A system for monitoring the emissions performance of a vehicle by scanning an OBD system of the vehicle and transmitting the information to a hub. A determination is made whether the engine of the vehicle is in a non-compliant state. The non-compliant state including a failure of an oxygen sensor that causes a hub to control a refueling dispenser that presents a message confirming that the vehicle is in the non-compliant state on a display at the refueling dispenser and automatically levies a fine against the owner of the vehicle for being in the non-complaint state when the user or owner pays to refuel their vehicle. The fine is remitted to the regulating authorities.

A misfire detecting system for an engine of a vehicle that detects a misfire of the engine is provided, which includes a processor. The processor determines whether a misfire has occurred by examining whether a fluctuation of a crank angle of the engine is equal to or greater than a determination reference value, acquires a value relating to a density of intake air introduced into the engine, and adjusts the determination reference value according to the value related to the density.

An exhaust system is provided that includes an exhaust aftertreatment unit, first and second exhaust pathway in communication with and upstream of the exhaust aftertreatment unit, a thermally activated flow control device operable in a first and second mode, and a thermal storage device. In the first mode, the flow control device permits exhaust to flow to the aftertreatment unit through the first pathway and inhibits flow through the second pathway. In the second mode, the flow control device permits exhaust flow to the aftertreatment unit through the second pathway and inhibits flow through the first pathway. The flow control device may switch between the first and second modes based on a change of temperature. The thermal storage device is within the second pathway, stores thermal mass, and provides thermal insulation to enable a catalyst of the aftertreatment unit to maintain a predetermined temperature for a predetermined time.

Methods and systems are provided for a diagnostic of a humidity sensor positioned in an intake of an engine and adjusting engine operation responsive to findings of the diagnostic. In one example, the method may include sealing a vehicle exhaust system of an engine, combusting fuel at cylinders of the engine while flowing gases through the engine in a first direction, and then, flowing the combusted exhaust gases through the engine in a reverse, second direction to the humidity sensor positioned in the intake. The method may further include indicating degradation of the humidity sensor based on the output of the humidity sensor while flowing gases in the first and second directions.

A control system of a vehicle has an automatic stop and restart function to automatically stop an engine when automatic stop conditions are fulfilled, and restart the engine when normal restart conditions are fulfilled during automatic stop of the engine, and a notifying function to notify a driver of starting of a preceding vehicle, when an intervehicular distance from the preceding vehicle during stopping becomes equal to or larger than a first predetermined distance. The automatic stop and restart function includes a synchronous restart function of restarting the engine, in synchronization with notification by the notifying function, even when the normal restart conditions are not fulfilled. When notification fixation is detected, the synchronous restart function is restricted, and restart of the engine is inhibited until the normal restart conditions are fulfilled.

A system including a vehicle control unit configured to detect a vehicle event and a communication unit configured to transmit a notification from the vehicle control unit to a mobile device, the notification including both an identification of the vehicle event and instructions on how to enact a specific driving task to reverse a condition associated with the detected event.

A process for measuring methane emissions by an internal combustion engine includes connecting a methane sensor to an exhaust line of the internal combustion engine such that a portion of the gas in the exhaust line can enter the methane sensor, operating the internal combustion engine so as to produce the exhaust, measuring a methane concentration of the gas from the portion of the gas from the exhaust line with the methane sensor, and producing an output from the methane sensor corresponding to the methane concentration. The methane sensor is plumbed to the exhaust line. The methane concentration is continuously sampled by the methane sensor. The methane sensor can be an electrochemical cell, a catalytic methane sensor, or an infrared methane sensor.

A fuel tank containing a fuel and oil mixture is managed to determine if the fuel and oil mixture contains the correct ratio for a motor. The fuel tank containing a fuel and oil mixture is monitored. A fuel to oil ratio is selected for the motor. A combined viscosity of the fuel and oil mixture is calculated with respect to the fuel to oil ratio, and the temperature of the fuel and oil mixture. The combined viscosity is used to determine a predetermined range of the combined viscosity. The viscosity of the fuel and oil mixture within the fuel tank is measured as a measured viscosity. If the measured viscosity of the fuel and oil mixture does not correspond with the predetermined range, then a user may be alerted that the measured viscosity does not correspond with the predetermined range.

A system for managing noise, vibration and harshness (NVH) based on floor vibration for a vehicle, may include a vibration sensor, which is disposed on a floor of a vehicle and detects a vibration value; and a control module, which controls an operation of a vibration generating device of the vehicle in response to the vibration value detected by the vibration sensor, wherein when the vibration value detected by the vibration sensor exceeds a predetermined first threshold value, the control module decreases the vibration by adjusting a driving parameter of the vibration generating device of the vehicle.
