20090024286 | METHOD FOR AUTOMATICALLY ENGAGING A PARKING LOCK OF AN AUTOMATIC OR AUTOMATED TRANSMISSION OF A MOTOR VEHICLE - 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 embodiments of a Auto-P function are proposed for automatically engaging the parking lock: two of these embodiments are associated with an electrically interrupted ignition circuit of the motor vehicle; two embodiments are associated with an electrically closed ignition circuit and a simultaneously stopped vehicle drive motor and one embodiment is associated with an electrically closed ignition circuit and a simultaneously operating drive motor. | 01-22-2009 |
20090111647 | METHOD FOR SELECTING A NEUTRAL POSITION OF A MOTOR VEHICLE TRANSMISSION AND FOR SELECTING A PARKING GEAR OF A MOTOR VEHICLE - The invention relates to a method to select a neutral position of an automatic or automated motor vehicle transmission and to select a parking gear provided to immobilize a motor vehicle, wherein the neutral position and parking device can be set or activated, depending on a gear selected by the driver of the motor vehicle on a selector device and depending on other operating parameters of the motor vehicle. In addition, the invention relates to a motor vehicle controlled by this method. | 04-30-2009 |
20090111648 | METHOD FOR AUTOMATICALLY CONTROLLING A NEUTRAL POSITION AND A PARKING LOCK OF A MOTOR VEHICLE TRANSMISSION - 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. | 04-30-2009 |
20090111649 | METHOD FOR SELECTING A NEUTRAL POSITION OF A MOTOR VEHICLE TRANSMISSION AND FOR SELECTING A PARKING DEVICE OF THE MOTOR VEHICLE - A method for selecting a neutral position of an automatic or automated motor vehicle transmission and for selecting a parking device of the motor vehicle intended for immobilizing the motor vehicle, wherein the neutral position and the parking device can be engaged or actuated as a function of a position chosen by the driver of the motor vehicle on a selector device and as a function of other operating parameters of the motor vehicle. The invention further relates to a motor vehicle controlled by this method. | 04-30-2009 |
20090111654 | METHOD FOR THE AUTOMATIC CONTROL OF A NEUTRAL POSITION AND A PARKING LOCK OF A MOTOR VEHICLE TRANSMISSION - 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. | 04-30-2009 |
20100197456 | METHOD FOR ACTUATING A GEAR STEP IN AN AUTOMATIC OR AUTOMATED TRANSMISSION OF A MOTOR VEHICLE AND CORRESPONDING MOTOR VEHICLE - 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. | 08-05-2010 |
20100326148 | METHOD FOR AUTOMATICALLY ENGAGING A PARKING LOCK OF AN AUTOMATIC OR AUTOMATED GEARBOX OF A MOTOR VEHICLE - 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. | 12-30-2010 |
20110087386 | METHOD FOR ACTUATING THE NEUTRAL POSITION IN AN AUTOMATIC OR AUTOMATED TRANSMISSION OF A MOTOR VEHICLE, AND CORRESPONDING MOTOR VEHICLE - 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. | 04-14-2011 |
20110306465 | METHOD FOR AUTOMATICALLY ENGAGING A PARKING LOCK OF AN AUTOMATIC OR AUTOMATED GEARBOX OF A MOTOR VEHICLE - 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. | 12-15-2011 |
