PROBABILISTIC DRIVING BEHAVIOR MODELING SYSTEM FOR A VEHICLE

A hybrid probabilistic driving behavior modeling system conditioned on weather for a vehicle includes one or more controllers executing instructions to determine, by a longitudinal driving model stored by the one or more controllers, a probabilistic longitudinal velocity of the vehicle with respect to a current weather condition based on a car-following model, a semantic rule system, and a speed and visibility model. The current weather condition indicates an adverse weather condition impacting driving conditions for the vehicle. The one or more controllers determine, by a probabilistic lateral driving model by the one or more controllers, one or more lane choices for the vehicle with respect to the current weather condition based on a route plan of the vehicle and perception data indicative of an environment surrounding the vehicle and selects a final lane choice from the one or more lane choices.
