What is the Difference Between Cruise Control and Adaptive Cruise Control?

The differences between cruise control and adaptive cruise control lie in their applicable road conditions, functions, principles, nature, and characteristics. The specific details are as follows: Applicable Road Conditions: Cruise control is suitable for good road conditions, such as highways and roads with light traffic; adaptive cruise control is suitable for highway conditions and can also be used in urban road conditions. Function Differences: In emergency situations, cruise control relies solely on the driver's manual operation; adaptive cruise control can maintain the vehicle's longitudinal movement and, in the event of a collision risk, will alert the driver and actively intervene with braking. Vehicles are equipped with cruise speed control buttons, visible on the steering wheel, allowing the driver to control the distance from the vehicle ahead. If the driver needs to rest, they should place their foot on the edge to the right of the accelerator pedal, making it difficult to accidentally press the accelerator and achieve sudden acceleration, thus enhancing safety. Differences in Principle, Nature, and Characteristics: Once the speed is set, the cruise control system maintains that speed. However, this poses a significant safety hazard, as cruise control will continue at the set speed regardless of the situation and will not automatically slow down in emergencies. In contrast, the adaptive cruise control system can set a safe distance and will adaptively reduce the vehicle's speed when a potential hazard is detected, eliminating safety risks. Overall, the adaptive cruise control system is more intelligent, safer, and more user-friendly. Cruise control, abbreviated as CCS, can be equipped in both manual and automatic transmission vehicles. It allows the vehicle to travel at the speed set by the driver, eliminating the need to press the accelerator pedal. Adaptive cruise control is more intelligent, enabling the vehicle to judge braking and adjust speed based on road conditions. Cruise control is generally usable at speeds between 30 km/h and 150 km/h, depending on the vehicle model, but this feature is not suitable or safe in current road traffic conditions. Adaptive cruise control (ACC) is only available in automatic transmission vehicles because it does not maintain a constant speed; the speed changes dynamically, requiring an automatic transmission to accommodate this feature. Adaptive cruise control is divided into: standard adaptive cruise control (simple speed control) and full-speed range adaptive cruise control (intelligent driving). Adaptive cruise control is semi-autonomous driving, where the vehicle's speed is set to a fixed value. When there is a vehicle ahead, the speed will appropriately decrease, and when overtaking, the vehicle will accelerate back to the preset speed. It can also include a follow-up system (this feature is based on full-speed range adaptive cruise control and requires vehicles with L2-level autonomous driving capabilities). Adaptive cruise control is more advanced than cruise control, incorporating a digital information processor, radar sensor, and control module, making it more intelligent.

Should You Use Internal or External Air Circulation When Turning on the Heater in Winter?

When using the heater in winter, it is recommended to use internal circulation for short trips and external circulation for long trips. Below are detailed explanations of internal and external circulation: 1. Internal circulation system: The air exchange channel between the inside and outside of the car is closed. When the fan is off, the airflow inside the car does not circulate. When the fan is on, the incoming airflow is only drawn from inside the car, creating an internal airflow cycle. 2. External circulation system: External circulation mode uses the fan to draw air from outside the car into the cabin. The air blown by the fan comes from outside the car. Even if the fan is off, airflow is still drawn into the car while driving, replenishing fresh air inside the cabin.

Will I Be Fined for Not Carrying My Driver's License?

Driving without carrying a driver's license will result in a fine ranging from 20 to 200 yuan and a deduction of 1 point. Below is the relevant information: 1. Driver's License: Refers to the legal document issued by the administrative authorities after a person who is legally permitted to learn to drive a motor vehicle has studied and mastered traffic regulations and driving skills, and passed the relevant examinations, granting permission to drive a certain type of motor vehicle. 2. Purpose of Traffic Police Inspection: (1) Inspection of the Driver's License: To check whether it was legally obtained, whether it is still valid, whether the information on the license is forged, and whether the vehicle type being driven is within the permitted driving categories, etc. (2) Inspection of the Vehicle License: To check whether it was legally obtained, whether it is still valid, whether the information on the license is forged, and whether there are modifications that have not been registered, etc.

Can Old Tires Be Sold for Money?

Old tires that have been replaced can be sold for money, but the price is relatively low. When selling, the tire tread and any issues such as scars or bulges will be considered. If there is damage, the tires won't be worth much because the structure of a car's tire sidewall differs from that of the tread. Small cracks can increase the probability of tire blowouts. Below is an introduction to the functions of car tires: 1. Supporting weight: They bear the entire weight of the vehicle, handle the car's load, and transmit forces and moments in other directions. 2. Cushioning impact: They transmit traction and braking torque, ensuring good adhesion between the wheels and the road to improve the car's power, braking, and passability. Together with the car's suspension, they cushion impacts during driving and dampen resulting vibrations. 3. Ensuring safety: They prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel economy.

What Causes a Driver's License Downgrade?

Reasons for driver's license downgrade: Accumulating 12 or more penalty points within one scoring cycle. Being involved in a major accident resulting in death and bearing 50% or more responsibility. Having penalty points in three consecutive scoring cycles without undergoing the required review. Automatic downgrade to C1 license when reaching 60 years of age. A driver's license, also known as a "driving license," is an official document issued by government transportation authorities to individuals qualified to drive, typically in card form. To obtain a driver's license, one must meet the minimum age requirement and pass a driving test. The license usually specifies the types of motor vehicles the holder is permitted to drive, such as motorcycles, passenger cars, trucks, buses, etc. For holders of licenses for large buses, tractors, urban buses, medium-sized buses, or large trucks who meet any of the above conditions, the vehicle management office shall revoke their highest permitted driving category and notify them to complete downgrade procedures within 30 days. After completing downgrade procedures, if the driver wishes to reapply for the revoked driving category, they must have no record of accumulating 12 penalty points in the current scoring cycle and the most recent one prior to application, and must not have been involved in any fatal accident where they bore equal or greater responsibility. Procedures for downgrading after revocation of highest permitted driving category: After passing relevant examinations, receive the "Motor Vehicle Driver's Illegal Full-Point Examination Information Feedback Notice" (for A and B class licenses, downgrade information will be noted on the notice). After the suspension period ends, present ID card and the notice to retrieve the license from the traffic police department where it was confiscated. Submit the following documents to the issuing vehicle management office for downgrade procedures (to be completed within one working day if no outstanding traffic violations exist): Original "Motor Vehicle Driver's License Application Form." Original and copy of the driver's identity proof. Original driver's license. Three recent front-facing, bareheaded, white-background color ID photos (submit digital photo collection receipt if required locally).
