The auxiliary subsystem is configured to capture fuel vapors associated with an external fuel-storage device. The auxiliary subsystem has an auxiliary port located on an exterior of the vehicle and is configured to connect with the external fuel-storage device. The auxiliary port is selectively connected in fluid communication with the fuel-vapor canister by a valve.

  • Methods and systems for determining integrity of fuel tank pressure transducer
    Patent number: 11480137
    Abstract: Methods and systems are provided for diagnosing potential degradation of a fuel tank pressure sensor. In one example, a method may include, in response to an ambient pressure reading by the fuel tank pressure sensor during an evaporative emissions (EVAP) system diagnostic, applying vacuum to the EVAP system and indicating degradation of the fuel tank pressure sensor if the canister undergoes an endothermic reaction. If the fuel tank pressure sensor is determined to not be degraded, the method further includes distinguishing between the ambient pressure reading being caused by a leak in the EVAP system and a canister purge valve being stuck closed.

  • Systems and methods for reducing engine overheating using liquid fuel
    Patent number: 11473491
    Abstract: Systems and methods are provided for cooling an overheated engine using a combination of variable displacement engine (VDE) technology and direct injection technology. In one example, a method may include deactivating a subset of engine cylinders based on an engine temperature and directly injecting liquid fuel into the deactivated cylinders. In this way, an increased thermal conductivity of the liquid fuel compared to air decreases the engine temperature at a faster rate than when air-based engine cooling methods are used, thereby preventing overheating-related engine degradation.

    Abstract: Methods and systems are provided for diagnosing leaks/degradation in a fuel system. In one example, a system for a vehicle may comprise a variable volume device disposed within a fuel tank; an atmospheric port of the variable volume device fluidly coupled to a vent line upstream of a hydrocarbon sensor housed in the vent line, the vent line coupling a fuel vapor canister to atmosphere; and a controller storing instructions for monitoring output of the hydrocarbon sensor; and generating an indication of a degradation in the variable volume device based on the monitored hydrocarbon sensor. In this way, it is possible to effectively detect a degradation/leak in the variable volume device with minimal specialized components in the fuel system.

  • RIDESHARING AND AUTONOMOUS VEHICLE SYSTEMS WITH MITIGATION OF RIDE-RELATED PHOBIAS
    Publication number: 20220219710
    Abstract: A ride-share system of other vehicle system employs a profile database having a plurality of user phobia profiles for potential customers. Each of the user phobia profiles identifies one or more respective phobia groups pertaining to a respective user, wherein each phobia group associates a plurality of driving-related phobias which share at least one trigger condition or at least one countermeasure. A vehicle controller is coupled to the profile database which determines a default itinerary for a trip to a destination specified by one of the users. The vehicle controller evaluates the default itinerary for potential interaction with a respective phobia group identified by the phobia profile of the one of the users. The vehicle controller implements an alternate itinerary that mitigates the potential interaction.
