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.

Claim (Index 11):
A system for pedestrian warning in a vehicle, the system comprising:\n a traffic controller external to the vehicle; and a vehicle controller receiving pedestrian information from the traffic controller external to the vehicle, the vehicle controller configured to generate a pedestrian detection warning based on evaluating the pedestrian information, the generation of the pedestrian detection warning comprising:\n constructing a pedestrian zone based on pedestrian information that is received from the traffic controller external to the vehicle; \n computing a vehicle trajectory that predicts a path for the vehicle; \n determining a minimal distance between the pedestrian zone and the vehicle trajectory; \n predicting a time to collision by computing a time for the vehicle to reach a location corresponding to the minimal distance along the vehicle trajectory; and \n in response to the time to collision being below a threshold, generating a warning for an operator of the vehicle, wherein the vehicle controller is further configured to compute a time-decay risk as: Risk = Ref_Safe \ue89e _Distance Minimal_Distance \u00b7 CV , where Ref_Safe_Distance is a predetermined parameter and CV is a time decayed confidence-value indicative of a pedestrian being present in the pedestrian zone, and wherein the vehicle controller predicts the time to collision in response to the time-decay risk being greater than a risk threshold.
