摘要： In a vehicle provided with a continuously variable transmission, when a target speed change ratio sharply decreases due to the release of an accelerator pedal from depression, a real speed change ratio of the continuously variable transmission which follows the target speed change ratio may undershoot the target speed change ratio. Due to this undershoot, the engine rotation speed may temporarily fall below a permitted level. Therefore, the variation rate of the speed change ratio of the transmission is decreased in the terminal phase of the shifting process of the speed change ratio.

摘要： A speed ratio controller for a continuously variable transmission of a vehicle is provided which sets a target speed ratio according to a vehicle speed and degree of accelerator pedal depression, sets a command speed ratio according to the target speed ratio and a predetermined dynamic characteristic, and controls the transmission so as to obtain the target speed ratio while a real speed ratio follows the command speed ratio. This speed ratio controller computes a deviation between the command speed ratio and target speed ratio, and determines whether an upshift characteristic is an auto upshift, foot release upshift or foot return upshift based on the speed ratio deviation, degree of accelerator pedal depression, and variation amount of the target input shaft rotation speed. The dynamic characteristic of the command speed ratio is set according to the determination result, and the response characteristics of the transmission are thereby modified.

摘要： A continuously variable transmission 4 for a vehicle includes a variator 20 that modifies a speed ratio continuously and a subtransmission mechanism 30 that is connected in series to the variator 20 and applies a first speed and a second speed, which is higher than the first speed, selectively. When the vehicle is running under a low load/high speed upshift condition having a lower load or a higher speed than a normal upshift condition, the subtransmission mechanism 30 is upshifted from the first speed to the second speed at a lower vehicle speed than under the normal upshift condition, and as a result, both rotation variation in an internal combustion engine 1 accompanying upshifting of the subtransmission mechanism 30 and an increase in a fuel consumption amount of the internal combustion engine 1 due to the shift operation in the continuously variable transmission 4 are suppressed.

摘要： A speed change control device for an automatic transmission according to this invention determines whether or not a request to downshift a gear position of the transmission exists during traveling in a manual speed change mode (S1, S2), and calculates an input shaft rotation speed of the transmission following a downshift based on the downshift request (S4). When it is determined that the calculated rotation speed is higher than a rotation speed limit value (S5), the speed change control device performs a downshift to a gear position at which the input shaft rotation speed of the transmission is lower than the calculated rotation speed (S6, S8).

摘要： A vehicle engine (70) is connected with a belt-type continuously variable transmission (1) via a clutch (32). The transmission (1) transmits torque via a belt (43) between a pair of pulleys (41, 42), and varies the transmission torque according to a supply of oil pressure. The clutch (32) engages by means of oil pressure supplied as a shift lever is changed over from a neutral range to a drive range. An oil pressure supplying device (10, 44, 45, 46) supplies the oil pressure required to transmit torque between the belt (43) and the pulleys (41, 42), and the oil pressure for engaging the clutch (32). Slippage between the belt (43) and the pulleys (41, 42) is prevented during engagement of the clutch (32) by restricting the output torque of the engine (70) over a predetermined period of time.

摘要： A shift control apparatus outputs a command transmission ratio to a continuously variable transmission (CVT) to control a real transmission ratio of the CVT. The shift control apparatus comprises a shift mode determining section determines whether an actually selected shift mode is an automatic upshift or a power-down upshift (foot-release upshift), on the basis of the result of a previously selected shift mode, a difference between a final objective transmission ratio and a transient objective transmission ratio and a rate of change in the transmission ratio per time. The dynamic characteristic selecting section determines the dynamic characteristic according to the determined shift mode.
