What does EBD mean in a car?

EBD in a car refers to Electronic Brakeforce Distribution. EBD is actually an auxiliary function of ABS, which adds a control software to the ABS control computer, while the mechanical system remains completely consistent with ABS. It serves as an effective supplement to the ABS system and is generally used in combination with ABS to enhance its effectiveness. During emergency braking, before ABS activates, EBD automatically compares the slip rate of the rear wheels to that of the front wheels based on the vehicle's weight and road conditions. If it detects that this difference needs adjustment, the brake hydraulic system will adjust the pressure transmitted to the rear wheels to achieve a more balanced and closer-to-ideal distribution of braking force. Vehicles equipped with the EBD system can automatically detect the adhesion conditions between each wheel and the road surface, appropriately distributing the force generated by the braking system to all four wheels. With the assistance of the EBD system, braking force can achieve optimal efficiency, significantly reducing braking distance while maintaining vehicle stability during braking, thereby improving driving safety.

What does the (!) symbol on the car dashboard mean?

Car dashboard (!) represents the brake system warning light. The brake system warning light indicates: 1. Some vehicles illuminate this light for a few seconds when the ignition is turned on, then it turns off after starting the engine; 2. Low brake fluid level or deteriorated brake fluid, which may illuminate during driving; 3. Malfunction in the brake system; 4. ABS failure may also trigger this light; 5. Severely worn or failed brake pads can cause this warning light to illuminate. This warning light is easily confused with the parking brake indicator. The parking brake light appears when the handbrake is engaged while driving, symbolized by a 'P' in the middle, whereas the brake system warning light features an exclamation mark and indicates issues with the braking system. When the brake system warning light appears, it's necessary to check for brake pad wear, brake failure, deteriorated or low brake fluid level, ABS failure, and other related issues.

Is It Normal for Brake Discs to Rust?

It is normal for brake discs to rust as they are made of cast iron. When the vehicle remains stationary for extended periods or in high humidity conditions, rust may appear. Driving the car and applying the brakes several times can wear off the rust on the brake discs. Solution for slight rust: Minor rust on brake discs can be removed through normal braking. The principle involves the friction between the brake pads and the brake discs to achieve a rust removal effect. After applying the brakes several times, the brake discs will shine like new. Solution for severe rust: When brake discs are severely rusted, normal braking may not effectively remove the rust. Severe rust on brake discs can cause uneven surfaces, leading to issues such as steering wheel vibration and abnormal brake noises when braking. In such cases, it is best to take the car to a 4S shop, remove the brake discs, sand off the rust with sandpaper, ensure the brake pads are in good condition, reinstall them properly, and conduct a road test. If there is no significant vibration, the vehicle can be used normally.

What does ACC mean in cars?

ACC in cars stands for Adaptive Cruise Control. The Adaptive Cruise Control system is an intelligent automatic control system that has evolved from the existing cruise control technology. The adaptive cruise system uses low-power radar or infrared beams to determine the exact position of the vehicle ahead. If it detects that the vehicle ahead is slowing down or a new target is detected, the system sends a signal to the engine or braking system to reduce the vehicle's speed, maintaining a safe distance from the vehicle ahead. When controlling the vehicle's braking, the Adaptive Cruise Control system typically limits the deceleration to a level that does not affect comfort. If greater deceleration is needed, the ACC control unit will issue audible and visual signals to prompt the driver to take active braking measures. When the distance to the vehicle ahead increases to a safe distance, the ACC control unit will adjust the vehicle's speed to the preset cruising speed.

What does a keyless entry system mean?

Keyless entry system means starting the vehicle without taking out or turning a physical key. Simply keep the key in your bag or pocket, then press the in-car button or turn the knob to ignite the engine. One-button start is a derivative function of the keyless entry system. The keyless entry system refers to an intelligent system that utilizes advanced RFID (Radio Frequency Identification) technology and identity code recognition. With this system, the owner no longer needs to use a traditional mechanical key to unlock the car door or start the vehicle. Instead, they only need a key equipped with a smart chip to sense the vehicle. When the owner steps within a specified range, the system can identify them as the authorized driver and automatically unlock the door.

Is the AC light on for cold air or hot air?

The AC light on indicates cold air, because when the AC function is activated, the air conditioning compressor starts working. AC is short for Air Condition, which translates to air control and air conditioning in Chinese. In a car, it can be understood as the air conditioning cooling switch. When the AC light is on, the air conditioning compressor starts, increasing the engine load and consequently fuel consumption. Besides cooling, the air conditioning compressor also serves to dehumidify. Turning on the AC button helps maintain a dry interior, preventing fogging on the car windows and keeping the temperature inside the car constant.
