Normally, vehicles will automatically straighten the steering wheel after releasing the hand, which is a basic function of cars. Steering wheel returning to center during turns: When a car is turning, the steering wheel can return to the center because the tires tend to move in the direction of least resistance as the car continues to move forward, which is the straight direction. When the vehicle is in motion, the steering resistance is higher than the straight-line resistance, so the steering naturally avoids high resistance and automatically returns to the center without external force. Front wheel alignment: From the side view of the car, the kingpin axis is not perpendicular to the ground but slightly tilted backward, creating an angle known as the caster angle. This causes the intersection point of the kingpin axis and the ground to be at a distance from the wheel. During steering, the lateral force from the ground on the wheel creates a torque on the kingpin, which helps the front wheels return to the center.

That automatic steering correction function in BMW, to put it bluntly, is the Lane Keeping Assist system designed to help you make minor steering adjustments during highway or long-distance driving, keeping the car on track. It primarily relies on a camera mounted on the windshield to monitor lane markings. The moment it detects any deviation, it senses it and adjusts the steering via the electric power steering system, saving you the trouble. I've used this feature quite a few times, especially during highway driving or at night when fatigue sets in—it quietly corrects the steering, reducing the risk of veering off course. Additionally, it can work in tandem with adaptive cruise control for smoother semi-autonomous driving assistance. However, remember it's not suitable for all road conditions—it's better to turn it off in heavy city traffic to avoid interference with frequent lane changes. For maintenance, regularly clean the camera lens to prevent snow or dirt from affecting its accuracy, which could otherwise lead to misjudgments and false activations.

What are the functions of the buttons in a car?

The buttons in a car are functional controls for various configurations, typically concentrated on the central console and surrounding areas for convenient blind operation and quick access by the driver. The car's central console is usually the area with the most buttons, integrating air conditioning controls and multimedia controls. Some high-end models may use LCD touch screens to replace these buttons. Below is additional information: 1. Steering Wheel: First is the steering wheel. Generally, multi-function steering wheels integrate audio controls and dashboard information center controls on both sides. Some additional configurations may also be placed on the steering wheel. Behind the steering wheel, car light controls and wiper controls are usually integrated on separate stalks, with some models also featuring adaptive cruise control. 2. Auto Start-Stop Function: In the gear lever area, you'll typically find buttons for auto start-stop, auto hold, electronic parking brake, and ESP. The auto start-stop function is common in many models today, with the button usually located in the lever area. Auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when you need to move again. 3. Auto Hold: The main function of auto hold is to brake the vehicle when stopped without turning off the engine, keeping the car in a parked state. Simply put, it automatically engages and disengages the parking brake. 4. Electronic Parking Brake: The electronic parking brake is essentially an upgraded version of the traditional handbrake, saving time, effort, and space while being very convenient to use. Similar to the electronic parking brake is the one-button start, which is an upgraded version of the traditional key ignition, simplifying the starting process to just pressing a button while stepping on the brake. To turn off the engine, you also press the same button.

How to Maintain Bridgestone Tires?

Bridgestone tire maintenance methods: 1. Rotate tire positions every 10,000 kilometers to evenly distribute tire fatigue, avoid uneven wear, and extend tire life; 2. When driving, avoid rapid starts, emergency braking, or sharp turns; 3. It is recommended to perform a wheel alignment every 2,000 kilometers to reduce abnormal tire wear caused by changes in the main parameters of wheel alignment. Bridgestone tires are products of Bridgestone Corporation of Japan and are now widely used in various automobile brands worldwide. Bridgestone tires are currently used in products of several Chinese automobile manufacturers, including Guangzhou Honda, Tianjin FAW Toyota, Zhengzhou Nissan, and Beijing Jeep.

How many kilometers does a car generally need to be scrapped?

General scrapping mileage for vehicles: 1. Private cars, including 5-seat sedans and 7-seat SUVs, non-commercial small and mini vehicles have no usage lifespan, but the state will guide scrapping when the mileage reaches 600,000 kilometers. If the vehicle is over 15 years old and has not reached 600,000 kilometers, it needs to undergo annual inspections twice a year, and those failing the inspection will be forcibly scrapped; 2. Taxis have a usage lifespan of 8 years, and will be forcibly guided to scrap when the time is up; 3. Domestic pickup trucks are forcibly scrapped after 15 years; 4. Medium-sized taxi passenger vehicles have a usage lifespan of 10 years, and will be forcibly guided to scrap when the time is up.

How to Solve the Abnormal Noise of Door Limiters?

Solutions for abnormal noise in door limiters: 1. Check whether the design and manufacturing process are normal, and whether there are signs of rust; 2. Apply grease to the door limiter to prevent abnormal noise caused by rust or lack of lubrication. Door limiters generally refer to door opening limiters. The function of a door opening limiter is to restrict the degree to which the door can be opened. On one hand, it can limit the maximum opening of the door to prevent it from opening too wide; on the other hand, it can keep the door open when needed, such as when the car is parked on a slope or in windy conditions, preventing the door from closing automatically.

What is the function of the AC button in a car?

The function of the AC button in a car is to adjust and control the temperature, humidity, air cleanliness, and air flow inside the vehicle to a more comfortable state. The AC button is the switch for the car's air conditioning cooling system. Pressing the AC button will gradually lower the temperature inside the car. The car's air conditioning cooling system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. Car air conditioning refers to the air conditioning device installed in the vehicle, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. Different types of air conditioning systems have varying layouts, and currently, most passenger cars widely use integrated heating and cooling air conditioning systems.
