Is Full-Speed Adaptive Cruise Control Autonomous Driving?

Full-speed adaptive cruise control is not autonomous driving. It is a system where the vehicle automatically detects vehicles ahead on the road and controls the speed to maintain a safe distance from the preceding vehicle, while steering still requires manual control. It allows the vehicle's cruise control system to adjust speed according to traffic conditions, unlike traditional cruise control which only maintains a constant vehicle speed. During driving, the distance sensor installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects speed signals. Full-speed adaptive cruise control can free the driver's feet, better alleviate driving pressure, and to some extent improve the vehicle's fuel economy.

As a frequent commuting driver, I often use full-speed adaptive cruise control on highways to pass the time. It automatically adjusts speed to maintain distance and can even start from zero to handle traffic jams, making my hands much more relaxed and reducing fatigue by half. However, it is definitely not autonomous driving—I still need to keep a close eye on the road while using it, as it doesn't handle steering or sudden situations like a bicycle suddenly crossing. If I'm not careful, the risk of accidents increases significantly. Compared to true autonomous systems like Tesla's FSD, ACC is much simpler, only managing acceleration and deceleration without lane-changing or traffic light recognition. I recommend everyone read the manual before trying it, understand its limitations, and not rely too much on it. Safety and regulations should always be the core of driving.

I've been driving for twenty years, witnessing the evolution of automotive technology from mechanical to electronic systems. The full-speed adaptive cruise control is truly a hassle-free assistant—it can follow the car ahead by decelerating and accelerating automatically, making it ideal for long-distance trips. However, it's still just a driving aid and doesn't reach the level of autonomous driving. For instance, it fails in curves or complex intersections, requiring manual takeover. I've compared ACC with traditional cruise control; ACC adds automatic braking functionality, but its core still relies on radar sensing. If the sensors get dirty or the signal is interrupted, it becomes ineffective. Drivers must remain fully attentive at all times and avoid distractions like using mobile phones, as safety comes first. Such assistance systems are convenient for daily use, but don't expect them to handle all road challenges automatically.

How long after the vehicle inspection can it be checked on 12123?

It can be checked on 12123 72 hours after the vehicle inspection. Introduction to vehicle inspection: The traffic police department conducts an annual inspection of the vehicle's condition and performance, also known as the annual inspection. New vehicles are inspected every two years. Contents of the vehicle inspection: Check whether the engine, chassis, body, and auxiliary equipment are clean, complete, and effective, whether the paint surface is uniform and aesthetically pleasing, and whether the main assemblies have been replaced. Verify whether it matches the initial inspection record; Check whether the vehicle's braking performance, steering control, lighting, exhaust, and other safety performance meet the technical requirements for safe operation of motor vehicles; Check whether the vehicle has been modified, remodeled, or transformed, whether the driving license, license plate, and vehicle file records match the current vehicle condition, whether there are any changes, whether approval and modification procedures have been completed, and whether the license plate, driving license, and enlarged license plate markings on the vehicle are damaged, altered, or unclear, and whether they need to be replaced.

What is the HOLD light?

HOLD light is the gear lock indicator light. When the HOLD light is on, it indicates that the gear is locked in a specific position. When driving uphill or on icy/snowy roads that require low-gear operation, you can activate HOLD to lock the transmission in second gear. The button for this switch is located in the middle of the gear lever. Pressing it again will deactivate the function. Normally, it's not recommended to use this feature as it may harm the transmission. Automatic gear lock is a forced downshift key, used when gears get stuck or during towing. When HOLD is activated, the parking brake system will automatically engage each time the vehicle comes to a complete stop after braking. You'll feel a release of pressure on the brake pedal, at which point you can release the pedal without worrying about the vehicle rolling. Working principle of gear lock indicator light: The transmission control unit uses this sensor to detect the gear selected by the driver and performs corresponding control actions. Relationship between neutral switch and gear position switch: In older vehicles, the P (Park) and N (Neutral) switches were connected in series with the starter motor switch, meaning the engine could only be started in these two positions. In newer vehicles, the control unit identifies the neutral signal first, then decides whether to engage the starter motor.

What Causes Engine Shaking When Warm?

Here are the specific reasons for engine shaking during warm idle: 1. Fuel system issues: Typically caused by fuel line blockages leading to poor fuel supply, manifested as engine shaking, unstable idle, or stalling while driving. Fuel pump failure can also cause engine shaking. To diagnose fuel pump problems, disconnect the fuel line and check fuel flow rate and volume. 2. Electrical system issues: Check whether spark plugs are worn, if gaps are uniform, or if gaps have changed. Additionally, malfunctioning distributors can cause engine shaking. 3. Mechanical reasons: Inspect engine operation for abnormal sounds or valve noise. Check belt condition for looseness.

What Causes Difficulty in Removing the Car Key?

Car key difficulty in removal can be attributed to the following reasons: 1. P gear not properly engaged: When exiting the vehicle, the gear was not shifted to P or the P gear did not fully engage, possibly obstructed by an object, thus failing to trigger the electronic sensor. 2. Steering wheel locked: The steering wheel was not returned to its proper position when parking, causing an abnormal lock. The solution is to insert the key, attempt to turn the steering wheel left and right while twisting the key, which will release the steering wheel lock. 3. Obstruction in the key slot: The solution involves removing the obstruction, starting the car, shifting the gear again to ensure it is fully engaged, after which the key can be removed.
