The reasons for brake noise in new cars are as follows: 1. Metal hard spots on brake pads: If there are tiny metal particles on the brake pads, they will produce a screeching sound when braking. You can try slamming the brakes a few times or grinding/replacing the brake pads. 2. Severely worn brake discs: After prolonged use, deep grooves may form on the brake discs at the friction points with the brake pads, causing noise during braking. If the grooves are shallow, grinding the edges of the brake pads may solve the issue. If the grooves are deep, replacing the brake discs is the only option.

What to Do If the Vehicle Annual Inspection Label Is Lost?

If the vehicle annual inspection label is lost, it should be promptly replaced. You need to bring the vehicle registration certificate and the owner's ID card to the local vehicle management office in the city where the vehicle is registered to fill out a replacement application form. After approval, a new annual inspection label will be reprinted. Different regions may have different replacement procedures, so owners should consult the relevant authorities to avoid unnecessary losses. Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual check-up for the vehicle based on the safety technical conditions for motor vehicle operation. Vehicle annual inspections help promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.

What does TCU mean in cars?

The TCU in cars is the Transmission Control Unit, commonly used in automatic transmissions such as AMT, AT, DCT, and CVT, to achieve automatic gear shifting control, making driving simpler. Its main functions include: 1. Target gear decision: Based on driving environment and driver-recognized strategies, it improves vehicle economy and comfort; 2. Actuator control; 3. Fault diagnosis and fault handling. The TCU can detect certain data, such as engine speed and vehicle speed, and use this data to control the transmission for gear shifting. The shifting logic is calibrated by the car manufacturer's engineers through test driving experiments, data collection, user operating conditions, and targeted consumer groups. Good shifting logic can understand the driver's intentions.

What does SOC in cars represent?

Automotive SOC refers to the State of Charge. Many hybrid vehicles have this indicator light, while pure gasoline vehicles do not. Common hybrid vehicles include conventional hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs). Plug-in hybrid vehicles can use external power sources to charge their traction batteries, which distinguishes them from conventional hybrid vehicles. The advantages of plug-in hybrid vehicles include better fuel economy compared to pure gasoline vehicles and longer driving range than pure electric vehicles, qualifying them for green license plates. Conventional hybrid vehicles have similar fuel economy to plug-in hybrids, but their electric-only driving range is shorter than that of plug-in hybrid vehicles.

Under what circumstances are clearance lights generally turned on?

Clearance lights are generally turned on under the following circumstances: 1. When driving in foggy weather, as visibility decreases and vision becomes blurred, clearance lights should be turned on along with fog lights to provide a good warning effect for other traffic participants on the road; 2. During rainy weather, they serve as a warning for both preceding and following vehicles to minimize potential harm; 3. Nighttime driving requires the use of clearance lights as per traffic regulations, which mandate the activation of rear tail lights and clearance lights to alert following vehicles; 4. When driving at dusk, visibility is challenging due to the absence of streetlights and insufficient brightness of vehicle lights, hence turning on clearance lights enhances visibility for other vehicles and ensures safety.
