摘要： A continuously variable transmission 100 includes a target value setting section 140 which sets a control target value for a control by a control device 107. In the target value setting section 140, a normal mode 141, a kick down mode 142 set to be in a Low gear range more than in the normal mode 141, and a restriction value 143 given in a throttle fully closed state are provided. The control device 107 controls the continuously variable transmission 100 based upon the kick down mode 142 provided in the target value setting section 140, in response to an operation of a kick down operator 132. The control device 107 controls a gear ratio of the continuously variable transmission 100 not to vary to a Low gear range more than the restriction value 143 provided in the target value setting section 140. According to the continuously variable transmission 100, slippage between the primary sheave 102 and the V-belt 105 can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a kick-down control device that enables favorable kick-down of an automatic transmission during EV-mode without causing large acceleration response delay.SOLUTION: By increasing an accelerator position APO from t1, kick-down is started at t2, the kick-down limits a motor torque tTm which increases as Tmo along with the increase in accelerator position APO, while shifting from a release element (direct clutch D/C) to a tightening element (high and low reverse clutch H&LR/C). In an early stage of shift transmission from t2 to inertia phase start t3, the motor torque tTm is limited so as not to exceed a torque upper limit value Tlimit (=Tmo2-Tip) for inertia phase progress from the maximum motor torque Tmo2 that can be output at a motor rotation number Nmo2 of the inertia phase end time t4, thereby limiting the motor torque tTm during the inertia phase (t3-t4).

摘要： PROBLEM TO BE SOLVED: To provide the driving force control device of a vehicle which can perform automatic shift which accords with a driver's intention without the sense of incongruity as necessary, while keeping a gear ratio selected by the driver to a prescribed ratio in a manual shift mode.SOLUTION: When a primary rotation number Np is a kick-down allowable rotation number Nth or less, and an accelerator pedal depressing amount θacc is the kick-down allowable depressing amount θaccth or more, a T/M_ECU20 determines acceleration intention from an accelerator operation of the driver and kicks down the gear ratio to the lower gear ratio side even upon selection of the manual shift mode. In such a case, the kick-down allowable rotation numbers Nth are made different for each mode M of driving force characteristics and on the basis of the primary rotation number Np, a rotation number region in which automatic execution of the kick-down operation is allowed is set to the area which becomes narrower as responsibility for the accelerator operation has a higher mode M.

摘要： A shift control method for automatic transmissions includes the steps of outputting a duty control signal for upshifting to a N+1 speed when an N+1 upshifting signal is input during driving in an N speed, pre-estimating a stroke gap of a friction element for the N+1 speed, determining if an N speed kickdown signal is input or not, outputting a duty signal for downshifting to the N speed when the N speed kickdown signal is input. The step of preestimating a stroke gap includes the step of calculating an amount of hydraulic fluid accumulated on a side of the friction element. The step of calculating comprises the steps of calculating an amount of hydraulic fluid with respect to a duty ratio and integrating the calculated amount of hydraulic fluid.

摘要： PROBLEM TO BE SOLVED: To provide a shift controller and a shift control method for a continuously variable transmission for ensuring synchronism of rotational speed of an engine and vehicle speed even if accelerator pedal step-on incremental operation is performed during re-acceleration by kick-down operation. SOLUTION: This shift controller is provided with a kick-down acceleration control means 110 for setting a kick-down target gear ratio to increase input rotational speed and output rotational speed substantially linearly and controlling the gear ratio based on it when determining kick-down acceleration. When a slow change occurs in the amount of accelerator operation during gear ratio control by the kick-down acceleration control means 110, the amount of compensation accelerator operation giving a limit to a change rate of the amount of accelerator operation is calculated by a compensation part 103 and the kick-down target gear ratio is set based on it to control the gear ratio.

摘要： The upshift and downshift timing of an automatic transmission (5) is set with a predetermined hysteresis in response to the vehicle speed and the depression amount of the accelerator pedal (25). When the accelerator pedal (25) is depressed in a hysteresis region before a downshift, the output torque of the automatic transmission (5) is saturated before the depression amount takes a maximum value. As a result, even when depressing the accelerator pedal (25) further, increases do not result in the output torque of the automatic transmission (5). When the depression amount is less than a predetermined value, this invention sets the rate of increase in the target output torque of the automatic transmission (5) to a value which is smaller than the rate of increase when the depression amount is greater than the predetermined value. Thus saturation of the output torque of the automatic transmission (5) can be prevented by controlling the engine output based on the target output torque determined in this manner while the rate of increase in the drive force when the accelerator pedal (25) is deeply depressed can be maintained.

摘要： PROBLEM TO BE SOLVED: To enable the efficient travelling by preventing the generation of unnecessary shift-down or a delay of shift-up with the structure that a driver finds out a point when a gear change map is switched with the operation of an accelerator pedal by the driver. SOLUTION: A damper 26 gives a change point of the operating force on the way of an operation stroke of the accelerator pedal 8, and starting of shift-up or shift-down by a gear change map, which is provided with a change point of the engine speed on the boundary at the operation quantity of the accelerator corresponding to the change point of the operating force of the accelerator pedal 8, is controlled by operation of the accelerator pedal 8, exceeding the change point of the operating force. The driver can find out the point of switching the change gear map with the operation of the accelerator pedal 8, and the generation of unnecessary shift-down or a delay of shift-up is prevented to enable the efficient travelling. Economical travelling is thereby realized. COPYRIGHT: (C)2005,JPO&NCIPI
