Section speed measurement is achieved through automatic license plate recognition systems. The two speed measurement points at the front and rear capture images by lane, so reducing speed can adjust your speed within the limit. During driving, comply with traffic rules and avoid speeding.

Last time I encountered a section speed control on the highway, to be honest, many people don't understand how it calculates violations. Simply put, this speed measurement takes photos of your license plate and records the time at designated point A, then does the same at point B. The system calculates your average speed based on the distance between the two points and the time taken. If the average speed exceeds the limit, say 120km/h, it's considered speeding. I remember once when I exceeded the limit, the ticket showed the exact time and speed data, plus points were deducted - a hard lesson learned. Using cruise control to maintain steady speed can help avoid this, never accelerate then decelerate midway as it won't help. The advantage of section speed control is it's fairer, preventing drivers from speeding between cameras, making roads much safer. Everyone should drive steadily.

From a technical perspective, the calculation method of interval speed measurement is quite fascinating. It captures the vehicle and time at the highway entrance camera, then takes another shot at the exit, and applies the formula: speed = distance / time difference. If this speed exceeds the speed limit, the system automatically determines a speeding violation, and the data is uploaded to the traffic management platform. I recall that the cameras rely on AI for license plate recognition and calculations, which is quite accurate. The consequences of a violation are typically a fine ranging from 200 to 500 yuan plus around 3 demerit points, affecting the next annual inspection. How to avoid it? Installing a navigation app with real-time alerts makes driving much more reassuring, and it's more reasonable than single-point speed measurement.

Interval speed measurement is designed to ensure everyone's safety by calculating violations based on average speed. Simply put, it records the time when you pass the starting point and the ending point, then calculates whether your speed exceeds the limit. This prevents drivers from slowing down only in front of cameras while speeding dangerously on the road. If you exceed the speed limit, the ticket will detail the data, including the fine and penalty points, but more importantly, it helps avoid accidents. I've seen too many accidents caused by speeding, so now when I drive, I always stay within the speed limit, using interval speed measurement to remind myself to drive steadily—safety first.

What Causes Engine Shaking During Vehicle Startup?

Here are the reasons for engine shaking when starting a car: 1. Low temperature. The temperature inside the engine is insufficient, and both the fuel and lubricating oil are not warm enough. Therefore, during a cold start, more fuel should be injected to meet power requirements. The larger the spark plug gap, the smaller the ignition energy. 2. Poor fuel atomization at low temperatures. Fuel requires higher ignition energy. After prolonged use, the ignition gap of the spark plugs tends to widen, leading to reduced ignition energy, which affects performance and causes the car to shake. Additionally, aging ignition coils, aging high-voltage wires of the spark plugs, or electrical leakage can also reduce ignition energy. 3. Incorrect air-fuel mixture ratio. The air-fuel mixture ratio may be inaccurately adjusted, occurring in both open-loop and closed-loop control systems. In cars with closed-loop control, the oxygen sensor's minimum operating temperature is 370 degrees Celsius. If the car has just been started, the exhaust pipe temperature may not reach 370 degrees Celsius, preventing the oxygen sensor from functioning. In this case, the ECU makes incorrect judgments, leading to errors in controlling the air-fuel mixture and ignition timing through the actuators. This reduces the car's power output and results in shaking.

How Often Should BYD Batteries Be Replaced?

If it is a pure electric vehicle, the battery can last for about 8 years. If it is a gasoline-powered vehicle, the battery can last for 3 to 4 years. Here is some relevant information about the battery: 1. From top to bottom, the battery pack internally consists of insulation cotton, thermal management modules, insulation materials, etc., with the battery casing on the outside. Inside, there are also water-cooled heat dissipation plates and structural supports for the battery. 2. Traditionally, cylindrical-shaped single cells were used, which left many gaps when stacked. After accounting for cooling supports and structural components, the space utilization rate was only about 40%. The flat blade battery can reduce the ineffective gaps between single cells, and the increased surface area also plays a significant role in heat dissipation. After overall arrangement, the space utilization of blade batteries can reach up to 60%.

Where is the OBD interface of Wuling Rongguang?

The OBD interface of Wuling Rongguang is located in two possible positions. One is next to the blower above the accelerator pedal, and the other is under the dashboard on the passenger side. The exact location depends on the specific model and is often very hidden, requiring a flashlight to locate. Additional information: 1. OBD, an abbreviation for On-Board Diagnostics, is an onboard automatic diagnostic system. This system monitors the working conditions of the engine's electronic control system and other functional modules of the vehicle in real-time during operation. If any abnormality is detected, it identifies the specific fault based on specific algorithms and stores the diagnostic trouble codes (DTC) in the system's memory. 2. The OBD interface is generally located on the lower left side of the steering wheel, covered by a lid that can be opened to reveal it. It has multiple functions. For example, if the car lacks a heads-up display, a heads-up display device can be plugged into the OBD interface to project all dashboard information while driving, including water temperature, fuel consumption, and speedometer readings. This is particularly useful if the car has high fuel consumption.
