发明名称 METHOD FOR ACTUATING A GEAR STEP IN AN AUTOMATIC OR AUTOMATED TRANSMISSION OF A MOTOR VEHICLE AND CORRESPONDING MOTOR VEHICLE
摘要 <p>A method of actuating a gear step in an automatic or automated transmission of a motor vehicle. The gear step of the transmission and a parking lock, which immobilizes the vehicle, can be engaged as a function of a gear step (P, R, N, D) that can be selected by the driver via a controllable selector device, and as a function of other motor vehicle operating parameters. A separate operating device, which is in addition to the selector device, can activate a holding phase, in which the transmission is in a traction-free neutral position, independently of a predetermined gear step“Park”(P),“Reverse”(R),“Neutral”(N) and/or“Forward”(D) that is specified by the selector device, if the motor vehicle is at least almost at a standstill and at the same time, an ignition circuit acting on a drive motor of the motor vehicle is electrically interrupted.</p>
