Abstract: A method and system for operating a vehicle that includes a plurality of engine starting devices and an internal combustion engine is described. In one example, the method determines whether or not to inhibit automatic engine stopping so that a lifespan of an engine starting device may be extended. In one example, the inhibiting is based on a ratio of an actual total number of engine starts generated via the engine starting device to an actual total distance traveled by the vehicle since the engine starting device was installed.

Abstract: A method for operating a vehicle that includes a DC/DC converter is described. In one example, the method includes adjusting an output voltage of the DC/DC converter after the DC/DC converter is used to crank an engine. The output voltage of the DC/DC converter may be adjusted responsive to a state of charge of an ultra-capacitor.

Abstract: Methods and systems are provided for improving vehicle speed measurements. A vehicle may detect the impact of a roadway irregularity to its front wheels and its rear wheels, and may calculate an instantaneous vehicle speed on the basis of its wheelbase and an elapsed time between the two impacts. This instantaneous vehicle speed may then be used to calculate one or more correction factors which may be used to correct a conventionally-acquired vehicle speed measurement, an operational parameter of the vehicle underlying such measurements (such as a wheel size or a final drive ratio), or both.

Abstract: Methods and systems are provided for diagnostics of a gasoline particulate filter in an exhaust system. In one example, a method may include indicating degradation of a hose coupled across a particulate filter responsive to a difference between a first differential pressure and a second differential pressure being greater than a threshold, the first differential pressure measured by a differential pressure sensor positioned in the hose responsive to a downstream exhaust tuning valve being fully open, the second differential pressure measured by the differential pressure sensor responsive to the exhaust tuning valve being fully closed.

Abstract: 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.

Abstract: Systems and methods for operating an engine and a torque converter are presented. In one example, slip of a torque converter is adjusted via at least partially closing or opening a torque converter clutch in response to vehicle vibration. The vehicle vibration may be based on road surface conditions and an actual total number of operating cylinders of the engine.

Abstract: Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Sensor output is compensated with a term based on vehicle motion parameters to compensate for fluid level distortion due to motion-induced slosh.

Abstract: Methods and systems for diagnosing operation of a compression ratio adjusting mechanism are described. In one example, an output of a pressure sensor is sampled and an assessment of the engine's present compression ratio is made after adjusting sampling of the output. Engine operation may be adjusted responsive to whether or not degradation of the compression ratio adjusting mechanism is indicated.

Abstract: Methods and systems are provided for diagnostics of a gasoline particulate filter in an exhaust system. In one example, a method may include during conditions where a differential pressure sensor is exposed to changing exhaust pressure, indicating degradation of a hose coupled across a particulate filter in an exhaust system responsive to a change in differential pressure measured by the differential pressure sensor being different than an expected change, the differential pressure sensor positioned in the hose and the particulate filter positioned upstream of an exhaust tuning valve.

Abstract: Systems and methods for operating an engine with deactivating and non-deactivating valves are presented. In one example, fuel supplied to cylinders being reactivated is supplied by direct fuel injectors even though the engine is operating in a region (e.g., speed and torque) where under conditions where cylinders are not being reactivated the engine injects fuel solely via port fuel injectors.
