发明名称 Method for actuating the neutral position in an automatic or automated transmission of a motor vehicle, and corresponding motor vehicle
摘要 A method for shifting an automatic or an automated transmission of a motor vehicle to a "neutral" position such that the shift position of the transmission and a parking lock, provided for keeping the motor vehicle stationary, are engaged as a function of a shift position selected with a driver operated selector device and as a function of other operating parameters of the motor vehicle. A holding phase, in which the transmission is in the neutral position, free from friction force locking, can be activated by a separate operating device which is provided, in addition to the selector device, but only when the motor vehicle is simultaneously at least approximately stationary, an ignition current circuit that acts on a drive engine of the motor vehicle is electrically interrupted, and the "neutral" (N) shift position is specified by a selector device.
