The present invention relates to a self-protection system of an automotive transmission system and a control method thereof, comprising a transmission control unit (TCU), an engine management system (EMS), an instrument module (ICM) and a CAN bus. The TCU is a main controller, and is used to perform transmission control and self-protection control on the transmission. The EMS is used to perform torque output control according to a torque protection request sent by the TCU. The ICM is used to control a transmission indication lamp according to the a transmission indication lamp request sent by the TCU. The TCU, the EMS, and the ICM are connected for communication through the CAN bus. A self-protection system of an automotive transmission system and a control method therefor, said system comprising a transmission control unit (TCU), an engine management system (EMS), an instrument cluster module (ICM), and a CAN bus. The TCU is the main controller, and is used to perform transmission control and self-protection control on the transmission. The EMS is used to perform torque output control on the basis of a torque protection request sent by the TCU. The ICM is used to control a transmission indication lamp on the basis of a transmission indication lamp request sent by the TCU. The TCU, the EMS, and the ICM are connected for communication through the CAN bus. The control method comprises three protection modes: primary shaft clamping pressure protection calculation, secondary shaft clamping pressure calculation, and steel belt slip protection, the protection increasing from one level to the next. |
