摘要: A motor vehicle has at least two drive motors, at least one of which is an electric motor, a high-voltage accumulator, and an automatic transmission which has at least one fixed gear ratio and at least one power-split gear ratio for transmission ratio adjustment starting from the at least one fixed gear ratio. The motor vehicle includes an electronic control unit having a speed control module which can be activated during a change of transmission ratio. The speed control module is designed in such a way that a setpoint speed is calculated in advance, by which setpoint speed both the speed gradient and also the speed curvature can be limited, the target speed of the at least one drive motor being continuously compared with a maximum allowed speed gradient and with a maximum allowed speed curvature.

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.

摘要: A method is described for operating a vehicle fitted with a continuously variable transmission (CVT) and having a lever for varying the transmission ratio of the CVT to permit the vehicle operator to vary the vehicle wheel speed. In the invention, the transmission ratio of the CVT is limited to a value dependent upon at least one of the prevailing engine speed and the rate of change of the engine speed.

摘要: A method of controlling a multiple step downshift is disclosed. Two offgoing shift elements are released and two oncoming shift elements are engaged to complete the downshift. During a first phase of the downshift, one of the offgoing shift elements controls the rate of increase of input shaft speed. During a second phase of the downshift, one of the oncoming shift elements controls the rate of increase of the input shaft speed. The method computes target torque capacities such that output torque and input shaft acceleration are continuous during the transition between phases. Furthermore, the method computes target torque capacities such that both oncoming clutches reach zero relative speed simultaneously as the input shaft reaches the final speed ratio.

摘要: A speed change system for work vehicle having a continuously variable transmission device selects a first change gear ratio which is set larger than a smallest change gear ratio, when an engine rotational speed is a first set rotational speed which is set equal or close to an idling rotational speed of an engine; retains the change gear ratio of the continuously variable transmission device at the smallest change gear ratio, when the engine rotational speed is equal to or above a second set rotational speed set on a high-speed side relative to the first set rotational speed; and makes the change gear ratio of the continuously variable transmission device larger between the first change gear ratio and the smallest change gear ratio, as the engine rotational speed at that moment becomes lower, when the engine rotational speed is between the first and second set rotational speeds.

摘要: A transmission configured with a speed change control unit which, when upshifting the speed in an accelerator on condition, executes an engagement control including a torque phase control after executing a filling control, which controls the hydraulic control unit in such a way that a hydraulic servo of the engagement side frictional engagement element is filled with hydraulic oil, and a standby control, which controls the hydraulic control unit in such a way that hydraulic pressure for the hydraulic servo is maintained at a preset standby pressure. A correction unit is configured to correct at least one of an execution time of the filling control and the standby pressure to an increment side when a fluctuation in a rotational acceleration of the input shaft exceeding a preset determination reference is detected after the standby control.
