What is the Basic Principle of Car Movement?

The basic principle of car movement is that the torque from the engine is transmitted through the drivetrain to apply a driving torque on the drive wheels, attempting to make them rotate. Below are some key points to note for car movement: 1. Normal roads: There is no specific requirement for the gear; you can drive normally by keeping the car in D (Drive) mode. 2. Parking: When the engine stops, shift the gear to P (Park) to indicate the car is no longer in use. Some cars require shifting to P to remove the key. 3. Reversing: After the car stops moving forward, shift to R (Reverse) and gently release the brake to move backward. 4. Waiting or driving in traffic: You can shift to N (Neutral). 5. Highways or overtaking: You can shift to S (Sport) mode. S mode is the car's sport setting, allowing free gear changes like D mode. It is also useful for climbing hills, as it provides maximum torque output and acceleration.

What's the matter with maintenance-free battery not charging?

Maintenance-free battery not charging may be due to internal disconnection or short-circuit damage. Maintenance-free batteries cannot be refilled with liquid as they lack refill ports. If the battery shows poor charge retention or fails to hold charge after charging, replacement is the only option. For maintenance-free batteries, adding electrolyte is not recommended as it disrupts internal mechanisms - the proper approach is regular charging. Two solutions: 1. Use a smart charger with activation mode. 2. Charge by connecting it in parallel with another charged battery. Additional details: 1. Maintenance-free batteries produce minimal gas during normal charging, feature strong overcharge resistance, low internal resistance, excellent cold-start performance, and longer lifespan than conventional batteries. 2. They require no distilled water refills during service life and need no supplemental charging when the charging system functions properly, though electrolyte specific gravity should be checked during maintenance.

Can I get my car inspected without an ID card?

An ID card is not required for the annual inspection, so you can have your car inspected without one. Here are some details about the annual inspection: 1. For the annual inspection, you only need to bring your vehicle license and compulsory traffic insurance policy. 2. Before the annual inspection, any traffic violations must be settled; otherwise, the inspection cannot be passed. 3. During the inspection, your car needs to be driven onto the inspection line where professionals and specialized equipment will examine the vehicle. 4. The inspection includes checks on the car's appearance, exhaust emissions, chassis, braking system, and lighting system. 5. When checking the lighting system, special attention is paid to the brake lights, reverse lights, and turn signals. 6. If the car's appearance has been modified, it must be restored to its original condition before the inspection; otherwise, it will not pass. If the annual inspection is overdue and you are caught driving without it, you may face fines and penalty points.

What's the Difference Between 360-Degree Surround View and Rearview Camera?

The difference between 360-degree reverse camera and rearview camera lies in the number of cameras and the system configuration. The rearview camera typically uses only one camera, while the 360-degree surround view system generally employs 4 to 6 cameras. The rearview camera is primarily used for reversing to monitor the road conditions behind the vehicle, whereas the 360-degree surround view system not only assists in reversing but also helps in parking by displaying the surroundings of the car on the vehicle's screen. More details are as follows: 1. The 360-degree surround view system is a parking assistance system that provides a 360-degree panoramic view of the car's surroundings on the vehicle's display screen, offering a wide-angle, seamless, and real-time image (bird's-eye view). This system helps drivers understand blind spots around the vehicle, making parking more intuitive and safer. It is also known as the panoramic parking imaging system. 2. The 360-degree surround view system installs four wide-angle cameras around the car to cover all viewing angles. These cameras process multiple video feeds simultaneously into a single 360-degree overhead view of the vehicle, which is then displayed on the central control screen, effectively eliminating all visual blind spots around the car.

What is the braking distance of a car?

