摘要:
A method and system are provided for controlling the operating temperature of a torque converter during torque converter stall conditions. The torque converter has a pump rotatably driven by an internal combustion engine and a rotatable turbine fluidly coupled to the pump. The system first determines whether the torque converter is currently in a torque converter stall condition, and, if so, determines a slip speed as a difference in rotational speeds between the pump and the turbine, determines an engine output torque limit as a function of the slip speed and a desired slip speed, and controls the operating temperature of the torque converter by limiting output torque produced by the engine based on the engine output torque limit.
