Automotive Sensors and Actuators

This handbook provides a detailed study of the sensors and actuators at the heart of modern vehicle electronics. It begins with basic electrical and electronic concepts, introducing the principles and terminology essential for understanding automotive systems.

The book explores sensors and actuators on a system-by-system basis, including:

• Fundamentals of electrical engineering, electromagnetic phenomena, and motor principles
• Passive and active electronic components, integrated circuits, protection devices, and automotive-grade electronics
• Sensor characteristics, signal conditioning, ADCs, PWM and frequency outputs, and interface adaptation
• Automotive communication links and protocols, including LIN and SENT
• Engine sensors: air mass, pressure, temperature, speed, position, exhaust and emissions-related sensors
• Transmission sensors for manual and automatic systems
• Steering and suspension sensors for conventional and active systems
• Vehicle body and electrical system sensors for comfort, climate, access, and monitoring functions
• Engine actuators such as throttle bodies, injectors, turbo actuators, EGR systems, ignition components, and pumps
• Transmission, brake, steering, suspension, and body actuators
• Identification and coding of electronic components and packages commonly used in automotive applications

The structure and operating principles of each component are explained, with relevant electronic circuitry illustrated. Its system-oriented organization and practical focus make it a valuable reference for understanding, testing, and troubleshooting automotive electronic systems.
