  • Publication number: 20190390764
    Abstract: A method may include at least a step for inputting a parking position signal and a step for issuing a braking signal. In the step for inputting a parking position signal, at least one parking position signal is input that represents a movement of a gearshift lever of an automatic shifting device in the vehicle toward a gearshift lever parking position (P) by a driver of the vehicle via at least one intermediate position (Z). In the step for issuing a braking signal, at least one braking signal is issued for executing a braking procedure to reduce the speed of the vehicle using the parking position signal when the speed of the vehicle exceeds a predetermined minimum speed.

  • Patent number: 10502313
    Abstract: A selector lever for a transmission of a vehicle may include a monostable control element. Actuation of the monostable control element, without moving the selector lever, may triggers engagement of a parked position of the transmission when the transmission is not in the parked position and the drive motor is running. Further, actuation of the monostable control element may trigger a start process of the drive motor when the drive motor is off. Further, actuation of the monostable control element may trigger a shutdown process of the drive motor when the transmission is in the parked position and the drive motor is in on.

  • Publication number: 20160280226
    Abstract: The current embodiments provide a selector lever for an automatic or automated manual transmission that is connected to a drive motor of a motor vehicle. The selector lever may be moveable between different positions for engaging positions of the transmission. The selector lever may have at least one monostable control element configured such that actuation of the monostable control element without moving the selector lever triggers engagement of a parked position of the transmission and/or triggers a start process or a shutdown process of the drive motor depending on the engaged position of the transmission and the state of the drive motor.

  • Patent number: 8521378
    Abstract: 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.

  • Patent number: 8235866
    Abstract: 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.

  • Patent number: 8197388
    Abstract: A method of automatically engaging a parking lock or an automatic or automated gearbox of a motor vehicle, which can be engaged depending on a drive position selected by the driver of the motor vehicle, by way of a selector device and depending on other operating parameters. In order to achieve as little restriction of the drivability of the motor vehicle as possible, without neglecting the safety of the driver and surroundings, two different complex embodiments of an Auto_P function for automatically engaging the parking lock are proposed, if the motor vehicle is at least approximately stopped and, at the same time, an ignition circuit acting on the drive motor of the motor vehicle is electrically interrupted.

  • 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: 8121762
    Abstract: A method of automatically engaging a parking lock of an automatic or automated transmission of a motor vehicle, which can be engaged by way of a selector device depending on a drive position selected by the driver of the motor vehicle and depending on other operating parameters. In order to achieve as little restriction of the drivability of the motor vehicle as possible, without neglecting the safety of the driver and the surroundings, five different variation of an Auto-P function are proposed for automatically engaging the parking lock: two of these variations are associated with an electrically interrupted ignition circuit of the motor vehicle; two variations are associated with an electrically closed ignition circuit and a simultaneously stopped vehicle drive motor and one variations is associated with an electrically closed ignition circuit and a simultaneously operating drive motor.

  • 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.
