What Level is Autonomous Driving L3?

1 Answers
VanGiselle
07/29/25 4:44pm
Autonomous Driving L3 represents the fourth level of vehicle autonomous driving technology, which is categorized into six levels from L0 to L5. The definition of Autonomous Driving L3 is as follows: the driver no longer needs to keep hands and feet on standby, as the vehicle can independently perform almost all driving operations. However, the driver must still remain attentive to handle situations that the artificial intelligence might not be able to manage. During autonomous driving, the autonomous system and the driver do not share responsibility, adhering to relevant regulations. Whenever the autonomous system encounters road conditions it cannot handle, multiple effective notifications ensure a safe and smooth handover between the autonomous system and the driver.

What Does 'Turning the Wheel' Mean?

Turning the wheel refers to controlling the steering wheel to direct the vehicle's tires in a specified direction. Car tires are one of the most critical components of a vehicle, as they directly contact the ground and work in conjunction with the suspension system to absorb shocks during driving, ensuring a comfortable ride and smooth handling. They also maintain good traction between the wheels and the road. Below are the key functions of car tires: 1. Supporting the vehicle's entire weight: Car tires bear the full weight of the vehicle, handle the load, and transmit forces and moments in other directions. 2. Enhancing vehicle performance: Tires transmit traction and braking torque to ensure strong adhesion between the wheels and the road, improving acceleration, braking, and off-road capability. They also work with the suspension to absorb shocks and dampen vibrations. 3. Preventing premature wear of vehicle components: Tires protect vehicle parts from excessive vibrations and early damage, adapt to high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.

What is the ground clearance of the Lynk & Co 01?

The minimum ground clearance of the Lynk & Co 01 is 211mm when unloaded and 170mm when fully loaded. Ground clearance refers to the distance between the ground and the lowest rigid component of the vehicle. A car's ground clearance varies depending on whether it is unloaded or loaded. Ground clearance is related to the vehicle's load; the heavier the load, the smaller the ground clearance. Advantages of high ground clearance: The main advantage is that higher ground clearance provides better off-road capability. Additionally, vehicles with higher ground clearance generally offer the driver a better field of vision, improving the view of the surroundings. The downside is that increased ground clearance raises the vehicle's center of gravity, which can reduce stability at high speeds. Advantages of low ground clearance: The main advantage is that lower ground clearance naturally lowers the vehicle's center of gravity, making it relatively safer and more stable when driving on roads. This is especially beneficial for highway driving, where safety is enhanced. The downside is reduced off-road capability and a higher risk of scraping the undercarriage. The choice depends on the vehicle's intended use and road conditions. Generally, for urban driving on well-paved roads, a vehicle with lower ground clearance can improve stability and comfort. For long-distance travel or driving in areas with poor road conditions, a vehicle with higher ground clearance may be preferable to avoid undercarriage damage, considering its off-road performance. The specific choice should be made based on individual needs.

What is the maximum speed during the car break-in period?

During the break-in period, the car's speed should not exceed 100 kilometers per hour. More information about the car break-in period is as follows: 1. The break-in period of a new car is essentially about conditioning the performance of the car's engine and allowing the driver to adapt to the vehicle. This period also involves the driver getting accustomed to the car. Therefore, it's advisable not to drive too fast during the break-in period to avoid potential hazards. 2. Typically, the break-in period for a car ranges from 1,000 to 1,500 kilometers. However, different manufacturers may have specific guidelines for various models. The break-in period for the car's wheels and brake pads is approximately 200 to 300 kilometers. During this time, it's recommended to drive on roads with good surface conditions and to practice early and gentle braking. 3. The engine's break-in period is about 1,000 kilometers. For the first 500 kilometers, maintain a speed between 60 to 70 kilometers per hour, keeping the engine RPM below 2,200. From 500 to 1,000 kilometers, you can increase the speed to around 90 kilometers per hour, keeping the RPM steady at about 2,500. After reaching 1,000 kilometers, you can further increase the speed to 120 kilometers per hour, maintaining a stable RPM of around 3,000.

How to Check the Battery Level of Haval Big Dog?

Haval Big Dog uses a maintenance-free battery, which does not have an indicator. Its general service life is four years, with an optimal period of two years. If there is a color indicator, it is located at the top of the battery with a small glass window. Green indicates the best condition, blue is good, and red indicates poor condition. More relevant information is as follows: 1. Battery Inspection: Battery inspection mainly focuses on two data points—voltage and starting current. It is best to conduct the inspection when the engine is cold (overnight is even better). The voltage must be higher than 12V. Checking the voltage can be done easily by yourself using a multimeter by touching the positive and negative terminals of the battery. 2. Battery Charge: After replacing the battery, the new battery may not be fully charged, including the original battery in a brand-new car, which might not be at 100% charge. Therefore, after installing a new battery or purchasing a new car, it is advisable to let the engine run for a longer time to ensure the battery is fully charged.

Attend traffic law training: If a motor vehicle driver accumulates 12 points within a scoring cycle, the traffic management department of the public security authority shall detain their motor vehicle driver's license. The driver must attend a seven-day training on road traffic safety laws, regulations, and related knowledge at the traffic management department of the public security authority where the driver's license was issued or where the violation occurred within 15 days. 2. Take the exam: After completing the training, the vehicle management office shall conduct a test on road traffic safety laws, regulations, and related knowledge within 20 days. If the test is passed, the points will be cleared, and the motor vehicle driver's license will be returned. If the test is not passed, the driver must continue with the training and retake the exam.
