What is the Difference Between Blind Spot Monitoring and 360-Degree Surround View?

The differences between blind spot monitoring and 360-degree surround view lie in their application scenarios, operating durations, and detection ranges. The specific distinctions are as follows: Different application scenarios: Blind spot monitoring is primarily used during driving to eliminate blind spots in rearview mirrors, assist with lane changes, and provide alerts for potential hazards during lane changes. On the other hand, 360-degree surround view utilizes monitoring cameras around the vehicle to display real-time images of the surroundings. Different operating durations: Blind spot monitoring automatically activates when the vehicle speed exceeds 20 km/h and continuously monitors the surroundings, providing real-time alerts about blind spots to enhance safety during lane changes. In contrast, 360-degree surround view is mainly used when navigating narrow alleys, passing through width-restricted areas, or during parking, resulting in relatively shorter operating durations. Different detection ranges: Blind spot monitoring typically detects objects within 10 meters behind the vehicle. Due to the larger blind spot areas of vehicles, radar detection technology is employed, offering a wide detection range. Meanwhile, 360-degree surround view focuses on measuring the distance between the vehicle and obstacles with high clarity and accuracy, requiring a detection range of approximately 60 centimeters around the vehicle body.

What is the reason why the booster pump makes noise intermittently when not in use?

The booster pump makes noise intermittently when not in use because there is a problem with the water return seal of the pump. Generally, the structure of the pump is relatively compact, and there is a switch inside the pump. The switch is controlled by the water flow in the pipe. As long as the water in the pipe is flowing, the booster pump will be activated, resulting in the noise problem. Below are the relevant precautions: Precaution 1: The motor coil is equipped with a safety protector. If the pump fails or cannot draw water, causing the motor temperature to exceed the specified value, it will automatically cut off the circuit. After troubleshooting and the motor temperature drops, it can automatically resume operation. The booster pump motor is a capacitor-run motor. The rotation direction has been adjusted when the pump leaves the factory. If you need to replace the capacitor or rewire, please connect the wires according to the arrow direction marked on the pump body. To ensure safety, be sure to use a three-core safety socket with a ground wire. Precaution 2: If water leakage is found in the pump, stop the machine immediately to check and prevent internal leakage. If there is water leakage at the connection with the motor, replace the mechanical seal. Check whether the power supply is connected. Ensure that the power supply voltage matches the working voltage of the pump.

How Many Kilometers Should a Car's Air Filter Be Replaced After Driving?

According to the vehicle's maintenance manual, the car's air filter element should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter element every 5,000 kilometers to reduce the formation of throttle sludge. The location of the car's air filter element depends on the intake form and the engine structure, typically located in the air filter on the engine intake pipe. There are two types of air filters in cars: dry and wet. The dry type is made of paper or organic materials, while the wet type is made of metal mesh. The function of the air filter element is to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder and preventing floating dust in the air from being sucked into the engine, which accelerates the wear of the piston group and cylinder. Air filter element: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. Using an excessively dirty air filter while driving can cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must maintain a clean air filter. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities in the air before it enters the cylinder, reducing early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must pass through the fine filtration of the air cleaner. An excessively dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if it is found to have little dust and minor blockage, it can be cleaned by blowing high-pressure air from the inside out and continue to be used. Excessively dirty air filters should be replaced promptly.

What is the Scrapping Period for General Vehicles?

Non-commercial vehicles and commercial vehicles have different scrapping periods, as detailed below: Scrapping Regulations for Non-commercial Vehicles: For household 5-seat cars and 7-seat SUVs, as well as small and micro non-commercial vehicles, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. In addition to the above vehicles, small and micro non-commercial passenger cars, large non-commercial cars, and wheeled special machinery vehicles also have no usage period limit. Common Scrapping Regulations for Commercial Vehicles: Small and micro taxi passenger cars have a scrapping period of 8 years, medium-sized taxi passenger cars have a scrapping period of 10 years, and large taxi passenger cars have a scrapping period of 12 years. Public transport passenger cars have a scrapping period of 13 years, other small and micro commercial passenger cars have a scrapping period of 10 years, and large and medium-sized commercial passenger cars have a scrapping period of 15 years. Micro commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, Scrapping Approval Application Form" in duplicate and affix the owner's seal. The registration office accepts the application and issues a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, the motor vehicle inspection office will determine if they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if they do. The owner chooses a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company dismantles the vehicle and takes photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the chassis must be cut. The owner submits the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and vehicle dismantling photos to the motor vehicle inspection office for verification and signature. The license plates are then recycled, and the scrapping registration is processed according to regulations. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of motor vehicle registration, the original owner can apply to use the original license plate number when registering a new vehicle. The application must meet the following conditions: (1) The application must be made within six months after the transfer or cancellation; (2) The owner must have owned the original vehicle for more than three years.

What are the reasons for the ABS light in a Polo being on?

ABS light being on can indicate various conditions, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and calculating the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections in the system wiring or poor contact in the ABS relay, leading to system malfunction. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently turns on, but turns off during acceleration. Cause: When multiple electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and voltage rises, the ABS light turns off. This may also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor wiring connection in the ABS hydraulic valve body; ABS control unit failure. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR control unit. State 4: ABS warning light turns on during high-speed driving. Cause: During high-speed driving, the ABS control unit detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently turns on. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage all the way down, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. The illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.
