A bed cover for a vehicle that may be deployed electromechanically, either on demand or automatically, when a vehicle operator so desires, when predetermined weather conditions are detected, when the vehicle reaches a predetermined speed or experiences predetermined operating conditions, and/or when predetermined aerodynamic drag conditions are detected. The bed cover is deployable from a stowed configuration to one or more use configurations. These use configurations may include a traditional horizontal bed cover and/or an angled “cap-style” bed cover, with the angled bed cover providing enhanced aerodynamic drag reduction characteristics. A vehicle control module and camera, sensor, and/or stop trigger are used to ensure that is safe to deploy and use the bed cover, without negatively impacting an item, animal, or person present in the bed or rear cargo space of the vehicle.
