How does the computer judge when the safety officer steps on the brake?

If a dangerous situation is encountered during the test and no timely operation is made, the safety officer will naturally perform emergency braking to prevent accidents. As long as the safety officer steps on the brake to stop the vehicle, the test system will naturally evaluate it, and the test will end with a failure.
Having driven for many years, I always like to ponder how the braking system works when encountering issues. When the safety officer steps on the brake, the computer immediately captures the action through sensors, typically monitoring displacement or force changes via the pedal position or pressure sensors. Upon receiving the signal, the computer quickly analyzes it in combination with vehicle speed, road conditions, and other data—if a sudden brake is detected, it activates the ABS anti-lock system to prevent wheel lock-up or triggers the EBD brake distribution function to avoid skidding. The entire process responds in milliseconds, relying on the vehicle's ECU for continuous input processing. If a sensor malfunctions, such as dust buildup causing misjudgment, it may lead to system failure, so I regularly clean the sensor areas. Remember, any abnormalities like uneven brake feel should prompt a check of the sensors or fuses to prevent safety hazards. This is particularly crucial in daily driving, especially during rain or snow.
