摘要： Presented are model-based control systems for operating parallel hybrid powertrains, methods for making/using such systems, and motor vehicles with parallel hybrid powertrains and model-based torque and speed control capabilities. A method for controlling operation of a hybrid powertrain includes receiving a command signal for a hybrid powertrain operation associated with a driver input and a current operating mode of the powertrain. A desired output torque for executing the powertrain operation is then determined. The method determines if a speed differential between an engine speed of an engine and a torque converter output speed of a torque converter is less than a calibrated threshold; if so, the method responsively engages a clutch device to operatively connect the engine's output member to the transmission's input member. Engine torque is then coordinated with motor torque such that the sum of the engine and motor torques is approximately equal to the desired output torque.

摘要： A method for operating a drive train of a motor vehicle, the drive train having at least one transmission (2) for carrying out different transmission gear ratios between an input shaft (21) and an output shaft (22) of the transmission (2) by selectively engaging hydraulically actuatable shift elements of the transmission (G), the drive train further having an electric machine as a drive source (1), and a hydraulically actuatable or bridgeable starting component (3) in the power path between the drive source (1) and the output shaft (22). The method includes performing a starting process of the motor vehicle driven solely by the drive source (1) with an engaged or bridged starting component (3). The method further includes limiting a drive source torque (1t) during the starting process to a maximum value dependent on a current system pressure (2p) of a hydraulic system of the transmission (2).

摘要： A vehicle includes an engine. The vehicle includes a controller configured to start a timer having a duration defined by a charge limit of a traction battery and during which the engine braking is maintained and reduce a predetermined rate of change speed limit of the engine is reduced. The starting of the timer is responsive to application of an accelerator pedal during engine braking. The controller is further configured to increase the predetermined rate of change speed limit such that engine braking is predicted based on the limit of the battery, responsive to application of an accelerator pedal during engine braking.

摘要： A power assist device may include a motor, a motor driving circuit, sensors to output signals in accordance with a rotational speed of the wheel, a memory, and a signal processor. The memory stores information of a parameter defining a transfer function that interrelates a total torque to be input to the vehicle and a rotational speed of the wheel, and an inverse transfer function thereof. Based on the inverse transfer function, the signal processor determines an estimated value of total torque from a detected value of rotational speed of the wheel. Moreover, based on the transfer function, the signal processor updates at least a portion of the information of the parameter so that, for example, an error between a detected value of rotational speed of the wheel and an estimated value of rotational speed of the wheel as determined from the estimated value of total torque is reduced.
