  • Patent number: 10654464
    Abstract: A method for compensation of a support torque at a combustion engine and transmission which provide an overlay of combustion engine and electric machine. The combustion engine, the electric machine, and a transmission gearset are connected with each other via a planetary gearset, which is positioned in front of a downstream transmission gearset. The invention concerns a transmission gearset of a three-shaft transmission, each with a transmission input shaft for the electric machine, and for the combustion engine, and an output shaft. For the connection or disconnection of the transmission input shaft of the electric machine while driving, the electric machine is used for the synchronization of the input shaft of the electric machine, and the created support torque at the combustion engine is determined, based on this support torque, to match a combustion engine torque and thus to compensate the support torque.

  • Patent number: 9555805
    Abstract: A method of releasing a stuck vehicle, in which a stuck situation is recognized and a rocking-free process is initiated and continued until the rocking-free process is suppressed. The rocking-free process is suppressed either after the activation of a parking brake of the vehicle, which was inactive at the beginning of and during the rocking-free process, for a predetermined time interval, or after the registration of a limit value of a deflection of a drive pedal of the vehicle and after the limit value of the deflection of the drive pedal is maintained or exceeded for a predetermined time interval, or after a vehicle speed falls to almost zero km/h, a minimum actuation of a drive pedal of the vehicle is registered, the vehicle speed is maintained for a predetermined time interval and the minimum actuation is maintained for the predetermined time interval.

  • Publication number: 20150291170
    Abstract: A method for releasing a vehicle from a recognized stuck condition including initiating a rocking-free process which is continued until the rocking-free process is automatically discontinued. The rocking-free process is discontinued after the registration and persistence of a vehicle movement for a predetermined time span while, at the same time, vehicle acceleration is registered for the predetermined time span, the extremes of the acceleration during the time span lie within a band-width-limited vehicle acceleration function range whose limits correspond almost to the global extremes of the vehicle's acceleration, or after reaching and maintaining or exceeding a vehicle speed limit value for a predetermined time span and reaching or exceeding a steering path limit value during the predetermined time span, or after the activation of a door switch which was inactive before the beginning of the rocking-free process and maintaining the switch active for a predetermined time span.

  • Publication number: 20150291169
    Abstract: A method of releasing a stuck vehicle with a rocking-free process which continues until the process is suppressed. The process is suppressed after a differential lock, closed at the beginning of the process, remains open for a predetermined time, or after reaching and maintaining a clutch load limit for a predetermined time, or after reaching a limit transmission gear, and maintaining the limit value for a predetermined time, or after registering the wheel rotational directions while a transmission gear engages, and after a predetermined time, in which the registered wheel rotational direction corresponds to a required direction for the gear engaged, or after a transmission gear is engaged, a transmission condition is maintained for a predetermined time, engaging a clutch for the predetermined time, a wheel speed difference limit value is reached, and the wheel speed difference remains at or falls below the speed difference limit value for the predetermined time.
