Structures and methods herein insert one or more parallel “recessive nulling” driver impedances across a controller area network (CAN) bus starting at the time of a dominant-to-recessive data bit transition and extending for a selected recessive nulling time period. Doing so increases a rate of decay of a CAN bus dominant-to-recessive differential signal waveform, permits a shortened recessive bit time period, and allows for increased CAN bus bandwidth. Various modes of operation are applicable to various CAN bus node topologies. Recessive nulling may be applied to only the beginning portion of a recessive bit following a dominant bit (“LRN mode”) or to the entire recessive bit time (“HRN mode”). And, some embodiments may apply LRN operations to some recessive CAN frame bits and HRN operations to others.

A controller predicts a requested state of charge / discharge corresponding to a future run of a hybrid vehicle. If it is predicted that the hybrid vehicle will be stopped and restarted, or will be greatly accelerated and therefore that a request for a great discharge will be outputted in the future, the controller increases a target SOC of an HV battery to increase the value to which the charge of the HV battery will be converged in preparation for the great discharge. If it is predicted that a great regenerative electric power will be generated by a vehicle deceleration and therefore that a request for charging will be outputted, the target SOC is reduced, and the amount of charge in the HV battery is reduced, so that the regenerative power generated can be efficiency recovered.
