A shift device includes: a shift switching member including a plurality of valley portions corresponding to shift positions; a motor that includes a rotor and a stator and that is configured to drive the shift switching member; and a positioning member configured to establish the shift positions in a state in which the positioning member is fitted into any one of the plurality of valley portions of the shift switching member. The shift device is configured to learn the shift positions based on a change amount of a load torque applied to the motor while the positioning member is moved to continuously pass through the plurality of valley portions.

An actuator for activating a plurality of operating functions in a technical system may include one or more of the following: a rotary knob, the rotary knob being rotatable about a rotational axis to an actuation position corresponding to a first operating function of a plurality of operating functions; a first sensor unit, where the actuation position is detectable by the first sensor unit such that a corresponding actuation position signal is sent to a control unit of the technical system causing activation of the first operating function; a second sensor unit for sending a shut-off signal to the control unit, where the technical system is set to a basic function of the plurality of operating functions upon receipt of the shut-off signal; and at least one sliding track partially encircling the rotary knob radially over an angle of less than 360.

A system and method of controlling a shift mechanism for a vehicle, includes a shift determination unit configured to determine information on a shifting stage of the vehicle according to an operation of the shift mechanism; and a control unit configured to receive the information on the shifting stage from the shift determination unit and to transmit a signal such that vibration is generated in the shift mechanism when the shifting stage switched by operation of the shift mechanism is a drivable shifting stage, wherein when a driver operates the shift mechanism to switch a shifting stage to a drivable shifting stage, a signal according to the corresponding shifting stage is transmitted to enable the driver to recognize the switched shifting stage and thus to prevent erroneous operation, ensuring driving safety.

The invention relates to a rotary control device for a vehicle comprising a user interface surface, in particular a knob, that is embodied to rotate with respect to a housing of the device around a rotational axis of the device, further comprising a sensor unit for monitoring the orientation and/or rotational movement of the user interface surface with respect to the housing, a processing unit, and a communications interface for transmitting control signals according to an output from the processing unit, said output being generated by the processing unit on the basis of sensor data from the sensor unit.

A shift control system for an automatic transmission is provided, which is mounted on a vehicle configured to be started by an ignition switch being turned on, where an automatic transmission mode or a manual transmission mode is selectively set. The system includes a shift switch through which a manual transmission command for arbitrarily changing a gear stage of the automatic transmission can be inputted in the manual transmission mode, and a controller. The manual transmission mode includes a first manual mode in which the gear stage is changed and maintained by inputting the manual transmission command using the shift switch, and a second manual mode in which the automatic transmission mode is resumed by satisfying a resuming condition after the gear stage is changed. When the ignition switch is turned on, the controller selects in advance the second mode to be set to the automatic transmission.

A selector lever assembly for selecting and shifting to various driving modes in a vehicle transmission may include a rotary knob that is connected to a shaft element supported in a housing, where the driving modes are assigned to the rotational range of the shaft element, and separated from one another by a latching contour that can be felt by a driver, and where the rotation of the shaft element can be blocked by a locking contour, and where the shaft element is connected to a disk element for conjoint rotation, but can be displaced axially in order to activate and deactivate at least one further function mode.

In a vehicle including a shift-by-wire (SBW) transmission which may be parked in the neutral gear position of the transmission, method for controlling parking thereof includes determining whether the vehicle is in a situation in which neutral parking is required according to sensor information, when the vehicle is stopped, outputting first information configured to get a confirmation on whether a driver intends to perform the neutral parking from the driver, when the controller concludes that the vehicle is in the situation in which the neutral parking is required and when a park (P) gear position is input or an ignition of the vehicle is turned off, and controlling the SBW transmission to shift to a neutral (N) gear position, when there is an agreement input as a response to the first information.

A rotary-type automotive transmission is provided. The rotary-type automotive transmission includes a housing; a shaft coupled to the housing in an axial direction; a bullet part provided on a surface of the shaft to be elastically projected in a first direction, which is perpendicular to the axial direction, and/or in a second direction, which is opposite to the first direction; and a groove part mounted in a receiving groove that is formed on a surface of the housing, to face the bullet part. The groove part slidably moves in the first direction and/or in the second direction to be received in the housing.

An electronic shift control apparatus may include a shift dial that a user operates to select an R-range, an N-range (Nd-range and Nr-range), and a D-range, a P-range button which is operated to select a P-range, and a haptic motor that generates a haptic signal. When a driver shifts into a specific shifting range (R-range) of a vehicle by operating the shift dial, a haptic signal may be transmitted to the driver.

A selector unit includes a protruding portion and a dial member. The dial member is configured to be displaced between an initial position and a depressed position along an axial direction of the protruding portion, and to be rotationally operable in a circumferential direction when depressed to the depressed position. An offset angle at a rearward side when the dial member is at the initial position is greater than the offset angle at a forward side when the dial member is at the depressed position. The offset angle means an angle between an extended line obtained by extending an upper face of the protruding portion outwards in a radial direction and a tangential line in contact with both the upper face of the protruding portion and an upper face of the dial member, in a section including a rotation axis of the dial member.
