  • Patent number: 9623748
    Abstract: A method for operating a drive train of a motor vehicle includes the steps: detecting at least one variable; quantifying and/or influencing a movement of the motor vehicle; depending on the variable, switching on an all-wheel drive of the motor vehicle; wherein it is estimated on the basis of the at least one variable whether a relevant driving situation is impending and in this case the all-wheel-drive is switched on before occurrence of the relevant driving situation. A system for operating a drive train of a motor vehicle is also disclosed.

  • Patent number: 9387852
    Abstract: A method for adjusting the spatial position of the roll axis of a motor vehicle includes: a) defining a desired spatial position of the roll axis; b) determining a transverse acceleration of the motor vehicle; c) defining a desired transverse tilt of the motor vehicle and determining a desired transverse offset of the motor vehicle as a function of the transverse acceleration, so that the roll axis is moved into the desired position when the desired transverse tilt and the desired transverse offset are adjusted; d) adjusting a first actuator of an active chassis system of the motor vehicle, so that the motor vehicle assumes the desired transverse tilt determined in step c); and adjusting a second actuator to influence the transverse movement of the motor vehicle, so that the motor vehicle assumes the desired transverse offset determined in step c).

  • Patent number: 9199648
    Abstract: In a method for operating a motor vehicle which includes a control device for automatically and driver independently switching at least one drive unit of the motor vehicle on or off at standstill, as a function of at least one item of position related road information which relates to the actual position of the motor vehicle on a road and the presence of at least one further boundary condition, only the at least one item of position related road information is determined and, when the at least one position related road information satisfies at least one road related criteria, the presence of the at least one further boundary condition is not queried.

  • Patent number: 9193381
    Abstract: In a method and an apparatus for affecting the cornering performance of a motor vehicle, a transverse acceleration of the motor vehicle is determined, a desired transverse tilt of the motor vehicle defined based on the determined transverse acceleration, at least one actuator of an active suspension system of the motor vehicle is adjusted so that the motor vehicle assumes the desired transverse tilt, and an additional actuator intervening in the steering system of the motor vehicle. A yaw movement of the motor vehicle caused by the adjustment of the at least one actuator of the active suspension system is at least partially compensated by the additional actuator.

  • Patent number: 8645026
    Abstract: In a method for the operation of a transverse guiding driver assist system of a motor vehicle, a road banking information is ascertained as a function of a change in a deviation of a transverse course of a road surface from a horizontal. A future road course is determined from environmental data and/or operating data of a motor vehicle, using the road banking information. A lateral track deviation is determined as a result of a change of a road banking, using the road banking information. At least one transverse guiding parameter is established from the future road course and the road banking information to determine a steering intervention. The lateral track deviation is then corrected by using the transverse guiding parameter.
