Provided are a variator and a transmission controller in an engine-driven vehicle. The transmission controller has an instantaneous interruption recovery control portion configured to, upon a power reset from an instantaneous interruption during running, set a target through transmission ratio and a desired through transmission ratio to a lowest transmission ratio value by initialization and perform recovery control to recover an actual through transmission ratio of the variator to a transmission ratio value for shifting to normal control. The instantaneous interruption recovery control portion is further configured to, upon the power reset from the instantaneous interruption during the running, set a change speed of the target through transmission ratio from the lowest transmission ratio value to the desired through transmission ratio, to be higher than that under the normal control, before a time at which the desired through transmission ratio value deviates from the lowest transmission ratio value.

A jamming protection apparatus of a shift lever for a vehicle includes a shift lever rotatably provided in a housing. A contact portion is provided in the shift lever and is provided with an elastically behaving bullet. A detent portion is disposed such that the bullet of the contact portion is brought in contact with the detent portion in the housing. The detent portion is moveably seated in the housing and is provided with a grooved bottom configured such that the bullet moves over the grooved bottom when the shift lever is rotated. A behavior generator is connected to the detent portion and is configured such that the detent portion is moved by an operation of the behavior generator.

The present invention addresses the problem of obtaining an electronic control device for a vehicular automatic transmission that suppresses sudden acceleration, sudden deceleration, and gear shift shock that occur when the transmission moves into a fail-safe mode due to the electronic control device stopping during a main CPU abnormality. An electronic control device 100 for a vehicular automatic transmission has: a main CPU 3 that performs gear shift control for the vehicular automatic transmission; and a sub-CPU 4 that detects abnormalities in the main CPU 3. When the sub-CPU 4 detects an abnormality in the main CPU 3 while the vehicle is traveling, the sub-CPU 4 stops the gear shift control executed by the main CPU 3.

An apparatus for fixing a sticking damper clutch may include: a transmission controller configured to determine whether a damper clutch sticks, using engine controller information received from an engine controller and damper clutch status information of the damper clutch; and a hydraulic pressure controller configured to fix the sticking damper clutch according to the determination result of the transmission controller.

Disclosed herein is a gear actuator for a double clutch transmission, which includes a power module (100), including odd and even-numbered stage select solenoids and shift motors, a controller directly connected to them, and select levers connected to select rods of the select solenoids, shift modules (200) for transmitting the rotational forces of the shift motors to a control shaft assembly (300), the control shaft assembly (300) for transmitting the operating force of the power module (100) to a shift lug, and a body housing (400) having the power module (100), the shift modules (200), and the control shaft assembly (300) installed therein. Accordingly, the gear actuator can have a more compact structure and be easily assembled by modularization.
