What is ABS in a car?

ABS, short for Anti-lock Braking System, functions to automatically control the braking force during vehicle deceleration, preventing the wheels from locking up and maintaining a rolling-sliding state (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 sensors, electronic control unit (ECU), hydraulic unit, and ABS warning light. The wheel speed sensors detect 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, determines the wheel condition based on the slip ratio, and 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 holding, 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 not to continue 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 skid uncontrollably, preventing the driver from decelerating or adjusting the vehicle's trajectory, posing significant safety risks.

Why is there no car purchase contract?

A car purchase contract is merely an agreement of sale. The contract signed during the car purchase primarily stipulates the model, color, configuration, price, etc., of the vehicle being purchased. Once the buyer takes delivery of the car, this contract generally loses its value. Therefore, some 4S dealerships may skip issuing the contract altogether or reclaim it after the transaction is completed to save effort. More information about car purchase contracts is as follows: Introduction: A car purchase contract is a formal sales agreement signed between the buyer and the dealer, serving as a basis to protect the rights and interests of both parties. Signing: During the transaction of a used vehicle, it is mandatory to sign a car purchase contract supervised by the industrial and commercial authorities, also known as the sales contract. The contract is issued in duplicate, with each party holding one copy.

What does AC mean in car air conditioning?

AC button is the cooling switch for car air conditioning, meaning that the air conditioning compressor will only operate when this button is pressed, and the air blown out by the blower will be cold air. The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle compartment. Relevant information about car air conditioning is as follows: Introduction: The car air conditioning device (air-conditioning-device) is referred to as car air conditioning for short. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the vehicle compartment to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it also creates good working conditions for the driver and serves as an important ventilation device for ensuring safe driving.

What Are the Various Warning Indicators on the Dashboard?

Introduction to car dashboard warning indicators is as follows: Engine Self-Check Indicator: A yellow icon on the dashboard, this is the engine self-check indicator used to display the working status of the engine. When you turn the key and the vehicle performs a self-check, this indicator will light up. It will automatically turn off after the car is started. Fuel Indicator: This reminds the owner that the fuel is low. When the fuel indicator lights up, the car can generally run for another 30-60 kilometers. Operating with extremely low fuel levels may increase engine wear due to poor lubrication or overheating. Tire Pressure Warning Light: If this light comes on, you must immediately get out and check if there is an issue with the tires. While driving on the highway, you must pull over to the side and place a hazard sign 100 meters ahead. Proper tire pressure affects driving speed. Coolant Temperature Indicator: This indicator warns of excessively high engine coolant temperature. Normally, the pointer stays in the middle range and the light is off. If the light comes on, it means the coolant temperature is too high, and you should turn off the engine and wait for the temperature to drop before continuing to drive.

What to Do If You Exceed the First Maintenance Mileage?

If the car owner exceeds the specified mileage, it is best to immediately call the 4S shop and explain the reason. Usually, the 4S shop will not be too strict to trouble the consumer. Generally speaking, the first maintenance for a new car is based on the mileage and the specified first maintenance time, whichever comes first. If the mileage exceeds a little, there will be no problem. If it exceeds the specified time too much, a fee will be charged. Before doing the first maintenance, pay attention to the following points: Make an appointment in advance: First, it is best to make an appointment with the 4S shop in advance. Otherwise, if you go without an appointment, you may encounter situations where there are no workshops available or you have to wait in line for a long time.

Relevant information about the wiper is as follows: Introduction: The wiper, also known as a windscreen wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Usage: On rainy days, when raindrops fall on the windshield, the view ahead quickly becomes obstructed, making vehicles, pedestrians, and scenery appear blurry. At this point, turning on the wiper will restore a clear view ahead.
