Creation of driving cycles with lateral and longitudinal dynamics for analyzing energy losses in chassis

The naturalistic driver behavior has an influence on many types of energy losses in chassis systems. Therefore it is important to know for analyzing methods to improve the energy efficiency. It is possible to record the usage of cars on different roads. It is necessary to post-process this data for investigations.This paper presents a method for generating driving cycles including longitudinal and lateral dynamics. Both cannot be neglected for chassis based energy losses. In contrast to the literature, the method is vehicle-independent, since it uses yaw rate and velocity.Driving cycles are generated using the Markov chain stochastic method and are evaluated with regard to their representativeness of the database using a quality criteria. This is composed of different values describing longitudinal and lateral dynamics. The validity is demonstrated through simulations of an extended two-track model.
