A chassis (/ˈtʃæsi/ or /ˈʃæsi/; plural: ‘chassis’ /ˈtʃæsiz/ or /ˈʃæsiz/) consists of an internal vehicle frame that supports a manufactured object in its construction and use. It is analogous to an animal’s skeleton.
The chassis sub-system refers to the internal framework that supports the powertrain and all other components, except the engine, required for driving.
Brakes, steering, and suspension are commonly known components in the chassis. Like the powertrain, sensors and actuators can be installed in the chassis domain and have stringent delay requirements.
An example of a chassis is the underpart of a motor vehicle, consisting of the frame (on which the body is mounted). If the running gear such as wheels and transmission, and sometimes even the driver’s seat, are included, then the assembly is described as a rolling chassis.
