摘要： A method of controlling lash crossing in a hybrid electric automotive powertrain. During deceleration while the powertrain is operating in electric only mode, an input is slowed to a first speed lower than an idle speed of an internal combustion engine. Lash crossing is delayed until the input has slowed to the first speed. When the first speed is zero, lash crossing is delayed until receipt of an acceleration request.

摘要： A hybrid electric automotive powertrain includes an electric machine operable in propulsive and regenerative modes. The machine has positive and negative torque limits for the propulsive and regenerative modes, respectively, to reduce potential thermal damage to the machine due to overheating. The negative and positive torque limits are reduced independently as a temperature of the machine increases. The negative torque limit may be reduced at a greater rate than the positive torque limit.

摘要： A transmission shift is timed for a hybrid electric powertrain as a function of a torque capacity of an electric machine relative to a shifting torque required to change gearings of a transmission. A vehicle is being propelled by the machine, with an engine stopped, when the shift is requested. If the machine has insufficient torque capacity to change transmission gearings, then the shift request is delayed until the engine has started.
