摘要： PURPOSE:To prevent a speed change shock from being generated by quickly increasing oil pressure in a hydraulic servo of a friction engaging element for a down shift, until almost completion of engagement of the friction engaging element for an upshift, and by slowly increasing the oil pressure after completion of the engagement. CONSTITUTION:A step S1 judges whether 5-speed speed change judgment is performed or not while 2 3 speed change is performed, and in the case of performing the 5-speed speed change judgment, a step S2 judges whether 3, 5-speed is already formed or not at a point of time of performing the 5-speed change judgment. In the case of forming the 3, 5-speed, the step is advanced to a step S6, and in the case of not forming the 3, 5-speed, the step is advanced to a step S3. The step S3 judges whether a rotational speed Nc2 reaches a preset value or not by almost completing engagement of the second B2, and oil pressure PB0 is increased by the second low pressure increasing rate in a step S5, in the case of the rotational speed reaching the preset value, and by the first pressure increasing rate in a step S4 in the case of not reaching the preset value.

摘要： PURPOSE:To accurately switch engine torque so as to prevent a speed change shock from being generated by outputting an engine torque switching request signal with a delay of the preset timing after judging a speed change starting and canceling the engine torque switching request signal with the delay of the preset timing after judging the speed change ending. CONSTITUTION:When a speed change is judged to be started, a kind of the speed change and a throttle opening are recognized with a signal from a speed change judging means 71 by an engine torque switching request judging means 72 and referred to an engine torque switching map 73. Next, at a point of time in completion of counting the time read from the engine torque switching map 73 by starting a built-in timer, an engine torque switching request signal is fed to an engine torque switching command means 76. When the speed change is ended, it is detected by a rotational speed signal from a rotational speed sensor to count the preset time by restarting the timer, and when counting is completed, the engine torque switching request signal is canceled.

摘要： PURPOSE:To secure a good shift characteristic irrespective of various variations, when two transmission parts are provided and an up-shift is actualized as a whole by a high-gear shift on one side and a low-gear shift on the other. CONSTITUTION:In the case where a first tramsmission part is set to a high-gear shift and a second transmission part to a low-gear shift, respectively, whereby they are subjected to an up-shift as a whole, when a shift of the second transmission part at the shift end (downward) is judged to be delayed, feedback control is suspended, while it is selected to such a control system a forcibly advancing the shift of the second transmission part. With this constitution, even in the case where the second transmission part will not advance as scheduled, such a possiblity that the shift of the second transmission part might exist after the shift end of the first transmission part is prevented from occurring, so a good shift feeling can be always secured in consequence.

摘要： PROBLEM TO BE SOLVED: To prevent sense of speed change from decreasing, when switching the range by operating a shift lever. SOLUTION: The electric vehicle is provided with a vehicle speed detection means 12, an acceleration opening detection means 13, a range selection means, a shift sensor 14 for detecting the range, an output torque command calculation means 15a for calculating an output torque command from a vehicle speed and an acceleration opening, and an advance direction determining means 16 for determining advance direction. The output torque command value calculation means 15a sets an output command to zero, if the switching of a range where a drive direction is inverted in made, when the absolute value of the vehicle speed is equal to or more than a preset value. If the switching of a range, where the drive direction is inverted, is made when the absolute value of the vehicle speed is equal to or more than the preset value, the output torque command value is set to zero, thus preventing the drive direction of a motor 21 from being inverted.

摘要： PURPOSE:To more properly set the initial oil pressure in a release side, so that a speed change of small shock can be always executed, by learning- correcting the initial oil pressure of a shift in the release side of a magnetic field based on a rotational speed of a rotary member before starting feedback control, after starting the shift in the release side. CONSTITUTION:A central processing unit 104 inputs a signal of a C2 sensor 120 for detecting a drum rotational speed (speed change progress condition of the first transmission part 60) Nc2 of a clutch C2 and a signal of a C0 sensor 121 for detecting a drum rotational speed (speed change progress condition of the second transmission part 40) Nc0 of a clutch C0. Before changing a tilt of Nc0 by feedback control after starting a low gear shift, Nc0s (first rotational speed) is monitored to obtain a difference alphaNc0s between this first rotational speed and a target value Ncos at this time, and a logic for judging and correcting a high/low value of initial duty ratio DS by a level of this difference is added.

摘要： PURPOSE:To eliminate generation of a speed change shock and further to shorten a speed change time by performing the second speed change judgment during the simultaneous speed change of a main and speed sub change units. CONSTITUTION:A means of detecting an engine load changing speed is provided for estimating the next speed change judgment. A speed change output control means judges whether or not the engine load changing speed is a predetermined value or more when performed the first speed change judgment where down/up shift speed changes are performed by main and subspeed change units. In the case that the engine load changing speed is the predetermined value or more, the second speed change judging is on standby without performing the first speed change output by estimating the second speed change judgment performed, and the second speed change output is performed immediately when the second speed change judgment is performed. That is, the second speed change output is performed directly without performing the first speed change output, so that a total speed change time is shortened. In the case that the engine load changing speed is smaller than the predetermined value, the first speed change output is performed after the lapse of preset time from the first speed change judgment.

摘要： PURPOSE:To prevent the shortening of the life of constituting components of a motor and/or the life of cooling oil itself upon high-load running or when the circulating amount of oil is reduced. CONSTITUTION:The title vehicle is provided with a vehicle speed detecting means 12, detecting the speed of a vehicle, an accelerator opening degree detecting means 13, detecting the opening degree of an accelerator, and a motor cooling capacity detecting means, detecting the cooling capacity of a motor 21. An output torque commanding value operating means 15 operates an output torque commanding value from the speed of the vehicle and the opening degree of the accelerator while an output torque limiting means 24 corrects the output torque commanding value based on the cooling capacity of the motor 21. The output torque limiting means 24 reduces the output torque commanding value when the cooling capacity of the motor 21 is deteriorated. Accordingly, if the cooling capacity of the motor 21 is deteriorated when a vehicle is running at a high speed or the circulating amount of oil is reduced, the motor 21 can be prevented from being brought into overheated condition.

摘要： PURPOSE:To perform a speed change to a high speed stage from a low speed stage and also a proper speed change output in accordance with an operation condition of power-on condition or power-off condition. CONSTITUTION:A CPU performs speed change judgment according to a running condition and a speed change output to a hydraulic circuit based on the speed change judgment. The speed change output for performing a speed change to the second speed change stage via the highest speed stage from the first speed change stage, which inevitably uses an exclusive hydraulic circuit for a simultaneous speed change, is set by a speed change setting means. That is, in the case of intending the speed change to the second speed change stage from the first speed change stage, the highest speed stage is once formed to perform the speed change to the second speed change stage from the highest speed stage. When a power-off condition is detected by a power on-off detecting means, the second speed change stage is attained after the highest speed stage is formed, but when a power-on condition is detected, a command of inhibiting running of the highest speed stage is canceled and running in the highest speed stage can be performed. A proper speed change output according to an operation condition can be performed.
