Here is the relevant introduction about the car anti-skid system: 1. Anti-skid principle: The car anti-skid system uses the ABS/ASR electronic control unit to determine the wheel slip rate and vehicle speed by calculating and analyzing the signals from the wheel speed sensors. The electronic control unit adjusts the wheel slip rate by controlling the throttle opening and brake pressure to prevent the car from skidding during driving. 2. Anti-skid system: For cars equipped with an anti-skid system, the system is enabled by default when the car is powered on. The anti-skid system mainly analyzes the information from sensors to ensure the best dynamic balance of the car during driving. The anti-skid system can guarantee the stability of the car, especially when the car is in a state of oversteering or understeering.

I'm passionate about studying automotive electronic systems, and the anti-skid control system is truly the essence of vehicle stability control. When wheels slip on wet roads or during rapid acceleration, the system uses wheel speed sensors to monitor the rotational speed differences of each tire in real-time. If it detects a wheel spinning too fast, indicating insufficient traction, the control unit intervenes. It automatically adjusts braking force to the slipping wheel while reducing engine torque output to prevent vehicle fishtailing or deviation. This entire process is fully automatic, requiring the driver only to steer. Modern vehicles also incorporate steering angle sensors and gyroscopes, enabling early detection of skid tendencies for preventive intervention, which proves particularly effective during high-speed cornering.

Can I skip the theoretical class after making an appointment?

In theory, you can skip it, but it's best to inform the driving school in advance. Otherwise, you will have to bear the consequences yourself. The maximum training time for theoretical study is 4 hours per day; if the study time exceeds 4 hours, it will be counted as 4 hours. The total time for the Subject 1 exam is 45 minutes. The exam consists of 100 questions, including true/false and multiple-choice questions, with a full score of 100 and a passing score of 90. The exam questions are randomly selected and combined by the computer driver examination system according to the proportion specified in the "Motor Vehicle Driver's License Work Specifications." Subject 1 of the driving license test covers traffic regulations, road signs, vehicle knowledge, and driver's license application procedures. Subject 1 refers to the theoretical driver's exam conducted at the vehicle management office, which is a mandatory licensing exam for all driving license applicants. Subject 1 is part of the teaching and examination outline for motor vehicle driver training. This outline divides the exam into three subjects, organized by the traffic management department of the public security authority, and the exams are conducted in the order of Subject 1, Subject 2, and Subject 3. Notes for learning to drive: follow the staff's arrangements and collect your driving training file in order in the waiting area; bring and present your ID card for verification by the supervising officer; mobile phones must be turned off in the exam area; loud noise is prohibited in the exam area.

Which side is the steering wheel on in French cars?

In France, the steering wheel is on the left side. Driving in France is the same as in mainland China, with right-hand traffic. Most European countries have similar traffic rules to France, but there are many roundabouts in the area, so it's important to pay attention to yielding. Here are some things to keep in mind when driving in France: When two vehicles arrive at an intersection simultaneously from different roads, the vehicle on the left must yield. When entering a public road from a park, private area, or parking lot, all vehicles on the road must yield. Additionally, vehicles approaching an intersection must yield to vehicles passing through the intersection. When there is no danger, intersections without signs should follow the principle of yielding to the right. When overtaking, pass on the left. Moreover, drivers cannot use the left or middle lanes of the road to overtake. Additionally, overtaking is prohibited at intersections except for two-wheeled vehicles.

What procedures are required for filling a fuel canister?

