摘要： An automatic transmission control system provided with a speed sensor for monitoring an input speed to the automatic transmission, on one hand, prohibits gear shifts only to gears which are provided by alternately locking and unlocking two friction coupling elements at a timing determined essentially based on an input speed when an failure of the speed sensor occurs and, on the other hand, permits gear shifts to gears which are provided in participation of the one-way clutch by alternately locking and unlocking the two friction coupling elements, a timely alternate lock and unlock operation of the two friction coupling elements being spontaneously caused by the unlock operation of one of the two friction coupling elements and gear shifts to gears which are provided by locking one of the two friction coupling elements and unlocking the other with common pressure or unlocking one of the two friction coupling elements and locking the other with common pressure.

摘要： The invention relates to a method for selecting a gear position of an automatic vehicle transmission with at least one forward gear position and a reverse gear position, in the case of which, at defined operating conditions, a shifting operation from the forward gear position into the reverse gear position or vice versa is ignored. The object of avoiding faulty operations when operating an automatic transmission and increasing the driving comfort is achieved in that the shifting operation is carried out up to a defined first speed of the vehicle, in that, in a speed range of the vehicle between the first and a second speed, during the shifting operation, only a neutral gear position is engaged, and in that the shifting operation is ignored above the second speed.

摘要： A control device for an automatic transmission which prevents an automatic transmission from executing a “busy-shift” caused by a lower gear ratio of the highest gear, and which reduces revolutions of a driving power source at high speed. The control device includes an automatic shift mode, an independent manual shift mode, and a highest gear control. The automatic shift mode automatically determines a gear ratio of the automatic transmission on the basis of a driving condition of a vehicle having the automatic transmission. The manual shift mode determines a gear ratio of the automatic transmission by a driver's intention. The highest gear control controls the automatic transmission, so that the smallest gear ratio set by the manual shift mode is smaller than the smallest gear ratio set by the automatic shift mode. If the gear ratio of the highest gear of the automatic shift mode is not so small, a shift caused by a change of a driving condition does not easily occur. The busy-shift can be avoided in the automatic transmission.

摘要： In a procedure for controlling gear shifting of a subtransmission which can be carried out only when a vehicle is substantially standing, a vehicle speed pulse is generated, a time is counted from the time each vehicle speed pulse is generated (steps 101, 102). This time is a period for which a first condition by which the vehicle can be considered, regardless of the pulse, to be running is satisfied. At the same time the first condition becomes unsatisfied from a satisfied state, the counted time is determined to be a first condition satisfied period T1, and a waiting period Tw is determined in a predetermined manner by using the first condition satisfied period (step 103). A time T2 is counted from the time the first condition becomes unsatisfied, and when the counted time T2 reaches the determined waiting period, the gear shifting of the subtransmission becomes possible (step 105).

摘要： An electronic transmission control system for an automotive vehicle with a belt-type continuously variable automatic transmission comprises a transmission ratio control device including a first motor-driven oil pump supplying working pressure directly to a secondary pulley actuation chamber, and a second motor-driven oil pump supplying working pressure directly to a primary pulley actuation chamber and enabling working oil to come and go between the primary and secondary pulley actuation chambers therethrough. A first control section is provided for controlling the first motor-driven oil pump with feed-forward compensation for the working pressure supplied to the secondary pulley actuation chamber, based on changes in a flow rate of the working oil coming and going between the primary and secondary pulley actuation chambers, so that the secondary pulley pressure is regulated as a belt capacity holding pressure needed to hold a belt capacity of the drive belt in a first motor-driven pump side. Also provided is a second control section controlling the second motor-driven oil pump, so that the primary pulley pressure is regulated as a belt capacity holding pressure needed to hold a belt capacity of the drive belt in a second motor-driven pump side and so that a required value of a speed-change flow rate of the working oil coming and going between the primary and secondary pulley actuation chambers is obtained.
