US Classification:

192 13R, 192105 CP, 477 78, 477 96

Abstract:

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.

International Classification:

F16H061/16

US Classification:

477125, 477906

Abstract:

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.

International Classification:

F16H 5930
F16H 5900

US Classification:

477124

Abstract:

3A method/system for controlling upshifting in an automated mechanical transmission system (10) utilized on a vehicle preferably having an ECU (28) controlled engine brake (ECB) or inertia brake (26). When an upshift from a currently engaged ratio (GR) is required (ES>ES. sub. U/S), skip upshifts (GR. sub. TARGET =GR+N, N>1) and then single upshifts (GR. sub. TARGET =GR+1) are evaluated in sequence.

US Classification:

477 78

Abstract:

A method/system for controlling downshifting in an automated mechanical transmission system (10) utilized on a vehicle. When a downshift from a currently engaged ratio (GR) is required (ES1) and then single downshifts (GR. sub. TARGET =GR-1) are evaluated in sequence.

US Classification:

477148

Abstract:

A method/system for controlling downshifting in an automated mechanical transmission system (10) utilized on a vehicle. When a downshift from a currently engaged ratio (GR) is required (ES1) and then single downshifts (GR. sub. TARGET =GR-1) are evaluated in sequence. If throttle demand is high (THL>REF), skip downshifts are evaluated to determine if they can be completed at no greater than a reference value (ES. sub. DES =ES. sub. DES-DEFAULT +offset), which is higher than otherwise (ES=ES. sub. DES-DEFAULT) allowed.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16H 5900

US Classification:

318484

Abstract:

A control method/system for controlling the operation of an electric motor (32, 42) actuated shifting mechanism (28) is provided, which includes a procedure for periodically relieving trapped frictional forces in the shifting mechanism and associated linkages (30, 38, 40). At initiation of a shifting operation (60), or periodically (66) during a shifting operation, the level of energization of the electric motor is reduced from the full target energization level thereof (68) to a minimal level (70) for a relatively short period of time (72) and then returned to the target energization level thereof. Preferably, the level of energization is returned in a 2-step process comprising stepping the level of energization to an intermediate level (76) and then ramping the level of energization from the intermediate value to the level of full target energization thereof in a ramped fashion.
