    Abstract: A variable displacement pump for supplying fluid to a system is described. Controlling the variable displacement pump is determined based upon inputs from a fluidic pressure sensor and an accelerometer, and includes determining a desired fluidic pressure and monitoring, via the fluidic pressure sensor, an actual fluidic pressure. A pressure error term is determined based upon a difference between the actual fluidic pressure and the desired fluidic pressure. A time-integrated pressure error term is determined based upon the pressure error term, and a g-force is determined based upon an input signal from the accelerometer. The variable displacement pump is controlled in response to the time-integrated pressure error term when the g-force is greater than a threshold g-force.

    Abstract: An exhaust brake torque system for a vehicle including an engine includes a controller configured to determine a current exhaust brake torque and a maximum exhaust brake torque. A display is configured to display at least one of the current exhaust brake torque, the maximum exhaust brake torque and a percentage corresponding to the current exhaust brake torque divided by the maximum exhaust brake torque. An engine speed sensor determines an engine speed of an engine. A pressure sensor is configured to sense turbine inlet pressure. The controller is configured to calculate the current exhaust brake torque and the maximum exhaust brake torque in response to the engine speed and the turbine inlet pressure.

    Abstract: A gear assembly of a scavenge oil pump for a vehicle is provided. The assembly comprises a first pair of meshing gears comprising a first drive gear disposed about a drive shaft and a first slave gear disposed about a slave drive in parallel relationship with the drive shaft. The first drive gear and first slave gear are in rotational meshing cooperation. The assembly comprises a second pair of meshing gears comprising a second drive gear disposed about the drive shaft and a second slave gear disposed about the slave drive. The second drive gear and second slave gear are in rotational meshing cooperation. The second pair of meshing gears is disposed linearly adjacent to the first pair of meshing gears. The first pair and the second pair of meshing gears have about ⅜ of a tooth spacing relative to each other for torque transmission of scavenge oil.

    Abstract: A turbocharger includes a compressor wheel configured to pressurize an airflow for delivery to an internal combustion engine. The turbocharger also includes a turbine wheel configured to be driven by the engine's post-combustion gases and drive the compressor wheel. The turbocharger additionally includes a waste-gate assembly. The waste-gate assembly includes a first waste-gate valve and a second waste-gate valve, wherein each of the first and second waste-gate valves is configured to selectively redirect at least a portion of the post-combustion gases away from the turbine wheel into the exhaust passage. A vehicle having an internal combustion engine operatively connected to such a turbocharger and also employing a controller configured to regulate the first and second waste-gate valves is also disclosed.

    Abstract: A system includes a first scavenge oil pump that draws oil from a first draw location within a vehicle according to a first variable displacement associated with the first scavenge oil pump. The first variable displacement is based on a first modified scavenge ratio assigned to the first scavenge oil pump. An oil pump control module determines a first scavenge ratio, determines a first scavenge ratio multiplier based on at least one of vehicle acceleration and vehicle orientation, and applies the first scavenge ratio multiplier to the first scavenge ratio to generate the first modified scavenge ratio.
