  • 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.

  • Method and system for a vehicle evaporative emissions control system
    Patent number: 11333112
    Abstract: Methods and systems are provided herein for a dust box cleanout routine of an evaporative emissions control (EVAP) system of a vehicle. In one example, a method is provided for an engine of a vehicle, comprising, during travel on an unpaved road, selectively discharging a dust box housed in a vent line of an evaporative emissions control (EVAP) system by opening a discharge valve of the dust box leading to atmosphere. In this way, an accumulation of dust on the air filter and in the dust box of the EVAP system may be reduced, thereby maintaining an efficiency of the EVAP system.
