    摘要: 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.

    摘要: A method for shift control of an automated auxiliary transmission that is mounted in a drive train of a motor vehicle between a drive motor (AM) and a final drive, and includes at least one multi-step main gearing (HG) and one two-step front-mounted group (VG) connected upstream of the main gearing (HG), and with which the main gearing (HG) can be shifted via unsynchronized clutches and the front-mounted group can be shifted via synchronized clutches. Depending on the currently existing driving or operating situation, a gear change is performed in the auxiliary transmission through a change in the transmission ratio step (G1, G2, G3) of the main gearing (HG) while maintaining the currently engaged transmission ratio step (K1, K2) in the front-mounted group (VG).

    摘要: A method of controlling and regulating a transmission brake which, for the purpose of synchronization, determines a target rotational speed of a shaft to be synchronized on the basis of an actual rotational speed of a transmission shaft, and controls a transmission brake such that the determined target rotational speed is set for the shaft that is to be synchronized. The transmission brake also carries out additional functions. These functions require no, or only minimal, additional hardware complexity in a cost-neutral way, but considerably increase the functional and practical value of the transmission brake. The comfort and speed of shifting operations, the protection or, as the case may be, the detection of error states in sensors, a clutch, a main clutch or a motor control are improved, and undesirable transmission states avoided. It is also possible to account for and influence other conditions, such as the operation of ancillary devices.

    摘要: A method of controlling the gear shifting of an automatic range-change transmission, which is arranged between a drive engine and a final drive in a drive train of a motor vehicle and includes at least one mufti-stage main transmission, a two-stage front-mounted group upstream of the main transmission, and a transmission brake. The main transmission can be shifted, via unsynchronized clutches, and the front-mounted group can be shifted, via synchronized clutches. Upon upshifting in the range-change transmission including at least one change of a transmission ratio stage of the front-mounted group, synchronization of the front-mounted group is effected via actuation of the synchronized clutch of the front-mounted group and supportingly via at least intermittently parallel actuation of the transmission brake. Actuation of the transmission brake, for supporting the synchronization of the front-mounted group, is effected on the basis of a prevailing driving or operating situation.

    摘要: A method of operating a motor vehicle drive-train having a drive aggregate, a group transmission and a drive output. The aggregate can couple an input shaft of the transmission which includes main, splitter and range groups. To carry out a shift, a target gear and target rotational speed of the aggregate are calculated for the shift to be carried out. After the initiation of the shift a load reduction is first carried out, then a group of the transmission is disengaged in order to shift the transmission to neutral, after which a group of the transmission is synchronized and to shift out of neutral, the synchronized group is engaged, and then the load is again built up. Initiation of the shift, after calculating the target gear and the target rotational speed, occurs at a point in time when complete performance of a shift is not yet possible.
