    • A transmission system (36) is disclosed as having a transmission (24) configured to receive torque output from a power source (22) and to drive a traction device (14), and an input device (18). The transmission system may also have a control module (27) configured to reference a signal from the input device with a map to determine a corresponding speed of the power source, and to determine a margin between an actual and a maximum available torque output of the power source at a current speed. The control module may also be configured to determine a delay time threshold based on the margin, to selectively adjust a speed of the power source mapped to the maximum displaced position of the operator input device based on the margin, and to selectively adjust fueling of the power source at a current displacement position of the operator input device and operation of the transmission based on the signal and the map.
    • 传输系统(36)被公开为具有被配置为接收从电源(22)输出的扭矩并驱动牵引装置(14)的变速器(24)和输入装置(18)。 传输系统还可以具有控制模块(27),其被配置为使用映射来参考来自输入设备的信号,以确定电源的对应速度,并且确定在该功率源的实际和最大可用转矩输出之间的裕量 电源以当前速度。 控制模块还可以被配置为基于余量确定延迟时间阈值,以基于余量选择性地调整映射到操作者输入装置的最大位移位置的电源的速度,并且选择性地调节 在操作者输入装置的当前位移位置处的电源和基于信号和地图的传输的操作。
