Abstract

A method for entering data into at least a first and a second control device of a motor vehicle is provided. Each of the first and the second control device is provided with a sequencing control that has a reversible deactivation state, a programming mode, and an operating mode with operating functions. The first and the second control device are each put into the deactivation state, during which the execution of operating functions of the operating mode is prevented, preferably at least to a large extent. The first and the second control device are each put into the programming mode, during which the reversible deactivation state of each control device is maintained. The deactivation state of all control devices will be canceled after the respective data have been entered into all control devices in the programming mode.

Claims

1. A method for entering data into at least a first control device and a second control device of a motor vehicle, the method comprising the acts of:

providing each of the first control device and the second control device with a sequencing control that has a reversible deactivation state, a programming mode, and an operating mode with operating functions;

putting each of the first control device and the second control device into the deactivation state, during which execution of at least some of the operating functions of the operating mode is prevented;

putting each of the first control device and the second control device into the programming mode, while maintaining the deactivation state of each of the first control device and the second control device; and

terminating the deactivation state of all control devices after respective data have been entered into all control devices in the programming mode.

2. The method according to claim 1, wherein a control device that is in the deactivation state remains in the deactivation state after a restarting of the control device.

3. The method according to claim 2, wherein the restarting of the control device is an unintentional restarting due to a voltage loss.

4. The method according to claim 1, wherein at least one of the operating functions of automatic error storage, emission of messages, or emergency running function is switched off in the deactivation state.

5. The method according to claim 1, wherein during the programming mode, each of the first control device and the second control device is provided with new data or with a completely or partially new sequencing control, which are stored in at least one reprogrammable storage area of the respective control device.

6. The method according to claim 1, wherein after the programming of all of the control devices, each of the first control device and the second control device is put into its operating mode.

7. The method according to claim 6, wherein after the programming of all of the control devices, the deactivation state of the first control device and the second control device is cancelled.

8. The method according to claim 1, wherein the first control device and the second control device are put into the reversible deactivation state, the programming mode, or the operating mode by a diagnostic device in a vehicle shop.

9. The method according to claim 8, wherein the diagnostic device is a control device tester.

10. The method according to claim 8, wherein the first control device and the second control device are put into the reversible deactivation state, the programming mode, or the operating mode after an authorization check.

11. A vehicle comprising:

an on-board network comprising at least a first control device and a second control device, wherein data or sequencing controls are entered into the first control device and the second control device by;

providing each of the first control device and the second control device with a sequencing control that has a reversible deactivation state, a programming mode, and an operating mode with operating functions;

putting each of the first control device and the second control device into the deactivation state, during which execution of at least some of the operating functions of the operating mode is prevented;

putting each of the first control device and the second control device into the programming mode, while maintaining the deactivation state of each of the first control device and the second control device; and

terminating the deactivation state of all control devices after respective data have been entered into all control devices in the programming mode.

12. A control device in an on-board network of a vehicle, wherein data or sequencing controls are entered into the control device by:

providing each of the first control device and the second control device with a sequencing control that has a reversible deactivation state, a programming mode, and an operating mode with operating functions;

putting each of the first control device and the second control device into the deactivation state, during which execution of at least some of the operating functions of the operating mode is prevented;

putting each of the first control device and the second control device into the programming mode, while maintaining the deactivation state of each of the first control device and the second control device; and

terminating the deactivation state of all control devices after respective data have been entered into all control devices in the programming mode.

13. A diagnostic device for control devices of an on-board network of a motor vehicle, wherein the diagnostic device enters data or sequencing controls into at least a first control device and a second control device of the vehicle by:

providing each of the first control device and the second control device with a sequencing control that has a reversible deactivation state, a programming mode, and an operating mode with operating functions;

putting each of the first control device and the second control device into the deactivation state, during which execution of at least some of the operating functions of the operating mode is prevented;

putting each of the first control device and the second control device into the programming mode, while maintaining the deactivation state of each of the first control device and the second control device; and

terminating the deactivation state of all control devices after respective data have been entered into all control devices in the programming mode.
