What does VDC in a car mean?

It refers to the Vehicle Dynamics Control (VDC) system. The English name is Vehicle Dynamics Control, abbreviated as VDC, and the Chinese name is the vehicle dynamic control system. When the car experiences wheel slippage, rollover, or loss of tire traction, the VDC system immediately intervenes by reducing engine speed and selectively applying braking to individual wheels, ultimately guiding the car back to its normal driving path to prevent hazards caused by loss of control. Differences between VDC, ABS, EBD, and TCS: TCS function: When the drive wheels slip, the TCS control system reduces engine torque through the ABS/VDC control system. If necessary, it communicates with the automatic transmission control module to adjust shift timing, reducing wheel slippage, improving vehicle acceleration performance, eliminating wheel steering failure, and enhancing driving stability. ABS function: The Anti-lock Braking System (ABS) detects wheel speed during braking and sends the signal to the ABS control unit, which controls braking force (brake fluid pressure) via solenoid valves to prevent wheel lock-up. It enhances operational stability during emergency braking and makes steering to avoid obstacles easier. EBD function: During braking, EBD detects minor slippage in the front and rear wheels. If slippage occurs, EBD controls the rear wheel braking force (brake fluid pressure) to minimize rear wheel slippage and improve braking stability. VDC system, as a supplement to TCS/ABS functions, detects steering input and braking operation via the steering angle sensor and brake switch. Using sensors like the vehicle speed sensor, it determines the vehicle's driving state (understeer/oversteer). When the vehicle makes sharp turns or drives on slippery roads, the VDC system adjusts engine torque or applies independent braking to each wheel to maintain driving stability. In advanced automotive industries, the ABS/ASR system has evolved into the Vehicle Dynamics Control (VDC) system. This system integrates the control functions of braking, driving, suspension, steering, and engine into a cohesive unit. It ensures excellent directional stability and optimal driving performance under various harsh conditions, such as icy roads, uneven surfaces, curved roads, evasive maneuvers, braking, acceleration, and downhill driving, regardless of load, tire pressure, or tire wear. VDC represents a new milestone in active vehicle safety by reducing driver demands in braking, acceleration, and steering. Other in-car button functions include: Fuel tank release button: This button remotely opens the fuel tank cap. Vehicles equipped with this feature allow the driver to open the fuel tank cap from inside the car. ESP switch: This turns the vehicle's ESP system on or off. The ESP system is active by default. Reverse radar button: This allows the driver to manually enable or disable the reverse radar system as needed.

Why is the handbrake not working?

The handbrake is not working because the brake pads of the handbrake are severely worn. Related introduction: 1. Introduction: The professional term for the handbrake is auxiliary brake, which differs in principle from the main brake. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Long-term use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel will also increase. 2. Expansion: The handbrake is used in conjunction with a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With long-term use, the spring will also undergo corresponding deformation.

Can the driving trajectory of a car be checked?

You can check the driving trajectory of a car at the traffic management department. For your own vehicle's driving trajectory, it can only be queried if you have previously recorded and uploaded it to the internet. Driving trajectory query is a blocking system based on an intelligent traffic management system, equivalent to what people commonly call the "eye system." Through this system, by simply entering the car's license plate number, you can query the vehicle's driving trajectory and also check the times the car appeared under various surveillance cameras. After querying the positions of the surveillance probes, the car's driving trajectory is formed, meaning every movement of the car can be monitored. This system significantly improves the office efficiency of traffic management departments. However, this system can only be used by traffic management departments, making it difficult to easily check a car's driving trajectory. Things to note about driving trajectories: GPS does not have the function to query the driving trajectory of others or your own vehicle online or in reality: For your own vehicle's driving trajectory, it can only be queried if you have previously recorded and uploaded it to the internet. If it has not been recorded or uploaded, there is no possibility of querying your vehicle's trajectory. The GPS positioning system and vehicle tracking device are integrated, meaning you must install a tracking device to use this positioning system. Then, within the positioning system, you can query the vehicle's location, along with some mileage statistics and trajectory playback. Generally, it is not easy to check a vehicle's driving trajectory. With satellite positioning, relevant authorities can set up monitoring trajectories to check the driving trajectory.

What does vehicle registration location refer to?

Vehicle registration location refers to the jurisdiction where the vehicle is registered, primarily determined by the location of the vehicle management office where the registration is processed. The location of the vehicle management office indicated by the registration seal at the bottom left of the main page of the motor vehicle license is the vehicle's registered location. The vehicle license consists of three parts: the license holder, the main page, and the supplementary page. Among them: the front side of the main page contains the endorsed core document, the back side displays the vehicle's photograph, and it is sealed with a plastic cover. The supplementary page is the endorsed core document. Materials required for registration application: (1) Identity proof of the vehicle owner. (2) Proof of vehicle origin, such as the purchase invoice. (3) Proof of vehicle compliance with national standards for whole vehicle factory production or import documentation for imported vehicles. (4) Proof of payment of vehicle purchase tax or tax exemption certificate. (5) Proof of compulsory motor vehicle traffic accident liability insurance. (6) Proof of payment or tax exemption for vehicle and vessel tax. (7) Other proofs and certificates required by laws and administrative regulations to be submitted during vehicle registration.

Is there a charge for checking tire pressure warning at a 4S shop?

Tire pressure warning checks at a 4S shop are generally free. Related information: 1. Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. There is a standard tire pressure indicator printed on the rear end of the driver's side door, which is the pressure when the tire is cold, i.e., when the car has been parked for at least three hours or driven no more than 1.6km. The tire pressure is most accurate when measured with the tire cold. 2. Expansion: Air pressure is the lifeblood of the tire. Both too high and too low pressure will shorten the tire's service life. Low pressure will increase the deformation of the tire body, easily causing cracks on the tire side, and also generate flexing motion, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, and breaking of the cords. It will also increase the tire's contact area with the ground, accelerating wear on the tire shoulders.
