  • Patent number: 8128530
    Abstract: A method of automatically controlling a neutral position and parking lock of an motor-vehicle transmission to immobilize the vehicle depending on a drive position of the transmission selected by the driver with a selector device and subject to other operating parameters of the motor vehicle. Only when simultaneously the vehicle is essentially stationary, an ignition circuit is electrically interrupted and the selector device is in a “Neutral” position, can an Neutral-holding phase be activated, in which the transmission is in a non-frictionally engaged neutral position as long as the parking lock of the transmission has not yet been engaged. If the Neutral-holding phase has not been activated, the transmission remains non-frictionally connected in the Neutral position until the driver at least intends to exit the vehicle, at which time the parking lock of the transmission is automatically engaged.

  • Patent number: 8062176
    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.

  • Patent number: 8062177
    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.

  • Patent number: 8016719
    Abstract: A method for selecting a neutral position of a transmission and for selecting a parking device intended for immobilizing a vehicle, wherein the neutral position and the parking device can be engaged or actuated as a function of a position chosen by the driver on a selector device and as a function of other vehicle operating parameters. It is proposed that only if the vehicle has come approximately to a stop and simultaneously an ignition circuit acting on a driving motor of the vehicle is electrically interrupted and simultaneously a “Neutral” position is specified by way of the selector device, an N-holding phase, in which the transmission is in a neutral position having no frictional connection, can be activated by way of a separate control device provided in addition to the selector device, as long as an energy management system of the motor vehicle allows the activation of the N-holding phase.
