  • Publication number: 20210159888
    Abstract: A device for signal processing includes a signal input, a control input, and a CIC filter of an nth order for filtering the input signal. The CIC filter includes n integrators, which are disposed one behind the other and include a memory in each case, and n is greater than one. For each of n?1 first integrators, the device includes an associated correction calculator for correcting an integration error using at least one signal value stored in the memory of the respective first integrator. The device transmits these stored signal values in response to the control signal to the associated correction calculators and to delete the memory of the remaining last integrator. Either the memories of the n?1 first integrators are also deleted, or the device includes a further correction calculator and the signal values are transmitted in response to the control signal also to the further correction calculator.

  • Patent number: 11018894
    Abstract: A method of transmitting a communication signal and electric power between two user stations of a bus system includes coupling the communication signal into a bus line via a low-pass filter that filters the communication signal, such that signal frequencies below a cut-off frequency of the low-pass filter are coupled into the bus line of the bus system. The method also includes coupling, using a power coupling device, electric power in the form of a high-frequency signal into the bus line, transmitting the communication signal and the electric power as a bus signal to an electrical load using the bus line, and decoupling the communication signal from the bus line via a low-pass filter that filters the bus signal, such that signal frequencies below the cut-off frequency of the low-pass filter are decoupled from the bus line of the bus system.

  • Patent number: 11015620
    Abstract: A servohydraulic drive includes a hydrostatic displacement machine, an electric machine that is mechanically speed-coupled with the displacement machine, a hydraulic cylinder that is fluidically connected to the displacement machine via first and second working lines, a hydraulic accumulator, and a supply unit. The displacement machine has a stroke that is adjustable via a hydraulic adjustment device. The cylinder is configured to be activated by reversal of the fluid flow through the displacement machine in opposite directions. The accumulator is preset to a low pressure and is fluidically connected via a valve assembly in each case to the lower pressure working line. The supply unit is configured to supply the adjustment device with pressurized fluid under the necessary pressure for the adjustment regardless of the present pressure in the working lines such that the displacement machine is configured for an active and load pressure-independent adjustment of its stroke volume.

  • Patent number: 11018603
    Abstract: A drive unit for an adjustment system for a motor vehicle has an adjustable element moved by an electric motor. The dive motor is operated electromagnetically. A magnetic field sensor is arranged on a pole pot or a housing of the drive motor to provide an electrical sensor signal dependent on a magnetic field. A control unit is configured to detect the magnetic field. The magnetic field varies on rotation of a rotor of the drive motor, so that a relative position change of the adjustable element can be derived from the electrical sensor signal.

  • Publication number: 20210146903
    Abstract: In a method, which can be performed by a control device for carrying out an emergency braking and/or panic braking of a vehicle, in a first phase, a setpoint vehicle deceleration requested instantaneously by a driver is ignored and a motor of an electromechanical brake booster is operated in a predefined high power mode such that a main brake cylinder pressure in the main brake cylinder is increased; in an intermediate phase, the main brake cylinder pressure is reduced to a setpoint pressure by pumping brake fluid from the main brake cylinder into the at least one wheel brake cylinder and the motor force of the motor is reduced to a setpoint force; and the brake pressure increase in the at least one wheel brake cylinder is continued during a second phase only if the driver requests instantaneously a setpoint vehicle deceleration.
