The main components of an airbag are: collision sensor, control module, gas generator, and the airbag itself. The function of an airbag is to reduce the severity of injuries to occupants. Its protection principle is: 1. When a vehicle experiences a certain level of collision force, the airbag system triggers a chemical reaction similar to a small explosive detonation; 2. The airbag, hidden within the vehicle, inflates and deploys instantly, positioning itself in time before the occupant's body collides with interior components; 3. When the body comes into contact with the airbag, the airbag begins to deflate through the pores on its surface, thereby cushioning the impact and reducing the force exerted on the body.

The main components of an airbag remind me of a conversation I had with a friend at an auto show last time. It includes several key parts: first, the airbag itself, usually made of durable nylon material, which can inflate instantly during a collision; second, the sensor system, responsible for detecting impact intensity, such as changes in vehicle speed and acceleration; then there's the inflator, which rapidly releases gas to inflate the airbag; also, the electronic control unit, abbreviated as ECU, which processes signals like a brain; and finally, the wiring harness, which connects all the components together. These parts work closely together to react within milliseconds, protecting passengers from hitting the steering wheel or windshield. During routine maintenance, it's recommended to regularly check the system for any warning lights and avoid aftermarket modifications that could interfere with the sensors.

What are the pros and cons of the auto hold function?

Here is a detailed introduction to the advantages and disadvantages of the auto hold function: 1. Advantages of auto hold: (1) Prevents rolling: In situations such as encountering a red light where a short stop is required, the system will automatically brake the wheels after the vehicle comes to a complete stop to prevent rolling. When starting on an uphill slope, the system will automatically brake to prevent rolling backward, and it will release the wheels to move forward directly after starting. (2) Automatic locking: There's no need to pull the handbrake when parking and locking; the system will automatically brake the wheels, but this feature is only available in some models. 2. Disadvantages of auto hold: (1) Unable to lift the brake: If the auto hold function remains enabled during reversing, you cannot control the vehicle's slow movement by lifting the brake. Poor throttle control may lead to accidents. (2) Jerky feeling: Early versions of the auto hold function may produce a noticeable jerky feeling during use, resulting in a poor experience.

What Causes the Brake Pedal to Be Hard to Press?

The reason the brake pedal is hard to press is due to a leak or failure in the car's vacuum booster pump. The force applied to the brake pedal is amplified by the brake booster pump. If it malfunctions, the brake loses its main assist, making it difficult to press. Solutions for brake failure are as follows: 1. Press the brake pedal multiple times to increase the chance of restoring braking force: If the brakes unexpectedly fail, repeatedly pressing the pedal several times can apply pressure to the brake system, which may have air in the lines, potentially restoring braking force. 2. Turn on hazard lights to alert surrounding vehicles: In a critical situation where the brakes fail, while slowing down, activate the hazard lights and honk to warn nearby vehicles, then call for emergency assistance. 3. Use the handbrake: If it's a mechanical handbrake, pull it up gradually to increase braking force. A sudden, strong pull can lock the rear wheels, leading to dangerous skidding. For electronic handbrakes, operate with extra care while maintaining control of the steering wheel. Simultaneously, downshift to use engine braking to reduce speed. 4. Friction deceleration: Look for objects on either side that can be used for controlled collisions. Avoid direct impact—hold the steering wheel firmly and use multiple gentle collisions to forcibly reduce speed.

What Causes Abnormal Noise When Braking in Reverse?

The main reasons for abnormal noise when a car is reversing are as follows: 1. Break-in period causes directional wear on brake pads. Since the brake disc itself develops scratches, the contact area with new brake pads is initially small, resulting in weak braking force at first. However, prolonged contact and friction cause the surface imprints to align, ensuring sufficient braking force during braking. Yet, this break-in process also creates directional characteristics in the friction layer of the brake pads. 2. Vibration and squealing due to disrupted torque balance. Due to the principles of physical torque, the friction pressure at the front and rear ends of the brake pads differs. The front-end pressure is generally significantly lower than the rear-end pressure. Therefore, in some "multi-piston" caliper products, the pistons closer to the front end of friction are often smaller, leading to abrupt braking engagement during reverse braking and accompanying squealing noises caused by torque imbalance. 3. Accumulation and re-entrainment of wear debris into the friction surface. During operation, brake pads inevitably produce some wear debris, which consists of particles shedding from the surface of the brake pads. These debris accumulate on one side of the brake pad as the brake disc rotates. Reversing suddenly changes the friction direction, causing the debris to be re-entrained between the brake disc and brake pads.

