High efficiency, high output transmission having an aluminum housing

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.

A navigation system is described for a vehicle equipped with an autonomous driving system. The navigation system includes a human-machine interface with a display and a user control, and an electronic controller. The controller is configured to calculate a plurality of travel routes from a determined starting point to a defined destination point. The controller determines which portions of each travel route will utilized automated driving operation and which portions will utilized manual driving operation. Based on an input received from the user control, the controller defines an automatic-manual driving preference ratio indicating a driver preference for an amount of manual driving operation relative to an amount of automatic driving operation. The controller automatically selects a route from the plurality of travel routes that most closely matches the defined automatic-manual driving preference ratio and outputs the selected route on the display.
