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 method of controlling gear shifting of a hybrid vehicle including an engine, a motor, and a stepped transmission includes predicting a requested torque reduction amount requested by the engine and the motor when there is a request to shift gears of the transmission, determining whether to realize the predicted requested torque reduction amount by reducing motor torque or applying counter torque, as a result of the determining, when it is not possible to realize the predicted requested torque reduction amount, determining an operating point correction amount for increasing an available torque reduction amount of the motor, and determining whether to perform first gear-shifting control in consideration of efficiency of the first gear-shifting control of increasing the motor torque and reducing engine torque by the operating point correction amount before an actual requested torque reduction amount is input.

Abstract: A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

Abstract: A vehicle travel control apparatus configured to control an actuator for driving a vehicle with a self-driving capability so that the vehicle follows a forward vehicle in front of the vehicle. The vehicle travel control apparatus includes a travel state detector configured to detect a traveling state of the forward vehicle, and an electric control unit having a microprocessor and a memory. The microprocessor is configured to perform determining whether the forward vehicle is cruising based on the traveling condition detected by the travel state detector, and controlling the actuator so that the vehicle travels in a normal mode, when it is determined that the forward vehicle is not cruising, and the vehicle follows the forward vehicle in a cruise mode with a fuel economy performance or quietness higher than in the normal mode, when the forward vehicle is cruising.

Abstract: A method of controlling inertial driving of a vehicle is provided. The method includes, when in an inertial driving guidance mode, obtaining information related to at least one event in consideration of a vehicle ahead situation, wherein the at least one event is a stop event, a deceleration event, or a re-acceleration event, determining a target shift stage corresponding to the at least one event based on the information related to the at least one event, and performing a shift control to the target shift stage.

Abstract: A control device of a vehicle with a stepped automatic transmission has: a gradient acquiring part; a driving force calculating part; a future change estimating part; and a shift control part. The shift control part prohibits change of the gear stage when the speed of change of the speed or acceleration of the vehicle in the future if the maximum driving force applied, is within a reference range of speed of change where the occupants would not notice a change in speed or acceleration, and permits change of the gear stage when the speed of change of the speed or acceleration of the vehicle in the future if the maximum driving force applied, is outside the reference range of speed of change.

Abstract: A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.
