Abstract
A method for the detection of errors in a motor vehicle, performance characteristics and information for characterizing the performance characteristics being recorded in a motor vehicle over a specific period of time. To make possible a predictive detection of errors in a motor vehicle at a high degree of reliability, a method is proposed having the following steps: From the performance characteristics recorded before the occurrence of a specific error in the motor vehicle, a performance characteristics model is generated, which is assigned to the error. The performance characteristics model is described in an appropriate form (rules and/or mathematical functions), and the currently recorded performance characteristics are compared during the operation of the motor vehicle with the descriptions of the performance characteristics models characterizing the errors.
