A method for resetting a parking lock operating system for a motor vehicle includes providing the parking lock operating system and switching the parking lock operating system. The parking lock operating system includes a hydraulic fluid supply line with a hydraulic fluid, a base position in which a parking lock is active, and a transport position in which the parking lock is active. The parking lock operating system is switched from the base position to the base position or from the transport position to the base position by, in the following order: increasing a pressure of the hydraulic fluid above a second pressure threshold, lowering the pressure below a first pressure threshold, less than the second pressure threshold, increasing the pressure above the second pressure threshold, and lowering the pressure of the hydraulic fluid below the first pressure threshold.
A method for resetting a parking lock operating system for a motor vehicle, the parking lock operating system comprising a base position in which a parking lock of the parking lock operating system is active and a transport position in which the parking lock is active, wherein the parking lock operating system is switched both from the base position and from the transport position to the base position when a pressure present in a hydraulic fluid supply line of the parking lock operating system is successively increased twice above a second pressure threshold and is lowered after each pressure increase above the second pressure threshold below a first pressure threshold, which is at a lower pressure value than the second pressure threshold.
A parking lock operating system for a motor vehicle, comprising a guide link and a latching element that can be twisted and axially displaced relative to the guide link, wherein a location of the latching element relative to the guide link defines different positions of the parking lock operating system, wherein the latching element and the guide link have corresponding sloping surfaces which are coordinated and interact with each other in such a way that the latching element is twisted in response to an axial displacement of the latching element along the corresponding sloping surfaces relative to the guide link, the axial displacement being caused by a pressure present in a hydraulic fluid supply line of the parking lock operating system, wherein the corresponding sloping surfaces are arranged such that the parking lock operating system both from a base position, in which a parking lock of the parking lock operating system is active, as well as from a transport position, in which the parking lock is active, is switched to the base position when the pressure present in the hydraulic fluid supply line is increased twice in succession over a second pressure threshold and is lowered after each pressure increase above the second pressure threshold below a first pressure threshold, which is at a lower pressure value than the second pressure threshold.
