Abstract: A system for determining an optimal behavior for a vehicle includes at least one vehicle sensor and a controller in electrical communication with the at least one vehicle sensor. The controller is programmed to determine an ingress stop bar location and an egress stop bar location of a traffic-signal-controlled intersection in a path of the vehicle using the at least one vehicle sensor. The controller is further programmed to determine a current signal phase of the traffic signal using the at least one vehicle sensor. The controller is further programmed to determine a location of a first remote vehicle using the at least one vehicle sensor. The controller is further programmed to determine the optimal behavior for the vehicle based at least in part on the ingress stop bar location, the egress stop bar location, the current signal phase, and the location of the first remote vehicle.

Abstract: A full speed range adaptive cruise control system for a vehicle that stops at an intersection includes one or more controllers that execute instructions to receive localization data and situational data related to the vehicle. The one or more controllers determine, based on localization data and situational data, that the vehicle is approaching an intersection and will come to a stop at the intersection, where the vehicle is part of a queue including one or more surrounding vehicles. In response to determining the vehicle has come to a stop, the controller determines a position of the vehicle within the queue and an overall length of the queue. The controller calculates an adaptive launch time based on at least the position of the vehicle within the queue, the overall length of the queue, the situational data, and a timing delay associated with the queue.

Abstract: A method and system of map data reconciliation in connected vehicles. The method includes processing information to detect a same object; determining an identification of the same object; determining a confidence level of the identification of the same object; determining a probability mass function (PMF) of the identification of the same object using Dempster-Shafer Theory; determining a most probably identification of the same object based on the PMF; and communicating the most probably identification of the same object to a vehicle to implement a vehicle function. The system includes a conflict resolution module configured to receive confidence levels from multiple vehicles detecting the same object and to determine a reconciled identification of the same object using an algorithm based on Dempster-Shafer Theory, and a weight calculation module configured to apply a weight function based on a scene context weight function and on a historical score of the vehicles.

Abstract: A one pedal driving system for an electric vehicle including one or more electric motors includes a controller in wireless communication with one or more external vehicle networks. The controller executes instructions to receive, from the one or more external vehicle networks, an active zone notification that indicates the electric vehicle is traveling into a one pedal driving zone. The one pedal driving zone represents a section of roadway where the electric vehicle decelerates from an initial speed. The controller executes instructions to receive a pedal notification that a driver foot is removed from an accelerator pedal of the electric vehicle. In response to receiving the active zone notification and the pedal notification, the controller instructs the electric vehicle to decelerate from the initial speed by a regenerative braking torque that is created by the one or more electric motors to counteract a forward momentum of the electric vehicle.

Abstract: A method of correcting a GPS vehicle trajectory of a vehicle on a roadway for a high-definition map is provided. The method comprises receiving first bitmap data from a first sensor of a first vehicle to create a plurality of first multi-layer bitmaps for the first vehicle using the first bitmap data and receiving second bitmap data from a plurality of second sensors of a plurality of second vehicles to create a plurality of second multi-layer bitmaps. The method further comprises creating first probability density bitmaps and an overall probability density bitmap with a probability density estimation, and matching an image template from each of the first probability density bitmaps with the overall probability density bitmap to define match results. The method further comprises combining the match results to define combined utility values and determining the maximal utility value with the combined utility values.

Abstract: A method includes obtaining information about a lead vehicle. The lead vehicle is traveling directly ahead of the host vehicle and the information includes velocity of the lead vehicle and a gap g between the host vehicle and the lead vehicle. Based on detecting a change in the velocity of the lead vehicle in the information, a corresponding desired acceleration is computed for the host vehicle using perceived acceleration of the lead vehicle to maintain the gap g within a specified range of gap values. The perceived acceleration of the lead vehicle is based on the change in the velocity indicated by the information. Based on a check of parameters involved in the computing the corresponding desired acceleration, a modified desired acceleration is computed for the host vehicle using a lag for the lead vehicle that results in an intended acceleration of the lead vehicle differing from the perceived acceleration.

The method includes receiving, by a processor, intersection data transmitted by an infrastructure associated with the intersection, the intersection data including at least a position of a plurality of lanes associated with the intersection. The method includes receiving, by the processor, a position of the vehicle, and determining, by the processor, a current lane of travel of the vehicle and a future lane of travel of the vehicle based on the intersection data and the position of the vehicle. The method includes determining, by the processor, a virtual lane through the intersection, the virtual lane providing a path of travel for the vehicle from the current lane of travel to the future lane of travel. The method includes controlling, by the processor, the vehicle based on the virtual lane.

Abstract: Technical solutions are described for generating a pedestrian detection warning in a vehicle. An example method includes constructing, by a vehicle controller, a pedestrian zone based on pedestrian information that is received from a traffic controller. The method further includes computing, by the vehicle controller, a vehicle trajectory that predicts a path for the vehicle. The method further includes determining, by the vehicle controller, a minimal distance between the pedestrian zone and the vehicle trajectory. The method further includes predicting, by the vehicle controller, a time to collision by computing a time for the vehicle to reach a location corresponding to the minimal distance along the vehicle trajectory. The method further includes in response to the time to collision being below a threshold, generating, by the vehicle controller, a warning for an operator of the vehicle.
