Abstract: A host vehicle includes a combustion engine configured to provide a propulsion torque to satisfy a propulsion demand. The vehicle also includes at least one sensor configured to detect a position of a reference vehicle. A vehicle controller is programmed to determine a path between a current host vehicle location and an upcoming intersection. The controller is also programmed to forecast a path clearance time at which the host vehicle is able to traverse the intersection in response to sensor data indicating the reference vehicle moving within the path ahead of the host vehicle. The controller is further programmed to deactivate the engine prior to a host vehicle stop based on the path clearance time being greater than a time threshold.
Abstract: A method for determining a liquid level of a reservoir includes sensing a plurality of liquid level points during a plurality of defined computation intervals, and determining filtered block points from the sensed liquid level points occurring during each of the computation intervals. The method fits a regression model to the determined filtered block points, including determining a slope and a standard error of regression, and determines an actual liquid level change from the slope of the regression model. The method may also include making a diagnostic determination if the method determines that a confidence ratio is sufficiently high.

Abstract: A perception module of a spatial monitoring system to monitor and characterize a spatial environment proximal to an autonomous vehicle is described. A method for evaluating the perception module includes capturing and storing a plurality of frames of data associated with a driving scenario for the autonomous vehicle, and executing the perception module to determine an actual spatial environment for the driving scenario, wherein the actual spatial environment for the driving scenario is stored in the controller. The perception module is executed to determine an estimated spatial environment for the driving scenario based upon the stored frames of data associated with the driving scenario, and the estimated spatial environment is compared to the actual spatial environment for the driving scenario. A first performance index for the perception module is determined based upon the comparing, and a fault can be detected.
