  • Publication number: 20240149849
    Abstract: A method for controlling a braking system of a motor vehicle. The braking system includes hydraulically actuated wheel brakes as well as a linear actuator and a pump as electrohydraulic pressure-generating devices, according to which, during a braking operation of the motor vehicle, a parameter describing an actual behavior of the braking system of the motor vehicle is monitored and compared with a stored threshold value. In the event that the monitored parameter exhibits a defined deviation from the threshold value, the linear actuator and the pump are switched to synchronous operation by simultaneously operating the linear actuator and the pump and applying brake pressure to the hydraulically actuated wheel brakes via the linear actuator and the pump. A current volume consumption of the linear actuator is detected as a parameter describing the actual behavior of the braking system of the motor vehicle.

  • Publication number: 20240140305
    Abstract: A method for operating at least one direction indicator of a motor vehicle, wherein, as of an actuation time, the direction indicator outputs a light signal comprising a periodic repetition of alternately successive on-phases and off-phases. A discrepancy of a starting phase angle of the light signal with respect to a predefined reference signal is determined at the actuation time and is compared with a predefined target phase angle assigned to the direction indicator. When there is a phase offset between the starting phase angle and the target phase angle—at least two of the on-phases and/or the off-phases of the light signal are extended or shortened by a different time difference value in each case after the actuation time such that the phase angle of the light signal with respect to the reference signal then corresponds to the predefined target phase angle, and/or—the light signal is started with a first off-phase (11) at the actuation time.

  • Patent number: 11971547
    Abstract: Motion sickness of a user occurring when viewing media content by use of data glasses during a journey in a motor vehicle is reduced. Vehicle dynamics data and glasses dynamics data are registered and a displayed perspective is controlled by a control device based on the vehicle dynamics data and the glasses dynamics data. In the displayed perspective, the media content is displayed in a media field which is shown so it is visible through a frame element and an artificial environment is shown adjacent to the frame element. A velocity component of the vehicle dynamics data is represented as movement of the artificial environment and an acceleration component of the vehicle dynamics data is represented by an inclination of the frame element with respect to the media field and a movement component of the glasses dynamics data is represented as a shift of the entire perspective.

  • Patent number: 11971094
    Abstract: A drive apparatus for a vehicle having an electric machine whose rotor shaft is constructed as a hollow shaft having an internal tooth arrangement. A gear mechanism drive shaft, which has an external tooth arrangement, is inserted coaxially relative to the hollow shaft into the hollow shaft, to form a torque-transmitting spline. The rotor shaft with a rotor shaft rotary bearing being interposed is guided outward through a bearing opening of an electric machine housing, and the gear mechanism drive shaft has a centering seat which is in abutment with the internal circumference of the rotor shaft with a tight clearance fit. The gear mechanism drive shaft is subjected to bending (D) during travel operation as a result of radially active operating forces (FR). To reduce the bending stress (D), the centering seat of the gear mechanism drive shaft is arranged without an axial offset with respect to the rotor shaft rotary bearing, in axial alignment relative to the rotor shaft rotary bearing.
