An automatic transmission is arranged in a hybrid driveline employing an EV mode and an HEV mode, and establishes transmission ratio positions by engaging or disengaging frictional elements. A system or method includes: determining, based on a vehicle deceleration and a relationship between a requested transmission ratio position and an actual transmission ratio, whether or not interlocking is occurring, when the automatic transmission is in a state out of transmission shifting, wherein the interlocking is due to erroneous engagement of one of the frictional elements; and inhibiting the determination about interlocking, during a period from start of slip of a first frictional element of the automatic transmission to confirmation of convergence of slip of the first frictional element, in a situation that the first frictional element is slip-engaged for starting the engine in response to a request for mode transition from the EV mode to the HEV mode.

The invention relates to an operating method for an automatic transmission, particularly for an automatic variable-speed transmission and/or dual-clutch transmission, for a motor vehicle. The automatic transmission can be operated in a cost-effective manner, particularly with reduced component wear and increased service life, and/or the driving comfort of the vehicle can be improved such that when lifting of at least one driven vehicle wheel off the roadway during braking is detected by the operating method, then for the length of said braking process, in the event of an incomplete gear change into a gear of the transmission, the engagement of a gear is prevented and/or the beginning of a gear change into a gear of the transmission is prevented.

A method for transmitting a shift signal of an electronic shift system, may include transmitting the shift signal generated at the time of operating a shift operation device, wherein the shift operation device is configured so that one shift stage and one shift signal are matched one to one and transmits shift signals which are each individually separated according to the shift stage.

A gear shift lever biasing apparatus includes a shift lever biased primarily along a first dimension axis using a spring. The shift lever is retained to a backing plate, which may be mounted on a frame. A contact area on the backing plate engages with a bumper that is secured to the frame with a semi-rigid retainer, thereby providing bias to the gated shift lever primarily along a second dimension axis that is primarily orthogonal to the first dimension axis.

A shift device for a vehicle having an automated parking mode is provided that includes a shift body and a display section. The shift body is movable into a variety of shift positions, i.e. D, N, R, and P. The display section displays not only the range of shift positions but can also display an automatic parking mode state (AP) when the shift body is in the park (P) state. The display section does not remain in the park P when the vehicle is driven into a parking place by the automatic parking mode, but instead displays the particular shift position (D, R, or N) the vehicle is in as it is being automatically parked.

A shift device includes a knob that is rotatable to select one of a plurality of gear modes of a transmission of a vehicle and a cam member that engages a portion of the knob in a rotation direction of the knob. The cam member rotates integrally with the knob only when engaged with the portion of the knob. The shift device further includes a drive source that rotates the cam member and a controller. The controller controls the drive source to rotate the knob to an operation position corresponding to a predetermined gear mode if a particular condition is satisfied. The controller decreases a voltage applied to the drive source when the cam member is rotated in at least a pre-engagement section until the cam member engages the portion of the knob from the voltage applied when the cam member is rotated in other sections.
