Abstract: A method for providing a coast recommendation for an operator of a vehicle, including receiving vehicle position data; determining a projected route; determining a first speed change position and a first speed change target speed; determining a first residual speed and a first residual speed position based at least in part on the first speed change position and the first speed change target speed; determining a first lower speed envelope; determining an overall lower speed envelope based at least in part on the first residual speed; determining an upper speed envelope; determining a target speed profile based at least in part on the first residual speed, the first residual speed position, the first lower speed envelope, and the upper speed envelope; determining a coast start point based at least in part on the target speed profile; and communicating the coast start point to the operator of the vehicle.

Abstract: A method for providing a cruising speed recommendation to an operator of a vehicle includes determining a projected route; receiving route characteristic data including route elevation data; determining a sampling resolution; sampling the route elevation data at the sampling resolution to generate sampled route elevation data; determining at least one start of uphill position and at least one start of downhill position; determining at least one cruise speed route segment based at least in part on the at least one start of uphill position and the at least one start of downhill position; determining a corresponding cruising speed for the at least one cruise speed route segment based at least in part on one or more of the route elevation data and the sampled route elevation data; and communicating the corresponding cruising speed for the at least one cruise speed route segment.

Abstract: A system includes an exhaust system fluidly configured to define an exhaust stream. A sensor is arranged in the exhaust system and is configured to be exposed to the exhaust stream and accumulate particulate matter on the sensor. The sensor provides a signal that varies based upon an amount of particulate matter on the sensor. A control system is in communication with the sensor. The control system includes a controller configured to calculate a differential of a conductance signal related to the signal, compare consecutive differentials to identify an erroneous differential in an abnormal signal based upon an anomaly relating to the accumulation of the particulate matter, and reconstruct the abnormal signal by correcting the erroneous differential to produce a corrected, decimated conductance signal. The control system is configured to determine a total accumulated particulate matter adjusted for the anomaly.

Abstract: A method of quantifying a particulate matter in an exhaust stream includes the steps of accumulating a particulate matter on a sensor. The sensor provides a signal that varies based upon an amount of the particulate on the sensor. The sensor includes a measurement cycle that includes a deadband zone, followed by an active zone, which is followed by a regeneration zone. The particulate matter is calculated after an end of the deadband zone is reached and prior to an end of the measurement cycle.
