  • Publication number: 20240343246
    Abstract: A controller of a motor vehicle comprises a drive motor, wheels, braking devices for the wheels, said braking devices being separately controllable by the controller, an ambient sensor, a driving status sensor and a steering system. For increasing the driving stability, a steering angle is determinable by the controller from signals of the ambient sensor and of the driving status sensor, said steering angle providing a stable driving status in addition to a targeted braking of the wheels, and the steering angle is adjustable at the steering system in order to keep the motor vehicle on the paved road, in particular when driving along a curve, so that the motor vehicle remains on an intersecting plane of the possible dynamic vehicle area ahead with an actual road without skidding or colliding with other obstacles.

  • Patent number: 11626812
    Abstract: A method controls switching states of a multi-level converter with multiple modules. Each module has: terminals on a first and second side; controllable switches; and an energy store in series with a first switch in a first connection between the terminals. A second switch is arranged in a connection between the terminals. The control of the switching states is divided into a real-time and offline part. In the real-time part, for each time step: a voltage level is allocated to a voltage requirement; a total switching state is determined in a first switching table for the voltage level; and the total switching state is passed on as a control signal to the switches. In the offline part: a second switching table is calculated, resulting in accordance with a minimization of a cost function.
