Patent ID: 8062180

Claim:
A method for automatically engaging a parking lock of one of an automatic or an automated gearbox of a motor vehicle that can be engaged depending on a drive position (P, R, N, D) selected by a driver of the motor vehicle by way of a selector device, and depending on other operating parameters of the motor vehicle, the method comprising the steps of: one of retaining engagement of or automatically engaging a drive position of “Neutral” (N) in the gearbox, IF a detected current speed (v_Fzg) of the motor vehicle is lower than a predefined low threshold value, AND simultaneously both an ignition circuit of the motor vehicle that acts on a drive motor of the motor vehicle is electrically interrupted, AND a drive position of “Neutral” (N) is selected by way of the selector device; AND automatically engaging the parking lock of the gearbox, IF the current speed (v_Fzg) of the motor vehicle is lower than the predefined low threshold value, AND simultaneously both the ignition circuit is electrically interrupted, AND a one of drive position of “Drive” (D) or “Reverse” (R) is selected; AND one of retaining engagement of or automatically engaging the parking lock of the gearbox, IF the current speed (v_Fzg) of the motor vehicle is lower than the predefined low threshold value, AND simultaneously both the ignition circuit is electrically interrupted, AND a drive position of “Park” (P) is selected by way of the selector device.
