Abstract:
1. A method for controlling a gear release in an automated multi-speed drive in a vehicle drive having a drive motor and a separating clutch, that is positioned between the drive motor and separating clutch and that can be optionally opened or closed by a clutch plate whereby a torque of the drive motor is reduced at a start of a shifting process so that shift elements to be decoupled during the gear release can be decoupled by an actuator with little shift power and the torque of the drive motor is not increased involuntarily by engaging the clutch, comprising the steps of: continuously determining a current vehicle acceleration (a determining a current initial vehicle acceleration (a determining a first and second vehicle acceleration value (a constantly comparing the current vehicle acceleration (a applying a shift force from the actuator on the shift elements to be decoupled when the current vehicle acceleration (a opening the clutch with the clutch plate when the current vehicle acceleration value (a
