What does Level 4 autonomous driving mean?

L4 autonomous driving refers to high-level autonomous driving, which can achieve the entire driving process without any driver operation, but there are also certain restrictions, such as limiting the vehicle speed to not exceed a certain value and having a relatively fixed driving area. It generally relies on real-time updated road information data support to achieve real-world scenarios such as automatic vehicle pickup and return, automatic convoy cruising, and automatic obstacle avoidance. The following is an introduction to autonomous driving levels: 1. Level 1 driving automation: The driving automation system continuously performs lateral or longitudinal motion control of the vehicle within its designed operating conditions and has the ability to detect and respond to some targets and events corresponding to the performed lateral or longitudinal motion control. 2. Level 2 driving automation: The driving automation system continuously performs both lateral and longitudinal motion control of the vehicle within its designed operating conditions and has the ability to detect and respond to some targets and events corresponding to the performed lateral and longitudinal motion control. 3. Level 3 driving automation: The driving automation system continuously performs all dynamic driving tasks within its designed operating conditions. 4. Level 4 driving automation: The driving automation system continuously performs all dynamic driving tasks and takes over dynamic driving tasks within its designed operating conditions. 5. Level 5 driving automation: The driving automation system continuously performs all dynamic driving tasks and takes over dynamic driving tasks under any drivable conditions.

How to Deal with Water in the Cabin?

To address water in the cabin, open several sealing rubber plugs located at the bottom of the vehicle chassis to drain the accumulated water. Below are additional details: 1. Interior materials like floor mats have strong water absorption properties. Remove the floor mats and place them in a spacious area to facilitate water evaporation. 2. Water in the cabin often contains dirt and mud. On sunny days, first remove and air out detachable interior items such as foot mats and seat covers for cleaning. 3. For carpets that are not too dirty, use a vacuum cleaner directly. For dirtier carpets, use specialized cleaning agents. 4. If the cabin is severely flooded or retains a persistent musty smell after drying, the issue may lie beneath the floor lining where the sponge has absorbed moisture and become moldy. Visit a professional auto repair shop to remove the seats and floor lining for thorough cleaning to eliminate the musty odor.

Will the interior of the 2022 Audi Q2L change?

Some aspects of the 2022 Audi Q2L's interior will change, while others will remain the same. The 2022 Q2L is equipped with a 12.3-inch 'Audi Virtual Cockpit' and an 8.3-inch central multimedia touchscreen. The interior center console retains the touch and MMI knob operation methods, paired with a three-spoke flat-bottom multifunction sports steering wheel, enhancing the overall technological feel. Below is an extended introduction: 1. Exterior: The front fascia of the new model features a large polygonal grille with a rectangular mesh pattern, and the air intakes on both sides of the bumper have been redesigned into a triangular shape, increasing its distinctiveness. Additionally, the Matrix LED headlights adopt a matrix design, incorporating seven independent LED smart modules that enable intelligent high and low beam functionality. 2. Side Profile: The new model continues with a bold waistline design, complemented by front and rear fenders and black protective panels, highlighting its SUV off-road characteristics. The new Q2's C-pillar maintains the black decorative panel design, paired with a white logo for added fashion appeal. Furthermore, the new model will offer wheel sizes ranging from 16 to 19 inches. 3. Powertrain: Overseas models will introduce two new gasoline engines, a 1.0T and a 2.0T. The 1.0T engine delivers a maximum power of 110 horsepower, labeled as 30TFSI, and is paired with a 6-speed manual transmission. The 2.0T engine produces a maximum power of 190 horsepower, labeled as 40TFSI, and is matched with a 7-speed dual-clutch transmission featuring a four-wheel-drive system. Additionally, the overseas models will continue to offer the 1.5T engine as an option.

What is a Gasoline + 48V Mild Hybrid System?

Gasoline + 48V mild hybrid system is a more efficient hybrid power system. Here is an introduction to the gasoline + 48V mild hybrid system: The 48V mild hybrid system with a power system can assist the vehicle during startup, using electric power during the most fuel-consuming startup process to effectively save fuel. Additional information: 1. The battery life of a 48V mild hybrid system generally exceeds 5 years. The 48V mild hybrid system uses a 48V battery, which is significantly higher in cost and technology compared to 12V systems. The 48V mild hybrid system mainly consists of a motor, battery, and voltage converter. 2. The 48V system currently primarily uses lithium-ion batteries. Compared to conventional lead-acid batteries, these lithium batteries have larger capacity and faster charging. However, the 48V battery is relatively expensive, so when choosing a vehicle with a 48V mild hybrid system, attention should be paid to battery maintenance.

How to Check the Condition of a Compressor?

Compressor's resistance between RS equals the sum of SC and RC resistances, which can be used to determine its condition. Below are extended details: 1. To assess the compressor's condition, first identify its three terminals: S, R, and C. S is the start winding, R is the run winding, and C is the common terminal. 2. Then, use a multimeter to measure the resistances. The sum of SC and RC resistances should equal the RS resistance under normal conditions. 3. If the resistances deviate significantly or show no reading between any two terminals, the compressor is damaged. 4. Even if the multimeter readings appear normal, internal short circuits may not be detected. A simple method is to check for power using the multimeter. If power is present but the compressor doesn't start, replace the start capacitor.
