Estimating the term…
The methods and devices for actuating a parking brake in a gearbox which is actuated in an automated manner, whereby gear changes are carried out by means of at least one electrically driven actuator, gear positions can be selected by means of a selector device, and the parking brake can be activated by means of the selector device when the vehicle is stationary or moving slowly. The invention also relates to a vehicle provided with an additional gearbox. The ignition key can only be removed, when the gearbox is in the P state and the additional gearbox is not in the N state. The further method and device, whereby the additional gearbox can only be shifted in the N state when the gearbox is not in the P state. The methods and a device for carrying out the same, by automated manual gearboxes, especially parallel gearboxes, are controlled in such a way that the vehicle can be safely parked and can set off in a reliable and comfortable manner.
A method for controlling the removability of an ignition key and for the actuation of a parking lock in a vehicle having an automatically actuated transmission in which gear changes are carried out via at least one actuator and transmission positions are selectable via a selector device, the transmission having a P operating mode that blocks the rotation of an output shaft and having an additional transmission disposed between the transmission and the vehicle wheels that activates the parking lock via the selector device or shifts into an N operating mode, in which its output shaft rotates freely while disengaged from the input shaft, when the vehicle is stationary or moving slowly, in which method the removability of the ignition key is only enabled if the transmission is in the P operating mode and the additional transmission is not in the N operating mode.
