What is the difference between L2 and L3 autonomous driving?

L2 and L3 have certain differences in the level of autonomous driving. The following are the distinctions between L2 and L3 in terms of autonomous driving capabilities: 1. L2 Level: L2 achieves semi-autonomous driving, where the vehicle can perform multiple functions, allowing the driver to take brief breaks from steering but still requires readiness to take over driving tasks at any time. L2 features include full-speed adaptive cruise control, automatic parking, active lane keeping, speed limit recognition, automatic lane changing, etc. 2. L3 Level: L3 enables the vehicle to perform partial autonomous driving operations in specific environments, capable of determining whether to continue autonomous driving or return control to the driver based on road conditions. This level marks the true beginning of autonomous driving, where the vehicle can almost independently complete all driving operations, even allowing the driver to browse social media like Weibo.

How Severe Are the Effects After a BMW 5 Series Drives Through Water?

The severity of the effects after a BMW 5 Series drives through water mainly depends on the extent of damage to the car's engine. If the water level does not reach the doors, the impact is generally minor. Below is some extended information about BMW: 1. Full Company Name: The full name is die Bayerischen Motorenwerke (Bavarian Motor Works). Over the past century, BMW has evolved from an aircraft engine manufacturer into a corporate group that specializes in premium cars and also produces world-renowned aircraft engines, off-road vehicles, and motorcycles. 2. Strategic Partnerships: In June 2020, the joint venture between Great Wall Motors and BMW, Spotlight Automotive, began piling construction in Zhangjiagang, Jiangsu, to produce MINI electric vehicles. On July 27, 2020, BMW signed a digital cooperation agreement with Tencent. Features from Tencent's Automotive Intelligent System (TAI), such as the in-car light application ecosystem 'Tencent Mini Programs' and 'WeChat Onboard,' will be integrated into BMW vehicles.

What is the minimum ground clearance of the Envision S Avenir?

The minimum ground clearance of the Envision S Avenir is 196 millimeters. The minimum ground clearance of the Envision S Avenir refers to the distance between the lowest point (excluding the wheels) and the supporting plane, which indicates the vehicle's ability to pass over obstacles such as rocks and tree stumps without collision. A higher ground clearance for the Envision S Avenir improves its off-road capability, but if the ground clearance is too high, the stability at high speeds may decrease. Compared to models like the CR-V, which is already in its fifth generation, the Envision appears relatively young. It first debuted as the ENVISION concept car in 2011 and entered mass production in 2014, making its appearance at the Chengdu Auto Show in August of the same year. Like previous new models from SAIC-GM, the Pan Asia Technical Automotive Center (PATAC), a joint venture between General Motors and SAIC, was deeply involved in the development of this new vehicle. It can be said to be a "domestic" car among joint-venture vehicles. The Envision S Avenir measures 4,662 millimeters in length, 1,883 millimeters in width, and 1,631 millimeters in height, with a wheelbase of 2,779 millimeters. Generally, the ground clearance for sedans ranges between 110 millimeters and 150 millimeters, while SUVs typically have a ground clearance between 200 millimeters and 250 millimeters. However, the ground clearance of the Envision S Avenir is not static; it also depends on the load condition. Therefore, changes in the vehicle's load should be considered when evaluating ground clearance. When selecting a vehicle, ground clearance can be one of the reference factors. The choice depends on the vehicle's intended use and the road conditions. For urban driving on well-paved roads, a vehicle with lower ground clearance may offer better stability and comfort. For those frequently traveling to remote areas or driving on rough terrain, a vehicle with higher ground clearance is advisable to enhance off-road performance and avoid damage to the undercarriage.

How Often Should Rear Brake Pads Be Replaced?

Conventional brake pads typically need replacement every 25,000 to 30,000 kilometers. Below are relevant details: 1. Impact of Automatic vs. Manual Transmission: Automatic transmissions wear out brake pads faster than manual transmissions because gear shifting relies on the accelerator and brake pedals. 2. Regional Influence: Vehicles frequently driven in urban areas experience faster brake pad wear compared to those mainly driven on highways. This is due to frequent stop-and-go traffic in cities, requiring more brake usage, whereas highway driving may cover dozens of kilometers before needing to slow down or stop, resulting in fewer braking opportunities. 3. Effect of Vehicle Load: Heavier vehicles cause greater brake pad wear. When decelerating at the same speed, a heavier vehicle has greater inertia, requiring more friction force from the brake pads, leading to increased wear.

How is the space performance of the five-seater Envision Plus?

The body size of the Envision Plus makes it a top performer in the midsize SUV market. Even as a five-seater version, it offers impressive rear-seat comfort. The trunk is also spacious, with the second-row seats capable of fully folding down to create a large storage area. Below are the relevant details: 1. Exterior: The 2020 Buick Envision appears more rugged and bold. The new wing-shaped chrome trim runs through the LED wing-shaped headlights, widening the horizontal visual effect. The dynamic bumper surfaces and three-dimensional silver lower guard create a full and powerful front end. The rear also adopts a three-dimensional wing-shaped design, with chrome trim connecting the taillights, paired with integrated dual exhaust pipes to enhance the sporty feel. 2. Interior: The Envision continues Buick's consistent high-quality interior standards and introduces a newly designed 10-inch HD touchscreen to elevate the technological feel. The vehicle also features front-row multifunction seats, adjustable and sliding rear seats with reclining backrests, a large split central storage box, a heated steering wheel, and a two-piece oversized panoramic sunroof.

What Causes the Air Conditioning Not to Start When the Car Interior Temperature is High?

The reasons why the air conditioning does not start when the car interior temperature is high are as follows: 1. When using the air conditioning: The engine operates under high load conditions, and the air conditioning compressor increases the engine load. 2. Condenser: The condenser requires a cooling fan for forced heat dissipation, so the engine temperature is one of the important parameters of the air conditioning system. 3. Engine control unit: When the engine temperature is too high, the engine control unit will cut off the ground terminal of the air conditioning compressor relay to reduce the temperature by reducing the engine load. More information about excessively high engine temperature is as follows: 1. Blockage: System dirt blockage, internal blockage of the radiator tank. Machine blockage, such as a malfunctioning or damaged thermostat, or a malfunctioning water pump. 2. Malfunction: Air lock, engine malfunction causing high pressure in the cylinder to enter the cooling system. Poor heat dissipation, low cooling fan speed. Damaged fan shroud, dirty radiator surface. Cars with electric fans have a cooling fan activation device.
