    • A method for effecting a kickdown shift in a transmission of an automotive vehicle controls turbine speed change based on a continuous desired acceleration calculation. The method determines an initial speed of a turbine that transmits torque between an engine and a plurality of gears through a plurality of releasing and engaging elements. A target speed of one of the plurality of gears is determined. A desired time required to increase the turbine speed to the target speed is determined. A desired acceleration of the turbine is calculated according to the initial speed, the target speed, and the desired time. Turbine speed change rate is controlled through controlling the clutch torque of one or more of the releasing and engaging elements based on the desired acceleration.
    • 用于实现机动车辆的变速器中的降档变速的方法基于连续期望的加速度计算控制涡轮机速度变化。 该方法确定通过多个释放和接合元件在发动机和多个齿轮之间传递扭矩的涡轮机的初始速度。 确定多个齿轮中的一个的目标速度。 确定将涡轮速度增加到目标速度所需的期望时间。 根据初始速度,目标速度和期望时间计算涡轮机的期望加速度。 基于期望的加速度,通过控制一个或多个释放和接合元件的离合器扭矩来控制涡轮变速率。

    • A transmission control system includes a first gear engagement element that receives fluid and engages a first gear. An electromagnetic actuator selectively interrupts fluid flow to the first gear engagement element based on a duty cycle of a control signal. A control module adjusts the duty cycle so that a fluid flow rate continuously decreases as the first gear engagement element produces a first torque sufficient to hold the first gear. The flow rate is based on a first estimated volume of the fluid necessary for the first gear engagement element to produce the first torque. The control module computes a current volume of the fluid when the first gear engagement element produces the first torque. The control module adjusts a value of the first estimated volume for subsequent transmission control when a difference between the current volume and the first estimated volume is greater than a predetermined volume.
    • 变速器控制系统包括接收流体并与第一档啮合的第一齿轮啮合元件。 电磁致动器基于控制信号的占空比选择性地中断流到第一齿轮啮合元件的流体流。 控制模块调整占空比,使得当第一齿轮接合元件产生足以保持第一档位的第一扭矩时,流体流速连续减小。 流量基于第一估计体积的第一齿轮接合元件产生第一扭矩所需的流体。 当第一齿轮接合元件产生第一转矩时,控制模块计算流体的当前体积。 当当前音量与第一估计音量之间的差大于预定音量时,控制模块调节用于后续发送控制的第一估计音量的值。
