What Does Level 4 Autonomous Driving Mean?

Level 4 autonomous driving refers to high-level autonomous driving that can achieve the entire driving process without any driver intervention, but it also has certain limitations, such as restricting the vehicle speed to a certain limit and operating within relatively fixed driving areas. It generally relies on real-time updated road information data to support functions like automatic vehicle pickup/return, automated platooning, and obstacle avoidance in real-world driving scenarios. In the SAE Levels of Driving Automation published by SAE International (Society of Automotive Engineers), besides Level 4 autonomous driving, there are five other levels. Level 0 is manual driving, where, according to SAE's definition, the driver fully controls all operations including steering, braking, and acceleration. The vehicle only executes commands, so this level is not considered autonomous driving. Level 1 is driver assistance, where the driver still needs to operate the vehicle, but safety systems like ACC (Adaptive Cruise Control) provide assistance. The driver must keep hands on the wheel and eyes on the road. Features such as adaptive cruise control, lane-keeping assist, and automatic braking in luxury brands like Volvo and Mercedes-Benz fall under Level 1 autonomous driving. Level 2 is partial automation, where the vehicle can simultaneously control acceleration/deceleration and steering, meaning adaptive cruise control and lane-keeping systems can work together. Most automakers have already achieved Level 2 autonomous driving technology. Level 3 is conditional automation, where the vehicle can autonomously handle acceleration, deceleration, and steering in specific environments without driver input or monitoring of surroundings. However, the driver must remain attentive and ready to take over if the system encounters unmanageable situations. The Audi A8 is the world's first production car capable of Level 3 autonomous driving on public roads. Level 5 is full automation, requiring no driver intervention under any conditions. It can operate in all weather and geographic conditions, allowing the driver to focus on rest or other tasks. However, legal and technological breakthroughs are still needed before widespread adoption. Autonomous driving demand analysis: The essence of autonomous driving technology is to replace human labor with artificial intelligence in specific scenarios, improving efficiency and reducing labor costs. Its underlying logic is similar to industrial robotics' "machines replacing humans," profoundly impacting industries like transportation, logistics, and commercial services. Thus, labor cost savings directly reflect the economic value of autonomous driving. All vehicles that do not require human operation fall under autonomous driving. Based on scenario openness, speed (divided by 20 km/h), and cargo type, autonomous applications can be categorized into open/closed, high/low-speed, and passenger/cargo dimensions. High-speed open-road autonomous driving is the most challenging and promising, attracting top-tier companies, but commercialization remains distant. In contrast, limited-scenario autonomous applications have lower technical barriers and faster commercialization. Fully manual driving models are rare, with Tesla being one example. The market categorizes driving modes into six levels: L0 (manual), L1 (assisted), L2 (partial automation), L3 (conditional automation), L4 (high automation), and L5 (full automation). Currently, the highest commercially available level is L2, which still requires human oversight for safety.

How is Carbon Deposit Formed?

Carbon deposits primarily result from incomplete combustion of fuel in the engine or non-combustible paraffin and gum substances in gasoline. These residues remain in components such as fuel injectors, throttle valves, fuel lines, and spark plugs, transforming into carbon deposits under high temperatures. Symptoms of carbon buildup in the vehicle's intake system include: elevated idle speed, abnormal idle vibration, poor acceleration response, increased fuel consumption, and excessive exhaust emissions. During engine operation, sticky residues produced by incomplete combustion of the air-fuel mixture form carbon deposits that adhere around the cylinder head and spark plugs, impairing normal cylinder function and reducing engine performance.

How to Set the Time and Date on a Dash Cam?

To set the time on a dash cam: Press the 'M' button on the dash cam to enter the menu, then navigate to General Settings > Time Settings to make adjustments. It's important to note that the dash cam should ideally be powered by the car battery to prevent time inaccuracies due to power loss. A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. Once installed, it can capture the entire driving process in video and audio, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also document challenging journeys. Essentially, it continuously records while driving, capturing time, speed, and location data in the footage, functioning much like a black box for your car.

What are the items for the first car maintenance?

Items for the first car maintenance include: 1. Inspection of car lighting, including emergency signal lights, trunk lights, glove box lights, indicator lights, dashboard warning lights, and passenger compartment lights; 2. For car tires, it is necessary to check the wear condition and the tire pressure. If the tire pressure is insufficient, professional repair shops should be visited for maintenance and inspection; 3. Inspection of the fuel pipe lines, dust covers, rubber protective parts at the bottom, and the fixation of the car chassis. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing.

What is an automobile frame?

An automobile frame is the base structure of a vehicle, also known as the chassis. It bears almost all the weight of the vehicle and cargo, typically consisting of two longitudinal beams and several cross beams. It is supported on the wheels via suspension devices, front axle, and rear axle, possessing sufficient strength and stiffness to withstand the vehicle's load and impacts transmitted from the wheels. The automobile frame is primarily a major load-bearing component inside the vehicle, directly affecting driving safety. Deformation of the frame is mainly characterized by bending. Therefore, frame plates have high requirements for formability, meaning the steel plates used for automobile frames must have excellent comprehensive performance, sufficient strength and toughness, good fatigue resistance, and cold formability.

How often should car batteries be replaced?

Car batteries generally need to be replaced every 3 to 5 years. It is recommended that owners check the battery's internal resistance and voltage during each maintenance service. If both the internal resistance and voltage fail to meet the specified values, it indicates that the battery needs replacement. The battery is a crucial component of a vehicle, powering all electronic devices when the engine is not running, and it is also responsible for starting the engine. After the engine starts, it drives the alternator to operate, which then supplies power to electronic devices and recharges the battery. Car batteries, referring to storage batteries, are an indispensable part of automobiles and can be categorized into traditional lead-acid batteries and maintenance-free batteries.
