A transmission control system for a hybrid-power driving system includes at least a gear shifting actuation module to control engagement of specific gearwheels and a clutch actuation module to control a clutch that couples an engine to the transmission. Gear shifts are required for each of the engine and the electric motor in the hybrid-power driving system. By selectively controlling the clutch and engagement of specific gearwheels, the transmission control system can start the engine when the vehicle is initially powered by the electric motor alone. Starting the internal combustion engine in this case switches the vehicle from a pure motor driving mode to a hybrid driving mode. Additionally, the transmission control system can start the engine when the vehicle is in a parked state, for example, to put the vehicle in a battery charging mode for the electric motor.
