    摘要: A vehicle comprises an electric machine configured with at least one controller issuing torque commands with the use of a voltage bus. The controller may be configured to respond to a torque requests based on multiple vehicle system inputs including vehicle speed, position of the accelerator pedal and brake pedal, and various other vehicle data. The controller may respond to a torque request that exceeds a threshold value by issuing torque commands for the electric machine based on a speed of the electric machine and a voltage on the bus. Based on the speed of the electric machine and voltage on the bus, the controller may issue a constant torque output by the electric machine as the speed and voltage vary. Calculating a ratio using speed of the electric machine to voltage on the bus to determine torque capability may result as a constant torque when the ratio is constant.

    摘要: An engine shaft of an engine, rotatable shafts of motor generators and a drive force output shaft are interconnected with each other through a drive force transmission arrangement. An ECU computes a torque command value of each of the motor generators through use of an equation of torque equilibrium, which corresponds to the drive force transmission arrangement, based on an engine shaft demand motor generator torque and an output shaft demand motor generator torque.

    摘要: A cranking torque control apparatus (100) is mounted on a hybrid vehicle provided with: an engine (11), a motor (MG1) coupled with the engine and capable of cranking the engine, and a battery (21) capable of supplying an electric power to the motor. The cranking torque control apparatus is provided with: a setting device (22) capable of setting an output limit value which is a limit value for the electric power outputted from the battery in accordance with an electric power deviation when the motor cranks the engine; and a controlling device (22) for controlling said setting device not to set the output limit value under a condition that a voltage of the battery falls below a lower limit voltage associated with the battery due to resonance of the engine or due to a first fire of the engine.

    摘要: A system includes a hybrid power train having a combustion torque device, an electrical torque device, a driveline mechanically coupled to the torque devices, a battery that exchanges energy with the driveline, and a torque input device that provides a torque request. The hybrid power train is at least partially parallel. The system includes a controller having modules to execute operations for rate control of the hybrid power train. A battery protection module determines a battery protection charge rate limit, a power train protection module determines a power train protection torque change limit, and a torque request module determines the torque request. A rate control module provides a torque balance parameter in response to the limits and the torque request. A torque control module provides an electrical torque and a combustion torque to the driveline in response to the torque balance parameter.
