Abstract: A NOx mass estimating unit for estimating the NOx mass output from a compression-ignition combustion engine, the engine comprising a plurality of cylinders, each cylinder comprising a combustion chamber into which fuel is injected by an associated fuel injector, said estimating unit comprising inputs for receiving data related to engine rotation and data related to in-cylinder pressure, and a processing arrangement arranged to determine a NOx mass output value in dependence on said data related to engine rotation and data related to in-cylinder pressure.

Abstract: Method and system for controlling a permanent magnet machine are provided. The method provides a sensor assembly for sensing rotor sector position relative to a plurality of angular sectors. The method allows starting the machine in a brushless direct current mode of operation using a calculated initial rotor position based on angular sector position information from the sensor assembly. Upon reaching a predefined mode-crossover criterion, the method allows switching to a sinusoidal mode of operation using rotor angle position based on extrapolating angular sector position information from the sensor assembly.

Abstract: A park interlock device for a land-based vehicle including a driver-selectable shifter for selecting a respective one of the propulsion modes of the vehicle is provided. The device includes a generally elongated, hollowed body. The device further includes an actuating rod configured to be axially disposed in said hollowed body. The actuating rod is responsive to increments in linear motion produced when the shifter is set to a new propulsion mode. A detent assembly is configured to securely engage into a respective one of a plurality of notches in correspondence with a selected propulsion mode of the vehicle. A plunger is disposed at one end of the actuating rod.

Abstract: Method, system and controller for electronically controlling a park-interlock device in a land-based vehicle are provided. The method allows for providing a driver-selectable shifter for selecting a respective one of a plurality of propulsion modes of the vehicle. One of the propulsion modes is a park mode. The method further allows for sensing at least one vehicle parameter for determining whether or not the park interlock device is to be actuated to a respective interlock state corresponding to the driver-selected mode and/or an operational mode automatically determined by a controller for stopping and starting during a Hill-hold function in an electric, hybrid electric vehicle. Memory is provided for storing nominal values for each vehicle parameter. A comparing action allows to compare the sensed vehicle parameters relative to the nominal parameter values stored in memory.

Abstract: Method and system for assembling a multisensor device that includes at least two sensors operable to provide a respective stream of pulses indicative of angular information of a rotating object are provided. The sensors are assembled so that the streams of pulses have an accurate phasing relationship relative to one another. The method allows to provide a sensor carrier. The method further allows to locate the sensor carrier to have a predefined spatial relationship relative to a target wheel. The sensor carrier includes a passageway for receiving each of the sensors. The passageway allows slidable movement to selected ones of the sensors along a phasing axis. As relative movement between the target wheel and the sensor carrier occurs, each of the sensors is energized to provide a respective stream of pulses. A determining action allows to determine the phasing relationship of each stream of pulses relative to one another.
