Systems and methods are provided for simulating rev-matching in hybrid electric vehicles (HEVs). In particular, increased engine response is provided while downshifting during acceleration. The transmission of an HEV 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. The increased engine response can be reflected in a target engine speed that is calculated based on specific gear ratios associated with each of the simulated gears.

Sequential simulated gear ratio calculation and rev-matching in a hybrid electric vehicle

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.