What Causes Transmission Failure?

Here are the specific causes of transmission failure: 1. Blockage formation: Due to excessively high transmission oil temperature, stubborn dirt and impurities accumulate inside the transmission, forming blockages that hinder the movement of solenoid valves. This prevents proper oil pressure regulation, resulting in transmission jerking. 2. Wear occurrence: Under prolonged high-temperature conditions, the anti-wear and lubricating properties of transmission oil deteriorate, causing wear or severe wear on transmission components such as bearings and gears, or damage to gear sides. 3. Hardening and aging: Excessive transmission temperature leads to the hardening and aging of rubber sealing materials, causing leaks due to poor sealing. This ultimately results in reduced hydraulic pressure and, in severe cases, transmission damage.

Can I Change Driving Schools After Passing the First Subject of the Driving Test?

According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," it is possible to transfer to another driving school, which is the most basic right of a student. However, both driving schools must be under the jurisdiction of the same local vehicle management office and meet the necessary transfer procedures. Additionally, transferring to another driving school requires the following three conditions: Both driving schools must belong to the same vehicle management office. The original driving school must agree to the transfer. The receiving driving school must agree to accept the transfer. You can transfer to another driving school after passing the first subject of the driving test. However, since there is a contractual relationship between the driving school and the student, the student needs to negotiate with the driving school. If the driving school agrees to the transfer and refunds part of the tuition, the student can apply to the local vehicle management office and submit the required documents. In some regions, the student must cancel their previous information before transferring. If a transfer is necessary, the student must cancel the previous application information at the vehicle management office before re-registering. In most cases, the previous registration fee cannot be fully refunded. The following conditions are required to apply for a driver's license: Age requirements: Applicants for small cars, small automatic transmission cars, and light motorcycles must be between 18 and 70 years old. Applicants for low-speed trucks, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, or wheeled self-propelled machinery must be between 18 and 60 years old. Applicants for city buses, medium-sized buses, large trucks, trolleybuses, or trams must be between 21 and 50 years old. Applicants for tractor-trailers must be between 24 and 50 years old. Applicants for large buses must be between 26 and 50 years old. Physical requirements: Height: Applicants for small trucks and small buses must be at least 150 cm tall. Vision: Applicants for all vehicle types except large buses and large trucks must have uncorrected or corrected visual acuity of at least 4.9 on the logarithmic visual acuity chart. Color vision: No red-green color blindness. Hearing: Able to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork. Upper and lower limbs: Normal motor function. Applicants for manual transmission cars must have a lower limb length difference of no more than 5 cm. Applicants for automatic transmission cars must have a sound right lower limb. Trunk and neck: No motor dysfunction. If limb defects cannot be confirmed, a certificate from a public hospital stating no diseases affecting safe driving is required. Applicants aged 60 to 70 must undergo a medical examination at a health bureau-designated medical institution. Prohibited conditions for application: Those with organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, Parkinson's disease, mental illness, dementia, or other nervous system diseases that affect limb movement and hinder safe driving. Those who have not yet quit the addiction to narcotics, psychotropic drugs, or long-term use of dependency-inducing psychotropic drugs.

Can You Sleep Inside a Sedan?

In a well-ventilated area, it is possible to sleep inside a sedan. Here are some precautions to take when sleeping in a sedan: 1. Leave a small gap in both side windows. Make sure to open both windows slightly. 2. Turn off the engine, engage the handbrake, and shift into first gear. Before sleeping, ensure the engine is off and the handbrake is engaged to prevent the car from moving while you're asleep. 3. Park in a safe location, considering potential hazards. Try to park on level ground to ensure the car doesn't move due to any slope. 4. Avoid sleeping in the car for extended periods, as the confined space and reduced oxygen levels can lead to chest tightness, shortness of breath, and dizziness upon waking.
