Abstract: A method of controlling an automatic transmission of a vehicle in which a hold gear function is activated by a driver request and deactivated depending on a return condition. The method comprises the step of (a) determining the return condition by a change in operating state, and (b) deactivating the hold gear function if a temporary operating state, for which the hold function is requested, ends and a change takes place between one of uphill driving and downhill driving and between driving one of up and down a hill and driving on a same plane.

Abstract: A method of eliminating a tooth-on-tooth position at an interlocking shifting element. The tooth-on-tooth position is eliminated by operating at least one actuator such that, during a first operating attempt the actuator is operated using a defined target parameter, after which it is checked whether as a result of the operation of the actuator the tooth-on-tooth position has been eliminated. If the tooth-on-tooth position is not eliminated, then repeating subsequent operating attempts of operation of the actuator, each time with an increased target parameter, until, after the corresponding operation of the actuator, the tooth-on-tooth position is eliminated by the m-th operating attempt. For elimination of a subsequent tooth-on-tooth position, the target parameter defined for the first elimination attempt is adapted such that the subsequent tooth-on-tooth position is eliminated by an n-th attempt.
