Abstract

A method for initiating an operation under emergency conditions of a motor vehicle, the method including detecting a malfunction of a component of the motor vehicle; checking whether an operation under emergency conditions is possible; reporting the malfunction to the driver; initiating the operation under emergency conditions under predefined conditions, the operation under emergency conditions being initiated following an active confirmation by the driver.

Claims

1. A method for initiating an operation under emergency conditions of a motor vehicle, comprising:

detecting a malfunction of a component of the motor vehicle;

checking whether an operation under emergency conditions is possible;

determining a risk value of the operation under emergency conditions on the basis of at least one of;

i) a probability of a dangerous situation, and ii) a controllability of the situation by the driver;

reporting the malfunction to the driver; and

initiating the operation under emergency conditions under predefined conditions as a function of the determined risk value, the operation under emergency conditions being initiated following an active confirmation by the driver.

2. The method as recited in claim 1, wherein the risk value is indicated to the driver.

3. The method as recited in claim 1, wherein the predefined conditions depend on the type of malfunction.

4. The method as recited in claim 1, wherein the predefined conditions for the operation under emergency conditions are displayed to the driver.

5. The method as recited in claim 1, wherein at least one physical parameter of a motor vehicle component is restricted in an operation under emergency conditions.

6. The method as recited in claim 1, wherein the driver is warned of the dangerous situation in an operation under emergency conditions.

7. The method as recited in claim 1, wherein, in an operation under emergency conditions, the driver is warned as to which function of the motor vehicle is usable with restrictions.

8. The method as recited in claim 1, wherein the confirmation by the driver takes place by a predefined confirmation sequence of an operating unit.

9. A device for initiating an operation under emergency conditions of a motor vehicle having a control unit, the control unit designed to detect a malfunction of a component of the motor vehicle, to check whether an operation under emergency conditions is possible, to determine a risk value of the operation under emergency conditions on the basis of at least one of:

i) a probability of a dangerous situation, and ii) a controllability of the situation by the driver, to report the malfunction to the driver, and to initiate the operation under emergency conditions under predefined conditions as a function of the determined risk value, the operation under emergency conditions being initiated following an active confirmation by the driver.
