Reasons for the public DSG problem and evaluation of Solutions
  • Automotive

In the case of the present case, the problem of the popular DSG double clutch transmission is mainly on the two key points of overheating protection and related software problems caused by excessive wear and tear, and the related problems which we often appear below are explained one by one. 1, power sudden interruption: the public DSG in the start stage and below a certain speed, for example, in the case of traffic jam, its dry DSG double clutch may always be in the semi linkage sliding grinding state, which will cause the clutch temperature to rise quickly, in order to protect the clutch from damage, TCU will control the clutch completely separate, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated, until the clutch is completely separated. When the temperature falls to a safe range, this strategy will directly lead to a power interruption for a certain period of time, that is, the so-called overheating protection leads to power failure. To solve this problem, the public can consider the wet DSG to replace the dry DSG in an all-round way. Although the dry working efficiency is higher and the speed is faster, the wet clutch can take the heat through the transmission oil to solve the problem. 2, the sudden acceleration of the vehicle: when the Volkswagen DSG is in the starting stage and below a certain speed, the engine will have the strategy of increasing twisting and rising speed in the starting conditions. If the control is not good, the vehicle will suddenly accelerate rapidly. If you want to solve this problem, you can only solve it by means of software upgrades. The public can collect relevant data, update and upgrade software. 3, dead block: this phenomenon may be due to TCU detection of a gearbox failure, at this time to protect the transmission, the transmission will be fixed in a certain gear, to ensure that it is not paralyzed on the road, but also to make do not be able to go home or maintenance station, the so-called "limp home function" of automatic transmission. This kind of fault is usually caused by circuit fault, and the transmission itself usually does not have any problems. Volkswagen's DSG locking gear may be caused by the detection of the clutch of a certain shaft, so it is necessary to overhaul the automobile circuit. Some people say that the problem of the public DSG in China is that the dry type dual clutch transmission does not fully estimate the characteristics of the Chinese market (because of the serious and frequent shift of traffic in China's road traffic jam). This is one of the reasons for the frequent occurrence of the mass DSG event, but the life of the consumer is only once. No one wants to be the protagonist of the accident. It also hopes that the Volkswagen car can properly solve the related problems and give the consumer a responsible answer.
