Problems solved by technology

This adds complexity and thus cost to the manufacture and operation of the vehicle's shift-by-wire assembly
As a result, in known rotary selector mechanisms, especially of the multistable type with an auto park function, when the auto park function is actuated, the Asynchrony between the electric motor of the rotary actuator and the transmission occurs due to the end of the travel member in the assembly

Embodiment Construction

[0032] By way of example, a shift-by-wire shift actuator for controlling a vehicle transmission, generally indicated by the reference numeral 100 , is shown in the drawings. The actuator 100 may be part of a shift-by-wire transmission device having an automatic park function for automatically driving the vehicle transmission into park when certain conditions are met, as will be described herein below. car shift position.

[0033] Specifically, Figure 1 to Figure 9 The shift-by-wire shift actuator 100 in the example shown in is part of a rotary multi-dial shifter and includes a selector knob 110 , a bezel 115 and a housing 116 . The selection knob 110 is rotatably mounted on a bezel 115 in a housing 116 . Thus, the selector knob 110 is rotatable to select one of a plurality of shift positions, such as Park P, Reverse R, Neutral N, and Drive D, to control the vehicle transmission.

[0034] According to the example shown, the shift-by-wire shift actuator 100 includes a display...

Abstract

A shift-by-wire shift actuator comprising: a selection knob (110) rotatable by a user to select a shift position (P, R, N, D) for controlling a vehicle transmission; and A display device (200), associated with the selection knob (110), for sequentially and dynamically providing the simulated selection knob (110) according to the shift position (P, R, N, D) ) for an optical indication of rotational movement. When the vehicle transmission is automatically driven to the Park shift position (P) under certain conditions such as when a person wants to get out of the vehicle, when the vehicle is turned off, when the driver's door is opened, when the seat belt is unfastened, etc., this is The user notifies the autopark feature.

Description

technical field [0001] The present disclosure relates to shift-by-wire shift actuators, and more particularly, to shift-by-wire shift actuators that include a selector knob that can be rotated by a user to select multiple one of the shift positions. [0002] The present disclosure further relates to a shift-by-wire shift device comprising said shift actuator. Also disclosed herein is a method for notifying a user that a vehicle transmission is being automatically actuated into a park shift position when certain conditions are met. Background technique [0003] Rotatable selector mechanisms for shift-by-wire motor vehicle transmissions comprising rotary actuators are known in the art. The rotary actuator is adapted to be rotated by the driver to select different operational shift positions of the transmission, such as Park P, Reverse R, Neutral N and Drive D. [0004] As the rotary actuator is rotated by the driver, a control signal indicating the desired operating shift p...
