Abstract: A method for a vehicle, comprising: during a first condition, closing a canister vent valve responsive to an engine-off event without initiating an engine-off natural vacuum test; during a second condition, following the first condition, closing the canister vent valve responsive to a vehicle-off event; and then initiating an engine-off natural vacuum test. In this way, the completion percentage of the engine-off natural vacuum test will increase.

Abstract: Vehicle trajectory data is obtained. A variance of the trajectory data is recursively determined. A speed-dependent weighting function is computed to obtain a speed-dependent weight. An anomaly index is determined based at least on part on application of the speed dependent weight to the recursively determined variance.

Abstract: A vehicle's dynamic handling state, driver inputs to the vehicle, etc. may be examined to determine one or more measures of driver workload. Driver interface tasks may then be delayed and/or prevented from executing based on the driver workload so as to not increase the driver workload. Alternatively, driver interface tasks may be scheduled for execution based on the driver workload and caused to execute according to the schedule, for example, to minimize the impact the executing driver interface tasks have on driver workload.

Abstract: Route planning for road vehicles is performed taking into account a ride quality that results from the roadway conditions along road segments on a route. A plurality of vehicles equipped with controlled suspensions calculate ride quality indices as the vehicles move over a plurality of road segments. The plurality of vehicles transmit the ride quality indices tagged with respective geographic coordinates to an aggregating server. The aggregating server determines a composite ride quality index for each road segment. A subscriber generates a route planning request identifying an origin and a destination. At least one potential route is identified between the origin and the destination comprised of selected road segments. A route ride quality index is determined in response to the selected road segments, and the potential route and the route ride quality index are presented to the subscriber for selection.

Abstract: A driver interface system includes a processor programmed to receive driver interface tasks to be executed and to selectively delay or prevent at least some of the driver interface tasks from being executed based on a driver workload. The driver workload is derived from a variability of an activity level of a driver relative to a mean value of the activity level as represented by a recursively computed determinant of a covariance of the activity level.

Abstract: A vehicle system having at least one sensor configured to output a range signal and a range-rate signal. The range signal represents a distance from a host vehicle to the front vehicle and the range-rate signal represents range-rate information of the front vehicle relative to the host vehicle. A processing device is configured to output a control signal based on the range signal and the range-rate signal. The control signal commands an engine of the host vehicle to start.

Abstract: A visual feedback system for a vehicle including an engine, includes an operating control for varying the engine's speed. Connected to the engine, an engine acceleration reporter reports an amount of acceleration of the engine. A creation control being linked to both the engine acceleration reporter and the operating control enables the creation of images on a visual display according to a variation in the engine speed. Accordingly, the creation control creates a pendulum image within a sector of a circle, with the pendulum image swinging in response to the amount of acceleration being reported by the engine acceleration reporter.

Abstract: A vehicle powertrain controller includes a fuzzy logic-based adaptive algorithm with a learning capability that estimates a driver's long term driving preferences. An adaptive algorithm arbitrates competing requirements for good fuel economy, avoidance of intrusiveness and vehicle drivability. A driver's acceptance or rejection of advisory information may be used to adapt subsequent advisory information to the driving style. Vehicle performance is maintained in accordance with a driver's driving style.
