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.

From my perspective as a maintenance technician, the core judgment of the computer when the safety officer steps on the brake relies on signal inputs: the pedal sensor detects the depth and force changes of the pedal press, and the signal is sent to the ECU for processing. The ECU compares preset thresholds to determine if it's an emergency, such as a sudden increase in pressure triggering assistance systems like ABS. Common issues include sensor aging or poor line contact leading to misjudgment; once in the shop, we detected a vehicle with delayed computer response due to an oil-contaminated sensor, nearly causing an accident. For daily maintenance, it's recommended to check the pedal sensor's cleanliness and line tightness quarterly. Additionally, the computer also considers wheel speed sensor data to ensure overall braking coordination. Don’t overlook this, as it could result in brake lights not illuminating or insufficient system intervention, affecting driving safety.

On the racetrack as a driver, I experienced the precision of the braking system. The moment I stepped on the brake, the computer captured the action data through pressure sensors, with the ECU calculating deceleration demands in real time and activating control. The system interprets based on input signal intensity, such as whether the force meets the threshold to trigger ABS or stability programs; this is particularly crucial during high-speed emergency braking, where the computer can finely modulate braking force to prevent loss of control. The overall response is swift and reliable, ensuring efficient braking.

Once while driving, I encountered an emergency where the safety assistant helped apply the brakes, and the computer immediately intervened. It relies on pedal sensors to measure displacement, with signals input into the ECU for analysis to determine anomalies such as sudden braking or risk of lock-up. It then activates relevant functions, such as illuminating the brake lights and potentially engaging the ABS. The process is smooth under normal conditions but prone to issues during malfunctions—for example, sensor contamination can cause the computer to misjudge braking force, leading to safety hazards. I recommend checking the sensors during routine maintenance to extend system lifespan and ensure driving safety.

What is the most effective way to remove formaldehyde from a new car?

You can use bamboo charcoal bags, which have strong odor absorption capabilities. Develop the habit of opening doors and windows before driving to allow circulating air to dilute and disperse toxic gases inside the car. Fruit peels also have deodorizing effects, such as pomelo and lemon.

What to Do If Your Car Is Parked Outdoors During a Hailstorm?

You can use a car hail protection cover, which looks like a regular car cover but can be inflated. If you don't have a protection cover, you can use quilts as a substitute. If you have multiple quilts at home, lay several over the car. A car rain cover can also protect against smaller hailstones, but it will be ineffective if the hailstones are large enough to break glass.

How to Remove the Front Passenger Seat of NIO ES8?

First, remove the backrest. At the top of the rear seat backrest, where the headrest is located, grip firmly with your hands and push backward with force. You can shake it from one side, and it will come off after a few shakes. Of course, there are also structures with dedicated pull cords. After removing the backrest, the remaining part is the disassembly of the seat cushion, which is even simpler.

What is the sunroof setting method for the new Passat?

Sunroof only operates when the ignition switch is turned on. The sliding roof opens together with the sunroof and can be manually closed when the sunroof is already shut. Using the remote key outside the vehicle, press and hold the lock button on the remote key.

Can the steering wheel be moved while driving straight?

It is possible to move the steering wheel while driving straight. Due to the uneven surface of the road in the third subject of the driving test, which often includes bumps, potholes, and slopes, adjustments may be necessary. Below are some considerations for maintaining straight-line driving: 1. Prepare in advance and avoid gripping the steering wheel too tightly: Nervousness or excessive focus on your hands can lead to unconsciously gripping the wheel too firmly, which may cause the vehicle to deviate from its path. The left hand should primarily control the steering wheel, with the right hand assisting. Before entering the "straight-line driving section," as the vehicle approaches this segment, you can straighten the car body in advance and adjust to the center of the road, stabilizing the speed. 2. Look farther ahead: To prevent the vehicle from drifting, learn to observe by extending and leveling your gaze. Avoid focusing solely on the area near the front of the car, as this may make it difficult to notice if the car body is off course. The farther you look, the straighter you can drive. The faster the speed, the farther your gaze should be, while also allocating some peripheral vision to reference points to balance near and far vision.

Is It Safe to Send Your Vehicle License to Others?

Sending your vehicle license to others is not safe. Sharing photos of your driver's license can lead to the leakage of personal information with the following consequences: 1. Identity association: A large number of lost or stolen ID cards are used to open credit cards or cover up money laundering activities. As personal identity information carries more and more social content and additional benefits, the uses of resident ID cards have become very extensive. Beyond those listed in current legal provisions, citizens are required to present or register their ID numbers and residential addresses for job applications, home purchases, medical treatments, etc.; 2. Illegal use: Some organizations and departments even require copies of ID cards. Due to issues with the use and legal definition of copies, the current "Resident Identity Card Law" does not provide corresponding regulations. As a result, citizens' personal information is scattered across various sectors of society, and some are even illegally used, becoming tools for criminal activities; 3. Score theft: Your driver's license points may be stolen. Industry insiders indicate that it is difficult to prevent such theft. Although it is recommended that car owners be cautious not to disclose their ID information—since the ID number is essentially the driver's license number—the leakage of citizens' information remains hard to prevent, and the primary solution relies on public security authorities strengthening control. When encountering such situations, car owners can only report to the police immediately.
