Abstract: Systems and method are provided for carwash detection and entry assistance of a vehicle. A system includes a controller that operates to identify the presence of the vehicle at a wash facility, and to determine whether an operator of the vehicle has accepted entry assistance. When the operator has accepted entry assistance, the controller prepares the vehicle for entering the wash facility, determines a path into the wash facility, and assists the operator in entering the vehicle into the wash facility via the path.
