  • Patent number: 7442148
    Abstract: In a method for operating a motor vehicle in the event of a shift of a power divider actuated by external force, before the commencement of the shift of the power divider, a control device reduces the torque at the shifting members involved in the shift. The vehicle transmission is an automatic transmission, and the reduction is achieved a clutch in the automatic transmission is opened. After the conclusion of the shift, a torque is permitted again at said shifting members, and the clutch is closed again. The vehicle driver can consequently execute a shift in the power divider merely by triggering a shift requirement.

  • Publication number: 20060252598
    Abstract: 1. A method for operating a motor vehicle in the event of a shift of a power divider actuated by external force. 2.1. In known methods, a vehicle driver has to open a clutch actuated by foot force in the drive train, before a shift of the power divider can be executed. The object of the invention is to propose a method, by means of which it becomes possible for the motor vehicle to be operated comfortably. 2.2. According to the invention, before the commencement of the shift of the power divider (20), a control device (16) reduces a torque at the shifting members (23, 24, 25, 26) involved in the shift. The transmission is designed, in particular, as an automatic transmission (15), and the reduction is achieved in that a clutch (18) in the automatic transmission (15) is opened. After the conclusion of the shift, a torque is permitted again at said shifting members (23, 24, 25, 26), and the clutch (18) is closed again.

  • Patent number: 6736754
    Abstract: In a method for operating a motor vehicle having an automatic transmission in the time of a selection action for a driving-mode range, first a driver's requirement for a change in the driving-mode range is transferred to a selection device, a change signal is then generated by the selection device, the change signal is subsequently transferred to a control unit, and, finally, a change in the driving-mode range of the automatic transmission is brought about by the control unit according to the change signal. In the time of the selection action for the driving-mode range, at least one braking device is actuated in an automated manner by the or a control unit. Drive-train oscillations may be reduced or avoided by the method.
