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

Abstract: There is provided a transmission control device that controls a first prime mover and a second prime mover of which output responsiveness is different from each other. A processing circuitry of the transmission control device executes a process including: in response to a shift command, calculating each target rotational speed of the first prime mover and the second prime mover for a synchronous control that brings one of rotational speeds of a dog and a transmission gear at the second transmission gear position close to the other; and determining a first timing or a second timing such that the second timing is later than the first timing, the first timing being a time at which the synchronous control of the first prime mover is started, and the second timing being a time at which the synchronous control of the second prime mover is started.

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 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.

Abstract: An automatic transmission controller is provided, which is capable of reducing occurrence of a shift shock while improving responsiveness of a driving force. An ECU is configured to calculate a target shift time based on an input torque that is input to the automatic transmission when a gear stage is shifted from a current gear stage to a target gear stage spaced two or more stages apart from the current gear stage. The ECU is also configured to: shift the gear stage to an intermediate gear stage between the current gear stage and the target gear stage when the target shift time is not less than a predetermined value; and to shift the gear stage directly to the target gear stage when the target shift time is less than the predetermined value.

Abstract: Disclosed is a control apparatus for a vehicular transmission comprising: a vehicle speed sensor; an accelerator opening angle sensor; and a gear-shift control section (8D) of a CVTECU 8. The vehicle speed sensor includes: an output shaft rotation speed sensor (90) configured to detect a rotation speed (rotation numbers) of an output shaft (41) of the automatic transmission; road wheel rotation speed sensors configured to detect rotation speeds (rotation numbers) of four road wheels (90B through 90E); and a vehicle speed calculating section (8B) of CVTECU 8 configured to calculate the vehicle speed from the information of the road wheel rotation speeds when a preset predetermined condition as a condition under which vertical variations of the rotation speed of the output shaft are generated is established and calculate the vehicle speed from the output shaft rotation speed information if the predetermined condition is not established.

Abstract: When an engagement-side clutch taking charge of rotation control in an upshift is the same as a rotation control clutch of a previous gear shift, it is determined that there is a likelihood that a thermal load of a clutch friction material will increase, and the thermal load of the clutch friction material is decreased by delaying gear shift start. By setting a delay time by which the gear shift start is delayed when an accelerator depression amount is small to be shorter than when the accelerator depression amount is large depending on the accelerator depression amount, a gear shift which is an upshift can be performed without unnecessary waiting.

Abstract: A control system for a transmission reverser having an output gear, a forward disconnect device, a first reverse disconnect device, and a second reverse disconnect device includes one or more controllers with processing and memory architecture configured to execute control logic to control the transmission reverser in a forward mode and a reverse mode. In the forward mode, the one or more controllers command the first reverse disconnect device to disengage and the forward disconnect device to engage to rotate the output gear in a forward direction. In the reverse mode, the one or more controllers command the first reverse disconnect device to engage and the second reverse disconnect device to engage to rotate the output gear in a reverse direction.

Abstract: An object of the present invention is, even if an abnormality occurs in an oil pressure circuit of an automatic transmission, to avoid a case where a traveling performance deterioration by the abnormality when gear change is performed. The present invention provides a control device of an automatic transmission and a method of controlling the automatic transmission, each of which switches from a normal state to an abnormality diagnosis state at a predetermined change gear ratio to diagnose whether there is an abnormality in an automatic transmission, the normal state being a state where an oil pressure supply portion supplies oil pressure to a predetermined friction engaging element, the abnormality diagnosis state being a state where an abnormality diagnosis oil pressure supply portion including an oil pressure supply passage different from an oil pressure supply passage of the oil pressure supply portion supplies the oil pressure to the predetermined friction engaging element.

Abstract: The present invention is directed toward a shift actuator assembly that includes a housing having a retaining mechanism. A holding pawl is biased into engagement with the retaining mechanism. A solenoid releasably engages the pawl when the shift shaft is disposed in its first position such that once the solenoid disengages the pawl, the cam surfaces on the retaining mechanism cooperate with the holding surfaces on the pawl to drive the pawl out of engagement with the retaining mechanism thereby releasing the biasing force of the biasing mechanism to drive the housing and the shift fork axially on the shift shaft between engaged and disengaged positions with respect to the associated gear set.

Abstract: In a vehicle automatic transmission having structure in which an output-side rotating element is provided between a speed increasing-side rotating element that is connected to an engine via input clutch and increased rotation speed during downshift into a predetermined speed, and a speed reducing-side rotating element that is reduced in rotation speed by a second engagement apparatus being engaged during the downshift, in an alignment graph, the first engagement apparatus is engaged when, or after, the second engagement apparatus is engaged at the time of the downshift into the predetermined speed. As a result, the rotation speed of the speed reducing-side rotating element is reduced first by the engagement of the second engagement apparatus, which causes driving force to act on the output-side rotating element in a direction that reduces the rotating speed thereof. As a result, forward driving force is prevented from being generated by the output-side rotating element.
