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.

Predictive transmission shifting

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 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.

High efficiency, high output transmission

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. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.
