What is the Concept of a Two-Way Four-Lane Road?

Two-way four-lane road: There are a total of four lanes in both directions. For example, there are two lanes heading east and two lanes heading west, making it a two-way four-lane road. According to the relevant national standards, the width of each lane on urban roads is 3.75 meters, diversion lanes at intersections are 2.3-2.5 meters per lane, trunk roads (including highways) have a lane width of 3.75 meters, and shoulders (emergency stopping lanes on highways) are 1.5-3.5 meters wide. Different types of two-way four-lane roads: 1. Two-way four-lane highway: Designed for speeds of 60-80 km/h, with a road width of four lanes. A median strip and green belt can be set up in the middle, with each lane being 3.75 meters wide. When necessary, a non-motorized vehicle lane of over 3.5 meters and a sidewalk of over 4 meters must be established. 2. Two-way four-lane expressway: Designed for speeds of 80-120 km/h, with a road width of four lanes and two emergency lanes. A median strip is set up in the middle, using high-grade pavement such as asphalt concrete or cement concrete, equipped with complete signs, markings, signals, and lighting devices; pedestrians and non-motorized vehicles are prohibited from walking on the road, and intersections with other routes are designed as overpasses, pedestrian bridges, or underpasses.

Introduction to Haval Big Dog Features

Here is the detailed introduction about Haval Big Dog: 1. AEB Autonomous Emergency Braking: This driving assistance solution eliminates the millimeter-wave radar in hardware, relying on powerful visual algorithms to achieve many functions, but it may be unreliable in some extreme situations, which the industry refers to as "corner cases". 2. RCT Rear Cross Traffic Alert/Braking: The Haval Big Dog is equipped with two BSD blind spot detection radars at the rear, supplied by Bosch, operating at 77GHz frequency. 3. APS Automatic Parking Assist: Capable of identifying both perpendicular and parallel parking spaces, with recognition technology based on a fusion algorithm of visual cameras and ultrasonic sensors.

Can Four-Wheel ATVs Be Licensed?

Four-wheel ATVs theoretically cannot be licensed because they are currently not allowed on public roads in China. In our country, there are no laws or regulations permitting ATVs to be driven or licensed on roads, and this vehicle type is not included in the official catalog. Moreover, ATVs are clearly classified as four-wheel motor vehicles, making it impossible to exploit loopholes like electric bicycles to operate them on roads. Additional information: 1. International situation: In some foreign countries, ATVs are explicitly defined as special vehicles that can only be used in designated areas, and driving them on public roads is illegal. Other countries, such as France, clearly allow ATVs on roads, but the vehicles must meet specific conditions, including turn signals, rearview mirrors, reflectors, and compliant headlights. 2. Domestic exceptions: Through certain methods and channels, it is still possible to get ATVs on the road. However, actual conditions vary by region, and the interpretation and enforcement of policies differ.

What are the key points to observe when reversing into a parking space from the right?

When reversing into a parking space from the right, pay attention to the following 3 key points: 1. Position of the right rear wheel and the corner line of the parking space: While reversing, carefully observe the right side mirror. When the mirror shows that the rear wheel is about to cross the corner line of the parking space, quickly turn the steering wheel fully to the right. 2. Distance between the rear wheel and the right corner of the parking space: Monitor the distance between the rear wheel and the right corner of the parking space. If the distance is exactly 30cm, there is no need to adjust the direction; simply continue reversing. If the distance is less than 30cm, you can turn the steering wheel halfway back to maintain a distance of about 30cm. 3. Whether the car body is parallel to the side line of the parking space: Observe the side mirror carefully. When the car body is parallel to the side line of the parking space, quickly straighten the steering wheel. If the alignment is uneven, make slight adjustments following the principle of 'steering towards the wider side.'

What is a Dual Clutch?

Here is an introduction to dual clutches: 1. Overview: The clutch is located between the engine and the transmission, serving as the 'switch' for power transfer from the engine to the transmission. It is a transmission mechanism capable of both transmitting and cutting off power. Its primary function is to ensure smooth vehicle starts, reduce impact loads on transmission gears during gear shifts, and prevent overload in the drivetrain. 2. Structure: The DSG transmission mainly consists of a multi-plate wet dual clutch, a three-shaft gear transmission, an automatic gear-shifting mechanism, and an electronically controlled hydraulic control system. The most innovative core components are the dual clutch and the three-shaft gearbox. 3. Principle: Structurally, the DKG is composed of two sub-transmissions, each equipped with a clutch. Clutch 1 is connected to sub-transmission 1, and clutch 2 is connected to sub-transmission 2.

Reasons for the Rapid Discontinuation of the Geely Xingyue L

Reasons for the rapid discontinuation of the Geely Xingyue L are as follows: 1. Insufficient brand influence: Although Geely has become a top-tier domestic automotive brand, there is still a significant gap compared to joint-venture brands. The final price of the Geely Xingyue 2.0T model is already comparable to that of competing models in the same segment, such as the Honda CR-V, Toyota RAV4, and Nissan X-Trail. Despite these vehicles having fewer features than the Xingyue, many consumers still prioritize joint-venture brands due to their brand appeal. 2. Limited rear-seat space: The Geely Xingyue features an exaggerated fastback design, which greatly enhances its visual appeal—viewed from the side or rear, it can even evoke the illusion of a BMW X6. However, the trade-off for this stylish design is reduced interior space. The headroom in the rear seats of the Geely Xingyue is relatively cramped, leading to a sense of confinement when fully loaded, resulting in poor comfort performance.
