摘要: A system/method for shift restraint control and controlling a transmission input speed or an engine output speed. An automobile may include an acceleration input, a throttle unit, an engine, a torque converter, a transmission, and an electronic control unit (ECU), and a plurality of sensors. The ECU may reduce inertia loss, engine noise, and non-linear acceleration feeling by controlling the engine speed or transmission input speed in an initial shift mode, an inertia hold mode, a return mode, and/or a second shift mode. Drive force is maintained with throttle compensation, and fuel economy is maintained or improved due to the reduction in inertia loss. The ECU may limit an initial downshift using a maximum guard value and subsequently control a rate of increase of the transmission input speed or engine output speed using increments until a target is reached or a cancel condition is met.
