Currently, both domestic and international standards classify autonomous driving into 5 levels. Below is the relevant introduction: Introduction: From L1 to L5, most cars worldwide are currently at L1 level, with only a few, such as Tesla, reaching L2 level and continuously improving. Autonomous vehicles: Also known as driverless cars, computer-driven cars, or wheeled mobile robots, autonomous vehicles are intelligent cars that achieve driverless operation through computer systems. They have a history spanning several decades in the 20th century and showed trends approaching practicality in the early 21st century. Autonomous vehicles rely on artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems working together to enable computers to operate motor vehicles safely and automatically without any human intervention.

As a tech-savvy car user, let me share my understanding of autonomous driving level classification. Defined by SAE International, it consists of six levels. Level 0 is the most basic, representing traditional driving where steering wheel and throttle are entirely human-operated without any assistance features. Level 1 introduces some automation, like adaptive cruise control that helps adjust speed, but steering still requires human control. Level 2 combines more functions, such as lane keeping plus automatic braking – many consumer vehicles like Tesla's Autopilot operate at this level, though drivers must remain vigilant and ready to take over. Level 3 marks significant progress with conditional automation, where the system can temporarily handle driving in specific environments like highways, but requires rapid human response if anomalies occur. Level 4 achieves high automation, enabling vehicles to navigate autonomously in designated areas like urban streets – Waymo's test vehicles exemplify this. The pinnacle is Level 5, representing full self-driving capability where no human intervention is needed, making it as relaxing as riding a taxi. These levels involve not just technology but also regulations and safety, with varying global adoption paces. Currently in China, most vehicles are transitioning between Levels 2 and 3, so it's crucial to carefully examine ADAS specifications when purchasing cars and not get overly swayed by marketing claims.

Will the traffic police check modified front splitters and side skirts?

If you file the modification with the vehicle management office, the traffic police will not check it. Installing front splitters and side skirts is considered an exterior modification. Here is some additional information: 1. Reasons for modification: Many car modification enthusiasts like to install front splitters and side skirts on their cars. After installation, the car's chassis appears lower, and it also enhances the vehicle's appearance. Some front splitters can even serve an aerodynamic function, as can some side skirts. 2. Preventing damage: When installing front splitters and side skirts, it is essential to go to a professional shop to ensure they are securely installed. If you have installed these modifications, you must be cautious when driving on rough, unpaved roads. Some car owners even opt for carbon fiber front splitters, which can be costly to replace if damaged. Front splitters are highly susceptible to damage during daily use, so careful consideration is necessary before installation.

Why is there no sound when playing music despite the Bluetooth being connected in the Buick Excelle?

The Buick Excelle's Bluetooth is connected but there is no sound when playing music due to the multimedia volume on the phone not being turned on, incompatibility between the music playback program and certain car models' pairing codes, the car's Bluetooth multimedia music not being enabled, or signal interference from the Bluetooth function. If the volume on the car's navigation system or the phone is not turned on, there will be no sound from the car's Bluetooth. Simply increase the volume on both devices. Some phones (such as the iPhone) have music playback programs that are incompatible with certain car models' pairing codes, allowing only phone calls but not music playback. It is recommended to switch the Bluetooth playback frequency band to resolve this issue. The car's Bluetooth multimedia music is not enabled. Locate the multimedia option on the screen, enter it, and select Bluetooth for music playback. The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. Go to the phone's Bluetooth settings, disable the media audio, and keep the phone audio enabled.

When driving, should I press the clutch or the brake to slow down?

When driving, to slow down, first gently press the brake to reduce speed, then press the clutch when the engine RPM drops below 1000 to prevent the car from stalling. Below are some related introductions about slowing down: 1. Emergency braking: In emergency situations where the vehicle needs to be stopped in the shortest distance and time, do not consider unnecessary factors like engine braking. Simply press both the clutch and brake pedals to the floor simultaneously. This cuts off all engine power while the vehicle's ESP and ABS systems allow the wheels to move in a semi-rolling, semi-sliding state, maximizing traction to bring the vehicle to a stop. 2. Deceleration at 30km/h or below: You can directly press the clutch and use the brake to slow down. At lower speeds, the gear is also lower, and the engine's traction force is relatively strong. Therefore, pressing the clutch cuts off the power; if you don't release the clutch while slowing down, it might cause the engine to stall.

Can I Buy a Car in Guangzhou and Register It in My Hometown?

It is possible to purchase a car in Guangzhou and register it in your hometown. Here are the relevant steps: 1. Vehicle Selection: Buy the car at a 4S dealership in the chosen city. 2. Temporary License Plate: Prepare a temporary license plate, which can be obtained from the car dealer or purchased separately, to present during traffic police inspections. However, be sure to note the validity period of the temporary plate, as using an expired one may result in insurance claims being denied. 3. Insurance: Contact an insurance agent in your location before departure and provide the vehicle's VIN (before the new car is registered, basic insurance can be purchased by registering the VIN) to purchase compulsory traffic insurance, third-party liability insurance, and vehicle damage insurance, among other major coverage items. 4. Copies: Prepare the original and a copy of the vehicle's certificate of conformity, the original purchase invoice (in triplicate), the owner's ID card, and the insurance policy. With these documents, you can proceed to the local vehicle management office for inspection, payment of the vehicle purchase tax, license plate selection, and registration procedures.

Where is the oil filter located on the Mercedes-Benz A180L?

The oil filter on the Mercedes-Benz A180L is located at the front left side of the engine. The oil filter, also known as the oil filter element, is responsible for filtering the oil to keep it clean, ensuring that the oil can provide sufficient lubrication to the engine. It also affects the oil change interval. If not replaced for a long time, it can accelerate engine wear. Impact of the oil filter on the car: If the oil filter is not replaced for an extended period, the flow performance of the lubricating oil will significantly decrease, restricting the flow of the engine oil pump. Over time, this can lead to excessive wear of internal engine components. Therefore, the oil filter must be replaced regularly based on actual conditions. Precautions for replacing the oil filter: Using low-quality oil or pairing high-quality oil with a low-quality oil filter is a mistake. When changing the oil, the oil filter must also be replaced. To distinguish between genuine and counterfeit oil filters, a comprehensive assessment should be made based on the housing, filter element, and filter paper.
