CONTROL SYSTEM: Engine and CVT Integrated Control (CAN Communication Control)

For purposes including improving the feeling when shifting speeds and preventing drops in engine speed, engine output control signals are exchanged between the ECM and TCM, and real-time cooperative control is performed according to the vehicle driving conditions.
TCM sends the sudden deceleration signal, lock-up engaged signal, torque-down request signal, and other information to ECM, and also receives the torque-down permission/prohibit signals, lock-up permission/prohibit signals, accelerator position, and other information from ECM.
