Analysis of active toe-in for vehicle longitudinal dynamics

摘要

A wheel-individual steering system allows influencing the toe-in actively. This possibility can be used to interfere with the longitudinal dynamics of a vehicle. Thus a potential for a functional integration of braking and steering arises, which has to be analyzed. In this paper, an active toe-in for generating braking forces is examined with the help of simulation and the potential is discussed. It also shows an approach how the lateral behavior of vehicle tires can be determined experimentally with measurements of the vehicle longitudinal dynamics. A verification of this approach is done with a testbed of the Mechatronic-Mobile.
