Governing motion and speed, this domain is what makes the automobile move. Movement is based on inputs from the driver or the driver substitute, and can be modified based on personal preferences and environmental constraints, such as road conditions.
Whether it’s part of a traditional combustion engine, an electric engine, or a hybrid of the two, the powertrain portion of this domain converts the original fuel source into power and delivers that power to the road surface. Operating conditions in the powertrain are notoriously harsh, with exposure to high temperatures and near-constant vibration.
The Vehicle Dynamics portion of this domain is where supporting subsystems, such as suspension and steering ensure stability and a smooth ride. This is also where you’ll find many of the car’s various sensor technologies, including those based on sophisticated MEMS and magnetoresistive technologies.
