Closed loop refers to the feedback interconnection between two or more systems, such that the information flows in a cycle.
Often, this interconnection is implemented by having the action of a system dependent on the deviation between the measured and desired performance.
What is the difference between open and closed loop?
– An open loop control system acts completely on the basis of input and the output has no effect on the control action. – A closed loop control system considers the current output and alters it to the desired condition. The control action in these systems is based on the output.
What does closed loop mean in automotive?
The closed loop term is used because it’s the point where the computer is basing it’s air/fuel mixture calculations on readings from all the sensors. In other words, it’s “closing the loop.” In an OBDII vehicle in closed loop, the computer is no longer running off default factory programming.
What is an example of a closed loop system?
Two very common examples of closed loop systems people use frequently are temperature control systems (house thermostat) and cruise control systems (in vehicles). Both rely on feedback and a closed-loop system to make automatic adjustments without input from a user, other than creating a set point.
