What does TCU mean?
1 Answers
TCU is the automatic transmission control unit, commonly used in AMT, AT, DCT, CVT and other automatic transmissions. It uses computer and power electronic drive technology to achieve vehicle automatic shifting, which can eliminate differences in driver shifting skills, reduce driver workload, improve driving safety, and enhance vehicle power and fuel economy. Composition of TCU: The TCU consists of a 16-bit or 32-bit processor, signal processing circuits, power drive modules, etc., and must pass strict electromagnetic compatibility tests. Its operating temperature depends on the installation location, typically installed in the cabin. Function of TCU: The TCU terminal device can transmit GPS location information, driving speed, vehicle data, and other information back to the system platform via wireless transmission. Users can monitor and manage the vehicle through computers or mobile phones. Impact of TCU Transmission Adjustment System: The transmission control module helps the transmission decide when and how to shift by collecting information from various sensors and the engine control module, thereby improving vehicle performance, ensuring smooth shifting, and saving fuel. The malfunction indicator lamp, also known as the engine check light, illuminates a yellow or red engine symbol on the dashboard when the control module detects a fault. This fault code indicates that the powertrain (electronic control unit) has received a request from the transmission control system (TCU) to light the malfunction indicator. After clearing a vehicle fault, it is necessary to eliminate the fault code. When erasing the fault code, it must be done strictly according to the method specified for the specific vehicle model, and the battery negative terminal should not be disconnected arbitrarily to eliminate the vehicle fault.
