What does TCU mean in cars?

[DaisyLynn]

The TCU in cars is the Transmission Control Unit, commonly used in automatic transmissions such as AMT, AT, DCT, and CVT, to achieve automatic gear shifting control, making driving simpler. Its main functions include: 1. Target gear decision: Based on driving environment and driver-recognized strategies, it improves vehicle economy and comfort; 2. Actuator control; 3. Fault diagnosis and fault handling. The TCU can detect certain data, such as engine speed and vehicle speed, and use this data to control the transmission for gear shifting. The shifting logic is calibrated by the car manufacturer's engineers through test driving experiments, data collection, user operating conditions, and targeted consumer groups. Good shifting logic can understand the driver's intentions.
