Abstract
A method for controlling a vehicle driveline includes determining, for current vehicle operating conditions, an initial engine output torque, at which the driveline meets predetermined structural criteria, establishing a factor that varies with torque converter slip, determining an engine torque limit by multiplying the factor corresponding to a current torque converter slip by the initial engine output torque, and limiting torque produced by an engine connected to the driveline to the engine torque limit.
