A vehicle includes a transmission having a variator and a sub-transmission mechanism, a controller serving as a shift control unit adapted to, as shift of the transmission, shift the sub-transmission mechanism and the variator so that a through speed ratio becomes a target speed ratio, and an engine serving as a torque increasing portion adapted to increase a torque inputted to the transmission in association with the shift of the transmission. The controller has a torque setting unit adapted to make a magnitude of an inclination larger as an increase amount of the engine rotation speed in association with the shift of the transmission is larger.

The disclosure provides a control method, a control device for vehicular automatic transmission, and a recording medium. The control device includes an ON/OFF control solenoid controlling LC to either ON or OFF, and an LC pressure control linear solenoid controlling LC pressure between a released state and a fully engaged state. The control device acquires, when an accelerator pedal opening of a vehicle is on a deceleration side in a fully closed state, a torque converter slip ratio when the ON/OFF control solenoid maintains ON for a predetermined time period and the LC pressure control linear solenoid is controlled such that the LC pressure is OFF, and determines whether or not the second solenoid has a high-pressure fixation failure according to whether or not the slip ratio is within a predetermined range from a slip reference value.

A method for controlling an automatic transmission of a vehicle includes: sensing a speed of the vehicle; sensing an acceleration of the vehicle along three spatial axes; determining that the vehicle is in a jump state associated with the vehicle being off a ground surface, the jump state being defined at least in part by the acceleration of the vehicle along the three spatial axes and the speed of the vehicle; and controlling the transmission according to a jump strategy in response to determining that the vehicle is in the jump state. Other methods for controlling an automatic transmission of a vehicle are also contemplated.

A control device performs upshifting in a state in which an operating point of a rotating electrical machine for outputting requirement-based torque at wheel-based rotational speed falls within an operable range of the rotating electrical machine both before and after shifting a shift speed by the upshifting, and in which before shifting the shift speed, output torque from the rotating electrical machine is less than or equal to determination torque (T1), the wheel-based rotational speed being rotational speed of the rotating electrical machine based on rotational speed (V) of a wheel, the requirement-based torque being output torque from the rotating electrical machine based on required wheel transmission torque, and the determination torque (T1) being torque obtained by subtracting an amount of increased torque (ΔTmg) resulting from torque increase control from maximum torque (Tmax) that can be outputted from the rotating electrical machine at the wheel-based rotational speed.

An extension/contraction mechanism in which an extension/contraction part is able to turn is provided. An extension/contraction mechanism according to one aspect of the present disclosure includes a first drive source connected to a sending/pulling part so as to be able to transmit a drive force, and a second drive source connected to the sending/pulling part and a turning part that rotatably supports the sending/pulling part so as to be able to transmit a drive force via a gear group. When a rotational speed transmitted to the sending/pulling part to rotate the sending/pulling part by the first drive source is equal to a rotational speed transmitted to the sending/pulling part to rotate the sending/pulling part by the second drive source, an extension/contraction part turns via the turning part. When the above rotational speeds are different from each other, the extension/contraction part is extended or contracted.
