Abstract:
1. A method of controlling a drivetrain of a motor vehicle in which the drivetrain comprises a drive motor, an automated manual transmission with a plurality of starting gears and an automated clutch arranged in a force flow between the drive motor and the transmission, and a manual shift lever being movable in an upshift direction, to bring about an upshift, and in a downshift direction, to bring about a downshift, and the transmission together with the clutch are controlled by a transmission control unit connected to at least a speed sensor, an accelerator pedal actuation sensor and a manual shift lever actuation sensor such that, when starting off from a vehicle rolling condition, a starting gear is determined in a manner that is influenced by a driver via actuating the manual shift lever, if a speed of the vehicle (V F ) is within a specified coasting speed range, it is checked whether the transmission is shifted to neutral (G i =N) and the clutch is engaged (X K =1), and, in that case, the clutch is disengaged, a preselected starting gear is engaged, the clutch is at first kept disengaged and starting in the preselected starting gear is initiated in combination with a situation-dependent engagement of the clutch which is carried out as a function of actuation of the accelerator pedal (X K =f(X FP )), provided that the manual shift lever has not previously been actuated.
