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.

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.

Abstract translation: 描述了采用多个推进扭矩致动器的动力系统系统。 用于控制动力系统的方法包括解释驾驶员请求，包括基于对加速器踏板和制动踏板的驾驶员输入来确定驾驶员扭矩请求和再生制动请求。 根据驱动器转矩请求和再生制动请求确定期望的请求。 基于期望的请求，驾驶员扭矩请求和用于确定上下输出扭矩限制的先前驱动器扭矩请求来协调动力系统的扭矩限制，并且将上下输出扭矩限制与系统约束相结合以产生 最终扭矩要求。 采用最终的扭矩请求来确定用于推进力矩致动器的扭矩指令，并且推进扭矩致动器基于用于推进扭矩致动器的扭矩指令来控制。
