  • Patent number: 9919582
    Abstract: A computing device determines that a first time for a first sound generated by a vehicle to reach a first sound maximum amplitude and a second time for a second sound generated by the vehicle to reach a second sound maximum amplitude are within a range. An object that reflects the second sound is identified based on an interval between receipt of the first and second sounds. A speed of sound is determined based at least in part on the time interval and a distance to the object. A humidity is determined based at least in part on the speed of sound. A vehicle subsystem is adjusted based on the humidity.

  • Publication number: 20180058769
    Abstract: Methods and system for operating a thermal storage device of a vehicle system are provided. In one example, a method comprises determining a state of charge of the thermal battery based on an accurate estimation of a melting temperature of one or more phase change materials (PCMs) at a specific aggregate pressure inside the thermal storage device. Variation in melting temperature of the PCM may be minimized by reducing pressure variation inside the thermal storage device by regulating a position of one or more pressure relief valves of the thermal storage device.

  • Patent number: 9827827
    Abstract: Methods and systems are described for preventing condensation on a windshield and other windows of a parked vehicle. One method includes following the vehicle shut down, and when a temperature of a windshield is lower than ambient dew point, transferring heat from a powertrain of the vehicle to the windshield via a coolant if a powertrain temperature is higher than the windshield temperature, and transferring heat from ambient air to the windshield via the coolant if the powertrain temperature is lower than the windshield temperature, and ambient temperature is higher than the windshield temperature.

  • Patent number: 9777646
    Abstract: A method for operating an engine, comprising port injecting a first quantity of a first gaseous fuel in a cylinder cycle and direct injecting a second quantity of a secondary injectant in the cylinder cycle as a function of a desired air-to-fuel ratio (AFR), the desired AFR based on a temperature of an engine cylinder valve. The desired AFR may be outside the AFR range available during natural gas combustion alone and thus allows for cooler engine operation.

  • Publication number: 20170210196
    Abstract: Methods and system for operating a thermal storage device of a vehicle system are provided. In one example, a method comprises estimating a temperature of a thermal battery after the battery and coolant included therein have reached thermal equilibrium, and determining a state of charge of the battery based on the estimated temperature and one or more chemical properties of two phase change materials included within the battery. Specifically, the thermal battery may include two phase change materials with different melting points for providing thermal energy to warm coolant in a vehicle coolant system.

  • Patent number: 9696100
    Abstract: Methods and systems are described for heating a powertrain prior to an engine start. One method includes heating a coolant by circulating the coolant through a radiator and operating an electric radiator fan, and flowing the coolant across the powertrain.

  • Patent number: 9644506
    Abstract: Methods and systems are described for an oil delivery system of an engine. In one method, oil is pumped via a lower pressure oil pump to piston cooling jets while oil is separately pumped via a higher pressure oil pump to a cylinder head, bearings, a turbocharger, or a variable valve operation system. Herein, the higher and lower pressure oil pumps each draw oil from a common, shared sump, and return oil back to the common, shared sump.

  • Patent number: 9631629
    Abstract: A method for controlling air flow through a compressor recirculation passage, comprising: during a first condition: reducing air flow through the compressor recirculation passage based on a margin, the margin based on a rate of air flow at a compressor inlet, a rate of air flow through the compressor recirculation passage, and a rate of EGR flow. In this way, the CRV recirculation flow may be controlled to be less than the amount that could potentially backflow into an air filter disposed in the air intake passage, thus preventing EGR contained in the CRV recirculation flow from fouling the air filter with soot, oil and water.
