  • Patent number: 11338813
    Abstract: A computer-implemented method for controlling a vehicle system of a host vehicle merging into a lane. The method includes determining an actual distance between the host vehicle and the one or more remote vehicles. The actual distance is a longitudinal distance between the host vehicle and the one or more remote vehicles. The method includes determining a safe distance for merging into the lane based on a relative position of the host vehicle to the one or more remote vehicles, a speed of the host vehicle, and a speed of the one or more remote vehicles. The safe distance is a second longitudinal distance between the host vehicle and the one or more remote vehicles. The method includes controlling the vehicle system of the host vehicle to assist a merge maneuver by the host vehicle according to the actual distance and the safe distance.

  • Patent number: 11312378
    Abstract: A computer-implemented method for controlling a host vehicle having a vehicle control system that controls motion of the host vehicle relative to a preceding vehicle that is immediately ahead of the host vehicle. The method includes determining a relative headway distance and a relative velocity between the host vehicle and the preceding vehicle, and an acceleration rate of the preceding vehicle. The method includes receiving message packets transmitted from a leading vehicle and the message packets contain parameters of the leading vehicle including an acceleration rate of the leading vehicle. Further, the method includes calculating an acceleration control rate for the host vehicle to maintain the headway reference distance between the host vehicle and the preceding vehicle, based on the relative headway distance, the relative velocity, the acceleration rate of the preceding vehicle, and the acceleration rate of the leading vehicle.

  • Patent number: 11161503
    Abstract: A vehicle control system for use with a host vehicle configured for travel along a path is described. The vehicle control system includes a processor configured to access a host location and host speed of the host vehicle. The processor is also configured to detect a follower location and follower speed of a following vehicle behind the host vehicle on the path. A tailgating distance is calculated between the host vehicle and the following vehicle. The following vehicle is identified as a tailgating vehicle when the tailgating distance is less than or equal to a first warning distance or when the follower speed is greater than the host vehicle within a second warning distance. A tailgating protocol of the host vehicle is initiated for the tailgating vehicle based on a differential speed between the host speed and the follower speed.
