Embodiment Construction

[0036] exist figure 1 , the effect of the method according to the invention is shown schematically by means of two time axes.

[0037] here, figure 1 The upper view of the figure 1 The views shown in the lower part relate to the same process and the same time period.

[0038] t1 indicates the time point when the parking lock function is required to be activated (corresponding to figure 2 Reference numerals in 1). A vehicle equipped with the control device according to the invention has, for example, a low speed of 3 km / h.

[0039] as in figure 1 As seen in the upper view of , the vehicle is braked b with the aid of the vehicle brakes, in particular the vehicle's service brakes, as required at time t1, with as little delay as possible until the time when the vehicle comes to a standstill or approximately stops t2. In the following stop time s, the activation of the parking lock function should be carried out or terminated as quickly as possible, so that activation of th...

Abstract

A method for controlling a vehicle with an automated shift transmission having a plurality of automatically shiftable driving gears and comprising a first friction clutch on the input side and an output device on the output side , wherein two gears are simultaneously engaged in the parking lock function, namely first and second gear, wherein at least at the first speed of the vehicle according to the requirement (1) for activation of the parking lock function In the range (10), the vehicle brakes (11) are activated in order to bring the vehicle to a stop (3), wherein during braking of the vehicle by means of the vehicle brakes, the first gear (12) is engaged and the vehicle At or near a stop (3), engaging said second gear (7) such that said parking lock function is activated, and a vehicle comprising a control device for carrying out such a method.

Description

technical field [0001] The invention relates to a method for controlling a vehicle with an automated shift transmission and a vehicle comprising a control device for carrying out such a method. Background technique [0002] Vehicles with an automated shift transmission are known per se, which have a plurality of automatically shiftable drive gears and which comprise a first friction clutch on the input side and an output device on the output side. Automated shift transmissions have automated shifting components so that the driver does not have to change gears on the shift transmission himself, but usually with the aid of a control program and components such as electric servomotors or hydraulically operated cylinders. [0003] Also known is an automated shift transmission in the form of a dual-clutch transmission, which has a first sub-transmission with a first input shaft having a first set of drive gears and connected on the input side to the first friction clutch; and a ...
