Question 540Electricity & Electronics - Assistant Engineer

D) The diagram is a functional block diagram. This is the correct answer. A functional block diagram shows the overall function and interconnections of a system, without going into the detailed wiring and connections. This type of diagram is commonly used for steering control systems, as it provides a high-level overview of how the components (e.g. steering wheel, actuators, sensors) interact to provide the steering function. The other options are incorrect because: A) A one-line diagram simplifies a complex electrical system into a single line, which would not provide the level of detail shown in the illustration. B) A pictorial drawing uses images to represent the physical components, rather than functional blocks. C) A wiring diagram shows the specific electrical connections between components, rather than the overall functional relationships.
