  • Patent number: 11884346
    Abstract: A motor vehicle is controlled via a method, particularly for steering during a malfunction. Two wheels are arranged on a steerable axle of the motor vehicle and each can be driven by a single-wheel drive. At least one wheel is arranged on a non-steerable axle of the motor vehicle and can be driven by a wheel drive. In the event of a malfunction of one of the single-wheel drives being identified, a drive torque or a braking torque is generated with the functioning single-wheel drive of the wheel arranged on the steerable axle of the motor vehicle to steer the wheels arranged on the steerable axle in a specified direction. A drive torque or a braking torque is generated with the wheel drive of the wheel arranged on the non-steerable axle of the motor vehicle to at least partially bring about a specified longitudinal movement of the motor vehicle.

  • Publication number: 20230146720
    Abstract: A vehicle drive unit for a vehicle for omnidirectional driving of the vehicle. The vehicle drive unit includes a vehicle platform, a drive platform, and at least two wheels arranged on the drive platform, one drive unit being provided per wheel to drive the wheel. A controllable self-locking steering actuator is arranged between the drive platform and the vehicle platform. The steering actuator is rotatable about a longitudinal axis and is used to rotate the vehicle platform and the drive platform relative to one another, the steering actuator allowing a temporary blocking of the rotation. At least three pivoting wheels are arranged on the vehicle platform for vehicle stabilisation, each being rotatable about its own wheel axis and about its own vertical axis. A vehicle having a vehicle drive unit is also provide.

  • Patent number: 11446957
    Abstract: A hybrid connection element, in particular a bearing outer element of a wheel bearing, includes a core part made of steel and a reinforcement part made of plastic. The reinforcement part at least partially encases the core part. The core part includes a hollow cylindrical bearing unit extending in an axial direction and a flange extending in a radial direction. The reinforcement part includes at least one reinforcement rib which transmits force between the bearing unit and the flange of the core part.
