Study Notes

Characteristics of a System

Systems contain interacting elements, forming a natural structure.
Distinction between two types of systems:
- System of Interest: Under development.
- Enabling System: Interacts with or has interest in the System of Interest.
System Elements can be hierarchically structured, allowing for multiple levels of breakdown.
Interaction between System Elements is crucial for understanding and applying Systems Engineering.

System Elements in Cars

Four primary System Elements in a car:
- Body: Comprises wings, doors, mirrors.
- Chassis: Includes brakes, wheels, suspension.
- Interior: Contains seats, dashboard, controls.
- Drive Train: Comprises the motor and gearing.
Older cars are primarily mechanical, with limited electrical components (lights, indicators, fan, and wipers).
Mechanical interfaces dominate, resulting in simpler integration processes.

Evolution to Modern Cars

Modern cars incorporate electronic and software-based System Elements, vastly differing from older mechanical systems.
Types of Electronic System Elements:
- Controllers: Manage various functions like lighting and indicators.
- Sensors: Monitor parameters such as temperature and pressure.
- Actuators: Facilitate movement via levers and small motors.
- Display Elements: Dashboard lights and alerts.
Software in modern cars is distributed across multiple nodes, requiring complex communication systems (e.g., Controller Area Networks).

Complexity of Modern Systems

Interfaces in modern cars have become more intricate, involving data transfer and communication protocols.
Integration now requires understanding subtle changes in voltage and current, along with complex wiring setups.
Overall complexity has increased, not just in quantity of System Elements but also in their operational nature.

Persistence of Basic Need

The fundamental need for transportation remains unchanged: moving people from point A to B.
Retrospective shift in automotive design focus has evolved from speed alone to encompass other critical factors.
