摘要： 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.

摘要： A method for controlling brakes of an automatic transmission including a first brake arranged in parallel with an overrunning brake between a planet pinion carrier and a housing, includes using the overrunning brake to provide brake torque equal to or less than a reference brake torque under positive torque conditions, increasing a torque capacity of the first brake when brake torque is greater than the reference brake torque, and fully engaging the first brake.
