摘要:
A transmission system includes a first clutch, a second clutch, and a controller. The controller communicates with the first and second clutches and commands a gear shift. The controller calculates a torque phase time for the gear shift and determines a desired torque trajectory within said torque phase time. The controller determines on-coming torque values for the second clutch and off-going torque values for the first clutch to achieve the desired torque trajectory within the torque phase time. The controller calculates an on-coming clutch pressure based on the on-coming torque value, and an off-going clutch pressure based on the off-going torque value. The controller delays actuation of the first and second clutches to compensate for hydraulic delays.

传动系统包括第一离合器,第二离合器和控制器。 控制器与第一和第二离合器通信并进行换档。 控制器计算换档的扭矩相位时间,并确定所述扭矩相位时间内的期望转矩轨迹。 控制器确定用于第二离合器的接通扭矩值和用于第一离合器的过渡扭矩值,以在扭矩相位时间内实现期望的扭矩轨迹。 控制器基于接通转矩值计算出来的离合器压力和基于脱离转矩值的离合器离合器压力。 控制器延迟第一和第二离合器的致动以补偿液压延迟。
