Abstract

A method for determining whether an error condition is present in a motor vehicle, a discrete state in which the motor vehicle is momentarily situated being ascertained with the aid of a state machine, monitoring functions for ascertaining whether an error condition is present being carried out or not as a function of the ascertained discrete state.

Claims

1. A method for determining whether an error condition is present in a motor vehicle, the method comprising:

ascertaining a discrete state in which the motor vehicle is currently situated with the aid of a state machine; and

performing monitoring functions for ascertaining whether an error condition is present as a function of the ascertained discrete state.

2. The method of claim 1, wherein monitoring models are activated as a function of the ascertained discrete state, a monitoring function associated with the respective monitoring model being performed for active ones of the monitoring models.

3. The method of claim 2, wherein when a monitoring function ascertains an error, an error response function associated with this monitoring function is performed.

4. The method of claim 1, wherein actual variables, which describe an instantaneous state of the motor vehicle and/or setpoint variables, which describe an intended state of the motor vehicle, are communicated to the monitoring functions.

5. The method of claim 1, wherein monitoring models are activated as a function of the ascertained discrete state, a monitoring function associated with the respective monitoring model being performed for active ones of the monitoring models, wherein actual variables, which describe an instantaneous state of the motor vehicle and/or setpoint variables, which describe an intended state of the motor vehicle, are communicated to the monitoring functions, and wherein the actual variables and/or the setpoint variables are ascertained by a monitoring model.

6. The method of claim 1, wherein information about a spatial position of the motor vehicle is incorporated in the ascertained discrete state.

7. The method of claim 1, wherein the monitoring functions also include discrete monitoring functions, which decide whether an error condition is present or not, depending on the ascertained discrete state of the motor vehicle.

8. A computer readable medium having a computer program, which is executable by a processor, comprising:

a program code arrangement having program code for determining whether an error condition is present in a motor vehicle, by performing the following;

ascertaining a discrete state in which the motor vehicle is currently situated with the aid of a state machine; and

performing monitoring functions for ascertaining whether an error condition is present as a function of the ascertained discrete state.

9. The computer readable medium of claim 8, wherein monitoring models are activated as a function of the ascertained discrete state, a monitoring function associated with the respective monitoring model being performed for active ones of the monitoring models.

10. A control unit for determining whether an error condition is present in a motor vehicle, comprising:

a control arrangement configured to ascertain a discrete state in which the motor vehicle is currently situated with the aid of a state machine, and to perform monitoring functions for ascertaining whether an error condition is present as a function of the ascertained discrete state.