Under normal circumstances, the braking distance of a car traveling at 100 kilometers per hour is between 38-42 meters. If the value exceeds this range, it indicates poor performance of the car's braking system, and it should be checked at a professional auto repair shop promptly. Braking distance is one of the key parameters to measure a car's braking performance. It refers to the distance traveled by the vehicle from the moment braking begins until the car comes to a complete stop when the vehicle is at a certain speed. It is the distance covered by the car from the instant the driver presses the brake pedal hard until the car stops completely at a certain speed. It includes two parts: reaction distance and braking distance. The shorter the braking distance, the better the braking performance of the car. According to the national standards GB-12676 and GB/T-13594, the braking distance of cars has the following requirements: for passenger cars with fewer than 9 seats and an initial speed of 50Km/h, it should not exceed 19m. For other vehicles with a total mass of less than 4.5t and an initial speed of 50Km/h, it should be less than 21m. For other cars and car trains with an initial speed of 30Km/h, it should not exceed 12m. The length of the braking distance is an important factor in determining whether the braking system of the car is working properly. The heavier the car, the greater the inertia, and the more powerful the braking system it needs. Of course, due to the exceptionally strong power of some supercars, their braking systems are also top-notch. For family cars, the time from 100 kilometers per hour to a complete stop is generally about 3 seconds, but the distance can be as long as 40 meters. Tests have shown that among the cars on the market, the BMW 530i has the most outstanding braking distance, reaching 37.8 meters. Some cars require 46 meters from 100 kilometers per hour to 0, which, although in compliance with national safety standards, in critical moments, a car with an excellent braking distance can save the owner's property and even life.

What are the highway lane markings?

Highway lane markings include the following types. Channelizing lines: Vehicles must not straddle or park on them. According to laws and regulations, channelizing lines are a type of prohibited marking. Vehicles must follow the designated route and are not allowed to drive over or cross these lines, nor make U-turns or park in the channelizing area. Lane dividing lines: Dashed lines can be crossed, but solid lines cannot. Lane dividing lines are used to separate traffic flows moving in the same direction. They are generally divided into white dashed or solid lines or yellow dashed or solid lines. White dashed lines separate lanes moving in the same direction, allowing lane changes or overtaking when safe. White solid lines also separate lanes moving in the same direction but prohibit lane changes. For dashed-solid lines, lane changes are allowed on the dashed side but not on the solid side. Transverse and longitudinal deceleration markings: Pay attention to controlling speed and decelerate appropriately. Transverse deceleration markings are groups of white lines perpendicular to the road centerline, used to indicate the need to slow down. They are commonly found on curves, downhill sections, and tunnel entrances. Longitudinal deceleration markings are diamond-shaped dashed lines parallel to the lane dividing lines, creating a visual sense of pressure to prompt drivers to slow down. Distance confirmation markings: Maintain a safe following distance. On highways, large green distance signs (e.g., 0m, 50m, 100m, 200m) are clearly visible along the roadside, helping drivers determine the distance to the vehicle ahead. Highway lane markings (white dashed lines) are 6 meters long with 9-meter gaps between them (referred to as "6-9 lines"). The total distance of two lines plus the gap is 21 meters. Drivers can estimate distance using these markings—10 gaps equal approximately 150 meters. Escape ramp markings: For emergency use in case of vehicle malfunction. If a driver finds their vehicle's brakes failing, they can steer onto an escape ramp. Escape ramps are typically 50 to 100 meters long and sloped, covered with a thick layer of gravel to increase tire friction. Tires are piled at the entrance and end to absorb impact and help stop the "out-of-control" vehicle. Emergency lane: Life-saving lane; prohibited for non-emergency use. The emergency lane, also known as the "life lane," is reserved for emergency vehicles such as engineering rescue, firefighting, medical ambulances, or police performing urgent duties. All other vehicles are prohibited from entering. Speed limit markings: Article 67 of the Road Traffic Safety Law states: "Pedestrians, non-motor vehicles, tractors, wheeled special machinery vehicles, articulated buses, full trailers, and other motor vehicles with a maximum design speed of less than 70 kilometers per hour are not allowed on highways. The maximum speed limit indicated by highway speed limit signs must not exceed 120 kilometers per hour." Red signs indicate the maximum speed limit, while blue signs indicate the minimum speed limit.
