International Classification:

B60K 4102

US Classification:

477 78, 701 56, 74336 R

Abstract:

Simulated or âmockâ continuously variable transmission shift strategies are used in an electromechanically actuated automotive transmission having reduced ratios steps in its upper ratio ranges. In one described embodiment, a 12-speed truck transmission consists of a five-speed main section and an auxiliary section that includes splitter and range sub-sections to provide the 12 ratios. Separate shift strategies are directed to fuel economy and power optimization modes; driver throttle demand determines the mode. Both strategies are targeted to the upper gear ratios, which represent the ratios subject to approximately ninety percent (90%) of vehicular operation. In the described embodiment, the applicable affected ratios are gears In the described embodiments, the shift strategies are carried out by embedded software subject to the command of an electronic power train control module. Both strategies are operated as direct functions of engine torque, transmission input shaft speed, and road speed.

Abstract:

A continuously variable transmission for use with motor vehicles includes an ECU, an automated gear unit, a variator, an input gear set, an input fixed ratio element and an output fixed ratio element. The automated gear unit has multiple selectively engaged gear ratios and engages one of the gear ratios responsive to commands from the ECU. The variator varies a ratio of torque between its input and outout shafts responsive to commands from the ECU. The variator output shaft is connected to the gear unit input shaft. The input gear set is connected to the variator input shaft. The input fixed ratio element reduces torque from the input gear set to the variator, and is disposed between the input gear set and the variator input shaft. The output fixed ratio element increases the torque from the variator, and is disposed between the variator output shaft and the gear unit input shaft.

US Classification:

475208

Abstract:

A dual mode continuously variable transmission for use with motor vehicles includes a transmission input shaft, a transmission output shaft, and a variator disposed between the transmission input shaft and the transmission output shaft. A mixer gear set is operably disposed between the transmission input shaft and the variator output shaft. A clutching element is operably disposed between the input shaft the mixer gear set. The variator is configured to continuously vary a ratio of input torque to output torque between the variator shafts responsive to commands from an electronic control unit. The variator input shaft is drivingly connected to the input shaft and the variator output shaft is drivingly connected to the output shaft. The clutching element selectively connects and disconnects the input shaft and the mixer gear set to operate the transmission in a power splitting mode of operation and a variator only mode of operation. An electronic control unit incorporates logic rules by which the clutching element maintains the transmission in a variator-only mode of operation in a first vehicle speed range, and maintains the transmission in a power splitting mode of operation in a second vehicle speed range greater than the first vehicle speed range.
