The SAE plans to extend AS6969™ with a quantity domain for vehicle kinematics. This quantity domain will define vehicle measurands and measurements for quantities of space and time. For this domain, the term ‘vehicle’ is defined as:
A vehicle is an artificial (i.e. man-made) body that can change its position through changes in its kinematic state. The term applies to both manned (inhabited) vehicles and unmanned (uninhabited) vehicles. Various kinds of vehicle are defined according to the medium through which they move and the means of propulsion.
An air vehicle is any vehicle whose medium of movement is air. The term includes, but is not limited to, airplanes, airships, helicopters, gliders, and guided missiles. A ground vehicle is any vehicle whose medium of movement is the ground surface or through the ground. The term includes, but is not limited to, wheeled vehicles, tracked vehicles, and boring vehicles. An aquatic vehicle is any vehicle whose medium of movement is the water surface or through the water body. The term includes, but is not limited to, boats and ships, submersibles, torpedoes, and self-propelled mines.
