This object is solved by an electronic computing device, an arrangement as well as by a method according to the independent claims. Advantageous forms of configuration are specified in the dependent claims.
An aspect of the invention relates to an electronic computing device for a motor vehicle with at least one electronic circuit, which is inactive and operated with a first electrical voltage in a first operating mode of the electronic computing device and which is active and operated with a second voltage in a second operating mode different from the first operating mode, and with a first voltage supply device for providing the first voltage.

Thereby, it is allowed that an additional voltage supply device does not have to be provided on or in the electronic computing device for the second operating mode, which in particular requires a voltage different from the first voltage. Thus, the electronic computing device can be operated in the first operating mode and in the second operating mode reduced in components.
In other words, the second voltage supply device is outside of the electronic computing device and in particular separate from the electronic computing device. Only if the control device external to computing device is connected to the electronic computing device, thus, the second voltage is provided for the electronic circuit via the control device external to computing device. In other words, the electronic circuit is supplied with the second voltage of the control device external to computing device in the second operating mode.
In the first operating mode, the electronic computing device is in particular in a normal operation, for example in a drive operation. The electronic circuit is in particular inactive in this operating mode, but still requires a supply voltage to for example be able to provide better electromagnetic compatibility (EMC). In the first operating mode, the electronic circuit is thus supplied with the first voltage of the voltage supply device internal to computing device. Now, if the electronic computing device should be operated in the second operating mode, thus, the electronic circuit is activated and supplied with the
voltage by the second voltage provided by the control device external to computing device. The second voltage is in particular different from the first voltage. In particular, the first voltage is formed between a minimum and a maximum of a supply limit.

Thus, it is allowed in simple manner that it can be switched between the first voltage supply device and the second voltage supply device.
It has further proven advantageous if the switching element is formed to perform a switching operation in the contacted state of the control device external to computing device such that the electronic circuit is supplied with the second voltage.

Then, the control device 7 external to computing device can for example be coupled to the supply interface 8 via the further supply interface 9 in cabled manner. Fig. 2 in particular shows that the electronic computing device 2 is formed for the motor vehicle 1 and comprises at least one electronic circuit 10, which is inactive and operated with a first electrical voltage V1 in a first operating mode of the electronic computing device 2 and which is active and operated with a second voltage V2 in a second operating mode different from the first operating mode, and is formed with a first voltage supply device 11 for providing the first voltage V1.
It is provided that the electronic computing device 2 comprises the supply interface 8 for contacting with the control device 7 external to computing device for the second operating mode, wherein the control device 7 external to computing device is formed for providing the second voltage V2 by means of a separate second voltage supply device 12, wherein
the at least one electronic circuit 10 is formed to be operated with the second voltage V 2 from the control device 7 external to computing device via the supply interface 8.
Thereby, the arrangement 6 according to Fig. 2 in particular solves the problem that for example an internal hardware block of the electronic circuit 10 can be inactive in a normal operation of the electronic computing device 2, in particular in the first operating mode, and still requires a voltage, in particular the first voltage V1, to for example provide improved electromagnetic compatibility of the electronic computing device 2. For example, if a debugging mode as the second operating mode and/or a flashing mode as the second operating mode now have to be performed for the electronic circuit 10, thus, it requires the second voltage V2. The second voltage V2 is now provided externally to computing device such that a second voltage supply device does not have to be provided on the electronic computing device 2. Contacting between the control device 7 external to computing device and the electronic computing device 2 has to be performed in the debugging mode and in the flashing mode, respectively, wherein the second voltage V2 is now provided by the control device 7 external to computing device. Thus, the electronic computing device 2 can be provided reduced in components in the first operating mode since the second voltage V2 is provided by the control device 7 external to computing device.
In particular, it can be provided that the at least one electronic circuit 10 is formed as a microcontroller or as a system on a chip. In other words, complex computing performances can be provided by means of the electronic circuit 10 as a microcontroller and simple computing performances can be performed as a system on a chip, respectively.
In particular, Fig. 2 shows the electronic computing device 2 in the contacted state with the control device 7 external to computing device and thus in the second operating mode.
In particular, it can further be provided that the supply interface 8 additionally comprises a data interface 14 for receiving data from the control device 7 external to computing device. Hereto, the further supply interface 9 can for example comprise a further data interface 15. Thus, it is allowed that both the second voltage V2 and the data itself can be transferred between the control device 7 external to computing device and the electronic computing device 2 by one plugging operation.
Further, it can be provided that the electronic computing device 2 comprises an electrical support circuit 16 for supporting the electronic computing device 2 in the second operating mode. The support circuit 16 can also be termed debugging/flashing support circuit.
The electronic circuit 10 is in particular contacted with an electrical ground 21.
In Fig. 2, it is in particular shown that the electronic computing device 2 comprises a switching element 17, which is formed to switch between the first voltage supply device 11 and the supply interface 8. Thus, in the connected state of the electronic computing device 2 to the control device 7 external to computing device, the switching element 17 is in particular formed in that the electronic circuit 10 is supplied with the second voltage V2. In the shown state, the circuit is in particular opened to the first voltage supply device 11 and closed to the second voltage supply device 12 such that the second voltage V2 is supplied to the electronic circuit 10. Herein, it is in particular also shown that the switching element 17 is formed to perform a switching operation in the contacted state of the control device 7 external to computing device such that the electronic circuit 10 is supplied with the second voltage V2. Hereto, it can in particular be provided that as soon as the second voltage V2 is applied to the switching element 17, this switching element 17 automatically switches. In other words, the connection between the first voltage supply device 11 is automatically disconnected such that the electronic circuit 10 can be operated with the second voltage V2. Thereby, manual intervention by a user is in particular not required.
Fig. 3 shows a block diagram of a further embodiment of the arrangement 6 in a further schematic view. In the form of configuration shown in Fig. 3, the electronic computing device 2 comprises an electrical resistance element 18, which is contacted with the first voltage supply device 11 on a first side 19 of the electrical resistance element 18 and is contacted with at least the supply interface 8 and the at least one electronic circuit 10 on a second side 20 of the electrical resistance element 18. In particular, it is provided that the resistance value of the electrical resistance element 18 is determined depending on a first voltage value of the first voltage V1 and a second voltage value of the second voltage V2. In other words, the resistance value is decidedly adapted to the first voltage V1 and to the second voltage V2 such that upon contacting the control device 7 external to computing device, the electronic circuit 10 is supplied with the correct voltage. In particular, the difference between the first voltage V1 and the second voltage V2 generates a constant current at the electronic resistance element 18.
Therefore, it is in particular provided that the first voltage V1 is different from the second voltage V2, wherein the second voltage V2 is in particular specially designed for the second operating mode. The invention also relates to a method for operating the electronic computing device 2 for the motor vehicle 1 , in which at least the one electronic circuit 10 is inactive and operated with the first electrical voltage V1 in a first operating mode of the electronic computing device 2 and in which the at least one electronic circuit 10 is active and operated with the second voltage V2 in the second operating mode different from the first operating mode, and in which the first voltage V1 is provided by means of the first voltage supply device 11 of the electronic computing device 2.
