Abstract: A microclimate system for a vehicle occupant includes multiple microclimate thermal effectors. Each of the microclimate thermal effectors at least partially controls a climate in at least one of multiple occupant zones. Each of the microclimate thermal effectors includes a sensor configured to determine microclimate temperature data corresponding to the zone. A controller includes an input configured to receive vehicle temperature data including cabin temperature and outside air temperature from a vehicle data bus. The controller fuses the microclimate temperature data with the vehicle temperature data and determines an estimated local equivalent temperature for each of the microclimate thermal effectors. The controller further provides a temperature command to each of the microclimate thermal effectors based upon the estimated local equivalent temperature corresponding to the microclimate thermal effector.

Abstract: A method of controlling a microclimate system includes identifying a set of multiple microclimate thermal effectors configured to provide multiple occupant zones and determining a differential temperature between a local temperature at one of the microclimate thermal effectors and a preset temperature for the microclimate thermal effectors. The differential temperature is determined for each of the microclimate thermal effectors. A fuzzy set is generated for each of the microclimate thermal effectors based upon the respective differential temperature. A respective temperature set point for each of the microclimate thermal effectors is defined based upon the fuzzy set for the corresponding microclimate thermal effectors. Each microclimate thermal effector is commanded to the corresponding respective temperature set point.

Abstract: A dual fuel system for a diesel engine includes a liquid (diesel) fuel injection system controlled by an engine electronic control unit (ECU) and a source of gaseous fuel such as natural gas. A metering valve and a mixer controls introduction of gaseous fuel from the natural gas fuel source into combustion air for the engine. An electronic governor controls the metering valve and a link controller coordinates operation of the ECU and the governor. Preferably, a regulator regulates the natural gas pressure supplied to the metering valve. A shut-off valve controls communication of natural gas between the source and the regulator. The link controller also controls the shut-off valve as a function of sensed conditions.
