What is the principle of automatic wiper sensing?

The principle of automatic wiper sensing mainly involves the use of sensors. Currently, the two widely used mainstream sensors are optical sensors and capacitive sensors. Principle of Optical Sensor: Optical sensors operate based on the principle of light refraction. In an optical sensor, there is a light-emitting diode that emits a conical beam of light, which passes through the front windshield. When there is no rain on the windshield and it is dry, almost all the light is reflected onto an optical sensor. When it rains, water accumulates on the windshield, causing some of the light to deviate. This results in a change in the total amount of light received by the sensor, thereby detecting the presence of rain. The larger the area of reflected light that the optical sensor can receive, the more detailed the information obtained. Optical sensors are highly precise and can even accurately determine the number of raindrops falling on the sensing area. Principle of Capacitive Sensor: This primarily utilizes the significant difference in dielectric constants between water and glass. The dielectric constant of water is 80, while that of glass is 2. Two parallel finger-like metal plates are placed between the inner and outer layers of the windshield, with one set of finger-like metal plates interleaved but not touching the other set. When the windshield is dry, a dielectric is formed between the outer surface of the windshield and each set of finger-like metal plates. When the windshield becomes wet, the dielectric constant of the windshield changes differently depending on the amount of water in contact with it.

Why Are Yellow Cars Unpopular?

Yellow is too bright. Here are some suggestions for choosing car colors: 1. Sunny weather: Under clear weather conditions, light-colored cars have better visibility and higher color safety, while black cars have the highest accident rate. 2. Twilight: Accident statistics during twilight hours comparing color safety show that light-colored cars have better visibility, lower accident rates, and higher driving safety, while black cars not only have lower visibility but also higher accident rates. 3. Bright and dark colors: Red and yellow are bright colors, while dark-colored cars appear smaller, farther away, and more blurred. Bright colors have better visibility. From a safety perspective, cars with good visibility colors are preferable. Some colors with poor visibility can also be improved with reasonable combinations, such as blue and white, which significantly enhance the effect.

Is It Normal for Car Wheels to Rust?

It is normal for the steel rims inside new car tires to develop surface rust, as they are made of cast iron and this generally does not affect their normal use. Many car models use aluminum alloy for wheel hubs. The advantage of aluminum alloy is its strength and durability, but the downside is its vulnerability to acid. Aluminum can easily oxidize when exposed to acid, and if placed in a strong acidic environment, aluminum alloy wheels can indeed corrode. Analysis of the causes of steel rim rust: 1. Quality issues with the wheel hub: Many car manufacturers have improved their processes to reduce the harm of acidic substances to aluminum alloy wheels. It should be noted that the vast majority of car wheels today are essentially resistant to acid. However, a few models still have wheels that are prone to corrosion. 2. Careless driving leading to severe scratches on the wheel hub surface: Damage to the protective varnish on the wheel hub surface exposes the aluminum alloy material to the air, causing oxidation and corrosion. Therefore, it is important to drive carefully and avoid scraping against curbs.

What is the difference between temporary suspension and detention?

Below are the differences between temporary suspension and detention: 1. Definition: Detaining a motor vehicle driver's license refers to an administrative compulsory measure taken by traffic police during the execution of their duties; temporarily suspending a motor vehicle driver's license refers to a penalty method where the traffic management department of the public security authority legally suspends the motor vehicle driving qualification of a road traffic law violator for a certain period. 2. Duration: The duration of detaining the driver's license of a violator is until the day the public security authority legally imposes an administrative penalty; for the penalty of temporarily suspending a motor vehicle driver's license, the driver's license should be transferred to the vehicle management office of the issuing location within 15 days after the penalty decision, and the driver's license should be returned according to the prescribed procedures after the temporary suspension period expires.

Does starting the car with the air conditioning on have any impact on the vehicle?

Yes, it has an impact. When the engine starts, the air conditioning compressor also operates, placing a significant load on the battery and affecting its lifespan. Here are some precautions for using the car air conditioning: 1. Avoid using the air conditioning for too long in a single session: If the interior temperature has reached a comfortable level, you can turn off the air conditioning or turn it on again after a while. Prolonged use of the air conditioning can increase the pressure on the condenser, causing wear and tear to the cooling system. Therefore, it is advisable not to use the air conditioning for extended periods each time. 2. Ventilate by opening windows: When you first enter the car, you should open the windows for ventilation and turn on the external circulation to expel the hot air. 3. Do not use the internal circulation of the air conditioning for too long: Since internal circulation involves the air circulating within the enclosed space of the car, the oxygen level inside the car will continuously decrease. Additionally, if the gasoline in the cylinders does not burn completely, unburned carbon monoxide from the engine may leak into the cabin. As a result, the air quality inside the car will deteriorate and may even pose a health hazard.

What to Do When Running Out of Gas in a Traffic Jam on the Highway?

It is recommended to pull over, turn on the hazard lights, and then call the insurance company's roadside assistance for fuel delivery. Drive the car to the emergency lane, park it, set up a triangle warning sign, and then call a towing company for assistance with towing, etc.
