A system and method for filtering exhaust gases of a vehicle is disclosed, that are based on an exhaust filter assembly includes an enclosure having an inlet coupled with an end of an exhaust pipe to allow exhaust gases of the vehicle into the enclosure, a filter element fitted with the enclosure to adsorb gaseous particles, moisture, and unburned fuel mist particles of the exhaust gases, sensors to sense gaseous particles adsorbed on the filter element, and generate first signals based on the sensed gaseous particles; a control unit; and a communication unit. The control unit includes processors to: receive the generated first signals, and generate second signals based on the received first signals. The communication is configured to transmit the second signals to computing devices of users to notify the users. Thermoelectric generator is adapted to convert heat energy of the exhaust gases into electric power.

An automobile brake control method comprises: obtaining wheel rotation speed sensor information of an automobile within the current measurement period; and when the wheel rotation speed sensor information satisfies a preset condition, allowing the automobile to enter an aquaplane safety logic control mode, and after an ABS operates, allowing the ABS to exit front axle control and merely control a rear axle so that a driver takes over automobile control, until the next measurement period.

A system for generating a virtual engine sound may include a server having information on at least one review of the virtual engine sound, and a virtual engine sound generator to generate “my sound” by tuning the virtual engine sound based on information on customized design settings, to update a preset driver emotion model for each emotion evaluation area of the virtual engine sound, based on the information on the at least one review of the virtual engine sound, which is received from the server, and to update the virtual engine sound based on the “my sound” and the driver emotion model updated for each emotion evaluation area.

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 vehicle device may receive audio data and other vehicle data associated with a vehicle and may transform the audio data to transformed audio data in a frequency domain. The vehicle device may segment the transformed audio data into a plurality of audio segments and may process the plurality of audio segments, with different feature extraction techniques, to extract a plurality of feature vectors. The vehicle device may merge the plurality of feature vectors into a merged feature vector and may create an audio signature for the audio data based on the merged feature vector. The vehicle device may process the audio signature and the other vehicle data, with a model, to determine a classification of the audio signature and may perform one or more actions based on the classification of the audio signature.

A method for activating at least one device from a transportation vehicle wherein the at least one device is activated by the transportation vehicle at least as a function of global position data of at least one pedestrian and/or at least one cyclist. The position data of the at least one pedestrian and/or the at least one cyclist is transmitted to a remotely located computer unit and is made available to a computer unit of the transportation vehicle. The activation of the at least one device as a function of the position data of pedestrians and/or cyclists is made possible in a simple and economic way.

Various examples are directed to systems and method operating an autonomous vehicle. A vehicle system may receive a plurality of inputs from a user of a vehicle, where the plurality of inputs includes a first labeling input received from the user and a first alert input received from the user. After determining that no user input has been received for an input threshold time, the vehicle system provides an alert prompt to the cockpit output device. This may cause the cockpit output device to provide the alert prompt to signal to the user to provide an alert input indicating that the user is alert.
