Abstract: This provides locations for mounting controllers and processing components that effectively employ the roof within a frame covered by a cowling so as to avoid exposure to weather and the environment. The roof is also employed to provide a sensor bar that extends across the vehicle width for a distance that does not interfere with normal vehicle function or generate potential overhangs, which can inadvertently engage objects or vehicles. The bar is sufficient in size and shape so as to allow mounting of a plurality of types of sensors on its top surface and/or recessed within front or rear edges. Such sensors can include visual light cameras for machine vison processes and/or LIDAR of various types and cooperage areas/fields of view—some of which can be recessed within a hollow region of the bar. Additional sensors can be mounted on the truck cab and/or chassis, including visual-light cameras and radars.
