Abstract: A hybrid drive vehicle control method and apparatus for a hybrid drive vehicle having a prime mover, drive wheels, a hybrid mechanism having an energy storage device, and an electrical controller is provided. The apparatus and method collect vehicle data characteristic of how the vehicle is operated, and compare the collected vehicle data to prescribed data, the prescribed data corresponding to a desired operation of the vehicle. A propulsion power limit of at least one of the hybrid mechanism or the prime mover is set based on the comparison.

Abstract: A method of operating a vehicle includes the steps of: entering a drive shaft test mode; receiving a command to position a yoke to drive the shaft; regulating the shaft speed so as to be below a predefined threshold; and determining whether a drive shaft is available based on whether an actual drive shaft speed is detected above the predefined threshold. When the detected actual drive shaft speed is above the predefined threshold, it is determined that the drive shaft is not available and the vehicle is disabled to prevent damage to the vehicle. When the detected actual drive shaft speed is not above the predefined threshold, it is determined that the drive shaft is available, and the vehicle may be operated as is typical. The methods may be performed by an controller executing program code stored on a non-transitory computer readable medium.

Abstract: A hybrid drive vehicle control method for a hybrid drive vehicle is provided. The hybrid drive vehicle includes a prime mover, drive wheels, a hybrid mechanism having an energy storage device, and an electrical controller. In accordance with the method, a prime mover reference command corresponding to a torque output by the prime mover is generated, the reference command generated using prime mover torque-based feedback control in combination with prime mover residual torque compensation. Further, a hybrid mechanism reference command corresponding to a torque output by the hybrid mechanism and applied to the prime mover is generated, the hybrid mechanism reference command generated using feedforward compensation. A hybrid mechanism feedback signal corresponding to a torque applied by the hybrid mechanism to the prime mover is also generated.
