  • Publication number: 20210284124
    Abstract: A method for controlling the longitudinal dynamics of a vehicle, where the vehicle has a friction brake system brakes, a drive system with an electromotive drive acting on at least one wheel, and a battery for supplying power to the electromotive drive determines state information which describes the state of the vehicle and/or the state of the brake system and/or of the drive system. Route information is determined which describes the route profile of the vehicle. An action plan for implementing a future braking request by the friction brakes and/or the electromotive drive on the basis of the state information and the route information is determined. The action plan specifies, for future times and/or areas on the route, whether a braking request of the vehicle is to be implemented by means of the friction brake and/or the drive system and implements a braking request accordingly.

  • Patent number: 11072316
    Abstract: A braking device for a hydraulic motor vehicle braking system having an electromechanically driven booster stage and a ball screw drive. In order to provide a braking device which is of particularly compact, cost-effective and weight-saving construction and has short pedal strokes, and an easily adjustable pedal characteristic curve, at the same time enabling effective direct action in case of failure of the booster stage and comfortable haptic feedback at the pedal during normal operation, the actuating force from a piston rod is introduced into the spindle, wherein the piston rod can be moved axially to a limited extent relative to the spindle and a spring element is inserted in the flow of force of the actuating force between the piston rod and the spindle, which spring is compressed axially when the actuating force is introduced.

  • Publication number: 20210040528
    Abstract: Herein is reported a feed mixing device for adding feed solutions with a non-physiologically pH value to a cell cultivation vessel comprising a chamber for mixing the feed solutions prior to their addition to the cell cultivation vessel as well as its use. With the feed mixing device as reported herein feed components can be provided in solution at a pH value at which they have good solubility and/or good stability whereby the pH value can be clearly different from the pH value of the cultivation medium, i.e. different from the physiological pH value. This allows performing the cultivation with more flexibility compared to a cultivation in which the pH value of the feed solution is limited to a small range around the pH value of the cultivation.

  • Publication number: 20200143606
    Abstract: A method for detecting non-approved parts in a vehicle includes generating a plurality of component identifiers (IDs) for a plurality of components, wherein each component ID identifies a unique component of the plurality of components. The component IDs are stored to a decentralized database. A vehicle identifier (ID) that uniquely identifies a vehicle is generated and stored to the decentralized database. Component IDs associated with components of the vehicle that are stored in the decentralized data base are associated with the vehicle ID. The method includes subsequently, determining that a component of the vehicle has been replaced with a replacement component and searching the decentralized database for a component ID associated with the replacement component.

  • Patent number: 10400659
    Abstract: A coolant pump for an internal combustion engine (ICE) in a vehicle with a central engine control, having a pump shaft that drives an impeller for pumping a coolant. An axial piston pump operated via a wobble plate on a rear face of the impeller, conducts part of the pumped coolant away to a hydraulic circuit that extends from the axial piston pump via a proportional valve back to the pumped coolant and has a branch-off between the axial piston pump and the proportional valve as the hydraulic actuator. A regulating slide valve adjusts coolant volume flow of depending on pressure in the hydraulic circuit. A sensor detects a parameter characteristic of the coolant volume flow and outputs an actual value signal. A dedicated pump control controls the proportional valve based on the actual value signal of the sensor and a desired value signal of the central engine control.
