Sense. Decide. Respond.

A controller sends a command. How does it know whether the car actually responded?

Sensors measure physical conditions. A controller interprets those signals, then commands actuators. The resulting feedback lets the controller adjust its next command.

Stability control compares driver intent, inferred from steering, with measured vehicle motion. Wheel-speed and yaw sensors provide feedback. The system can reduce drive torque and brake individual wheels.

A fault code reports an observed condition or circuit issue; it does not automatically identify a failed part. A controller depends on plausible signals, electrical supply and network communication. The learning examples simulate reasoning, not a vehicle diagnosis.

1. 1
   Sense

   Wheel-speed, steering-angle and yaw signals describe driver intent and actual motion.

2. 2
   Compare

   The controller compares the desired direction with measured movement.

3. 3
   Actuate

   Torque and individual wheel braking can be adjusted to counter instability.

4. 4
   Feedback

   New measurements let the controller assess the result and update its response.

Think it through

In a simulated stability-control loop, torque is reduced and motion is measured again. Why is that second measurement useful even though the command was already sent?

Show the reasoning

The measurement checks the physical response and informs the next command. Sending a command establishes intent; feedback is needed to assess what actually happened.
