Phase Plane-based Approaches for Event Detection and Plausibility Check of Vehicle Dynamics

Abstract

In recent years the number of electronic systems dramatically increased in vehicles. In the field of autonomous braking the Electronic Stability Control (ESC) is one of the most important braking functions. Two of the biggest challenges of the development of ESC are the validity of the inputs and logic of the intervention. In this paper the initial results of a new phase plane-based approach are introduced. This approach can be the base of a wide spectrum of vehicle dynamic application but from ESC point of view it can be used for detecting critical driving maneuvers and for monitoring of inertia sensors plausibility. The main advantage of the phase-based method is that it can decrease the number of necessary vehicle dependent parameters during the detection of critical driving situations and sensor plausibility problems. In the article simulation results are presented to highlight the advantage of the proposed approach. The results show that our phase plane method can be used in the development of ESC in the future.
