What does a variable lane mean?

Variable lane refers to a lane with multiple diagonal lines drawn on the inner side, somewhat resembling a lying-down 'non' character, which can change its direction indication at any time according to traffic flow. It is mainly designed for road sections where traffic is concentrated during peak hours but lanes are relatively few, or where there is a significant difference in traffic flow between morning and evening peak hours. When encountering such a lane, simply follow the direction indicated by the variable lane. Variable direction lanes are primarily set up at intersections, allowing flexible adjustment of traffic flow direction based on the characteristics of vehicle flow during different periods, thereby changing the driving direction of the lane to alleviate traffic pressure. They are particularly suitable for intersections that require time-based traffic management measures. The purpose of setting up such lanes is to address the vehicle flow direction at intersections with severe tidal traffic phenomena.

Why does the steering wheel need to be slightly tilted to drive straight?

The steering wheel needs to be slightly tilted to drive straight due to an issue with the adjustment of the steering tie rod angles. If the tilt angle is not significant, it can be fixed by adjusting the steering tie rod. The steering tie rod is a crucial component in a car's steering mechanism, and its condition directly affects the vehicle's handling and stability. Problems with the steering tie rod can also impact the normal operation of the tires, and in severe cases, may lead to abnormal tire wear, shortening the tire's lifespan. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver on the steering wheel's edge into torque, which is then transmitted to the steering shaft.

What is the Internet of Vehicles?

The concept of the Internet of Vehicles refers to the effective utilization of dynamic information from all vehicles in the information network platform through wireless communication technology by onboard devices in vehicles, providing various functional services during vehicle operation. The Internet of Vehicles achieves all-round network connections, including vehicle-to-cloud platform, vehicle-to-vehicle, vehicle-to-road, vehicle-to-person, and in-vehicle connections, through next-generation information and communication technologies. It primarily realizes the integration of three networks: the in-vehicle network, inter-vehicle network, and onboard mobile internet. Characteristics of the Internet of Vehicles: 1. It can ensure the distance between vehicles, reducing the probability of collision accidents; 2. It can help drivers with real-time navigation and improve traffic operation efficiency through communication with other vehicles and network systems.

What does shoulder mean?

Shoulder refers to the strip-like section with a certain width located between the outer edge of the carriageway and the subgrade edge (including hard shoulder and protective shoulder). It is used to maintain the functionality of the carriageway and for temporary parking, as well as serving as lateral support for the pavement. The main functions of the shoulder are: 1. To protect the stability of main structures such as the carriageway; 2. To provide a temporary parking space for vehicles experiencing mechanical failures or emergencies; 3. To provide lateral clearance, enhancing safety and comfort; 4. To allow passage for pedestrians and bicycles. On the pavement, the carriageway, overtaking lane, and hard shoulder are separated. The hard shoulder is constructed together with the carriageway and overtaking lane, with equal strength, and its role is to ensure the width of the carriageway and provide space for emergency parking. On highways, vehicles are not allowed to drive on the hard shoulder.

What are the benefits of waxing a car?

Waxing a car has the following benefits: 1. It makes it difficult for rainwater to adhere to the car's surface, preventing acid rain from corroding the paint; 2. The thin layer formed by waxing can reflect light, avoiding paint aging; 3. It can prevent the generation of static electricity and reduce the adhesion of charged dust to the car; 4. It serves as a polishing agent, enhancing the brightness of the paint and making the car appear newer. As a traditional item in car detailing, the primary function of car waxing is waterproofing and protection against acid rain. Due to the protection provided by the wax, the amount of water droplets adhering to the car body is significantly reduced. Wax application can be divided into manual waxing and mechanical waxing. Manual waxing is simple and easy to perform, while mechanical waxing is more efficient. Whether done manually or mechanically, it is essential to ensure even application on the paint surface.

What causes a clicking sound when turning the steering wheel?

The reasons for a clicking sound when turning the steering wheel: 1. Friction noise from the steering wheel horn electrode; 2. Noise from the steering column universal joint or the steering column rubbing against the floor mat; 3. Noise from the steering wheel return lever. The friction noise from the steering wheel horn electrode is more common in vehicles without airbags, where the steering wheel only has a horn button. Since the horn switch rotates with the steering wheel while the connecting wire below remains stationary, the wire can easily break when turning the steering wheel. Noise from the steering column universal joint or the steering column rubbing against the floor mat occurs because the front end of the steering column has a universal joint. Sometimes, lack of lubrication in the universal joint can cause a clicking sound, in which case the universal joint needs to be lubricated. The turn signal has an automatic return function. When the turn signal is on and the steering wheel is turned, the steering column hitting the return lever can produce a clicking sound.
