Solutions to three major emergency safety issues during high-speed driving

Three major emergency safety issues during high-speed driving and their solutions

Common Faults
1. Brake failure during high-speed driving
This issue ranks first among all the problems that the surveyed car owners are most concerned about regarding potential malfunctions. In fact, the failure of the brakes is a very rare occurrence during normal driving. However, if it does occur and is not handled properly, the consequences can be extremely serious. Therefore, car owners need to acquire the necessary knowledge about emergency braking in advance. The main causes of brake failure are:
The necessary maintenance of the braking system was lacking, such as excessive impurities in the brake master cylinder due to long-term driving, poor sealing, failure of the vacuum booster pump, dirty brake fluid, or the use of several types of brake fluid mixed causing air blockage when heated, leakage of the brake master cylinder or booster pump, leakage at the air reservoir or pipeline interfaces.

2. The malfunction of the machine components occurred due to improper operation. For instance, the brake pads were severely worn out and thus failed, the brake hub was carbonized, and the braking function was lost.

3. Due to severe overloading, under the influence of gravitational acceleration, the inertia of the vehicle during high-speed movement increased, which directly led to the failure of the brakes.

Solution:
Handbrake braking
After the brakes fail, one should remain calm. First, use the handbrake to gradually slow down the vehicle. When pulling the handbrake, press your fingers into the safety button on the handbrake to make the continuous pulling and releasing smoother, allowing the vehicle to slow down and stop. Do not pull the handbrake forcefully out of panic; otherwise, excessive force may cause the steel wire rope to break, failing the handbrake.

Downshifting braking
Manual transmission vehicles can also slow down and stop by forcibly downshifting. The specific method is to directly shift into second gear, then release the accelerator and lift the clutch. At this point, the vehicle will have a feeling similar to an emergency brake. Then, you can wait for the right moment to shift into first gear. At this time, you can turn off the engine and use the compression of the engine cylinders to make the vehicle stop. If the test drive fails on some crowded or downhill sections, in order to prevent the situation from worsening, you should use obstacles such as grass piles, ditches, sand and mud heaps, rocks, etc. on the roadside to create resistance for the vehicle and stop it.

2. The tire suddenly bursts while the vehicle is in motion.
This issue has been the top concern among car enthusiasts recently. Due to the rising temperature, the road problems have reached an unprecedented level. Among all the components of the vehicle, the four wheels are the ones that come into contact with the ground the most. Netizens are worried that during daily driving, their beloved cars will suddenly burst into flames due to the high friction between the wheels and the ground, combined with the high temperature of the ground. In fact, a tire burst is the most serious and terrifying accident in all major accidents. Its specific manifestation is that the steering wheel suddenly shakes violently, followed by a loud "bang" sound, and the front of the car suddenly shakes. This situation is usually a sign of a tire burst. Tire bursts are generally divided into front-wheel bursts and rear-wheel bursts.

Front tire blowout: Grasp the steering wheel firmly with both hands, adjust the vehicle's direction, move gently, do not slam the steering wheel, do not repeatedly turn it, and do not slam on the brakes. Observe the vehicle speed. Once the speed slows down steadily, then gently turn the steering wheel to bring the vehicle to a gentle stop. Then, erect a warning sign behind the vehicle to prevent accidents.

Tire blowout on the rear wheel: The vehicle will become unstable and lean towards the side where the tire has blown out. At this point, you should stop the vehicle by applying the emergency brake, as the rear wheels of most vehicles carry relatively less weight. Since a rear tire blowout is not very serious, simply grip the steering wheel firmly.

Daily precautions:

1. Enhance your awareness of tire safety. Regularly inspect your tires, especially before long-distance driving or when entering the highway. Make sure to conduct thorough and meticulous checks. Besides tire pressure, also observe whether there are any cracks on the tire sidewall or the condition of the tire tread. If any potential problems are detected, they should be resolved promptly.
2. Regularly perform tire rotation to ensure uniform tire wear on the same vehicle. The tires should be rotated every 5,000 kilometers of driving. A four-wheel alignment should be conducted every 5,000 to 10,000 kilometers to prevent abnormal, excessive tire wear, and it is not allowed to install tires of different models or with significant differences in age on the same axle.

Vehicle skidding
Lateral skidding refers to the phenomenon where a vehicle experiences lateral swaying due to excessive torque when accelerating suddenly, braking abruptly, or starting. Vehicle lateral skidding can easily lead to accidents. When encountering such a situation during daily driving, we should not panic. By following the methods below, we can effectively control the vehicle:

When turning at high speed, the front of the vehicle may not turn according to the driver's intention, but instead keep moving forward.

At this point, simply releasing the accelerator and lightly pressing the brake will make the vehicle return to the correct path. If the turning angle is too large, slightly turning the steering wheel back can eliminate the phenomenon of insufficient steering.
1. If excessive braking is applied before entering a curve, it will cause the vehicle's load to shift forward. When the vehicle is moving at a high speed, the steering is delayed, and the driver is in a hurry to correct the direction, resulting in a skid. In this case, the brake pedal should be released, and the steering wheel should be gently turned in the opposite direction to restore the traction of the driving wheels.
2. If the emergency brake causes skidding, immediately stop the braking and turn the steering wheel in the direction of the rear wheel skid. However, the speed and extent of the steering operation must be moderate.
3. If the vehicle skids due to high speed or sudden steering, you should release the accelerator to reduce the speed. At the same time, based on the vehicle speed and the state of the skid, gently turn the steering wheel towards the side where the skid occurred to help the vehicle exit the skid condition.
