What Must Work Together with Airbags to Be Effective?

Airbags must be used in conjunction with seat belts to provide effective protection. Without seat belts, airbags cannot function properly. If we consider the combined safety provided by airbags and seat belts as 100%, seat belts contribute 70% of the protection, while airbags account for the remaining 30%. Therefore, airbags and seat belts must work together to maximize their protective effects. The working principle of airbags: 1. When a collision occurs while the car is in motion, the airbag sensor first receives the impact signal. If the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic control unit. 2. Upon receiving the signal, the electronic control unit compares it with its pre-stored data. If the conditions for airbag deployment are met, the drive circuit sends an activation signal to the gas generator in the airbag assembly. 3. After receiving the signal, the gas generator ignites the gas-generating agent, producing a large volume of gas. This gas is filtered and cooled before entering the airbag, causing the airbag to rapidly inflate and break through the padding in an extremely short time. The airbag forms an elastic cushion in front of the driver or passenger, then promptly deflates and contracts, absorbing the impact energy. This effectively protects the head and chest, preventing or reducing the severity of injuries.

What Kind of Driver's License is Required to Operate a Tow Truck?

C-class driver's license or above is required to operate a blue-plate tow truck. The tow truck must meet the following conditions: the total length of the vehicle must be less than 6 meters, the tonnage must not exceed 1.5 tons, and the total mass must be less than 4.5 tons. The full name of the tow truck is road tow truck, also known as a wrecker, road rescue vehicle, or towing vehicle. It has multiple functions such as lifting, pulling, and towing. Tow trucks are mainly used for road breakdown vehicles, urban illegally parked vehicles, and emergency rescue operations. Tow trucks are mainly categorized into: integrated towing and lifting type, separate towing and lifting type, one-tow-one type, flatbed one-tow-two type, multi-functional tow truck, and hydraulic automatic clamping type. A tow truck is a specialized vehicle equipped with road emergency operation equipment. Since breakdowns and accidents are inevitable when vehicles are driven on roads, especially on highways, such incidents often occur. The task of the tow truck is to promptly remove the broken-down or accident vehicle from the scene to ensure smooth traffic flow. Therefore, the road tow truck is also known as a road emergency vehicle. With the increase in high-grade roads and the number of vehicles in use, tow trucks have also developed.

What are the main impacts of icy and snowy roads on safe driving?

Icy and snowy roads primarily affect safe driving by making the road slippery. Below is an introduction to the hazardous conditions and preventive measures for driving on icy and snowy roads: Hazardous conditions of icy and snowy roads: Vehicles driving on such roads have poor braking performance and are prone to directional deviation. In emergency braking situations, the braking distance is significantly extended. On icy and snowy roads, the friction coefficient between car tires and the ground is very low, making it difficult to control the vehicle. Improper operation can cause the vehicle to skid or even spin, threatening the safety of the vehicle and its occupants. Preventive measures for icy and snowy roads: To prevent vehicle skidding, when driving on icy or snowy roads, never steer sharply under any circumstances, avoid suddenly increasing or decreasing engine speed to change speed, do not use brakes when turning or on curves, and always avoid emergency braking. It is essential to refrain from using emergency braking, avoid sudden steering, and control the vehicle speed properly. Generally, driving speed on icy or snowy roads should not exceed 20 kilometers per hour.

What Causes Insufficient Power and Clicking Noises When Driving an Automatic Transmission Car Uphill?

Insufficient power and clicking noises when driving an automatic transmission car uphill are caused by the phenomenon of gear dragging. The reasons include: prolonged vehicle usage, aging shift mechanism, aging synchronizer, and poor driving habits. When driving, it is necessary to select the appropriate gear based on speed and road conditions, and avoid using the same gear continuously. Method for starting an automatic transmission car on an uphill slope: 1. When parked on a slope, before ignition, press the brake and clutch pedals, and make sure to engage the handbrake. 2. Shift into first gear, slowly lift the clutch pedal with your left foot, while quickly moving your right foot to the accelerator pedal. 3. You can gently apply throttle while slowly releasing the clutch. When the engine speed exceeds 2000 RPM, you will feel the front of the car slightly lift, and the body will gently shake, indicating that the clutch has begun to reach the semi-engaged state. At this point, continue to release the clutch and press the accelerator while releasing the handbrake, allowing the car to smoothly ascend the slope. 4. When practicing, always start with gentle slopes and gradually increase the difficulty. In fact, the process of practicing uphill starts is essentially practicing the coordination between the accelerator and clutch.

Why is the USB port in Mercedes-Benz cars a small interface?

This is a design issue, as the small port is more convenient. The USB port is located below the center console panel and is accompanied by a card reader and a 3.5mm headphone jack. The car USB can be used to read USB drive information for the car entertainment system, charge mobile phones, and other functions. However, due to power limitations, the charging rate is not high. When using a USB car charger, pay attention to the following three points: Pay attention to the voltage range: During the charging process of the mobile phone battery, ensure that the output voltage of the power supply is within the specified range; otherwise, the charging function cannot be achieved. Keep the USB car charger dry: Rain, moisture, and various liquids or moisture may contain minerals that can corrode electronic components and circuits. Under normal conditions, this part of the circuit will reduce the output voltage by about 0.6V and decrease stability. However, the negative feedback established through R21 and R32 on the transistor can eliminate these issues. A high-quality reference voltage source is essential: The reference voltage chip IC2 is connected to an emitter follower (T4), so the reference power supply can provide up to several milliamperes of current. Car charger wholesale manufacturers remind everyone not to place the USB car charger in high-temperature areas. High temperatures will shorten the lifespan of electronic devices, damage the battery, and cause some plastics to age.

What is the reasonable speed for driving through a narrow bridge?

When driving through a narrow bridge, the speed should not exceed 30 km/h. Here is a detailed introduction about vehicle speed: 1. Overview: Vehicle speed refers to the distance traveled by a vehicle per unit of time, abbreviated as speed, commonly measured in kilometers per hour or meters per second. 2. Classification: Vehicle speed is one of the three parameters describing traffic flow and plays an important role in traffic flow theory research. Vehicle speed can also generally refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly divided into spot speed, segment speed, and design speed.
