The evaluation device goes 28 after performing the comparison functions, automatically enter a deep sleep mode of operation, at regular intervals of 10 minutes from the first timer 24 or a second timer (not shown in the figure) is transferred to the normal operating mode for performing the comparison work.

In a further embodiment, the transfer of the evaluation device takes place 28 in the normal operating mode interrupt-controlled (interrupt-controlled) in response to external events.

In Another embodiment generates at least one the temperature sensors when exceeding or falling below a temperature limit, an interrupt signal (interrupt signal) for transfer the evaluation device in the normal operating condition for implementation the comparison work.

In another embodiment, the timer generates 24 an interrupt signal for the transfer of the evaluation device in the normal operating condition for performing the comparison work. For this purpose, the switch-on times of the evaluation device 28 transmitted to the timer and stored there. The timer 24 then generates interruption signals for the transfer of the evaluation device into the normal operating state for carrying out the comparative work as a function of the switch-on times stored in it.

In a preferred embodiment, the evaluation device 28 not intended to store and process turn-off times, but only to store and process only a single turn-on time. Then, upon receipt of a new switch-on time, the previous switch-on time in the memory of the evaluation device 28 overwritten with the new switch-on time. The evaluation device 28 compares a time value over the line 26 from the timer 24 transmitted time after each transmission with a time value in the evaluation 28 stored information about the switch-on. If that of the timer 24 delivered and current time is equal to or greater than a time value corresponding to the time of switch-on minus one of the air conditioning 46 expected to require warm-up time of the passenger compartment 16 , performs the evaluation device 28 a second comparison.

In a likewise preferred embodiment, the evaluation device 28 intended to simultaneously hold several switch-on times E1, E2, E3, E4, E5 and switch-off times A1, A2, A3, A4, A5.

2 outlines an arbitrary example of simultaneously stored switch-on times E1, E2, E3, E4, E5 and switch-off times A1, A2, A3, A4, the arrangement of which corresponds to their respective value with respect to the time axis t. The evaluation device 28 can also use the stored switch-on times E1, E2, E3, E4, E5 and switch-off times A1, A2, A3, A4 in an expedient manner for activating and deactivating the warning function for exceeding the temperature limit if two switch-on times E3, E4 follow each other accidentally or two switch-off times A1, A2 follow each other. The evaluation device 28 has a kind of fault tolerance. For this purpose, all times are first brought into a chronological order, ie sorted, regardless of whether it is about switch-on or Off time is. Time pairs or time multiples of the same kind falling exactly at the same point in time, that is to say all times represent a switch-on time or all of which represent a switch-off time, are deleted from the memory except for a time of the pair or multiples. Then, all timing pairs falling at exactly one point in time, in which one of the two times represents a switch-on time while the other of the two times represents a switch-off time, are deleted from the memory. In addition, all switch-off times are deleted, which directly follow a switch-off time. In the example of the figure, this is the switch-off time A2. In addition, all turn-on times are deleted that directly follow any turn-on time. In the example of the figure, this is switch-off time E4.

The timestamps Z1, Z2 and Z3 shown in the figure symbolize the temporal position of exemplary selected times. In each first comparison, one of the search algorithms generally known from textbooks, such as a halving method, of the remaining on and off points in the memory of the evaluation device 28 a lower on or off time L1, L2, L3 is sought, which has the largest time value of all those on or off times that have a smaller time value than the time stamp. The activation and deactivation of the warning function for exceeding the temperature limit value is realized by carrying out the second comparison at a time Z1, Z2, Z3 only if the determined lower switch-on or switch-off time L1 = A1, L2 = E2, L3 = E3 is a switch-on time is. In the example of the figure, this applies to the time marks Z2 and Z3.

alternative can use the search algorithm an upper on or off time U1, U2, U3, of all those on or off times, which has a greater time value than the timestamp have the lowest fair value. In this case, the Activation and deactivation of the temperature limit warning function realized by the second comparison at a time Z1, Z2, Z3 is performed only if the determined upper on or off time L1 = E2, L2 = A3, L3 = A4 is a switch-off time. In the example of the figure meets this also on the time stamps Z2 and Z3 too.

To carry out the second comparison, the evaluation device compares 28 that of the temperature sensor 50 in the passenger compartment 16 measured and over line 58 provided temperature value with one in the Auswertevorrich device 28 stored temperature limit. The evaluation device 28 then, if and only if the measured temperature value exceeds the temperature threshold, generates an alert signal for transmission to the mobile mobile station 64 , The warning signal is sent via the interface 32 to the transmission part 40 the mobile station 30 of the vehicle 10 transmitted. The mobile station 30 generates a high-frequency signal by coding the indication signal and modulating a high-frequency carrier with the coded indication signal. The high-frequency signal is via interface 36 to the transmitting antenna 44 of the vehicle 10 transmitted and from the transmitting antenna 44 as a radio signal 92 radiated. The radio signal 92 is from the receiving antenna 76 the mobile mobile station 64 via an already existing mobile network or directly received and the mobile receiver 68 fed. The mobile receiver 68 demodulates and decodes the received signal. The decoded signal is sent over one line 94 for mobile control 82 transmitted. The mobile control 82 translates the decoded signal into an electrical signal for the display unit 72 , About a line 96 the electrical signal becomes the display unit 72 transmitted and from the display unit 72 brought to the display. In a simple embodiment, the display unit consists 72 essentially a light emitting diode, which is lit by the electrical signal. The light of the LED is illuminated by the user when viewing the display unit 72 perceived. From the glow of the LEDs, the user can conclude that in the passenger compartment 16 measured temperature limit has been exceeded. In this way, the user is above an excess of the temperature limit in the passenger compartment 16 notified. Due to the upstream time comparison, the notification can not take place before the switch-on time minus the expected cooling or warm-up time. It does not take place as in previous generic vehicles 10 at a time when such notification is likely to be of little interest to the user and thus constitutes a disruption. In the vehicle according to the invention 10 on the other hand, the reference to the expected optimal time for the user takes place. That is the time when the air conditioning 48 can be put into operation just in time to the vehicle interior 16 to pre-cool or preheat to the scheduled start of the journey.

