ABSTRACT:
The invention concerns a method for the automatic control of a neutral position and a parking lock of an automatic or automated motor vehicle transmission, such that the neutral position and the parking lock of the transmission provided in order to immobilize the motor vehicle can be engaged as a function of a drive setting selected by the driver of the motor vehicle using a selector device, and as a function of other operating parameters of the vehicle. In addition, the invention concerns a motor vehicle controlled by the method.It is proposed that a N-holding phase in which the transmission is in a friction-force-free neutral position can be activated by way of a separate operating device provided in addition to the selector device, only when the motor vehicle is at least almost at rest and at the same time an ignition circuit that acts upon a drive motor of the motor vehicle is electrically interrupted, and at the same time a drive setting “Neutral” (N) is set by way of a selector device, and so long as the parking lock of the transmission has not yet been engaged.
