Mr. Xue of Henan Province drove at a high speed. On the way, he called the police and said that the cruise at a fixed speed was out of order. He ran at a speed of 120 yards per hour. The traffic police rescue ended with a scene, which triggered a heated discussion on the Internet. It can be said that it's the Chinese version of the speed of life and death. So what's the process like? What's the cruise control system? Let's have a detailed understanding of sihai.com.
@Han Han commented on Weibo: This is beyond his understanding of automobile and driving knowledge. Even if the electronic brake system fails, it will hardly happen that the brake is completely useless and then useful. The owner may exaggerate.
The situation is similar to that of Toyota brake door on high-speed in the United States. The former brake pedal is stuck and can't slow down. It ended in tragedy by calling 911 for help. The latter is a Mercedes Benz in 120 km / h cruising state, braking and cruise control are not working to call 110 for help. Fortunately, under the emergency rescue and after-sales operation of high-speed traffic police in Henan and Shaanxi provinces, Mercedes Benz finally stopped safely after losing control for nearly an hour or about 100 km.
What happened?
At about 8:00 p.m. on March 14, 2018, Mr. Xue of Jiaozuo drove a Mercedes Benz c200l car. Driving along Lianhuo Expressway from east to west, he drove alone on the expressway from Luoyang section of Lianhuo expressway, and then started the constant speed cruise mode, with a speed of 120 km / h all the way west.
After passing Sanmenxia east station smoothly, Mr. Xue needed to switch manual driving, but he found a fatal situation: the brake and gear systems could not operate normally, and the 120 km / h car could not switch back. This means that he will face the test of life and death as long as there are any obstacles in front that need to be slowed down.
Mr. Xue called Mercedes Benz for after-sales service many times during the driving process, and operated according to various solutions provided by him, but failed & hellip; & hellip;
In the period from Sanmenxia to the boundary between Henan and Shaanxi, Mr. Xue tried a way. It is to unbuckle the safety belt and open the door a little while while driving, which can force the vehicle to slow down. But it's very unstable and dangerous. So Mr. Xue closed the door again.
At 9:35 p.m., desperate, he called 110 for help. Police quickly cleared three etc lanes of the toll station and ensured the smooth passage of the central square of the provincial border station. At the same time, the police communicated with Shaanxi high-speed traffic police and opened all the lanes into Shaanxi.
Less than one minute after everything was ready, at 10:25 p.m. that night, according to the guidance of the traffic police, Mr. Xue drove a Mercedes Benz car from the etc channel of Henan Shaanxi border toll station to pass through the provincial border station without obstacles and left Henan.
It's impossible to imagine how to 'stimulate' the people who deal with the scene.
Mercedes Benz after sales actually uses the backstage operation car to finally no longer lose control
It's almost an hour since Mr. Xue called the police. In the runaway car, Mr. Xue has no choice but to wait and pray. How can the car stop?
The gratifying news soon came: after entering Shaanxi, Mercedes Benz after-sales finally operated in the background, which made the Mercedes Benz, which was out of control for 100 kilometers on the expressway and nearly an hour out of control, return to normal control, stop at the 923km section of Lianhuo Expressway safely, and be pulled away from the expressway safely from Huayin station.
In addition to exclamation that the car owners are bold and cautious and calm in dealing with matters in crisis, appreciation of the high-speed traffic police of Henan and Shaanxi provinces for actively clearing out the emergency life channel for out of control vehicles as a timely coordination, it is even more surprising that the last thing that stops out of control vehicles at high-speed is Mercedes Benz's after-sales operation through the background. Why has Mercedes Benz such a high level of black technology never been publicized?
Naobu imagines that at that time, Mercedes Benz after-sales took a laptop and entered a line of code on the keyboard with the skillful action of hackers, and finally the vehicle was completely controlled & hellip; & hellip; haha, this is not a science fiction movie, it really happened on March 14!
What is cruise control?
Speed cruise system, abbreviated as CCS, is also called speed control system. Its function is to drive automatically according to the speed of the owner, without calling on the accelerator, so it is also called autopilot system.
Why does Mercedes Benz's cruise control system and brake fail at the same time? Is this due to Mercedes Benz's technical defects or the improper use of the car owner? We must understand this.
Some insiders believe that the brake system and constant speed cruise are separate. The constant speed cruise only locks the accelerator, which will not cause the brake failure due to the failure of constant speed cruise. This will not happen unless the circuit system of the whole car has problems. However, the above accidents happened to be the failure of cruise control and the failure of brake at the same time, which shows that the possibility of cruise control and brake system failure at the same time due to circuit system failure still exists.
According to the current set principle of automobile electronic system, this kind of thing can happen in Benz unless ECU fails and the brake, parking, cruise and transmission fail at the same time
