Abstract: A method increases fidelity of a lane localization function aboard a motor vehicle by receiving input signals indicative of a relative position of the vehicle with respect to a roadway. The input signals include GPS and geocoded mapping data, and an electronic turn signal indicative of activation of the turn signal lever. Sensor-specific lane probability distributions are calculated via the lane localization function using the input signals. The various distributions are fused via the localization function to generate a host lane assignment. The host lane assignment corresponds to a lane of the roadway having a highest probability among a set of possible lane assignments. An autonomous steering control action is performed aboard the motor vehicle using an Advanced Driver Assistance System (ADAS) in response to the host lane assignment. A motor vehicle has a controller that performs the method, e.g., by executing instructions from computer-readable media.
