which map is sufficiently detailed to permit the unit 110 to image the driving progress and the additional information on the digital map. The unit 120 generates explanatory information 42, which is transmitted to the system part 10 via the connection 30 and emitted by the output unit 62.
FIG. 3 is a flow chart that illustrates an example of the determination of a dynamically optimal residual route during the drive. In Step 150 an inquiry is made whether the actual driving progress corresponds to the driving progress used as the basis when computing the optimal route in Step c). If not, (�no� branch), the route computation 32 trigger is set. In addition, it is advantageous in this situation to optionally, in Step 152, supply explanatory information 42 to the driver, explaining that contrary to expectations, the drive will take place in a manner that is different than planned, and that the system is working on the problem. This increases the acceptance of the system, because the driver will not feel abandoned in the event of a contradiction between reality and assumptions of the system.
If real parameters and assumed parameters do not correspond to one another (�no� branch in Step 150), or if new additional information is present (�yes� branch in Step 160), the trigger 32 is set again, and the computation of a set of residual routes by the module 52 is triggered in step aa). The set of residual routes includes those (multiple) routes which lead from the current location of the vehicle to the destination location. Then, analogous to the set 34 of routes, the module 52 forwards the set of residual routes to the system part 20, where the relevant additional information for this set of residual routes is determined in Step bb). The optimal residual route is then determined (Step cc)) in module 100 taking into account the dynamic relevant additional information, analogous to the optimal route 36.
