  • Publication number: 20220238023
    Abstract: Systems and methods for customizable autonomous vehicle service for large scale events. A centralized ride management system allows event hosts to integrate with a rideshare vehicle fleet for booking, customizing, tracking, and managing guest rides. The centralized ride management system collects basic event information from the host, such as event location, event start time, number of event guests, and guest pick-up locations. Using this information, the centralized ride management system schedules various guest pick-up times and determines routes to the event location that optimize traffic conditions and reduce congestion at the drop-off location.

  • Patent number: 11396306
    Abstract: Presented are driver alert systems with control logic for powertrain energy tracking and reporting, methods for making/using such systems, and electric-drive vehicles with alert systems for providing driver cues to indicate real-time potential energy buildup in the powertrain. A method of operating a driver alert system for an electric-drive vehicle includes a vehicle controller receiving a selection of a powertrain operating mode. Responsive to the received selection, the vehicle controller determines a buildup of output torque generated via an electric traction motor for an impending vehicle maneuver associated with the selected powertrain operating mode. The controller accesses a memory-stored, torque-based lookup table to retrieve an output level calibrated to an in-vehicle sensory output device and corresponding to an output torque value for the determined torque buildup.

  • Patent number: 11396335
    Abstract: Presented are flutter countermeasure devices and control logic for active aerodynamic systems, methods for making/using such active aero systems, and vehicles equipped with spoiler flutter countermeasure devices for increasing downforce and decreasing drag. A method of operating an active aerodynamic system of a motor vehicle includes detecting, via a system controller based on sensor data received from one or more sensing devices, a flutter excitation experienced by a spoiler of the active aero system during operation of the motor vehicle. The controller determines a harmonic oscillation amplitude of the flutter excitation experienced by the spoiler, and then determines if this harmonic oscillation amplitude exceeds a vehicle-calibrated threshold amplitude. If so, the system controller determines a damping force sufficient to mitigate or eliminate the harmonic oscillation amplitude.
