摘要： An engine system includes a first module that determines a cylinder of an engine to be in one of M prediction types and generates a distance from intake signal indicating a number of prediction steps the cylinder is away from an intake stroke. M is an integer greater than or equal to 3. A second module determines a cycle type of the cylinder. The cycle type indicates a number of combustion cycles the cylinder has experienced from a last restart of the engine. A cylinder air charge module estimates an air mass within the cylinder based on the distance from intake signal and the cycle type.

摘要： An engine control system for an auto-stop/start vehicle includes a mode control module and an actuator control module. The mode control module selectively initiates an engine startup event when an engine startup command is generated. The actuator control module cranks an engine during the engine startup event, provides fuel to a first cylinder of the engine while the engine is being cranked, and selectively disables fuel to a second cylinder of the engine while the engine is being cranked. The second cylinder is after the first cylinder in a firing order.

摘要： A system includes a transceiver module and a rotating device. The transceiver module generates an electromagnetic (EM) field using an antenna. The rotating device includes N transponders arranged such that each of the N transponders passes through the EM field during one revolution of the rotating device. Each of the N transponders damps the EM field when passing through the EM field. The transceiver module determines a rotational speed of the rotating device based on a number of times the EM field is damped during a period. N is an integer greater than or equal to 1.
