Abstract
Systems and methods are provided for simulating rev-matching in hybrid electric vehicles (HEVs), e.g., HEVs having a two motor hybrid system transmission. In particular, increased engine response is provided while downshifting during acceleration. The two-motor hybrid system transmission may include an electronic control unit that controls the speed of the engine to simulate gears, and increases the speed of the engine responsive to a driver using the gear selector to shift from one of the simulated gears to a lower one of the simulated gears, thereby providing the desired rev-matching experience.
