Prompting lane departure occurs because the vehicle is not following the route planned by the navigation system. Below is an introduction to the Lane Departure Warning System: 1. How to cancel the Lane Departure Warning System: The driver can turn it off by pressing the system's switch button, which typically features an icon of a dotted line and a tilted car. 2. Components of the Lane Departure Warning System: The system mainly consists of a HUD (Head-Up Display), a camera (usually installed on the side of the vehicle or near the rearview mirror), a controller, and sensors.

After driving for ten years, this is what annoys me the most—I always feel the system is too sensitive! In fact, lane departure warnings frequently go off mainly in three situations: when the lane markings are unclear, the camera gets confused, especially on old roads after rain or where old and new markings overlap. Also, erratic steering can trigger it—for example, I’m used to steering with one hand, and the system thinks I’m swerving. Don’t ignore tire issues either; last time, a 0.3 difference in tire pressure between the sides kept triggering warnings. Here’s a lesser-known fact: if you modify wide-body rims that extend too far beyond the body, the system’s trajectory prediction can fail. I recommend first calibrating the camera angle at the dealership and checking the chassis alignment data. If the alarm suddenly goes off on the highway, don’t panic—just grip the wheel and make slight adjustments.

How many years after purchasing a new car does it require an annual inspection?

If the new car is a small or micro non-commercial passenger vehicle, it requires an annual inspection after exceeding 6 years. Introduction to Annual Inspection: Motor vehicle inspection includes three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive vehicle performance inspection. Annual inspection, also known as annual check-up, refers to the safety inspection conducted every year or every two years on a vehicle. This includes a comprehensive check of components such as the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, etc. Annual Inspection Process: Upon arrival at the inspection station, the first step is the exterior inspection. The owner needs to park the vehicle in the designated area for exterior inspection, prepare the fire extinguisher and triangular warning sign, open the vehicle's engine hood and trunk, and wait for the staff to conduct the inspection. After payment, the owner must submit their ID card and vehicle license to the staff, who will then enter the vehicle's annual inspection information into the system. Once these steps are completed, the owner can take the form and wait for the online inspection. If the online inspection is passed, the owner can proceed to the final procedures at the general inspection office.

Why Are There Holes in the Engine Hood?

The reason there are holes in the engine hood is for heat dissipation. Some are due to high compression ratio boosting. You can open the engine hood to check what's underneath—if it's an intake partition, then it's for boosting; if it's an intercooler, then it's for heat dissipation. Airflow Guidance Function: For objects moving at high speed in the air, the air resistance and turbulence generated around the moving object directly affect its trajectory and speed. The shape of the engine hood can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the car. Through guidance, air resistance can be decomposed into beneficial forces, increasing the force of the front tires on the ground, which helps stabilize the car's movement. Protection for the Engine and Surrounding Pipeline Components: Under the engine hood are critical components of the car, including the engine, electrical circuits, oil circuits, braking system, and transmission system. These are vital to the vehicle. By enhancing the strength and structure of the engine hood, it can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the normal operation of the vehicle.

What is the engine speed of a motorcycle?

Motorcycle engine idle speed is 1400 (±100) RPM. Most domestic motorcycles have a maximum speed between 7,000 and 9,000 RPM. Some domestic motorcycles can reach up to 11,000 RPM. Tachometer working principle: Electronic tachometers utilize electromagnetic principles: a piece of iron is connected to the needle, surrounded by an electromagnetic coil. The electromagnet has three wires: positive, negative, and the high-voltage pack input wire, which is the engine's ignition wire. Each time this wire discharges, the engine ignites once, meaning the engine rotates twice. Based on this principle, every time the electromagnet is energized, it magnetizes once. The faster the rotation, the stronger the magnetic force, causing the needle to move upward. Mechanical tachometer: Mechanical tachometers use a flexible steel wire connected at one end to the engine and the other end to the instrument panel. The engine's power drives the rotation of the flexible wire. Inside, there is a circular magnet with a bowl-shaped iron disk attached to it, and the needle is mounted on the disk. The faster the rotation, the quicker the magnetic force moves the iron bowl. The principle of the mechanical tachometer is the same as that of the odometer on the left.

Can someone else handle the driver's license renewal for me?

Driver's license renewal can be handled by someone else. The process and required documents are as follows: 1. Prepare two 1-inch photos and a medical certificate, with one photo attached to the top right corner of the medical form and the other kept for the new license. 2. Bring your ID card and driver's license to the service hall, fill out the "Renewal Application Form," then submit the documents, medical certificate, and application form to the staff, pay a 10-yuan fee, and wait for the new license to be issued. 3. Before renewal, check if there are any unresolved traffic violations. If so, they must be handled first; otherwise, renewal will not be processed. 4. Renewal can be done up to 90 days in advance. Plan your time wisely to avoid expiration. If your license expires and you are caught by traffic police, you will be fined 50 yuan without any points deducted. 5. It is best to take the renewal photos and medical certificate directly at the police station's service hall, where the fee is 10 yuan for both. Otherwise, there is a risk of disqualification, requiring retakes and delaying the process. Renewal is usually completed on-site, but in some large cities, it may take a few days, though it must be completed within 15 days, after which you will be notified to collect your new driver's license.

Is an ID card required for driver's license renewal?

Yes, when applying for driver's license renewal upon its expiration, you must submit an ID card or temporary ID card; a household registration booklet cannot be used. Article 48 of the new traffic regulations stipulates: Motor vehicle drivers should apply for license renewal at the vehicle management office of the original license issuing authority within 90 days before the expiration of their driver's license. When applying, an application form must be filled out, and the following documents and certificates should be submitted: (1) The identity proof of the motor vehicle driver; (2) The motor vehicle driver's license; (3) A medical certificate on physical conditions issued by a county-level or higher medical institution or a military medical institution at or above the regimental level. For those applying for a special small automatic transmission passenger vehicle for the disabled, a medical certificate on physical conditions issued by a specialized medical institution designated by the provincial health authority must be submitted. The identity proof for residents is the 'Resident ID Card' or 'Temporary Resident ID Card'. For mainland residents living in temporary residences, the identity proof is the 'Resident ID Card' or 'Temporary Resident ID Card', along with the residence or temporary residence certificate issued by the public security authorities.

How Should Cars Be Replaced?

The vehicle replacement process involves a used car appraiser evaluating and pricing the car, while a sales consultant assists in selecting and ordering a new car. After negotiating the used car deal, a used car purchase and sale agreement and a replacement agreement are signed. The value of the old car will directly offset the cost of the new car. Once the owner pays the difference for the new car, the vehicle pickup procedures are completed. Car replacement means that regardless of the brand or age of your car, you can take it to a 4S dealership for evaluation. The old car is then exchanged for a new one. This is the replacement policy, commonly referred to as the trade-in policy. The benefits of replacement are that 4S dealerships purchase used cars according to the manufacturer's policy, making the process more formal. For consumers, buying a used car from a 4S dealership is safer, as there are no middlemen involved. The condition and quality of the used car are very transparent, eliminating concerns about not knowing how to sell a used car and getting stuck. Before the replacement policy was introduced, selling a used car first and then buying a new one was more cumbersome. Now, we only need to have the used car evaluated at a branded car dealership, where professionals can provide customers with professional and transparent vehicle evaluation and quotation services. For dealers, all procedures are convenient and fast.
