What Principle Does the Reversing Radar Utilize?

The principle of the reversing radar system involves the use of ultrasonic signals. Controlled by the microcomputer within the reversing radar host, the signals are emitted and received by the probes. By comparing the signal return time, the system calculates the distance to obstacles and then issues different alarm sounds via the alarm device. Below is a detailed introduction to the reversing radar system: 1. The reversing radar system consists of the reversing radar ECU, the reversing radar buzzer, and several (usually four) reversing radar sensors installed on the (rear) bumper. If a rear camera is installed, it provides an image of the rear area of the vehicle on the navigation screen. 2. When the vehicle is shifted into reverse gear, the reversing radar ECU monitors the area around the rear bumper using ultrasonic sensors. If an object is detected within the monitored area, the audible alarm device in the instrument cluster will sound a warning. The system can detect relatively hard solid obstacles as well as objects like wire mesh and fences. 3. The detection range of the two side sensors covers an area 60cm from the corners of the bumper. When the detected distance is less than 20cm on the sides or less than 30cm directly behind the center, the sound signal will become continuous to prevent a collision with the bumper.

What does the rear button in a car mean?

Rear refers to the rear windshield defogger. Pressing it removes fog from the rear windshield. Typically, the rear defogger switch automatically turns off after about ten minutes to protect the heating filaments. If the defogging effect is unsatisfactory after activating the rear defogger, it may be due to aging from prolonged use. Here is additional information: 1. Representation: The literal meaning of 'rear' is the back or rear part. In cars, the rear button appears in the air conditioning system and functions as the rear windshield defogger. However, many car models now omit the 'rear' label and simply use an icon. 2. Heating filaments: On the rear windshield of a car, you can see copper wires, which are heating filaments. Pressing the rear button activates these filaments to heat and defog the rear windshield. Usually, the rear defogger switch turns off automatically after about ten minutes to protect the heating filaments. In fact, many car models now also feature a front windshield heating system.

What is the Difference Between a Streaming Media and a Dash Cam?

Streaming media and dash cams mainly differ in terms of cost and performance, size, lifespan, and installation process. Below is a detailed introduction to these four differences: Cost and Performance: The cost of a streaming media rearview mirror is higher than that of a dash cam. At the same time, streaming media supports simultaneous front and rear recording. Streaming media also requires higher processor and memory card capacity compared to dash cams. Size: Streaming media devices are larger in size, while dash cams are more compact. Streaming media may interfere with the use of the driver's sun visor. Lifespan: The lifespan of a streaming media rearview mirror is longer than that of a dash cam. This is because dash cams are usually exposed outside the vehicle and are more prone to damage. Installation Process: The installation process for a streaming media rearview mirror is more complex than that of a dash cam. Installing streaming media requires wiring.

Which Areas Need Soundproofing Treatment in a Car?

Car soundproofing is most effective when applied to the engine, four doors, and chassis. However, car soundproofing must be done systematically and comprehensively; focusing on just one area cannot achieve the most effective soundproofing quality. Below is a detailed introduction to car soundproofing: Partial Soundproofing vs. Full-Car Soundproofing: Full-car soundproofing offers the best results but is the most expensive, while partial soundproofing is the most economical. Hiring a Professional Team for Car Soundproofing: DIY modifications not only consume a lot of time but also yield inferior results compared to professional teams. Noise and Soundproofing: Car noise is categorized into low, medium, and high frequencies. Not all noises can be blocked. Medium- to high-frequency noises, such as engine noise, can be soundproofed. Tire noise, especially exhaust pipe sounds, falls under medium- to low-frequency noise and is difficult to isolate.

How to Charge a Plug-in Hybrid Electric Vehicle at Home?

Plug-in hybrids can be charged at home by using the included portable charging cable, plugging it into a standard 220V single-phase three-pin AC household socket. Below is an introduction to related content: 1. A plug-in hybrid is a type of new energy vehicle that falls between a pure electric vehicle and a traditional fuel-powered car. It features both a conventional car's engine, transmission, drivetrain, fuel system, and fuel tank, as well as the battery, electric motor, and control circuitry of a pure electric vehicle. 2. Characteristics of plug-in hybrid vehicles: They can be externally charged. Even when the battery is depleted, the engine can drive the generator to recharge the battery. Plug-in hybrids still primarily rely on traditional fuel as their main power source, with the electric motor serving as an auxiliary power source. 3. Plug-in hybrid vehicles are categorized into: (1) Traditional internal combustion engine drive: Uses fuel consumption to obtain driving power. (2) Electric drive: Uses power from the battery to obtain driving force.

What Are the Maintenance Methods for an Automotive Generator?

Daily maintenance of an automotive generator primarily involves cleaning and inspection tasks. Cleaning: The heat generated during the generator's operation is cooled by the fan behind the pulley blowing air into the casing. Removing accumulated dirt and dust from the generator's exterior helps maintain clear ventilation channels for effective heat dissipation. Checking and Adjusting Belt Tension: The alternator is driven by the engine via a belt, and the belt tension should be properly adjusted. If the belt is too loose, it may slip, leading to insufficient power generation. Conversely, if the belt is too tight, it can cause belt damage and excessive wear on the generator bearings. To check belt tension: In a static state, apply 50N of force at the midpoint of the belt. If it deflects by 10~12mm, the tension is appropriate. Inspecting Wiring: Ensure the connections between the generator and the regulator are secure and in good contact. If there is any corrosion, promptly clean it with sandpaper. Similarly, any oxidized wires should be cleaned without delay.
