  • Four-state brake module for use as a joint in a mechanical linkage
    Patent number: 10941821
    Abstract: A four-state joint brake module is provided to selectably stop or allow motion in both directions resulting in a mechanism that has four possible states: 1) allowing rotation only in a clockwise direction, 2) allowing rotation only in a counter-clockwise direction, 3) allowing free rotation in both directions, and 4) stopping motion in both directions. In robotic and other motion control applications the use of this four-state joint brake module in a multi-segmented linkage allows for position holding without continuous application of power and “fail safe” behavior. It further allows for the ability to toggle this useful state behavior independently in either direction and is relevant for robotic applications.

  • Braking control system and method for an environmentally friendly vehicle
    Patent number: 10933874
    Abstract: A braking control system and a braking control method for an environmental-friendly vehicle may forcibly discharge a part of the current charge amount of a battery when it is determined that the current charge amount of the battery reaches a maximum charge amount state by regenerative braking to exclude a regenerative braking prohibition condition according to the maximum charge amount state of the battery. The braking of the vehicle is thereby always performed by a sum of the regenerative braking amount and the hydraulic braking amount to reduce a braking load concentrated on a disk of a hydraulic braking brake.

  • Method for controlling an electronically slip-controllable power braking system
    Patent number: 10875510
    Abstract: A method for controlling an electronically slip-controllable power braking system of a motor vehicle. Power braking systems are equipped with a plunger unit, which includes a plunger piston accommodated in a plunger cylinder and delimiting a working chamber, for generating brake pressure in brake circuits. This plunger piston is actuatable by an electronically activatable drive in a pressure buildup direction or in the opposing spatial direction thereto in a pressure reducing direction. A time-limited drive of the plunger piston takes place in the pressure reducing direction as soon as an actual brake pressure generated by the plunger unit has reached a predefinable setpoint brake pressure and a decoupling of a wheel brake and the plunger unit from an associated brake circuit has taken place.
