AutoBeta(AutoBeta.net)06/04 Report--

A Mr. Pei from Zhejiang revealed that he bought an imported Mercedes-Benz AMG C63 at the 4S store of Zhejiang Xingbao Bank on May 21 this year, and the total cost went to the 4S store four times in less than half a month. Let's see what's going on. Mr. Pei said in an interview that the car malfunctioned the next day after picking up the car. First, the engine suffered a serious setback, the stereo and the central control machine died. After 4s store debugging, the problem was improved, but there was still noise in the sound. And there was automatic braking on the highway.

Similar brakes also happened when the car was backing up. Mr. Pei also said that since picking up the car, four trips to the 4S store have failed to solve the problem, and now the car does not dare to continue to be used. Mr. Pei asked to return the car, but it was rejected by the 4S store.

Zhejiang Xingbao 4S store said in an interview with the media: the plan now is maintenance, the need to disassemble the car line, continue to detect problems and then repair the vehicle.

In this regard, Mr. Pei said that he was dissatisfied with the plan of the 4S store. There were so many problems with the car he bought less than half a month ago, and he tested it many times, but nothing could be detected. Now he can't fix it, and now he says he wants to take the car apart for testing. This is really unacceptable.

Xingbao staff explained that Mr. Pei reflected the situation of automatic braking on the highway, probably because Mercedes-Benz AMG C630 had an active lane maintenance auxiliary system, which could prevent the car from accidentally deviating from the lane and caused serious consequences. they believed that Mr. Pei's car braked automatically on the highway because the car's lane keeping system detected signs of risk. The system automatically helps the vehicle return to the original lane, but the specific situation needs to be based on the inspection report of the maintenance personnel to the system. After further communication between the two sides, Mr. Pei agreed to continue to use the vehicle and cooperate with the 4S store to observe whether there is a problem.

Well, let's take a look at the working principle of this active lane maintenance auxiliary system mentioned by the 4S store.

Active lane maintenance assistance system: when the driver is inattentive or tired may lead to accidental driving out of the lane, the system uses a stereoscopic camera to monitor whether the vehicle accidentally crosses the solid or dotted lane markings. Once this situation is identified, the system immediately warns the driver through pulsed steering wheel vibration. If the driver does not take measures, the active lane maintenance assistance system will help the vehicle return to its original lane through unilateral braking intervention. Braking intervention is usually carried out when a vehicle accidentally crosses the solid lane marking. When a vehicle accidentally crosses the dotted lane marking, it will intervene only when the radar sensor detects the risk of collision with the vehicles in the adjacent lanes, for example, a vehicle is coming head-on on the adjacent lane, a vehicle behind is overtaking the vehicle, a vehicle is driving parallel to the vehicle, and so on. If the system recognizes that the driver has taken action or operated the steering signal, the intervention operation will be suspended immediately.

For car owners, the function of active lane maintenance assistance system provides a function of assisting safe driving. of course, many car owners say that they only rely on it to remind them to dodge a bullet at a critical time, rather than handing over the driver to it. Remember that its function is called auxiliary driving, not autopilot. As for Mr. Pei's case, it is because of the active lane maintenance assistance system. Or the quality of vehicles, we will continue to pay attention to.
