Creating a Vehicle Rear Defogger System : Tutorial Project Definition : Basic System Description

Basic System Description

When the system is activated, it needs to time out automatically and shut its on-vehicle speed and load management. The system must provide the vehicle operator with an indicator of the current state of the system. The operator might request a change in the state of the system.

The system provides a safe temperature for defogging the rear window without overloading the electrical system nor depriving critical resources of power. Since the system performs some automatic operations, the vehicle operator needs to know if the system is on or off.

To trigger the system, the vehicle operator requests a change in state of the rear defog control system.
