What does ABS mean when it appears in a car?

ABS, short for Anti-lock Braking System, functions by automatically controlling the braking force during vehicle deceleration to prevent wheel lock-up. It maintains the wheels in a state of rolling and sliding (with a slip ratio around 20%) to ensure maximum traction between the tires and the road surface. The ABS sensor is located on the inner side of the car tire and can be seen when the vehicle is lifted. The ABS system primarily consists of four components: wheel speed sensor, electronic control unit (ECU), hydraulic unit, and ABS warning light. The wheel speed sensor detects the motion state of the wheels, generating sinusoidal electronic pulse AC signals. These signals are then processed by a modulator, converted into digital signals, and transmitted to the electronic control unit. The electronic central control unit (ECU) receives input signals from the wheel speed sensors, calculates parameters such as wheel speed, vehicle speed, and slip ratio, and determines the wheel condition based on the slip ratio. It then issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure in the brake lines according to the control commands, with the adjustment process including pressure maintenance, pressure increase, and pressure decrease. The ABS warning light alerts the driver to potential system malfunctions. If the ABS warning light illuminates, it is advisable to avoid continued driving. An 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 lose control and skid, preventing the driver from decelerating or adjusting the vehicle's trajectory, which poses significant safety risks.

Does a new car purchased two years ago require an annual inspection?

According to regulations, a new car requires an annual inspection in its second year. Here is more information about annual inspections: 1. The normal annual inspection process involves taking the vehicle to an inspection station for checks (lights, tires, emissions, etc.), and then receiving the inspection sticker after the vehicle passes. 2. However, don't forget the '6-year exemption' policy, which essentially means you can skip the vehicle inspection part and directly apply for the inspection sticker. Additional information: 1. For passenger vehicles used for commercial purposes, inspections are required once a year within the first 5 years, and every 6 months thereafter. 2. For trucks and large or medium-sized non-commercial passenger vehicles, inspections are required once a year within the first 10 years, and every 6 months thereafter.

What Causes Water Leakage Under the Car Chassis?

There are several reasons for water leakage under the car chassis: 1. Air conditioning system drainage: During summer, drainage from the air conditioning system is normal. Due to the high temperature inside the car, the cooling system needs to be activated to lower the interior temperature. At this time, moisture from the hot air inside the car condenses on the surface of the evaporator's heat-absorbing fins, which are very cold. The water droplets are collected by the evaporator's plastic housing and drained out of the car through pipes. 2. Water dripping from the muffler and exhaust pipe at the rear of the car: Gasoline is injected into the cylinders and mixed with air. After complete combustion in the combustion chamber, it mainly produces carbon dioxide and water. At high temperatures, water is discharged into the atmosphere in the form of water vapor. Since the muffler is located at the rear of the car where the temperature is relatively low, the water vapor condenses into liquid water. Some of this liquid water is expelled from the exhaust pipe due to the high-speed operation of the engine and the airflow. 3. Lubricant oil leakage: If you notice oil stains on the ground a few hours after parking and restarting the car, it is likely due to engine oil or gear oil leakage. There are many reasons for such leaks, such as broken parts, aging oil pipes, or loose screws. Once oil leakage occurs, it means increased wear on mechanical components. Therefore, it is essential to top up the oil promptly and visit a repair shop to check the issue.

What are the differences between manual transmission and automatic transmission?

The differences between manual transmission and automatic transmission are mainly reflected in four aspects: price, ease of operation, safety performance, and fuel consumption: 1. In terms of price, automatic transmission cars are relatively more expensive for the same class of vehicle. 2. In terms of operation difficulty, the biggest advantage of automatic transmission models is that they are easier to control. Automatic transmissions do not require gear shifting as the system shifts gears automatically, whereas manual transmissions require the driver to shift gears manually. 3. In terms of safety performance, manual transmission models are safer. In emergency situations, manual transmissions can be braked urgently using the foot brake, while automatic transmissions will continue to move a certain distance after the system brakes. 4. In terms of fuel consumption, manual transmission models tend to consume more fuel during normal driving.

What is a car's head-up display?

HUD stands for Head-Up Display, which translates to a head-up display in Chinese. It uses augmented reality technology to project vehicle or road condition information onto the display (primarily the windshield). Different types of HUDs project varying data information such as speed, time, and engine status. Most HUDs use innovative phosphors to project information onto the windshield via lasers. Some HUDs also integrate transparent screens to display critical information. After installing an HUD head-up display in a car, it ensures the driver's safe and stable driving, allowing more focus on observing the road and driving, thereby improving driving safety for each trip. Head-up displays can be categorized into suspended and dashboard types. Suspended HUDs are fixed on the sun visor above the driver, which results in the HUD information being projected onto the upper area of the windshield. Dashboard-type HUDs are fixed on the center console in front of the driver, which determines that the HUD information will be projected onto the front area of the windshield. Cars equipped with head-up displays include: BMW 5 Series Li, Peugeot 3008, Peugeot 508, Audi A6, Audi A7, Lexus GS, and Land Rover Vision concept car, among others.

How to Deal with Car Paint Bubbling?

If the bubbling area of the car paint is small, you can choose to touch it up with the same color paint. If bubbling occurs in multiple parts of the car body, the best solution is to repaint the entire car; otherwise, it will significantly affect the car's appearance. Here are some related car paint maintenance tips: 1. Wash your car regularly. Relying on rain to clean your car is a misconception, as the impact of rainwater on the paint accumulates over time. Initially, it may seem harmless, but prolonged exposure will accelerate paint damage. The correct approach is to rinse your car after rain and wipe it dry. 2. Waxing, glazing, and paint coating can effectively protect the car paint. 3. If substances like asphalt, bird droppings, or chewing gum stick to the paint, clean them off promptly to prevent further corrosion.
