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 control device for controlling a continuously variable transmission (5) is disclosed. The control device has an oil pressure control unit (100) which supplies an oil pressure to a primary pulley (10) and secondary pulley (11) based on a command signal indicative of a target speed-reduction ratio, a sensor (26) which detects a rotation speed ( Np1 ) of the primary pulley (26), and a controller (20) which transmits the command signal indicative of the target speed-reduction ratio to the oil pressure control unit (100). The controller is programmed to set the target speed-reduction ratio to a first speed-reduction ratio ( R1 ); calculate a first predetermined rotation speed ( N1 ) of the primary pulley at which the V-belt reaches a first limiting temperature ( T1 ) at the first speed-reduction ratio ( R1 ); calculate a first elapsed time after the detected rotation speed ( Np1 ) of the primary pulley exceeds the first predetermined rotation speed ( N1 ); maintain the first speed-reduction ratio ( R1 ) when the first elapsed time is equal to or less than a first predetermined time; and set the target speed-reduction ratio to a second speed-reduction ratio ( R2 ) smaller than the first speed-reduction ratio ( R1 ) when the first elapsed time exceeds the first predetermined time. At the second speed-reduction ratio ( R2 ), the temperature of the V-belt should become equal to or less than the first limiting temperature ( T1 ) throughout the permitted rotation speed region of the primary pulley. Thus, starting acceleration performance of the continuously variable transmission is enhanced.

摘要： A controller (50) controls the supply of oil pressure to a primary pulley (41) and a secondary pulley (42) of a belt-drive continuously variable transmission (1) in accordance with the depression amount of an accelerator pedal (81) of a vehicle. When slippage is detected in a V-belt (43) that is wrapped around the primary pulley (41) and secondary pulley (42), the controller (50) reduces the output torque of an engine (70) of the vehicle to stop the V-belt (43) from slipping. Meanwhile, damage to the V-belt (43) caused by slippage is prevented by reducing the oil pressure supply to the secondary pulley (42).

摘要： Disclosed are a control system and a control method for an automatic transmission, in which a judgment is made whether or not a range selector (31) has been switched to a reverse range during forward traveling of the vehicle. When it is determined that the range selector (31) has been switched to the reverse range during forward traveling of the vehicle, a judgment is made whether or not the vehicle speed is lower than a first vehicle speed and whether or not the period of time that has elapsed until switching from the forward to the reverse range is shorter than a predetermined judgment time. When the vehicle speed is lower than the first vehicle speed and the period of time that has elapsed until switching from the forward to the reverse range is shorter than the predetermined judgment time, a forward/backward changeover mechanism (4) is switched to a reverse mode. Otherwise, the switching of the forward/backward changeover mechanism (4) to the reverse mode is delayed.
