A method for the automatic actuation of a service brake of a motor vehicle in the course of a gear change

摘要

The invention relates to a method for the automatic actuation of a service brake of a motor vehicle in the course of a gear change, which, in a motor vehicle transmission is carried out under interruption. In this case, a braking torque to be displayed by means of the service brake (t_Brake) in accordance with a in the course of the gear change and the associated interruption in tractive force occurring change of a drive rod of the braking torque (δt_{Brake, antr}) set (s9). In a determination of the drive strand brake torque (t_{Brake, antr.}) in this case is an engine braking torque (t_{Brake, mot}) (s4) included by a prime mover, which is connected upstream of the motor vehicle transmission is applied in the overrun mode. In order for the application of the method in the region of a motor vehicle, which are designed as a commercial vehicle is to render in the determination of the drive strand brake torque (t_{Brake, antr.}) in addition, at least one further braking torque (t_{Brake, a.}) included (s4), which in each case by a braking device connected upstream of the motor vehicle transmission is applied.
