Abstract
A vehicle includes an engine; an electric machine; a transceiver, programmed to communicate with a server; and a controller, programmed to responsive to identifying a route, obtain road data associated with the route via the transceiver, wherein the road data include locations of stop signs and traffic lights, and identify a sign classification using a sign and traffic light density calculated using a total number of stop signs and traffic lights within a lookahead distance on the route, identify a road type classification using the sign classification, responsive to determining the sign and traffic light density within the lookahead distance is above a threshold indicative of a city road type classification, adjust a drivetrain of the vehicle to reduce engine operation and increasingly propel the vehicle via the electric machine.
