摘要： Disclosed is a method of diagnosing a malfunction in a dual clutch transmission (DCT) attributable to a gear synchromesh failure, without an output shaft speed sensor. The method includes: calculating, a difference (referred to as a first difference) between a first input shaft speed and the product of a wheel speed and a first gear ratio; a difference (referred to as a second difference) between a second input shaft speed and the product of a wheel speed and a second gear ratio; diagnosing a first input shaft as having a transmission gear synchromesh failure when the first difference is greater than a first reference value and the second difference is equal to or smaller than a second reference value; and performing control such that a gear shifting operation is performed using only a second input shaft when the first input shaft is diagnosed as having a transmission gear synchromesh failure.

摘要： A gear engagement method for a hybrid vehicle includes detecting whether or not baulking occurs when a controller attempts to engage a target gear via a synchronizer. The gear engagement method also includes checking, by the controller, for a stationary state of the vehicle if the result of the detecting shows that there is baulking. The gear engagement method also includes engaging, by the controller via the synchronizer, a different gear that shares a same input shaft with the target gear if the result of the checking shows that the vehicle is in a stationary state. The gear engagement method also includes reattempting an engagement with the target gear after disengaging the different gear. The disengaging and the reattempting are performed by the controller via the synchronizer after the engaging.

摘要： Even when a motor fails in an EV travel mode in which a clutch is disengaged, an amount of hydraulic oil that is supplied to the clutch can be secured by reducing a transmission leaked amount. Accordingly, the clutch can be engaged, and an oil pump can be driven by power of an engine. Thus, an evacuation travel by the engine is allowed when the motor fails in the EV travel mode.

摘要： A vehicle includes a transmission, and an Electronic Transmission Range Selection (ETRS) system. The transmission has a plurality of clutches, a park pawl, and a park sensor. The ETRS system has a controller and an electronic range selector device. The controller is programmed to detect a delay in pull out of the park pawl from a park position and to control an action of the vehicle in response to the delay by receiving an electronic range request signal to shift from a park operating range to another operating range; receiving a park pawl position signal from the park sensor; determining if pull out of the park pawl from the park position has not occurred by a predetermined time; and increasing one of a line pressure, a clutch pressure, and an idle speed if pull out of the park pawl from the park position has not occurred by the predetermined time.

摘要： An electronic control unit that is used in an automatic transmission to regulate oil circulation. The electronic control unit includes a switcher that supplies an electric current to a linear solenoid, a current detector that detects an actual electric current value of the solenoid, a target current calculator that calculates a target electric current value, a feedback controller that sets a duty ratio to match the actual electric current value to the target electric current value and to generate a Pulse Width Modulation (PWM) signal having the set duty ratio, and a corrector that determines whether a coupled oscillation has occurred by obtaining oil pressure information of the hydraulic circuit and to correct the PWM signal when determining that the vibration has occurred.

摘要： The present subject matter provides a method for operating an automatic transmission in a limp mode. The method includes actuating a first non-positive shifting element to an engaged configuration and actuating a second non-positive shifting element to the engaged configuration. A positive shifting element is substantially synchronized after actuating the second non-positive shifting element. The method also includes commanding the positive shifting element to actuate from a disengaged configuration to the engaged configuration.
