A method and system for engine monitoring comprises a monitoring device and a remote device that are in communication. The monitoring device is incorporated in or directly attached to the internal combustion engine and functions to sense a characteristic of the internal combustion engine. The monitoring device is configured to transmit data representative of the sensed characteristic to a remote application running on a remote device. The remote device is configure to produce engine monitoring data from the transmitted data using engine characterising data stored on the remote device.

A method for determining the position of a motor-vehicle crankshaft with a rotating target wheel including markers distributed uniformly over its periphery and a signature, and a sensor sending an electrical signal with edges that appear during the passage of a marker or of the signature before the sensor, including: determining detection time of an edge; determining detection time and computing time difference between estimation and determination; determining angular error; determining presence of an abnormal edge when the angular error exceeds a threshold and storing the associated marker number in a first error list; when the signature passes, copying the first error list to the second if it does not exist; adjusting an occurrence counter depending on the error list; and if the errors are not transient, correcting edges with marker numbers in memory in the second error list, then sending a crankshaft position signal depending on the signal.

A sensing system and method utilizes measured flywheel speed variations to determine engine torque. The measured engine torque can be used to control vehicle transmissions, clutches, and other vehicle components and systems.

The system is provided to calibrate the ECU of the vehicle. The system comprises a remote computer, a central server, a local computer and setup comprising at least a dynamo meter, and at least one actuator. The dynamo meter and the actuator are interfaced and operated with the local computer. The central server is connected to the local computer by a second networking means, and a remote computer is connected to the central server by a first networking means. The remote computer, uploads instructions to the central server, executes the instructions through the local computer to operate the dynamo meter and the actuator, and calibrates the ECU of the vehicle. The instructions are downloaded to the local computer by the second networking means.

A method is provided for ascertaining a torque curve of a hybrid powertrain including a first sub-powertrain an internal combustion engine, and a second sub-powertrain, which is separated from the first sub-powertrain by a torsional elasticity and has an electric machine with a rotor (10). A rotational characteristic value of the first sub-powertrain is detected via a sensor arranged on the torsional elasticity. A rotational characteristic value of the rotor is detected via a device engaged with the rotor. An irregularity in operation of the internal combustion engine is determined based on at least one of the rotational characteristic value of the first sub-powertrain or the rotational characteristic value of the rotor. The electric machine is controlled based on the irregularity m operation.

A method for estimating at least one ring-related parameter related to at least one piston ring may include estimating a bore distortion of a cylinder bore. The bore distortion may include a plurality of bore distortions corresponding to a plurality of respective piston locations within the cylinder bore. The method may also include receiving the bore distortion in a ring performance model configured to dynamically estimate a plurality of ring-related parameters associated with combustion in the cylinder bore during operation of the internal combustion engine. The ring performance model may be configured to receive a static data signal indicative of static parameters and a dynamic data signal indicative of dynamic parameters related to operation of the internal combustion engine. The ring performance model may be configured to estimate at least one ring-related parameter related to at least one piston ring during operation of the internal combustion engine.

Systems and methods for determining, using service component authenticity detection contained in a sensor module, whether an authorized or genuine service component element is installed in an automotive system are described. The authorized service component determination may be based on close-range communication technology such as radio frequency identification (“RFID”) technology. An antenna in the sensor module may read the tag information from installed service component elements in a nearby service component and send any detected information into a filtration monitoring system. The filtration monitoring system or a remote diagnostic system analyzes the returned data (or absence thereof) to determine if a genuine (i.e., authorized, OEM approved, etc.) service component element is installed or not.
