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.

Abstract: A method of estimating the individual fuel air ratio richness of an individual cylinder in an engine by utilizing a single oxygen sensor at the confluence of a plurality of exhaust runners. The method provides for the use of a wide range or switching oxygen sensor at the confluence of a plurality of exhaust runners.

Abstract: A skip shift device performance detecting method used to more accurately enable skip shift diagnostic execution in a manual transmission equipped vehicle where a skip shift has been requested and a transmission clutch remains engaged. Where a skip shift request ceases during clutch engagement, a timed loop is used to monitor if clutch disengagement occurs before the loop times out. Where clutch disengagement occurs before the loop times out, skip shift diagnostic execution is enabled. Where the loop times out before disengagement, skip shift diagnostic execution is disabled. Where the skip shift is requested and the clutch remains engaged, the skip shift request is monitored to determine whether it is withdrawn before clutch disengagement. If it is withdrawn before clutch disengagement, the aforementioned timed monitoring loop is executed. If it is not withdrawn before clutch disengagement, execution of the skip shift diagnostic is enabled.
