Method for adjusting desired performance of vehicle hybrid drive, takes account of available power reserves of motors in coordinating power demand distribution between them

摘要

A coordinator (16) receives signals indicating power requirements called for by accelerator (18), automatic control system (22) or brake pedal (20), and signals to a second coordinator (26) the desired drive output (38) of the hybrid drive (100). Check signals from the IC motor (10) (crankshaft speed) and electric motor (12) (battery charge) indicate the reserve power available from each to the second coordinator, which then selects an optimum speed for the IC motor in contributing to the power demand and if necessary initiates a gear change.
