摘要： A system includes a processor configured to detect a vehicle condition associated with a warning light. The processor is also configured to obtain explanatory information explaining the cause of the warning light. The processor is further configured to present the explanatory information via a vehicle display. Also, the processor is configured to present a plurality of options for further action with the explanatory information and, upon selection of one of the options, take further steps in accordance with the selection option.

摘要： A vehicle comprises: a dispenser for a liquid, the dispenser comprising an outlet for the liquid; and a source of ultraviolet light disposed to emit the ultraviolet light onto the outlet of the dispenser. The dispenser further comprises a first position and a second position that is different than the first position. The outlet of the dispenser is disposed closer to the source of ultraviolet light when the dispenser is in the second position than when the dispenser is in the first position. The vehicle comprises a controller in communication with the source of the ultraviolet light. The controller causes the source of ultraviolet light to emit the ultraviolet light when the dispenser is in the second position but not when the dispenser is in the first position.

摘要： Methods and systems are provided for controlling airflow of an accumulator of a motorized vehicle. In one example, a method includes storing pressurized gases within the accumulator by flowing intake air from a compressor of an engine of the vehicle to a pressure booster arranged upstream of the accumulator. Pressurized gases stored within the accumulator may be used to drive one or more pneumatic devices.

摘要： Methods and systems are provided for detecting cylinder-to-cylinder air-fuel ratio (AFR) imbalance in engine cylinders. In one example, a method may include detecting an AFR imbalance of an engine cylinder based on an individual crankshaft acceleration of the cylinder relative to a mean crankshaft acceleration produced by all cylinders of the engine, and correcting a fuel amount of the cylinder via a fuel multiplier value, the fuel multiplier value selected from a plurality of fuel multiplier values based on an imbalance source. In this way, the AFR imbalance may be accurately detected and correcting using existing engine system sensors.

摘要： Methods and systems are provided for improving efficiency of an exhaust gas after treatment system of a vehicle. In one example, a first group of engine cylinders is operated with a rich air-fuel ratio continuously while a second group of engine cylinders is operated with a lean air-fuel ratio continuously. The rich and lean exhaust gases from the two groups of engine cylinders may be oxidized within an exhaust gas after treatment system to improve catalyst efficiency.

摘要： Methods and systems are provided for identifying degraded exhaust gas temperature (EGT) sensor responses. In one example, a method may include cycling an engine between a higher temperature operating mode and a lower temperature operating mode while maintaining engine torque output across the higher temperature operating mode and the lower temperature operating modes, both the higher temperature operating mode and the lower temperature operating mode providing stoichiometric exhaust gas to a downstream catalyst, and characterizing a response behavior of an EGT sensor based on output of the EGT sensor during the cycling. In this way, stepwise exhaust gas temperature changes are produced for characterizing the EGT sensor response without disrupting emissions and torque control.

摘要： Methods and systems are provided for controlling engine knock. In one example, a method may include decreasing intake valve lift at a first set of cylinders where knock is indicated and increasing intake valve lift at a second set of cylinders where knock is not indicated. A stoichiometric air-to-fuel ratio is thereby maintained.

摘要： Methods and systems are described for diagnosing degradation of a vacuum actuator in an engine system. An example method comprises indicating degradation of the vacuum actuator based on an estimate of flow of air into and out of a vacuum reservoir. The estimate is further based on flow of air generated via each of an aspirator in the intake system, an actuation of the vacuum actuator, and leakage during the actuation of the vacuum actuator.
