Abstract: A method mitigates an unintended lateral motion (ULM) event of a motor vehicle having a powertrain system with multiple propulsion actuators. The method, which may be recorded on a computer readable storage medium and executed therefrom by a processor, includes identifying, via an electronic controller of the motor vehicle, a present dynamic operating region at an onset of the ULM event as a linear or non-linear operating region. Lateral motion includes lateral acceleration and/or lateral yaw of the motor vehicle. The method also includes determining whether the lateral motion exceeds calibrated lateral dynamic limits for the particular operating region, and executing a powertrain control action in different manners depending on whether the ULM event occurs in the non-linear or linear operating region. The powertrain control action includes changing a dynamic speed state of at least one of the propulsion actuators.

Abstract: A method of analyzing vehicle parameters to distinguish between whether an unexpected vehicle acceleration is due to an internal fault or external forces. The method uses a magnitude and direction of a change in acceleration for evaluating whether the unexpected acceleration is due to a potential system fault scenario or a potential crash scenario.
