    摘要: A vehicular transmission system is disclosed that includes an engine, a transmission having an input shaft, a master friction clutch for drivingly connecting the engine to the transmission, an inertia brake for selectively controlling rotation of the input shaft, and at least one control unit. The control unit includes logic rules that selectively disable operation of the inertia brake in response to a system operating condition during at least one mode of operation of the vehicular transmission system. The system also includes at least one input corresponding to a system operating condition and at least one output corresponding to a command to log a fault or disable operation of the inertia brake in response to the system operating condition during the at least one mode of operation. A control system and method for operating the vehicular transmission system are also disclosed.

    摘要: A control strategy for an electronically controlled X-Y shifting mechanism for a vehicle transmission which takes advantage of the extra supply voltage available on European vehicles while maintaining commonality with U.S. shifter systems. A variable voltage pulse width modulated duty cycle percentage is maintained at or below a 50% nominal value to make the 24V source appear as a 12V source, allowing commonality in X-Y shifting mechanism hardware and basic control algorithms for both 12V and 24V vehicle systems. However, this percentage is increased to greater than the nominal 50% limit when the available supply voltage drops below 24V, as well as between an initial movement of the shift finger and engagement of the finger with a shift block, in order to provide faster motor acceleration to obtain top speeds quicker and during low force but top speed movement conditions.

    摘要: A vehicular transmission system is disclosed that includes a prime mover, a transmission having at least one mode of operation where the transmission is selectively shifted into a lower gear ratio as vehicle speed decreases, a master friction clutch for drivingly connecting the prime mover to the transmission, and at least one control unit. The control unit includes logic rules that selectively prohibit the transmission from being shifted into a lower gear ratio in response to a system operating condition during the at least one mode of operation. The system also includes at least one input corresponding to a system operating condition and at least one output corresponding to a command to prohibit the transmission from being shifted into a lower gear ratio in response to the sensed system operating condition. A control system and method for operating the vehicular transmission system are also disclosed.
