Car distance sensors are installed at the rear of the vehicle. The distance sensor consists of components such as ultrasonic sensors, controllers, and displays or buzzers. The distance sensor, also known as a displacement sensor, is a type of sensor used to detect the distance between it and an object to achieve a preset function. The car distance sensor is used in adaptive cruise systems to detect the distance between the vehicle ahead and the host vehicle. It enables follow-up functionality by accelerating or decelerating based on the speed of the vehicle ahead. Car distance sensors are connected in series to form an alarm circuit. When one of the reversing radar distance sensors fails or is removed, the entire alarm circuit is in a broken state, and the entire reversing alarm system will sound an alert when activated.

I previously installed distance sensors on my own car, typically mounted on the front or rear bumper, specifically embedded in the plastic trim near the license plate or corners. For a sedan like mine, several ultrasonic sensors are installed on both the front and rear bumpers to detect obstacles during reversing or parking. You should note that the installation points must avoid obstructions, such as stickers or dirt buildup, which can affect accuracy. I recommend cleaning the bumpers every six months, avoiding direct water spray on the sensor areas to prevent short circuits. Different car brands may have slightly different placements; for example, some SUVs also place sensors on the sides to adapt to more complex road conditions. In short, the design considers safety and usability, and if the sensors malfunction, you should check for loose or damaged installations.

The placement of those little car distance sensors is quite particular. They are commonly installed in the front and rear bumper areas—for example, radar sensors are usually centered in the front, while ultrasonic parking sensors are scattered around the corners. Having driven multiple models, I've noticed that some imported cars even integrate the sensors into the bumper design, making them visually more discreet. The key is that their positioning directly affects detection range—placing them closer to the edges minimizes blind spots, ensuring safer parking. During installation, durability must also be considered; avoid mounting them too low to prevent water splashes from interfering in rainy conditions. For maintenance, it's recommended to regularly check cable connections and avoid modifications that could trigger false alarms. There's a significant difference between older brand models and new energy vehicles, as the latter often integrate more advanced technology.

Distance sensors are typically installed on the inner side of the bumper, with several at the front and rear, evenly distributed to ensure full coverage without blind spots. From my experience in car repairs, the bottom of the rear bumper is often the main location, facilitating the operation of the reversing radar. This position is chosen because it's close to the vehicle's structure, ensuring stability and minimal vibration. For maintenance, avoid impacts and clean with a soft cloth, being careful not to block the sensor points. New car designs also take aerodynamics into account, adjusting sensor positions to optimize response time.

What Issues Should Be Noted When Buying a Used Electric Vehicle?

When purchasing a used car, the inspection mainly revolves around the vehicle's condition, such as the power battery, electrical system, and other aspects. When selecting a used new energy vehicle, due to its different structure, it is difficult to check the actual condition of some key parts without professional equipment and personnel. Extended information is as follows: 1. Inspection of the power battery: The core of a new energy vehicle's power is the power battery. The quality of the power battery directly affects the vehicle's range. Additionally, since replacing the power battery is very expensive, it is one of the key points during the inspection. 2. Motor, electronic control, and electrical system: A major cause of spontaneous combustion in new energy vehicles is faults in the electrical and electronic control systems. To avoid purchasing a vehicle with safety hazards, it is best to have a comprehensive inspection by a 4S shop, just like with the power battery. 3. Other inspections: For example, whether the steering wheel pulls to one side, whether there are abnormal noises when driving on bumpy roads, and whether the chassis is loose. Additionally, ensuring the completeness of the vehicle's documents is a routine check to rule out major accidents, repaired vehicles, water-damaged vehicles, and to verify the functionality of various vehicle components.

Does High-Pressure Water Gun Car Washing Damage the Car?

Yes, it does. High-pressure water gun car washing can damage the car paint. When using a high-pressure water gun, excessive water pressure and improper operation can easily cause sand and stones on the car to scratch the surface, leading to abnormal wear of the paint. If the paint is already slightly damaged, the high-pressure water gun can enlarge the damage or even wash away wax, crystal coatings, or protective films. Here are some precautions for car washing: 1. Pre-washing is crucial: Cars often have a lot of dust and mud. Before washing, it's important to add a pre-wash step, which involves using professional equipment to spray a special pre-wash solution on the car body and waiting for one or two minutes. After soaking, most of the dirt will detach from the paint, making it safer to rinse with the water gun. 2. Follow a proper washing sequence: Start with areas that have less dust and mud, such as the roof, hood, and trunk lid. Cleaning from top to bottom helps prevent scratches, and always scrub in the same direction. 3. Choose the right water temperature: After driving for a while, the car is in a high-temperature state, and using cold water to wash it at this time is not advisable. Even if the car hasn't been driven for long but has been exposed to sunlight for a significant time, washing it immediately with cold water can cause the paint to age due to thermal expansion and contraction.

Why do large vehicles stop and then start again when turning right?

This is mainly to remind motor vehicles, non-motorized vehicles, and pedestrians behind and to the right of large trucks to maintain a sufficient safe distance when turning right and avoid being too close. Below is an introduction to automatic transmissions for large vehicles: 1. Introduction: Automatic transmission usually refers to the automatic gear-shifting mechanism of a vehicle. 2. Operation: While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear-shifting operations. 3. Details: Generally, automatic transmission vehicles have six gear positions, from top to bottom: P, R, N, D, S, L. The most commonly used automatic gear positions are Park (P), Reverse (R), Neutral (N), and Drive (D).

What Causes the Rattling Noise from the Passenger Side?

This type of rattling noise usually occurs in areas with many plastic components, such as the dashboard or the inner door panels. Especially when driving on uneven roads, the vehicle body may vibrate or slightly twist due to road bumps, causing these internal plastic parts to resonate and produce rattling noises or friction sounds from squeezing against each other. Common causes of car rattling noises: 1. Tire noise: Tire noises are rhythmic, and the frequency increases with speed. A dull "thudding" sound often indicates tire tread deformation, bulging, severe wear, or insufficient air pressure. A "clicking" sound may suggest small stones stuck in the tread. If the tire produces a roaring noise accompanied by noticeable body shaking or steering deviation, it could indicate a tire blowout. 2. Transmission noise: If there is a "grinding" sound from the transmission while driving, which disappears when the clutch is pressed, it suggests a transmission issue, possibly due to worn transmission bearings or gears, or bearing spots.
