Abstract: A system includes a processor configured to receive a set of user attribute preferences for a trip. The processor is also configured to determine a plurality of trip routes, the routes having variance in a value for at least one user attribute preference as compared to other of the routes. The processor is further configured to present the plurality of routes in a selectable manner, including displaying an attribute value associated with each route and implement navigation for a selected route.

Abstract: Methods and systems are provided for reliably providing a prognosis of the life-expectancy of a vehicle battery. A state of degradation of the battery is predicted based on a rate of convergence of a metric, that is derived from a sensed vehicle operating parameter, towards a defined threshold, determined based on past history of the metric. The predicted state of degradation is then converted into an estimate of time or distance remaining before the component needs to serviced, and displayed to the vehicle operator. Vehicle control and communication strategies may be defined with respect to the predicted state of degradation.

Abstract: A system includes a processor configured to receive report of a vehicle part malfunction, along with vehicle travel history covering at least a predefined time period. The processor is also configured to obtain condition data relating to environmental conditions encountered by the vehicle during the travel history. The processor is further configured to compare the obtained condition data to other condition data obtained from other vehicles reporting the same part malfunction. And the processor is configured to create a malfunction likelihood record for the vehicle part, including an association with a condition occurring over a threshold percentage of times with regards to all obtained condition data relating to the part malfunction and an indicator of a likely failure when a vehicle encounters the condition.

Abstract: Methods and systems are provided for diagnosing a shock absorber coupled to a vehicle tire. In one example, a sensor of a tire pressure measurement system coupled inside a tire is used to measure a tire pressure as well as an oscillatory behavior of the tire. A state of health of a shock absorber coupled to the tire is estimated based on the oscillatory behavior.

Abstract: A system includes a computer including a processor and a memory, the memory storing instructions executable by the processor to identify a wheel having a force imbalance based on wheel speed data from each of a plurality of vehicle wheels, and to identify a wheel force imbalance fault when the force imbalance exceeds at least one of a distance threshold and a time threshold.

Abstract: A computer determines that a rate of travel value for a route segment being traversed by a first vehicle exceeds a predetermined threshold. A maneuver is planned for the first vehicle to depart from the route segment based on collected vehicle operating data from one or more second vehicles previously traversing the route segment. The first vehicle is instructed to execute the maneuver to depart the route segment.

Abstract: Methods and systems are provided for reliably prognosing a vehicle component, such as a vehicle battery or an intake air filter. A state of degradation of the component is recursively predicted by updating, based on a sensed vehicle operating parameter, a previously estimated state of degradation of the component, the parameter selected based on the component being diagnosed, as well as based on past driving history and future driving predictions. The predicted state of degradation is then converted into an estimate of time or distance remaining before the component needs to serviced, and displayed to the vehicle operator.

Abstract: Methods and systems are provided for determining condition of an air filter coupled to an intake passage of an engine system. In one example, a method may include estimating a resistance of the air filter based on a manifold air charge value. The manifold air charge value may be either a mass air flow or a manifold air pressure.
