Abstract

A vehicle transmission can perform predictive shifting. Road grade and vehicle path data can be employed to identify a future change in road grade such as a hill. A change in speed relative to a vehicle cruise speed can be estimated or predicted in view of the change in road grade and a current gear. If the change of speed is determined to be outside a performance bound, shift recommendation can be determined to maintain vehicle cruise speed within the performance bound. A controller can alter default gear selection of the transmission in response to receipt of the shift recommendation.

Abstract

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.

Abstract

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

Abstract

A method of shifting an automated transmission in a vehicle comprises tracking vehicle parameters and determining a current gear selection. An upshift threshold can be determined for the current gear selection. Future gradient conditions are determined in a lookahead distance and are processed to determine a first percentage of future conditions that are above a selected gradient threshold. The first percentage of future conditions is compared to a selected first percentage limit to determine that the first percentage of future conditions is within the first percentage limit. The upshift threshold for the current gear selection is adjusted to change the vehicle parameter at which the vehicle transmission shifts from the current gear selection to the adjacent gear. The automated transmission is computer-controlled to shift to the adjacent gear according to the adjusted upshift threshold. A downshift threshold can also be adjusted.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

Abstract

A system for operating a dual clutch transmission, including launch/creep controller, shift logic, and a clutch control assembly. The shift logic is configured to intercept a torque command including a target clutch torque from the launch/creep controller as it transmits the target clutch torque to the clutch assembly. The shift logic engages a preparation phase that increases torque on an on-coming clutch to a prefill torque. The shift logic then engages a torque phase that transfers torque between the off-going clutch and the on-coming clutch by simultaneously decreasing the off-going clutch torque and increasing the on-coming clutch torque. The off-going clutch and the on-coming clutch remain in a slipping state that maintains the target clutch torque during the transfer.

• F16H 63/00 - Control outputs to change-speed- or reversing-gearings for conveying rotary motion

Abstract

A vehicle powertrain comprising a multiple speed transmission with ratio range gearing is disclosed. The range gearing provides increased ratio coverage. A transition between a low speed range and a high speed range is achieved with no torque interruption whereby a gear ratio shift between the highest gear ratio in the low speed range and the lowest gear ratio in the high speed range occurs in a seamless fashion.

IPC Classes  ?

• F16H 3/08 - Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion without gears having orbital motion exclusively or essentially with continuously- meshing gears, that can be disengaged from their shafts
• F16H 37/02 - Combinations of mechanical gearings, not provided for in groups comprising essentially only toothed or friction gearings
• F16H 3/44 - Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion using gears having orbital motion

Abstract

A dual friction clutch assembly for a multiple-ratio transmission comprises separate friction disks of the assembly separately connected to each of two torque input shafts for the transmission. Two torque flow paths for the torque input shafts are defined in part by pre-engaged transmission clutches.
