AI Technical Summary
Technical Problem
Variations in the speed and torque of the transmission system lead to inefficient and unreliable operation of the vehicle subsystems, especially when the engine is idling and cannot provide sufficient speed to operate the vehicle subsystems efficiently.
Method used
A digital power output system is adopted, which uses a planetary gear mechanism and actuator to control the speed of the sun gear. By modifying the transmission ratio of the planetary gear mechanism, the output shaft speed is kept matched with the desired output shaft speed.
Benefits of technology
Maintaining a stable output shaft speed within the range of input shaft speed variation improves the operating efficiency and reliability of the vehicle subsystem and reduces energy consumption.

Abstract
A digital power take-off system includes an input shaft and an output shaft connected to a planetary gear mechanism. An actuator is mechanically coupled to the planetary gear mechanism to mechanically control the rotational speed of the output shaft. An output shaft sensor detects the output shaft rotational speed. A controller circuit receives the desired output shaft rotational speed, receives the output shaft rotational speed from the output shaft sensor, and determines the difference between the rotational speeds. Based on the determined differential actuator output operating parameters, the controller circuit causes the actuator to modify the gear ratio of the planetary gear mechanism to maintain the desired output shaft rotational speed within a range of the input shaft rotational speed.
