Double disconnect transmission reverser with disconnect synchronizer

A control system for a transmission reverser having an output shaft, an output gear, a reverse gear, a forward clutch, a reverse clutch, and a reverse disconnect synchronizer, the control system comprising:

• one or more controllers having processing and memory architecture configured to execute control logic to control the transmission reverser in a forward mode and a reverse mode;
• one or more speed sensors for determining a speed of one or more components of the transmission reverser indicative of a vehicle speed associated with the transmission reverser, the one or more speed sensors providing a speed input to the one or more controllers;
• and
• one or more timers for determining an elapsed time period associated with a shifting operation and providing a clock input to the one or more controllers;
• wherein, in the forward mode, the one or more controllers:
• command the reverse clutch to disengage;
• command the forward clutch to engage to connect to the output gear to the output shaft such that the output gear rotates in a direction of rotation of the output shaft;
• receive and analyze the speed input and the clock input;
• and
• command the reverse disconnect synchronizer to engage or disengage at least in part, based upon the speed input being above or below a speed threshold and the clock input being above or below a time threshold such that the reverse clutch is either connected to the output gear or disconnected from the output gear;
• and
• wherein, in the reverse mode, the one or more controllers command the reverse clutch and the reverse disconnect synchronizer to engage such that the reverse shaft rotates the output gear in a reverse direction of rotation opposite the direction of rotation of the output shaft.
