摘要： PROBLEM TO BE SOLVED: To provide a control device of a belt type continuously variable transmission for a vehicle, capable of returning a belt to an optimal belt position, without causing belt sliding, even when the vehicle is started from a state of causing belt return failure.SOLUTION: Since feedforward control and feedback control of primary pressure Pin and secondary pressure Pout are performed so that the actual gear ratio γ becomes the belt returning target gear ratio γt, the actual gear ratio γ is shifted to the maximum gear ratio γmax, that is, when returning a belt position of a transmission belt 18 to a position corresponding to the maximum gear ratio γmax, the occurrence of the belt sliding of the transmission belt 18 since the primary pressure Pin is excessively released when the feedback control excessively operates, can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a transmission, capable of restraining unintended deceleration contradictory to a request of a driver from being generated in accompaniment to shift-down by a jumping shift change. SOLUTION: This electronic controller 100 conducts the jumping shift change for switching a shifting position by one shifting position switching operation, up to the shifting position selected when the shift lever 81 or a steering shift switch 91 is continuously operated a plurality of times.

摘要： PROBLEM TO BE SOLVED: To provide an automatic transmission control device for improving drivability while suppressing shock on a vehicle or worse startability of the vehicle in starting the vehicle by actualizing smooth engagement of an engaging element while preventing a rising delay of the engaging pressure of the engaging element even when viscosity is high because the temperature of operating oil is low during restoring an automatic transmission from a neutral condition into a driven condition. SOLUTION: A transmission ECU determines whether execution starting conditions for neutral control are established or not (Step S11) and measures the temperature of operating oil if determining that the execution starting conditions are established (Step S12). The transmission ECU sets the target speed ratio of a torque converter corresponding to the measured temperature of the operating oil (Step S13) and executes neutral control so that the speed ratio of the torque converter corresponds to the target speed ratio (Step S14).
