  • Starters: Modern vehicles often have computer-controlled starters that manage the ignition and cranking of the engine. These starters can be more precise and efficient than traditional ones.
  • Alternators: Alternators are responsible for generating electrical power in a vehicle. Computer control can help optimize charging rates and adapt to different driving conditions, which can enhance fuel efficiency.
  • Air Conditioning Systems: Many contemporary vehicles feature computer-controlled climate control systems. These systems allow for precise temperature regulation, air distribution, and energy management.
  • Engine Management: The engine itself is heavily controlled by computer systems. Engine control units (ECUs) monitor and adjust various parameters, such as fuel injection, ignition timing, and emissions, for optimal performance and efficiency.
  • Transmission Control: Automatic transmissions are typically controlled by computers, which can manage gear shifting, torque distribution, and adapt to driving conditions for smoother operation.
  • Safety Systems: Advanced safety systems, such as anti-lock brakes (ABS), traction control, and stability control, rely on computer control to improve vehicle stability and safety.
  • Entertainment and Infotainment: Many vehicles have sophisticated infotainment systems that include touch screens, navigation, and connectivity features. These systems are controlled by onboard computers.
  • Advanced Driver Assistance Systems (ADAS): ADAS features like adaptive cruise control, lane-keeping assist, and collision avoidance systems rely on sensors and computer algorithms to enhance driver safety.
