  • Patent number: 10040439
    Abstract: A powertrain system employing multiple propulsion torque actuators is described. A method for controlling the powertrain system includes interpreting a driver request, including determining a driver torque request and a regenerative braking request based upon driver inputs to an accelerator pedal and a brake pedal. A desired request is determined based upon the driver torque request and the regenerative braking request. Torque limits for the powertrain system are coordinated based upon the desired request, the driver torque request, and a previous driver torque request to determine upper and lower output torque limits, and the upper and lower output torque limits are combined with system constraints to generate a final torque request. The final torque request is employed to determine torque commands for the propulsion torque actuators, and the propulsion torque actuators are controlled based upon the torque commands for the propulsion torque actuators.

  • Patent number: 9796372
    Abstract: A method for controlling a powertrain of a vehicle includes calculating, via a controller, an optimal torque target for the powertrain as a function of system limits of the vehicle. The method includes commanding, via transmission of an output torque signal, an actual output torque of the powertrain to pursue or follow the calculated optimal torque target during a steady-state torque request condition. Additionally, the method includes detecting a predetermined vehicle event during the steady-state torque request condition, and shaping the output torque signal via the controller. A variable gain factor may be used in response to detection of the predetermined vehicle event to allow the output torque signal to temporarily deviate from the calculated optimal torque target during the steady-state torque request condition. A powertrain has an engine, an electric machine, and a controller programmed to execute the method.

  • Publication number: 20170297553
    Abstract: A method for controlling a powertrain system in response to a command to execute a multi-state shift event for the transmission includes determining an initial output torque limit and determining an initial commanded output torque based upon the initial output torque limit. The powertrain system is controlled to generate torque in response to the initial commanded output torque prior to completion of a first state transition of the multi-state shift event that includes a commanded torque reduction. After completion of the first state transition of the multi-state shift event that includes the commanded torque reduction, a torque ramp rate is determined, and the initial commanded output torque is adjusted based upon the torque ramp rate. The powertrain system is controlled to generate torque in response to the initial commanded output torque and the adjusted initial commanded output torque during a remainder of the multi-state shift event.

  • Patent number: 9676294
    Abstract: A method of managing an operating state of an electrified powertrain includes a controller identifying a plurality of available operating regions defined by at least one available operating state of the powertrain, each operating region representing a distinct range of operating conditions. The available operating regions include an avoidance region defining a plurality of unwanted operating conditions and separating a first allowable operating region from a second allowable operating region such that the first and second allowable operating regions are noncontiguous. The method identifies at least one ideal operating condition in each of the available operating regions, determines a preferability factor and stabilization factor for each of a current and each of the ideal operating conditions, and arbitrates the factors to identify one of the current and ideal operating conditions as an optimized operating condition to produce a required parameter value.

  • Patent number: 9669835
    Abstract: A method for controlling a powertrain includes, in response to an output torque request that includes deceleration, operating an internal combustion engine in a fuel cutoff state and in a cylinder deactivation state, controlling a clutch of a torque converter in an activated state, and operating an electric machine in a regenerative braking state. A state of the powertrain related to engine speed is monitored. The internal combustion engine is commanded to transition from the cylinder deactivation state to an all-cylinder state and the electric machine operates in the regenerative braking state including ramping down magnitude of regenerative braking torque when the engine speed is less than a first threshold speed. The torque converter clutch is commanded to a released state when the engine speed is less than a second threshold speed, with the first threshold speed being greater than the second threshold speed.

  • Patent number: 9624847
    Abstract: A method for controlling operation of a multi-mode powertrain system includes periodically determining a power cost difference between a first power cost and a second power cost. This includes determining the first power cost associated with operating the powertrain system with the engine operating in a presently commanded engine state in response to an operator torque request and determining the second power cost associated with an expected powertrain operation with the engine operating in a non-commanded engine state in response to the operator torque request. The first power cost is compared with the second power cost, and successive iterations of the periodically determined power cost difference between the first power cost and the second power cost are integrated to determine an integrated power cost difference. A transition to the non-commanded engine state is commanded when the integrated power cost difference is greater than a threshold.

  • Patent number: 9493063
    Abstract: A control-module implemented method for controlling a powertrain system comprising an internal combustion engine, at least one electric machine, a high-voltage battery and an electro-mechanical transmission operative to transmit torque to a driveline includes monitoring a state of charge (SOC) of a high-voltage battery configured to provide stored electrical power to a first electric machine, a second electric machine and at least one auxiliary load. A trickle-charging event is enabled only when the SOC of the high-voltage battery is less than a first SOC threshold. The trickle-charging event activates the first clutch coupled to a first planetary gear set. The trickle-charging event further coordinates a torque capacity of the activated first clutch and a charging set of torque commands between the engine, the first electric machine and the second electric machine to establish a net zero output torque condition.

The method includes determining an initial state transition threshold and an associated hysteresis band for an operating parameter related to the control variable. The hysteresis band is decayed based upon operation in a present state of the control variable for powertrain element, and a preferred control variable for the powertrain element is selected based upon a comparison of the operating parameter and the initial state transition threshold accounting for the decayed hysteresis band for the operating parameter. The element of the powertrain system is controlled to the preferred state for the control variable.
