ABSTRACT:
A method of selecting a neutral position of an automatic or automated transmission and a parking gear to immobilize a motor vehicle. The neutral position and parking device can be set or activated, depending on a gear selected by the driver with a selector device and depending on other vehicle operating parameters. Only when the motor vehicle is at least substantially stationary, an ignition circuit acting on the drive motor vehicle is electrically interrupted and a “Neutral” (N) gear is selected by a selector device occur simultaneously, can an N-holding phase, in which the transmission is in a friction-free neutral position, be activated by a separate control device provided in addition to the selector device, as long as an energy management system of the motor vehicle allows activation of the N-holding phase.
