What does ABS mean on a car?

ABS, short for Anti-lock Braking System, functions by automatically controlling the braking force during vehicle braking to prevent wheel lock-up. It keeps the wheels in a state of rolling and sliding (with a slip ratio of around 20%), ensuring maximum adhesion between the tires and the road surface. The ABS sensor is located on the inner side of the car's tires and can be seen when the vehicle is lifted. The ABS system mainly 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 and emits a sinusoidal electronic pulse AC signal. This signal is then processed by a modulator, converted into a digital signal, 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's condition based on the slip ratio. It then sends 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 any system malfunctions. If the ABS warning light is on, it is advised 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, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

How many points are deducted for not using lights correctly when a vehicle breaks down on the road?

Not using lights correctly when a vehicle breaks down on the road will result in a deduction of 3 points. Failure to use warning lights as required: After a vehicle is involved in an accident on the road, if it obstructs traffic and is difficult to move, and the warning lights are not used as required, a fine will be imposed and 3 points will be deducted. Failure to use lights correctly when passing through an intersection: When a motor vehicle passes through an intersection controlled by traffic signals without using the lights as required, a fine will be imposed and 1 point will be deducted. Failure to use lights correctly when changing lanes: When a motor vehicle changes lanes without using the lights as required, resulting in an accident, a fine will be imposed and 1 point will be deducted. Please strictly use lights when changing lanes.

Is There a China 7 Emission Standard?

Currently, there is a China 7 emission standard. Implementation timeline of China 7 emission standard: Based on current policy projections, China 7 may be fully implemented after 2025; at the same time, the implementation period of China 7 could be shorter than that of China 6, mainly because relevant authorities are increasingly stringent in vehicle emission regulations; moreover, the primary regulatory target of the China 7 standard will be trucks. Objectives of China 7 emission standard: The China 7 emission standard is expected to further reduce the maximum allowable emissions of air pollutants compared to the China 6 standard, such as fine particulate matter, hydrocarbons, and carbon monoxide.

What is automotive OTA upgrade?

OTA (English: Over the Air Technology) refers to the over-the-air download technology, which automatically downloads upgrade packages and performs upgrades via the internet. The application of OTA technology enables mobile communication to not only provide voice and data services but also offer new service downloads, making it a faster wireless technology. Methods for vehicle OTA upgrade: 1. Connect the vehicle to the internet and perform an online upgrade. 2. Download offline data packages to carry out the upgrade. 3. Drive the car to a 4S store and have the staff assist with the upgrade.

What is the purpose of the plus and minus buttons on the gear shift?

The plus and minus buttons on the gear shift primarily serve the functions of locking the gear and parking lock. Correct usage of the button on the gear shift: After the car enters the parking position, press the brake to shift the gear lever to N, engage the handbrake, release the foot brake and then turn off the engine, and finally push the gear lever into P. Precautions for the plus and minus buttons: When using the plus and minus buttons, pay attention to whether you are using the gear shift handle or the paddle shifters. The gear shift handle usually requires pushing forward to increase a gear and pulling backward to decrease a gear. If paddle shifters are used, there are usually indicators.

Can a Water-Damaged Car Key Still Be Used?

If your car key gets wet, avoid using it immediately. Wait until it's properly treated before continuing to use it. Here are the treatment methods: 1. Wipe off the water: Do not press any buttons on the car key immediately after it gets wet, as this can cause water to seep into the inner layers faster. First, use a dry cloth or tissue to clean the surface. Then, disassemble the casing, remove the battery, and use highly absorbent tissues to wipe off any internal moisture. 2. Dry with cool air: Next, use a hairdryer on the cool setting to dry it. Never use hot air, as the circuit board inside the key should not be exposed to excessive heat. 3. Place it in a rice container: Alternatively, you can wrap the key in a breathable bag and place it in a dry rice container. Rice is highly absorbent and can help draw out moisture. 4. Clean with alcohol: Purchase high-concentration alcohol from a pharmacy and use a cotton swab dipped in alcohol to gently clean the internal button contact points and other areas. Let it dry afterward, as high-concentration alcohol has strong moisture-absorbing properties. 5. Send it for repair: Car remote keys are generally made of waterproof materials, but there are small gaps between the keys. If the above methods fail to salvage the water-damaged key, the only option is to send it to a repair shop or 4S store for replacement or repair.
