A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.

A transmission device capable of cooperating with a dual-power source and a driving method therefor, the transmission device includes a planetary gear assembly that is driven by the dual-power source; the planetary gear assembly comprises a sun gear, a rotating inner gear ring, and a planetary gear that is engaged between the sun gear and the rotating inner gear ring; the dual-power source comprises an input shaft, the input shaft being connected to the sun gear. The direction of the rotational movement of the planetary gear about the input shaft depends on the linear velocity V1 of pitch circle movement of the rotating inner gear ring and the linear velocity V2 of pitch circle movement of the sun gear.
