A method of generating vehicle control data is provided. The method is executed using a processor and a storage device and includes: storing first data that prescribe a relationship between a state of a vehicle and an action variable that indicates an action related to an operation of an electronic device; acquiring a detection value from a sensor that detects the state of the vehicle; operating the electronic device; calculating a reward, on the basis of the acquired detection value; in a case where a predetermined condition is met, updating the first data using, as inputs to update mapping determined in advance, the state of the vehicle, a value of the action variable, and the reward; and in a case where the state of the vehicle does not meet the predetermined condition, obtaining second data by adapting the relationship between the state of the vehicle and the action variable.

A method and arrangement for ascertaining an amount of substance emitted as a result of the operation of a functional unit of a vehicle includes transmitting signals from a signal source, which are generated independently of the amount of substance to be ascertained, as input data, to a data processing apparatus. The data processing apparatus contains at least one neural network as a trained model for processing the input data. The method includes generating output data representing the emitted amount of substance in the data processing apparatus using the at least one neural network.

The present invention makes it possible to provide temperature traceability for a test vehicle. A vehicle control device controls temperature information for a test vehicle and includes a peripheral temperature acquisition unit that acquires a peripheral temperature of a test vehicle from a first temperature sensor that is provided in a soak chamber where the test vehicle is stored or in a test chamber where the test vehicle is tested, a position information acquisition unit that acquires position information for the test vehicle, and a recording unit that associates the peripheral temperature of the test vehicle with the position information for that test vehicle and records the association.

This invention relates to exhaust replication systems and methods, such as systems for testing automotive exhaust aftertreatment devices. More particularly, methods for steady state and transient generation and flow of NO.sub.2 and/or NO from a fluid such as nitric acid for introduction into the burner-based exhaust replication system.

A method for diagnosing the dynamics of a sensor in the fresh air or exhaust gas tract of internal combustion engines, as well as a computer program, a computer program product and a corresponding vehicle. It is provided that a corresponding sensor for measuring a pressure signal in the fresh air or exhaust gas tract of an internal combustion engine of a vehicle, which is coupled with a control and computing unit, is checked with respect to its dynamic characteristics. Measured values of differing frequency ranges are measured, these being used as the basis for a calculation of a characteristic. After the calculation, the characteristic is compared with a threshold value stored in a user-defined manner in the control and computing unit. If the calculated characteristic deviates from the threshold value, at least one triggering signal is triggered, so that an impaired sensor dynamic of the sensor is displayed.

A reduction device includes a housing defining an input chamber configured to receive exhaust from a power source, an output chamber, an exhaust channel configured to direct the exhaust from the input chamber to the output chamber, and a longitudinal axis. The reduction device also includes a treatment unit disposed in the exhaust channel and along the longitudinal axis. The treatment unit is configured to at least partly remove pollutant species from the exhaust. The reduction device also includes an attenuation component disposed in the housing and radially outward of the treatment unit. The attenuation component is fluidly connected to the exhaust channel, and is configured to attenuate a range of frequencies corresponding to operation of the power source. Additionally, the exhaust channel prohibits exhaust entering the input chamber from exiting the housing without passing through the treatment unit.

A method of using a burner-based exhaust replication system to generate exhaust that contains nitrogen dioxide (NO.sub.2). An example of such as system is a system used to test automotive exhaust aftertreatment devices. A fluid that decomposes to generate NO.sub.2 as one of its decomposition products is selected. The fluid is heated thereby generating NO.sub.2, with the amount and duration of heating is controlled to result in a desired decomposition extent of NO.sub.2 from the fluid. The fluid is then delivered to an exhaust stream of the system.

An exemplary embodiment may include a control hub configured to receive data from an emissions analyzer and a leak detection camera. The emissions analyzer may detect levels of various gases and relay such information to the control hub. In an exemplary embodiment, the emissions analyzer may purge after every test to ensure longevity and accuracy. A leak detection camera may implement quantifying optical gas imaging in order to continuously monitor for fugitive leaks on a compressor package. If a leak is detected, it may be logged and the user or an operating group may be alerted.

An air monitoring system measures tan amount of pollutant in the air. The system includes a plurality of air quality sensor devices arranged within a selected area. Each of the air quality sensor devices is configured to measure air pollutant levels in the selected area, and includes at least one sensor operatively coupled to a controller, wherein the controller is configured to receive a measured input from the at least one sensor. A wireless communication device is coupled to the controller, and is configured to communicate with a central server device.

This collectively manages an operation rate of multiple test facilities, and is an operation rate analysis system that is communicably connected to multiple test facilities that test a specimen as being a vehicle or a part of the vehicle and that analyzes an operation rate of the above-mentioned multiple test facilities, and that comprises an operation information obtaining part that obtains operation information of the above-mentioned multiple test facilities, a setting receiving part that receives a user setting relating to an operation judgment condition to judge whether each of the multiple test facilities is in operation or not, and an operation rate calculating part that calculates the operation rate of each of the multiple test facilities or the operation rate of all of the multiple test facilities from the operation information obtained by the operation information obtaining part based on the operation judgment condition received by the setting receiving part.
