HYBRID DRIVE BEHICLE CONTROL METHOD AND SYSTEM
First Claim
1. A hybrid drive vehicle control method for a hybrid drive vehicle having a prime mover, drive wheels, a hybrid mechanism having an energy storage device, and an electrical controller, the method comprising:
- generating a first hybrid mechanism torque command corresponding to a first torque component output by the hybrid mechanism, the first hybrid mechanism torque command generated using a feed-forward controller based on at least one of an actual torque output by the prime mover or a prescribed torque output by the prime mover;
generating a second hybrid mechanism torque command corresponding to a second torque component output by the hybrid mechanism, the second hybrid torque command based on a prime mover speed setpoint and a prime mover speed feedback; and
generating an output torque command for the hybrid mechanism, the output torque command based on a combination of the first hybrid mechanism torque command and the second hybrid mechanism torque command

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.
