Component e.g. power engine, functionality testing method for drive train of motor vehicle, involves concluding malfunctioning in drive train of vehicle if measured longitudinal acceleration differs from calculated longitudinal acceleration

摘要

The method involves calculating a longitudinal acceleration of a motor vehicle on a basis of a drive train model. A positively adjusting longitudinal acceleration of the motor vehicle is measured with the help of a longitudinal acceleration sensor. The measured positively adjusting longitudinal acceleration is compared with the calculated longitudinal acceleration. A malfunctioning in the drive train of the motor vehicle is concluded if the measured positively adjusting longitudinal acceleration differs from the calculated longitudinal acceleration.
