What does autonomous driving level L0 mean?

Autonomous driving level L0 is entirely operated and driven by the driver. Below is an introduction to autonomous driving levels: 1. L1 level: It can assist the driver in completing certain driving tasks, such as the adaptive cruise control (ACC) function installed in many models, which uses radar to control the distance between vehicles and adjust acceleration and deceleration in real-time. This feature is widely used in many domestic models. 2. L2 level: It can automatically complete certain driving tasks and, after processing and analysis, automatically adjust the vehicle's state. For example, Tesla's lane-keeping function belongs to this level. In addition to controlling acceleration and deceleration, it can also control the steering wheel. However, the driver must monitor the surrounding environment to ensure safe vehicle operation. 3. L3 level: This level uses more logical driving computers to control the vehicle. The driver does not need to keep hands and feet on standby, as the vehicle can independently complete driving operations in specific environments. However, the driver cannot sleep or rest and must still take over when the artificial intelligence cannot make accurate judgments.

Can damaged car parts be claimed under vehicle damage insurance?

Natural wear and tear of car components is not covered under vehicle damage insurance. Only damage caused by accidents qualifies for compensation under this insurance. The coverage of vehicle damage insurance includes the following: 1. Scope of vehicle damage insurance: During the insurance period after purchasing the insurance, the insurer is responsible for compensating for accidents or natural disasters (excluding earthquakes) caused by the insured or their permitted drivers using the vehicle. If situations specified in the insurance contract occur, such as the insured or their permitted drivers driving without a license or under the influence of alcohol, the insurer may be exempt from liability. 2. Recommended groups for purchasing vehicle damage insurance: Novice drivers, new cars, and high-value vehicles: Novice drivers are more likely to be involved in accidents due to their lack of driving experience; owners of new cars generally cherish their vehicles and worry about significant damage from accidents, so both novice drivers and new car owners are advised to purchase vehicle damage insurance for protection. High-value vehicles usually have higher repair costs than ordinary vehicles. To avoid the financial burden of excessive repair costs from accidents, purchasing vehicle damage insurance helps mitigate such risks.

Can a Broken Car Trunk Lock Be Repaired?

Can a broken car trunk lock be repaired? Yes, a broken car trunk lock can be repaired. Here are some precautions regarding the car trunk: 1. Valuables: This category doesn't just refer to money but also includes any expensive items. In reality, the trunk isn't as secure as one might think. Thieves can easily open it using current technology, and people often overlook items stored in the trunk, so owners might not notice missing items until much later. 2. Flammable and explosive items: These items should not be stored in your car or any public transportation vehicles. Especially in hot summer weather, items like alcohol or lighters can explode due to high temperatures, and the consequences of ignition are unimaginable. 3. Heavy items: Some people think the car is meant to make life easier, so they frequently store items in the trunk, or like some friends who enjoy road trips, they prefer to keep luggage in the back. Heavy items not only increase fuel consumption but also cause more damage to the car tires when driving on bumpy roads due to the excessive weight.

What Causes Loud Engine Noise in BMW Vehicles?

Specific reasons include the following: 1. Engine oil issues: Engine oil can indeed cause variations in engine operating noise. In new vehicles, components within the engine cannot fully break in due to manufacturing tolerances and processes, resulting in higher internal friction. Therefore, factory-fill oil requires lower viscosity and better heat dissipation, with less emphasis on cleaning performance and oxidation resistance (rust prevention). Some factory oils even contain friction modifiers to accelerate component break-in. During the first oil change, replacing this oil with higher-viscosity formulations of different compositions will noticeably increase engine noise. 2. Carbon buildup accumulation: Carbon deposits are an unavoidable phenomenon in vehicles. Severe carbon buildup over time leads to reduced power, increased fuel consumption, and louder engine noise. During operation, impurities in gasoline form carbon deposits under high temperature and pressure. Even high-quality gasoline contains long-chain hydrocarbons that burn slowly and incompletely, inevitably forming deposits. 3. Engine mount deterioration: Worn engine mounts contribute to increased noise while introducing additional vibration and resonance issues. 4. Deteriorated sound insulation: Even with strictly standardized oil maintenance, older vehicles will subjectively sound louder primarily due to degraded overall soundproofing performance.

What are the steps for cylinder pressure testing?

Cylinder pressure testing steps: 1. Install the cylinder pressure gauge on the engine; 2. Warm up the engine to normal operating temperature, maintaining coolant temperature between 85 to 95 degrees; 3. Remove all spark plugs or injectors from the vehicle and ground the high-voltage wires; 4. Press the accelerator to fully open the throttle; 5. Screw the threaded adapter into the spark plug hole, or press the tapered rubber adapter of the cylinder pressure gauge firmly into the spark plug hole of the cylinder being tested; 6. Operate the starter for about two seconds, read the pressure value once the pointer stabilizes, then press the one-way valve button to release pressure and reset the pointer. Note: Each cylinder should be measured at least twice, taking the average value as the result. Additionally, during the second measurement, inject a small amount of engine oil (20-30ml) into the spark plug hole before retesting the cylinder pressure.
