  • Publication number: 20170179865
    Abstract: A method for operating an electromagnetic actuator includes an actuation event utilizing a current waveform for the actuator characterized by an initial peak pull-in current in a first direction of current flow when the actuator is commanded to an actuated position; and a reversed peak current in a second opposite direction of current flow applied after the actuator is commanded to a rest position. The reversed peak current has a magnitude that is greater than the magnitude of the initial peak pull-in current.

  • Publication number: 20170178846
    Abstract: An actuation apparatus includes a module movably tethered to a base member. Each of the module and base member include a plurality of magnetic elements aligned in a plurality of paired magnet sets such that in a non-actuated condition a repulsive magnetic force generated by each paired magnet set causes separation of the module and base member. Application of an actuation force to an actuation surface of the module, in opposition to the magnetic repulsive force, causes movement of the module toward the base member such that contact is made between terminals defined by the magnetic elements of at least one of the paired magnet sets, to generate an output signal. In an illustrative example, the base member is a steering wheel armature of a vehicle and the module is a wheel hub assembly including an air bag and a hub cover defining the actuation surface.

A value of an exhaust gas temperature is measured upstream of the lean nitrogen-oxide trap. An electric heated catalyst enabling condition may be fulfilled if the storage efficiency of the lean nitrogen-oxide trap is smaller than a threshold value thereof and the value of the exhaust gas temperature upstream of the lean nitrogen-oxide trap is greater than a lower threshold value and less than an upper threshold value. The electric heated catalyst is activated if the enabling condition is fulfilled. An inhibition enabling condition may be fulfilled if the value of storage efficiency is less than a second threshold value and the electric heated catalyst is deactivated and a denitrification of the lean nitrogen-oxides trap is started.

  • Publication number: 20170167416
    Abstract: A method and system for operating an internal combustion engine equipped with a turbocharger and an exhaust gas recirculation pipe fluidly connecting an exhaust gas line to an air intake duct upstream of a compressor of the turbocharger is disclosed. A value of a parameter indicative of a temperature of an exhaust gas is determined, and an internal recirculation strategy of the exhaust gas is actuated if the determined value is lower than a predetermined threshold value thereof. The internal recirculation strategy includes interrupting a flowing of exhaust gas through the exhaust gas recirculation pipe, and opening an exhaust valve during an intake stroke of a piston of the internal combustion engine.

  • Publication number: 20170166242
    Abstract: A method of tuning a calibration table for an electric power steering system includes connecting the electric power steering system to an actuator machine, and communicating a control input from a vehicle simulator to the actuator machine. Input forces and steering angles are applied to the electric power steering system with the actuator machine, based on the control input. The electric power steering system is controlled with a steering controller, to apply a steering setting, i.e., and assistive torque. The steering controller uses the calibration table to define the steering setting, based on the applied input forces and steering angles. A steering torque in the electric power steering system generated in response to the applied steering setting is sensed, and communicated to the vehicle controller, thereby establishing a closed loop, feedback system. The calibration table may then be re-defined based on the sensed steering response for the applied input forces.

  • Patent number: 9677495
    Abstract: A fuel control system includes a target rail pressure module. The target rail pressure module determines a target fuel rail pressure of a fuel rail of a direct injection engine. An offset module determines an offset value based on an engine speed of the direct injection engine and at least one of an engine load and an air per cylinder. A modifier module determines a modifier value based on a temperature of the direct injection engine. A rail pressure control module adjusts a current fuel rail pressure of the fuel rail based on the target fuel rail pressure, the offset value and the modifier value.

  • Patent number: 9677145
    Abstract: A press-hardened steel component and a method of producing the same. In one form, a workpiece that will be formed into the component includes a coating that is pre-diffused with metal from the workpiece substrate. Examples of such protective coatings may include aluminum-based coatings, as well as from aluminum and silicon combinations. The pre-diffusion of the workpiece permits it to be subjected to the high heating rate of a subsequent press hardening operation without causing localized melting or vaporization of the protective coating.

  • Patent number: 9677451
    Abstract: An electronic control module for operating an internal combustion engine is disclosed. The electronic control module is configured to monitor a first air-fuel equivalence ratio of engine exhaust gases upstream of a NOx trap, and to activate a diagnostic routine for the NOx trap when the first air-fuel equivalence ratio is smaller than one. The diagnostic routine enables the electronic control module to monitor a second air-fuel equivalence ratio of engine exhaust gases downstream of the NOx trap, to use the first and second air-fuel equivalence ratios to calculate an index that is representative of the conversion efficiency of the NOx trap, and to identify a failure of the NOx trap when the efficiency index is lower than a predetermined threshold value.
