Which Light to Use When Overtaking?

Overtaking requires turning on the right turn signal. Here are some precautions for overtaking: 1. Pay attention to road conditions: When overtaking, it is essential to be mindful of the road conditions. Avoid overtaking on curves, especially when the vehicle ahead is a large truck. Large trucks have significant inner wheel differentials, and their drivers often have limited visibility. Therefore, when overtaking a large truck, make sure to use the right turn signal and maintain a sufficiently high speed to avoid prolonged parallel driving. 2. Rainy or foggy weather: Overtaking is also not advisable in rainy or foggy conditions due to very low visibility. It can be extremely dangerous to overtake when the road ahead is unclear.

What is the use of vehicle networking and what are its functions?

Vehicle networking is a vast interactive network composed of information such as vehicle location, speed, and route. Through devices such as GPS, RFID, sensors, and camera image processing, vehicles can collect information about their environment and status. In terms of functions: 1. It is equipped with an ECU (Electronic Control Unit) and an OBD (On-Board Diagnostics) system, which are responsible for monitoring and diagnosing the vehicle's operating status in the vehicle networking system. Combined with an intelligent vehicle system, it can achieve partial control of the vehicle, such as intelligent parking, adaptive cruise control, active collision prevention systems, etc. 2. Enables vehicle-machine interconnection. Internationally, systems like Apple CarPlay and Android Auto are representative, while domestically, Baidu Carlife is a notable example. These systems can project smartphone content onto the vehicle's screen, enhancing flexibility and extensibility, and aim to transform the in-car audio-visual entertainment experience. 3. Enables autonomous driving. The China Association of Automobile Manufacturers has proposed a five-stage classification for vehicle networking: Stage 1 to Stage 5 are: driving resource assistance stage, partial automation stage, conditional automation stage, high automation stage, and full automation. All of these are achieved through vehicle networking. Now, do you understand the uses and functions of vehicle networking?

At what water depth will the engine take in water?

Water entering the engine can occur at a depth of 20 cm. Here are the relevant details: 1. Ways water enters the engine: First, due to the low position of the engine intake pipe entrance, water can be sucked into the engine when the vehicle is fording. Second, if the exhaust outlet is below the waterline, water can be drawn into the engine through the exhaust pipe during fording. 2. Consequences of water entering the engine: The engine will inevitably stall after taking in water. Since water in the cylinders lacks lubricating properties, attempting to restart the engine blindly after stalling may lead to severe cylinder damage, resulting in engine failure.

What Does Low Rolling Resistance Tire Mean?

Low rolling resistance tires refer to tires that do not affect braking performance. Here are the relevant details: 1. Differences between low rolling resistance tires and traditional tires: The tread pattern, sidewalls, and dimensions of low rolling resistance tires differ from those of traditional tires. These tires have a larger diameter (covering more distance per rotation) and a narrower width (reducing contact area with the ground). 2. Definition of low rolling resistance tires: Low rolling resistance tires are a technological innovation driven by increasingly stringent passenger vehicle emission standards (or fuel consumption limits) in the EU and the US. According to the EU's 2020 passenger vehicle emission standards, the average CO2 emissions across a car manufacturer's product line must not exceed 95 grams per 100 kilometers.

Does ETC Need to Be Connected to Power?

ETC devices come in two types: solar-powered and wired charging. Solar-powered ETC devices do not require charging, while wired charging ETC devices need to be charged using a charger. Both types of ETC electronic tags have internal batteries. Solar-powered ETC devices do not need charging during daily driving, and their lithium batteries typically last for 3 years under normal use. However, for those who do not frequently use ETC, it is recommended to charge the ETC device every 3 months to effectively mitigate the impact of natural battery discharge on its lifespan. ETC stands for Electronic Toll Collection, which is an electronic toll system. To apply for ETC, the following documents are required: the original and photocopy of the vehicle owner's valid ID card and driving license. If the application is made by a proxy, the proxy's valid ID card is also required. The photocopy of the driving license should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed. Applicants must be between 18 and 60 years old, and the vehicle must be registered under an individual's name. For company vehicles, the required documents include: an introduction letter from the vehicle owner (with official seal), a photocopy of the organization code certificate or business license (with official seal), the original ID card of the proxy, the original driving license of the vehicle, and the vehicle that needs to be equipped with ETC. ETC works by communicating with the microwave antenna in the ETC lane at toll stations through an on-board electronic tag installed on the vehicle's windshield. It uses computer networking technology to settle payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay tolls. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing the frequency of starting and braking. Users can also enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC more advanced and technologically superior. Compared to license plate payment, ETC technology is more mature and advantageous.

Can the car be driven when the positive and negative terminal lights are on?

When the positive and negative terminal lights are on, the car should not be driven as it indicates a malfunction in the vehicle's charging system. The possible causes for this issue are as follows: 1. Generator Belt: If the generator belt is aged, carbonized on the surface, or has insufficient tension, it may slip and produce abnormal noises, causing the generator to lose rotation and triggering the warning light. 2. Damaged Generator Bearing: A damaged generator bearing can lead to idling, and the rotor and stator of the generator may come into contact and friction, resulting in overheating. In such cases, the bearing needs to be replaced. 3. Battery Connection Wires: If the battery connection wires are loose or corroded, they should be reconnected securely if they are loose or improperly connected. If the wires are corroded, they need to be replaced.
