    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.
