Embodiment Construction

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

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

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

[0039] As in figure 1 As can be seen in the upper view of the vehicle, according to the requirements at time t1, the vehicle brakes, especially the service brakes of the vehicle, are used as far as possible without delay to brake the vehicle until the vehicle stops or approximately stops. t2. In the next stop time s, the activation of the parking lock function should be executed or ended as quickly as possible, so that the activation of the parking loc...

Abstract

A method for controlling a vehicle which has an automated manual transmission and a plurality of gears which can be selected in an automated manner and, on the input side, comprises a first friction clutch and, on the output side, comprises an output, wherein two gears are engaged simultaneously in a park lock function, specifically a first gear and a second gear. In response to a request to activate the park lock function (1), a vehicle brake is activated (11) at least in a first speed range (10) of the vehicle in order to bring the vehicle to a standstill (3), the first gear being engaged (12) during braking of the vehicle by means of the vehicle brake and the second gear being engaged (7) when the vehicle (3) is at a standstill or almost at a standstill, such that the park lock functionis activated. The invention also relates to a vehicle comprising a control apparatus 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 including a control device for implementing such a method. Background technique [0002] A vehicle having an automated shift transmission is known per se, which has a plurality of automatically switchable driving gears, and includes a first friction clutch on the input side and an output device on the output side. Automated shift transmissions have automated switching components so that the driver does not need to shift gears on the shift transmission by himself, but usually shifts gears with the help of control programs and components such as electric servo motors or hydraulically operated cylinders. [0003] Also known is an automated shift transmission configured as a dual-clutch transmission, which has: a first sub-transmission with a first input shaft, the first input shaft having a first set of driving gears, and It is connected with the first...
