What Are Sensors and Actuators in Modern Vehicles
Automotive computers are electronic control units that manage various vehicle systems, such as the engine, transmission, brakes, and climate control. They receive input from sensors and use algorithms to make real-time adjustments to optimize performance, efficiency, and safety. These computers play a crucial role in modern vehicles by monitoring and controlling essential functions to ensure a smooth driving experience. This article will detail the many sensors and actuators the PCM uses to make its logical decisions.
How the PCM Uses Sensor Inputs to Make Decisions
The Powertrain Control Module (PCM) receives input signals from multiple sensors throughout the vehicle. These signals are compared to programmed values and operating conditions to determine appropriate output commands. Based on this data, the PCM adjusts fuel delivery, ignition timing, and emissions-related functions in real time.
Common Sensors Used in Emissions and Engine Control
Modern vehicles rely on a variety of sensors to monitor engine and emissions performance. These sensors provide critical data that allows the PCM to calculate air-fuel ratios, detect operating conditions, and control emissions output.
