This Decision logic determines the appropriate operation of a vehicle's headlights by evaluating the current status of the lights against various environmental conditions. The goal is to automate safety actions, ensuring lights are active during hazardous or low-light situations and conserved when conditions are clear.

Solution components:

The solution consists of a single Decision Table named "Automatic Car Headlights". This table processes four specific input variables to determine a single output action.

• Inputs:

  • headlightStatus: Indicates if the lights are currently "On" or "Off".

  • nightTime: A boolean indicator (Yes/No) regarding the time of day.

  • poorVisibility: A boolean indicator (Yes/No) regarding weather or clarity.

  • tunnel: A boolean indicator (Yes/No) regarding whether the vehicle is inside a tunnel.

• Output:

  • action: Defines the Next Action, such as "Turn headlights ON," "Turn headlights OFF," or "Do nothing".

Rule Logic: 

The Decision Table evaluates the inputs through the following logic rows:

• Activation Logic (Turning ON):

  • If the headlights are Off and poorVisibility is "Yes," the action is "Turn headlights ON".

  • If the headlights are Off and nightTime is "Yes," the action is "Turn headlights ON".

  • If the headlights are Off and tunnel is "Yes," the action is "Turn headlights ON".

• Deactivation Logic (Turning OFF):

  • If the headlights are On, and it is not nghtTime, notpoorVisibility, and not a tunnel, the action is "Turn headlights OFF".

• Do Nothing:

  • If the headlights are Off, and all environmental indicators (nightTime, poorVisibility, tunnel) are "No," the action is "Do nothing".

  • If the headlights are On, and any of the environmental conditions persist (captured by the ELSE logic in the final row), the action is "Do nothing".

Use this logic block as a standalone safety feature for vehicle control systems or integrate it into larger driver-assistance modules.
