POWER REGENERATION OPTIMIZATION IN A HYBRID VEHICLE

摘要

A hybrid controller unit includes a detection module, a gear-hold module, a gear-skip module, and an optimizing module. The detection module is structured to detect a deceleration event. The gear-hold module is structured to determine whether a certain gear of a transmission should be maintained for a certain period of time in order to optimize power regeneration during the deceleration event. The gear-hold module is also structured to generate a gear-hold request. The gear-skip module is structured to determine whether the transmission should skip a gear in order to optimize power regeneration during the deceleration event. The gear-skip module is also structured to generate a gear-skip request. The optimizing module is structured to receive the gear-hold request and the gear-skip request and generate a transmission command to be sent to a transmission control unit for actuation.

1. An apparatus, comprising:
a detection module structured to detect a deceleration event in a hybrid vehicle; a gear-hold module structured to generate a gear-hold request, the gear-hold request structured to maintain a current gear of a transmission for the hybrid vehicle for a gear-hold duration responsive to the detection of the deceleration event; a gear-skip module structured to generate gear-skip request, the gear-skip request including a downshift gear destination for the transmission responsive to the detection of the deceleration event; and an optimizing module structured to generate a transmission command for use with the transmission, wherein the transmission command is based on at least one of the gear-skip request and the gear-hold request.
