  • Publication number: 20210280054
    Abstract: Disclosed herein is a virtual pedestrian traffic light (VPTL) system and method that provides an infrastructure-free way to provide the right-of-way to pedestrians at intersections. The invention is most effective when integrated with existing virtual traffic light (VTL) systems to provide complete infrastructure-free control of traffic at intersections.

  • Patent number: 10284387
    Abstract: Technical solutions are described for facilitating intra-vehicle wireless communication among a plurality of electronic control units. An example method includes determining, by a first electronic control unit in a vehicle, a wait-time for a message, which is to be transmitted to a second electronic control unit in the vehicle via a wireless channel. The first electronic control unit executes a first availability-check, by determining availability of the wireless channel. In response to the first availability-check indicating that the wireless communication channel is available, the method includes delaying transmission of the message by the wait-time. The method also includes executing, by the first electronic control unit, after passage of the wait-time, a second availability-check. In response to the second availability-check indicating that the wireless communication channel is still available, the method includes transmitting the message for receipt by the second electronic control unit.

  • Patent number: 10178176
    Abstract: Methods and systems for communicating data between a network and devices of a vehicle are provided. A method includes: determining, by a processor, a value associated with a round trip time based on vehicle information; adjusting, by the processor, a size of a window used in communication with the network based on the value; and communicating data at least one of to and from the network based on the size of the window.

  • Patent number: 9761136
    Abstract: Methods and software for managing vehicle priority proximate to a potential travel-priority conflict zone, such as a roadway intersection, where travel conflicts, such as crossing traffic, can arise. Coordination involves forming an ad-hoc network in a region containing the conflict zone using, for example, vehicle-to-vehicle communications and developing a dynamic traffic control plan based on information about vehicles approaching the conflict zone. Instructions based on the dynamic traffic control plan are communicated to devices aboard vehicles in the ad-hoc network, which display one or more virtual traffic signals to the operators of the vehicles and/or control the vehicles (for example, in autonomous vehicles) in accordance with the dynamic traffic control plan, which may account for a priority level associated with one or more of the vehicles.
