DETAILED DESCRIPTION

[0071] Elements having the same design or function are denoted by the same reference signs across the figures.

[0072] The motor vehicle 1 according to the exemplary embodiment of FIG. 1 comprises an apparatus 6, having a sensor unit 5 designed to ascertain the actual state IZ of the motor vehicle 1. Furthermore, the apparatus 6 in this exemplary embodiment comprises a telecommunication unit 7. Moreover, the motor vehicle 1 comprises a navigation apparatus 9.

[0073] The motor vehicle 1 is an electric vehicle that is driven exclusively electrically. That is to say that the motor vehicle 1 comprises a battery 3 as the energy source for an engine of the motor vehicle 1.

[0074] The telecommunication unit 7 of the apparatus 6 is used to transmit the actual state IZ of the motor vehicle 1 to an external apparatus 4, which is in particular a remote server.

[0075] In order to prepare for a journey, a first piece of information I1 is recorded by a mobile electronic device 2. The mobile electronic device 2 is not integrated in the motor vehicle 1 in this instance. Furthermore, the first information I1 is transmitted to the external apparatus 4, in particular to the remote server, by way of a telecommunication unit 8 of the mobile electronic device 2.

[0076] On the external apparatus 4, it is then possible to determine a piece of preparatory information VI on the basis of the first information I1 and the second information I2. In this instance, at least one piece of preparatory information VI is determined on the basis of the first information I1 and the second information I2 and is displayed on the mobile electronic device 2 in order to prepare the motor vehicle 1.

[0077] In this exemplary embodiment, the preparatory information VI comprises a route for the journey, which is provided to the navigation apparatus 9 of the motor vehicle 1.

[0078] Furthermore, a third piece of information I3 can be provided by the apparatus 6. In this case, the third information I3 is transmitted to the external apparatus 4 by way of the telecommunication unit 7 of the apparatus 6. Alternatively, the third information I3 can be provided by the mobile electronic device 2. In this case, the third information I3 is transmitted to the external apparatus 4 by way of the telecommunication unit 8 of the mobile electronic device 2. Alternatively, the third information I3 is provided by the external apparatus 4.

[0079] The apparatus 6 according to the exemplary embodiment of FIG. 2 comprises a sensor unit 5, which in particular has a multiplicity of sensors. The multiplicity of sensors are used to ascertain the actual state IZ of the motor vehicle 1. Furthermore, the apparatus 6 comprises a telecommunication unit 7.

[0080] In the flowchart for the method according to the exemplary embodiment of FIG. 3, a step A1 is first performed, in which a first piece of information I1, which is representative of a piece of journey information FI, is provided. In this exemplary embodiment, the journey information FI comprises at least one piece of arrival information and a piece of intermediate information. The arrival information in this instance comprises an arrival location and an arrival time. The intermediate information comprises an intermediate stop location. The arrival location and the arrival time are input into a mobile electronic device 2 by the user of the motor vehicle 1 by voice input, for example (see FIG. 1).

[0081] In a further step, a step A2 is performed, in which a second piece of information I2, which is representative of at least one actual state IZ of the motor vehicle 1, is ascertained. In this exemplary embodiment, the motor vehicle 1 furthermore comprises at least one sensor unit 5 (see FIG. 1) that is used to ascertain the actual state IZ of the motor vehicle 1. Here, the actual state IZ comprises a tire pressure, a battery charge, the power consumption and location data, in particular the present location, of the motor vehicle 1.

[0082] Subsequently, in step B, at least one piece of preparatory information VI is ascertained on the basis of the first information I1 and the second information I2.

[0083] In this exemplary embodiment, the preparatory information VI is ascertained on the basis of the arrival location, the arrival time, the battery charge, the power consumption, the tire pressure and the present location.

[0084] The ascertained preparatory information VI is then displayed on the mobile electronic device 2 in order to prepare the motor vehicle 1. In this exemplary embodiment, the preparatory information VI comprises an optimized route from the present location to the arrival location. The optimized route is geared for an increase in a range of the motor vehicle 1 for the journey. Furthermore, the preparatory information VI comprises a piece of information that the user of the motor vehicle 1 should increase the tire pressure of the motor vehicle 1. An increased tire pressure of the motor vehicle 1 leads to a lower power consumption and/or fuel consumption. An additional interruption to the journey along the route could thus be advantageously avoided.

[0085] In contrast to the flowchart for the method according to the exemplary embodiment of FIG. 3, the flowchart for the method according to the exemplary embodiment of FIG. 4 comprises a further step A3, in which a third piece of information I3, which is representative of at least one piece of path information SI, is provided. In this exemplary embodiment, the path information SI comprises a weather forecast during the journey.

[0086] In a subsequent step B, the preparatory information VI is determined on the basis of the first information I1, the second information I2 and the third information I3. Here, the preparatory information VI is ascertained on the basis of the arrival location, the arrival time, the battery charge, the power consumption, the tire pressure, the present location and the weather forecast.

[0087] The preparatory information VI displayed on the mobile electronic device 2 comprises, among other things, an optimized route from the present location to the arrival location, wherein a region in which it is probably raining very heavily is bypassed. The bypass means that the journey is effectively faster.

[0088] Furthermore, it is possible that a very high outside temperature is forecast for another region, which preferably corresponds to the departure location. The external apparatus 4 is then designed for example to switch on an air-conditioning system of the motor vehicle 1 by means of change signals before the journey begins in order to reduce the interior temperature of the motor vehicle 1 before the journey, so that the user of the motor vehicle 1 can advantageously get into an air-conditioned motor vehicle 1 when the journey begins.

[0089] In contrast to the flowchart for the method according to the exemplary embodiment of FIG. 4, the flowchart for the method according to the exemplary embodiment of FIG. 5 comprises a further step B1, in which at least one intermediate question ZF is determined when determining the preparatory information VI.

[0090] Here, the preparatory information VI is determined on the basis of a predefined information threshold I.sub.Thr. The predefined information threshold I.sub.Thr indicates whether sufficient first information I1, in particular collective information I.sub.G, is available so that the preparatory information VI can be determined particularly effectively. The collective information I.sub.G here comprises the first information I1 or the first information I1 and the further first information I11. If the collective information I.sub.G is above the predefined information threshold I.sub.Thr, the preparatory information VI is displayed on the mobile electronic device 2 in step B.

[0091] If this predefined information threshold I.sub.Thr is not reached, then at least one intermediate question ZF is determined in step B1. The intermediate question ZF here comprises a question to clarify the first information I1, such as the journey information FI. That is to say that the intermediate question ZF in this case comprises a question concerning the journey route FS. By way of example, the intermediate question ZF comprises a question to the user of the motor vehicle 1 regarding whether an interruption to the journey along the route is wanted.

[0092] In a subsequent step B2, the mobile electronic device 2 records at least one further piece of first information I11, which is representative of at least one further piece of journey information WFI. By way of example, the user of the motor vehicle 1 inputs the further first information I11 into the mobile electronic device 2. The user of the motor vehicle 1 inputs for example that an interruption to the journey along the route is wanted and clarifies the interruption to the journey along the route by indicating a piece of location-related interruption information.

[0093] If the collective information I.sub.G is above the predefined information threshold I.sub.Thr, the preparatory information VI is determined in a further step B3 on the basis of the first information I1, the second information I2, the third information I3 and the further first information I11. Here, the preparatory information VI is displayed on the electronic device 2 on the basis of the arrival location, the arrival time, the battery charge, the power consumption, the tire pressure, the present location, the weather forecast and the location-related interruption information.