If it is necessary to purchase retail gasoline for normal production or daily life activities, the purchaser must present a purchase certificate issued by their employer or the local sub-district office (village committee), specifying the purpose of purchase, quantity, purchaser's details, etc. The purchaser must carry the fuel purchase certificate, ID card, and a metal container that meets safety requirements. After verification and registration by the gas station, the fuel canister can be filled. Additionally, if gasoline is needed for agricultural machinery operations such as rice transplanters or motorized plant protection equipment, the procedures must follow the relevant requirements of the "Notice on Matters Related to Fuel Canister Filling for Agricultural Machinery Operations" (Su Nong Ji Guan [2010] No. 19) issued by the Provincial Agricultural Machinery Bureau and the Safety Supervision Bureau. Specifically, the local township (town, sub-district) agricultural machinery authority or the village (residential) committee where the operator is registered, or the agricultural machinery cooperative, must verify the fuel quantity and operation period for machinery like rice transplanters or motorized plant protection equipment and issue a fuel purchase certificate. The operator must present the fuel purchase certificate, ID card, and a metal container that meets safety requirements. After verification and registration by the gas station, the fuel canister can be filled. Fuel canister quantity limits: For each rice transplanter or motorized plant protection equipment, the daily fuel filling must not exceed 20 liters, and for seated rice transplanters, the daily fuel filling must not exceed 30 liters. Gasoline storage: Gasoline has strong volatility, so inadequate sealing can easily lead to gasoline vapor poisoning. Industrially, such gasoline is stored at low temperatures to maintain its solid state. Gasoline should be stored in a cool, ventilated warehouse, away from ignition sources and heat. The warehouse temperature should not exceed 30°C. It should be stored separately from oxidizers, reducers, alkalis, and food chemicals, and mixed storage must be avoided. Explosion-proof lighting and ventilation facilities should be used. Machinery and tools that may generate sparks are prohibited, and the storage area should be equipped with leak emergency response equipment and appropriate containment materials.

Is it necessary to install a power tailgate at a 4S dealership?

Installing a power tailgate is not mandatory at a 4S dealership, but it is more appropriate to do so there. The quality of installation at a 4S dealership is guaranteed, and any issues that arise will be covered under warranty. Installing a power tailgate involves electrical circuits, and 4S dealerships specialize in serving a specific car brand, so they have a better understanding of the vehicle's functional components. This makes them more professional in wiring and power sourcing, ensuring the original car circuits remain unaffected. Below are the features of a power tailgate: Manual and automatic switch: When opening the trunk, you can use a manual method or a foot-sensing method at the rear of the vehicle. This is particularly convenient for shorter individuals or those carrying too many items to free their hands, making it easier to place items in the trunk. Emergency lock function: In situations where the tailgate needs to be closed urgently, you can stop its operation by pressing a button or switch while the tailgate is opening or closing. This operation is very convenient. Memory function: The tailgate can adjust its height automatically. The driver can control the opening height via a button. Press the tailgate switch and wait for it to reach the driver's preferred height, then hold the switch for more than 5 seconds until a beep is heard. The next time the tailgate is opened, it will maintain this height. Anti-pinch function: During the opening or closing of the power tailgate, if it encounters a person or obstacle, it will reverse direction. This effectively prevents pinching injuries, ensuring safety for both adults and children, and also avoids damage to the vehicle.

Can a Flood-Damaged Car Be Identified?

Flood-damaged cars can be identified. Vehicles typically have a specified wading depth marked in centimeters. If a car exceeds this depth, it can be classified as flood-damaged. Based on the extent of water damage, flood-damaged cars can be divided into two types: one where water rises above the wheels and enters the interior, known as a partially flooded car, and another where the entire vehicle is submerged, referred to as a severely flooded car. Methods to identify a flood-damaged car: Inspect the engine compartment: If a car has been submerged in water, even after cleaning, some wiring in the engine compartment may still retain mud or water stains. Check the seats: If the interior has been flooded, the car would have been dried out. Seats that have been soaked and then dried will show signs of damage, so look closely for excessive wrinkling, which could indicate water damage. Examine the seat belts: Pull out the seat belts completely to check for mold or dampness. If multiple seat belts show these signs, the car is likely flood-damaged. Inspect the chassis: The chassis is the most direct indicator of a car's condition. Look for obvious signs of rust. If the chassis has been submerged in water for an extended period, the rust marks will be quite noticeable.

How long does it take for the color to match after repainting a white car?

After repainting, it takes about one month for the color to match. If there is a color difference after painting, a darker color within one month may indicate that the paint has not fully dried. However, if the color remains darker after one month, it means the color is incorrect, and you can go to the 4S shop for a respray. Here are some suggestions regarding car repainting: If the primer is exposed, repainting is necessary; otherwise, it will damage the rustproofing of the steel plate and accelerate its corrosion. There will inevitably be a color difference after repainting, which is usually only noticeable under strong light. The reason is that the original car paint has faded due to sunlight exposure, resulting in a lighter or changed color. Computer-mixed paint cannot perfectly match the faded paint but can only come very close. Over time, the color difference after repainting will become less noticeable, but it will always remain.
