摘要： A method for determining intake air mass into the engine includes equipping an air intake system with an air meter system configured to generate a signal output having a cycle period correlatable to an intake air mass. The signal output from the air meter system is monitored during an event, and successive cycle periods of the signal output from the air meter system are determined. Intake air mass for each of the successive cycle periods is determined and integrated.

摘要： An internal combustion engine includes an engine block defining at least one cylinder therein. A cylinder head is attached to the engine block and defines a combustion chamber with the at least one cylinder in the engine block. A piston is disposed within the at least one cylinder. A glow plug is disposed within the combustion chamber. A resistance of the glow plug is detected and an estimated combustion temperature is determined based upon the detected resistance of the glow plug. The engine is then controlled based upon the estimated combustion temperature established from the glow plug resistance.

摘要： A system for determining the position of a rotating wheel using RFID. In one embodiment, the system includes a position sensing wheel mounted to one or both of a crankshaft and a camshaft in the engine. A plurality of RFID tags are disposed at predetermined intervals around the wheel, and an RFID transceiver is positioned proximate the wheel. As the wheel rotates, the RFID transceiver transmits a signal that interrogates the RFID tags, which then transmit a coded signal to the transceiver identifying the wheel's position relative to the transceiver. Therefore, regardless of the position of the wheel, the RFID transceiver can interrogate the closest RFID tag and immediately know the position of the engine so that an engine controller can provide fuel and spark to the cylinders as soon as possible.

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： An engine system of a vehicle includes an engine torque module. The engine torque module determines an engine output torque profile including predicted torque outputs based on an accelerator signal and an engine state variable. A load control module determines a dynamic transmission load profile based on the engine output torque profile and an engine speed profile. The dynamic transmission load profile includes transmission loads as a function of engine speed during an auto-start of an engine. A compensation module generates a torque compensation signal based on the dynamic transmission load profile. An actuator module compensates for a change in a transmission load based on the torque compensation signal and during a transition of the engine from a cranking state to an idle state.

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.
