摘要： A shift control device to be applied to a vehicle provided with an automatic transmission includes a detector and a shift mode control processor. The detector detects that the vehicle has passed through a tollgate through which the vehicle is able to pass without stopping. The shift mode control processor switches a shift mode of the vehicle from a first shift mode to a second shift mode the shift mode of the vehicle upon passing through the tollgate is the first shift mode and a predetermined condition regarding one or both of a speed of the vehicle and an accelerator opening degree of the vehicle is satisfied after the vehicle passes through the tollgate. In the first shift mode, a shift operation is performable by a driver, and in the second shift mode, a shift operation is performable by the automatic transmission.

摘要： A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion. The body portion is adapted to be removably coupled to the support member. The securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of said retaining bracket.

摘要： When a control device allows a shift speed formed by a transmission to transition from a pre-shift shift speed to a post-shift shift speed by performing engagement of an engagement-side engagement device and disengagement of a disengagement-side engagement device, the control device allows a torque phase in which a torque-sharing ratio between the engagement-side engagement device and the disengagement-side engagement device changes to proceed by performing engagement control in which transmission torque of the engagement-side engagement device is allowed to gradually increase. During proceeding of the torque phase, the control device controls output torque of a rotating electrical machine such that a rotational speed of an input member approaches a target rotational speed determined based on a pre-shift synchronous rotational speed.

摘要： A working vehicle of this invention includes a main speed change structure that includes a continuously variable speed change structure such as an HMT structure and a multi-speed speed change structure capable of switching between a first power transmission state with a first gear ratio and a second power transmission state with a second gear ratio providing a higher speed than the first gear ratio. A control device causes the continuously variable speed change structure to be accelerated to a forward travel side in accordance with an accelerating operation of a speed change operation member in a forward travel direction, and causes the multi-speed speed change structure to be changed from a first power transmission state to a second power transmission state when the rotational speed of the speed change output shaft reaches a switching speed set to exceed a work speed range.

摘要： A vehicle control device comprising: a balance gradient calculation unit configured to calculate a balance gradient that is a gradient at which a propulsive force of the vehicle and a resistance force applied to the vehicle are balanced when the vehicle travels in a gear-in coasting state in which an engine is connected to a gear and the vehicle travels without supplying fuel to the engine, in a case where a traveling state of the vehicle is a neutral coasting state; and a traveling control unit configured to: switch, based on the calculated balance gradient and a specified road gradient, the traveling state of the vehicle from the neutral coasting state to the gear-in coasting state in a case where the traveling state of the vehicle is the neutral coasting state; and end, the gear-in coasting state when determining that an end condition is satisfied.

摘要： A vehicle control apparatus for controlling a control-subject component provided in a vehicle, by using a learning value of a control parameter which is obtained by a learning operation. The control apparatus includes an obtaining portion for obtaining information related to converged values of learning values of control parameters in a plurality of vehicles provided with respective control-subject components which are the same in type as the control-subject component provided in the vehicle, and a variation determination portion for determining whether a degree of variation among the converged values in the respective vehicles is smaller than a threshold value. The vehicle control apparatus causes the learning value to be converged by a smaller number of times of execution of the learning operation when the degree of the variation is smaller than the threshold value, than when the degree of the variation is not smaller than the threshold value.

摘要： A method for operating a multispeed transmission in a motor vehicle, provided with planetary gearings which can be switched with four switching elements to different gear ratios, and which can be connected by input elements and output elements to a driven input shaft and to an output shaft. The reaction elements can be coupled or locked with a brake, wherein the four planetary gearings can be switched by two brakes and by three shifting clutches to eight forward gear ratios. In the higher gear ratios, at least one first shifting clutch is connected to produce a force flow in the transmission, and in the lower gear ratios, at least a second shifting clutch is connected to produce a force flow in the transmission.

摘要： An automatic transmission for a vehicle drivetrain includes a transmission housing, an input shaft, an output shaft, and a plurality of gears within the transmission housing. The plurality of gears defines multiple mechanical gear ratios between the input shaft and the output shaft. The transmission further includes a plurality of clutches operable to selectively engage the multiple mechanical gear ratios, and a plurality of rotational speed sensors. Each rotational speed sensor is operable to measure rotational speeds relative to the transmission housing for of one of the input shaft, the output shaft, or one of the plurality of gears. The transmission further includes a transmission control system configured to receive signals representing the measured rotational speeds from the plurality of rotational speed sensors and control the plurality of clutches to change between gear ratios based at least in part on the signals representing the measured rotational speeds.
