Radar-based vehicular exterior mirror collision avoidance system
A vehicular sensing system includes at least one radar sensor disposed at a vehicle and capturing radar data, an electronic control unit (ECU) having a data processor for processing radar data captured by the at least one radar sensor to detect an object present exterior of the vehicle. The vehicular sensing system, during a parking maneuver of the equipped vehicle, responsive to processing by the data processor of radar data captured by the at least one radar sensor, determines the detected object is within a threshold distance of a predicted path of an exterior side mirror assembly of the vehicle. The vehicular sensing system, responsive to determining the object is within the threshold distance of the predicted path of the exterior side mirror assembly of the vehicle, automatically folds the exterior side mirror assembly toward the side of the vehicle.
