Abstract
A method of controlling a drivetrain of a vehicle in which the drivetrain comprises a motor, a transmission with starting gears and a clutch located between the motor and transmission, a manual shift lever, and a control unit, for controlling the transmission and clutch, that communicates with a speed sensor, and an accelerator pedal and shift lever actuation sensors. When starting off from coasting, a starting gear is determined in a manner that can be influenced by the driver via actuating the manual shift lever. To assist the driver, it is checked whether the transmission is in neutral and the clutch is engaged, if the vehicle speed is within a specified speed range. If so, the clutch is disengaged, another gear is engaged, and starting is initiated in combination with situation-dependent clutch engagement and carried out as a function of accelerator pedal actuation, provided the shift lever has not been actuated.
