A vehicle control device includes a storage device that stores mapping data including data that defines mapping that receives input data based on a plurality of detection values which are detection values of an in-vehicle sensor and which are before or after in time series and outputs a predetermined output value and that is learned by machine learning and an execution device that executes an acquisition process of acquiring the input data from the storage device, a calculation process of calculating the predetermined output value with the input data as an input of the mapping, and a transmission process of transmitting the detection values used when the input data is generated and time series data including data based on one or a plurality of detection values which are before or after the detection value used for the input data in time series to an outside of the vehicle.

The embodiment relates to a method for detecting a power-changing manipulation of an internal combustion engine (100), wherein the internal combustion engine (100) has an intake tract (110) and a pressure sensor (116, 118) which is arranged in the intake tract (110). The method has the following steps: acquiring a signal profile (440) over a specific time period by means of the pressure sensor (116, 118), providing a modelled signal profile (430) over the specific time period, from which periodically repeating modelled signal profile sections (432) which are characteristic of expected periodically repeating pressure changes in the intake tract (110) are ascertained, comparing a signal portion of an acquired signal profile section (442) with the corresponding signal portion of the corresponding modelled signal profile section (432) in order to detect the power-changing manipulation of the internal combustion engine (100).

New and/or alternative approaches to physical plant performance control that can account for the health of the physical plant. A physical plant may be controlled by configurable controller, which may further comprise a low level controller associated with a higher level controller such as an Engine Control Unit (ECU). The ECU uses modeling to calculate an estimated operating value of a first parameter in the physical plant, and also uses a sensor to measure an operating value of the first parameter. The measured and modeled values are compared to determine the state of health (SOH) of the physical plant or a component thereof. The SOH may be stored, transmitted, or used to modify one or more control values used by the low level controller.

Embodiments of methods and systems related to operating a mobile asset are provided. In one example, a method for operating a mobile asset includes adjusting a fuel combustion ratio of a plurality of mobile assets based on an emission type exceeding a corresponding threshold, wherein the fuel combustion ratio includes a plurality of fuel types.

An interface circuit assembly for use with an electronic control unit and oxygen sensor of an internal combustion engine. The assembly includes an input port coupled to receive a signal from the oxygen sensor and a processing unit coupled with the input port.

The present disclosure generally relates to a computer implemented method for controlling an exhaust gas aftertreatment system (EATS), specifically applying a scheme for preventing heat reduction at the EATS based on the estimated heat reduction. The present disclosure also relates to a corresponding exhaust gas aftertreatment system (EATS) and a computer program product.

An ENG-ECU performs a specific cylinder fuel cutoff process of stopping combustion of an air-fuel mixture in some cylinders out of a plurality of cylinders of an internal combustion engine and a transmission process of transmitting engine operation information on execution of the specific cylinder fuel cutoff process to an HV-ECU. The HV-ECU performs a torque compensation process of compensating for a decrease in engine torque due to execution of the specific cylinder fuel cutoff process using an output torque of a second MG based on the received engine operation information. The ENG-ECU performs a process of starting the specific cylinder fuel cutoff process in a combustion cycle when a waiting time which includes a time until the HV-ECU receives the engine operation information has elapsed after the transmission process has been performed.