In another embodiment, the air conditioner 48 thermally to the fuel cell system 50 or the engine 18 coupled to the fuel cell system 50 or the engine 18 preheat or pre-cool towards an optimum operating temperature. The rest of the procedure is analogous as for the air conditioning of the passenger compartment 16 described, in which case instead of the Temperature values from the temperature sensor 52 of the passenger compartment 16 that of the temperature sensor 54 or from the temperature sensor 56 determined temperature values are used for the second comparison.

In a further embodiment, the order of the two comparison steps is temporally reversed. Then the second comparison is made before the first comparison, preferably always. In this case, the sending of the indication signal to the mobile mobile station becomes 64 however, only from the evaluation device 28 caused, if it is determined in the subsequent first comparison that the current time is not in one of the deactivation periods P2, P4, P6, but in one of the activation periods P1, P3, P5.

In a further embodiment, the switch-on and / or switch-off are by previous uses of the vehicle 10 as a vehicle or as a lounge 16 or as a cargo hold or as a fuel cell powered power source 50 determined or codetermined. A prior use of the vehicle 10 as a vehicle is of the evaluation device, for example, based on a by the temperature sensor 56 determined elevated temperature of the engine 18 recognized. A prior use of the vehicle 10 as a lounge 16 or cargo space is from the evaluation device, for example, based on a through the temperature sensor 52 ascertained elevated temperature of the passenger compartment 16 recognized. A prior use of the vehicle 10 as a fuel cell powered power source 50 is from the evaluation device 28 for example, based on a through the temperature sensor 54 determined elevated temperature of the fuel cell system 50 recognized.

In one embodiment, the evaluation device stores 28 the time of a previous temperature increase over a predetermined upper temperature limit as the switch-on and stores the time of a previous decrease in temperature below a predetermined lower temperature limit as the switch-off. This procedure can be used by anyone at the evaluation device 28 connected temperature sensors 52 . 54 . 56 be applied.

The mobile receiving or transmitting or mobile station 64 was referred to by the attribute "mobile" to explicitly call it from the first (vehicle-mounted) mobile station 30 to distinguish. However, this does not rule out that the station 64 is arranged stationary and / or connected to a landline. To receive the notification signal from the vehicle 10 can the mobile receiving station 64 be connected to a communication network via a fixed wired or a stationary further radio connection. The transmission of the warning signal from the vehicle 10 then takes place via a first base station connected to the stationary wired connection or to the stationary further radio connection. To send the selection signals to the vehicle 10 can the mobile station 64 also be connected to a communication network via a fixed wired connection or via a fixed radio connection. The transmission of the selection data to the vehicle 10 then takes place via a second base station, which is connected to the fixed wired connection or to the stationary further radio connection and which may be identical to the first one.

Between the mobile receiving station 64 , the mobile broadcasting station 64 or mobile mobile station 64 and the vehicle 10 a logical binding to a vehicle - for example by means of a signal coding - be provided such that the mobile station 64 only with exactly one vehicle 10 communicates with whom it is associated. By means of a changeable signal coding, it is also possible to use the mobile station 64 to provide that they can optionally with one of several vehicles 10 or even simultaneously with several of several vehicles 10 - which belong for example to a vehicle fleet - to communicate.

In a further embodiment, functions of the evaluation device 28 like the comparison functions, instead of in the vehicle 10 on the network side, for example in the case of a base station, or on the user side, for example in the mobile mobile station.

The invention allows, for example, that the user of a passenger car 10 , which is next to a combustion engine 18 one from a fuel cell system 50 stand-alone air conditioning system that can be supplied with electrical energy 48 indicates that the passenger car 10 on weekdays between 7:00 and 20:00 and on other days between 9:00 and 22:00 via a mobile network to the user asks if the car 10 regardless of the operation of the internal combustion engine 18 should be pre-cooled, if the interior temperature in the vehicle 10 Exceeds 25 ° C. Of course, the "allowed" request times and the or the temperature limits can be specified by the user. In a particularly preferred embodiment of the invention, the vehicle is able to "learn" when the user with a relatively high probability desires a Vorklimatisierung, and the request times of the learned at least in a corresponding operating mode thereof dependent on do.

Even though the invention above, for example, by land vehicles Of course, she is not up this limited. Rather, the invention may be equally advantageous used in connection with water or airplanes.
