What is the principle of the ABS system?

The principle of the ABS system is: during braking, the ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that is starting to lock up, keeping the braking force constant. If the wheel continues to lock up, the normally closed output solenoid valve is opened, and the braking pressure on that wheel rapidly decreases due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking up due to excessive braking force. The functions of ABS are: 1. To maximize the effectiveness of the brakes, reducing braking time and distance; 2. To effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; 3. To allow steering during emergency braking, ensuring good steering control; 4. To avoid intense friction between the tires and the ground, reducing tire wear.

As a veteran driver with over 20 years of experience, I consider ABS systems to be absolute lifesavers! The principle is actually quite simple: when you slam on the brakes, sensors in the car constantly monitor the speed of each wheel. If any wheel is about to lock up (stop rotating), the control system immediately adjusts the braking force, alternately releasing and reapplying pressure. This prevents the wheels from completely stopping, avoiding skidding and loss of control. This technology is particularly useful in rainy or snowy conditions - when you brake hard on slippery roads, ABS kicks in to help maintain steering stability and prevent accidents. Many experienced drivers agree that combining ABS with defensive driving awareness significantly reduces rear-end collision risks. I never drive cars without ABS, especially in urban traffic jams where sudden braking is common. With the system automatically intervening, the car won't fishtail, making driving much more reassuring. Ultimately, ABS compensates for human error by making braking smarter, benefiting both novice and veteran drivers alike.

What are the annual costs of owning a car?

Annual expenses include vehicle and vessel usage tax, car insurance, fuel costs, parking fees, toll fees, maintenance costs, and expenses for traffic violations and repairs. Here is a partial introduction to these costs: 1. Vehicle and Vessel Usage Tax: This must be paid annually, and for a family car with around 2.0L displacement, the cost is approximately 500 yuan. 2. Car Insurance: Car insurance includes a compulsory traffic insurance of 950 yuan and commercial insurance. If there are no accidents or claims, the insurance premium will decrease in the future, so the insurance cost here is calculated at 5,000 yuan. 3. Fuel Costs: The average fuel consumption for a family car is about 6-8L per 100 kilometers, with an annual cost of around 7,500 yuan. 4. Parking Fees: Residential parking fees are 300 yuan/month, and company parking is estimated at 100 yuan/month, totaling about 2,500 yuan annually. 5. Toll Fees: The average toll fee is 50 yuan per trip, with an annual cost of 1,000 yuan. 6. Maintenance and Upkeep Costs: New cars require maintenance every 5,000 kilometers, and thereafter every 10,000 kilometers or every six months, with an annual maintenance cost of 4,000 yuan. 7. Traffic Violations and Repair Costs: Expenses for traffic violations and accidents can range from several thousand to tens of thousands of yuan.

Where to Make a Right Turn in a Right Turn and Straight Through Shared Lane?

When making a right turn in a right turn and straight through shared lane, you share the lane with vehicles going straight. If there are vehicles waiting ahead, you need to stop and wait for them to pass before making the right turn. The following are the rules for vehicle operation: Pay attention to lane markings: During driving, each lane has its markings. Be aware of whether the lane is a shared lane or a single lane. When passing through traffic lights, obey traffic rules, drive in order, and avoid illegal overtaking or crossing the line. Follow the yielding rules: While driving, especially when approaching a crosswalk, motor vehicles should actively yield to non-motor vehicles and pedestrians. When turning, since straight-moving vehicles at intersections usually move faster and the traffic volume is higher, while turning vehicles move slower, the principle of "turning vehicles yield to straight-moving vehicles" should be followed. This can effectively reduce road congestion and traffic accidents. If a turning vehicle fails to yield to a straight-moving vehicle and causes an accident, the turning vehicle bears full responsibility. Handling road breakdowns: If a vehicle breaks down or is involved in a traffic accident while driving in the lane, take photos as evidence, then move the vehicle to the side, turn on the hazard lights, set up a warning sign 50 meters away from the vehicle, and call the police to wait for rescue and handling.

Is an imported car considered a stock car after one year?

Stock cars refer to vehicles that remain unsold for more than three months after being manufactured and leaving the factory. Due to import channels, imported cars take 1-2 months to be transported from abroad to domestic markets, so they are considered stock cars if they exceed six months. Below is an introduction to stock cars: 1. Imported stock cars: Parallel imported cars take up to three months to arrive at the port from the time they leave the foreign factory to being imported domestically, depending on the location of the foreign factory, such as the U.S., Canada, Europe, or the Middle East. However, delays in port customs clearance can prolong this period. Therefore, imported models that have been in stock for more than six months since leaving the factory are considered stock cars. 2. Methods to identify stock cars: The engine compartment's nameplate will have the manufacturing year and month marked, and the time elapsed since then is the actual stock duration of the vehicle. Imported cars with a stock duration exceeding six months can be identified as stock cars. Additionally, if there are noticeable signs of aging on parts like wipers, engine belts, or tires, the car can also be considered a stock car. Lastly, you can check the battery by trying to power high-consumption electrical devices like high beams for about 10 minutes with the engine off. If the battery cannot sustain this, it is likely a stock car.

What to do if the BMW X5 trunk cannot be closed?

The trunk cannot be closed because the position of the trunk lock block limiter is too low, preventing it from locking. You can remove the decorative panel on the north side of the trunk to access the limiter block and then adjust the M8 screw. More information about the BMW X5 is as follows: 1. Exterior Design: Every contour of the new-generation BMW X5 exudes a powerful presence, inheriting the X family design language.
