Abstract: A system and method for controlling the regeneration of an exhaust gas particulate filter. When regeneration is initiated, an outlet temperature of an exhaust gas oxidation catalyst and an outlet temperature of the exhaust gas particulate filter are detected. As part of a closed loop non-linear temperature targeting regime, the maximum of the outlet temperature of the exhaust gas oxidation catalyst and the outlet temperature of the exhaust gas particulate filter is set as a reference temperature. A regeneration temperature target is initialized and indexed based on a profile time and the reference temperature. As part of a closed loop fuel control regime at least one hydrocarbon dosing value is determined based on an exhaust mass flow, the reference temperature, and the regeneration temperature target.

Abstract: A damper system for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.

Abstract: An exhaust treatment system may include a burner, a flame sensor assembly and a control module. The flame sensor assembly may be at least partially disposed within the burner and may include an insulator and an electric heating element in heat transfer relation with the insulator. The control module may be in communication with the flame sensor assembly. The control module may determine whether a flame is present in a combustion chamber based on feedback from the flame sensor assembly. The control module may detect contamination on the insulator based on feedback from the flame sensor assembly. The control module may operate the heating element in a first mode in response to detection of a contamination in which the control module causes electrical power to be applied to the heating element to raise a temperature of the heating element to burn contamination off of the insulator.

Abstract: A hydraulic actuator includes a shock absorber and a control system that is separate from the shock absorber and which generates damping loads for the hydraulic actuator. The control system generates the damping load by using a pair of variable valves, a pair of check valves, an accumulator, a pump/motor and a flow controller. The forces are generated in all four quadrants of compression/rebound and active/passive. A device which recuperates the energy generated by the hydraulic actuator can be incorporated into the hydraulic actuator to generate energy in the form of electrical energy.
