What does autonomous driving L2 level mean?

Autonomous driving L2 level is classified as semi-autonomous driving, which enables the vehicle to operate multiple functions while requiring the driver to control a few functions. Below are two essential systems that autonomous driving L2 level must have: 1. Adaptive Cruise Control System: Also known as ACC adaptive cruise control system, the latest commercial version is the third-generation ACC adaptive cruise control system. It uses front radar sensors to collect signals and automatically follows the preceding vehicle for acceleration and deceleration. It also features the Stop-Go function, making it not only suitable for highway conditions but also ideal for urban driving. The AEB (Automatic Emergency Braking) system assists in braking when the distance to the preceding vehicle or pedestrian is less than the safe distance, helping to prevent collisions. 2. Lane Keeping System: During turns, the vehicle can easily deviate from its lane due to inaccurate steering by the driver, especially for novice drivers who have just obtained their licenses. Once the vehicle enters the opposite lane during a turn, it can be very dangerous.

What are the effects of shock absorber oil leakage?

Shock absorber oil leakage at the initial stage will not cause significant impact, as the leakage rate is relatively slow. However, over time, the lack of oil will result in the shock absorber losing its damping function. When driving, the vehicle will experience noticeable shaking and bumping (body roll), and when encountering potholes, the wheels may produce a "bang" collision sound, causing considerable damage to the vehicle's suspension. When shock absorber oil leakage occurs, it should be addressed as soon as possible. Below is relevant information: 1. The role of shock absorbers: As the most critical component in a vehicle's vibration filtering system, shock absorbers primarily absorb vibrations and impacts caused by uneven road surfaces during driving, thereby providing a comfortable driving and riding environment for vehicle occupants. 2. The hazards of damaged shock absorbers: Once a shock absorber is damaged, it will greatly affect the driving comfort of the vehicle, and in severe cases, it may even pose a safety hazard. 3. Whether to replace a leaking shock absorber: Regarding whether a leaking car shock absorber can be left unreplaced, the key factor is the severity of the leakage. If it's only a minor seepage, replacement may not be necessary; however, if the shock absorber is leaking severely, it should be replaced promptly.

What are the differences between two-wheel drive and four-wheel drive vehicles?

The differences between two-wheel drive and four-wheel drive vehicles are as follows: 1. Performance differences: Four-wheel drive vehicles have outstanding power and strong off-road capability, making them suitable for off-road driving. Four-wheel drive vehicles can distribute the engine's power to all four wheels, significantly improving the vehicle's handling and passage ability. Four-wheel drive systems are mostly found in SUV models. Two-wheel drive vehicles balance urban commuting and off-road driving, with two wheels driving the vehicle. Two-wheel drive vehicles are further divided into front-wheel drive and rear-wheel drive. Rear-wheel drive is more common in performance cars, while front-wheel drive is more common in family cars. 2. Structural principle differences: As the name suggests, two-wheel drive vehicles have only two wheels responsible for driving the vehicle. Front-wheel drive means the two front wheels are responsible for driving, while rear-wheel drive means the two rear wheels are responsible for driving. Four-wheel drive vehicles are further divided into natural four-wheel drive, full-time four-wheel drive, and part-time four-wheel drive. Natural four-wheel drive means all four wheels have driving functions, full-time four-wheel drive means all four wheels are always in driving state, and part-time four-wheel drive means the driver can manually switch between four-wheel drive and two-wheel drive.

Which oxygen sensor is faulty when P0420 code appears?

P0420 refers to the failure or low efficiency of the three-way catalytic converter, indicating potential issues with either the catalytic converter or the oxygen sensor. Here are the details: 1. Troubleshooting P0420: When this occurs, check for signs of aging in the three-way catalytic converter. If the converter shows no aging, the issue likely lies with the oxygen sensor. If the oxygen sensor is faulty, try soaking it in toilet cleaner to remove carbon deposits. If the sensor still doesn't function properly after this, replacement is necessary. 2. Solutions for P0420 code: This code may indicate two possibilities - aging/blockage of the three-way catalytic converter or oxygen sensor failure. Inspect the catalytic converter's condition; if blocked, clean it, or replace if severely aged. For oxygen sensor issues, either clean or replace it. 3. Importance of oxygen sensors: These sensors are crucial for vehicles. By analyzing exhaust oxygen concentration, they monitor engine performance. A faulty sensor leads to increased fuel consumption, reduced power, and excessive emissions. All modern vehicles have oxygen sensors, which are consumable parts requiring periodic cleaning or maintenance.

What does HDC system failure refer to?

HDC system failure refers to a malfunction in the Hill Descent Control system. The HDC Hill Descent Assist system operates under the conditions of descending a slope at low speed. If a failure occurs when these conditions are not met, the vehicle can still continue to operate based on physical mechanical principles, but it is recommended to repair it promptly. HDC (Hill Descent Control) is also known as the Hill Descent Control System HDC, which enables the driver to smoothly navigate steep downhill sections without pressing the brake pedal, maintaining full control. As needed, the braking system automatically controls each wheel to move forward slightly faster than walking speed, allowing the driver to focus entirely on steering. There are two main reasons why the Hill Descent Control warning light comes on in a vehicle. The first reason is related to issues with the power drive bus's wiring or a node within it, which can be diagnosed using a computer diagnostic tool to read the fault code. The second reason is poor circuit contact inside the gateway, leading to low network voltage, which requires replacing the gateway to resolve the issue.

What Causes Vehicle Shaking?

Causes of car shaking can be divided into the following situations: 1. During startup: Shaking occurs due to insufficient vehicle power caused by incomplete fuel combustion; 2. During idling: Shaking is caused by severe engine carbon deposits, ignition system issues, or unstable oil pressure; 3. At high speeds: Shaking results from either excessively high or low tire pressure, abnormal tire wear, rim deformation, shock absorber failure, or tire dynamic imbalance; 4. Other scenarios: Fuel supply system malfunctions leading to unstable oil pressure can easily cause inconsistent mixture concentration, resulting in shaking; aging engine mounts are also a common cause of shaking.
