  • Patent number: 11831325
    Abstract: A method of operating a pipelined analog-to-digital converter (ADC) having a plurality of output stages includes: performing a first calibration process for the pipelined ADC to update a parameter vector of the pipelined ADC, where components of the parameter vector are used for correcting nonlinearity of the pipelined ADC, where performing the first calibration process includes: providing an input signal to the pipelined ADC; converting, by the pipelined ADC, the input signal into a first digital output; providing a scaled version of the input signal to the pipelined ADC, where the scaled version of the input signal is generated by scaling the input signal by a scale factor; converting, by the pipelined ADC, the scaled version of the input signal into a second digital output; and calibrating the pipelined ADC using the first digital output and the second digital output.

  • Patent number: 11781639
    Abstract: An oil management system for a vehicle includes a differential housing, a transmission housing, a lubricant tank, a suction line, a lubricant pump, and an air suction pump. The transmission housing is connected to the differential housing in an air-tight manner, and a lubricant through-passage is defined between the transmission housing and the differential housing. The lubricant tank is provided in the differential housing and has a lubricant suction opening in a lower region. The lubricant pump conveys lubricant from the lubricant tank through the suction line and conducts the lubricant to the lubrication points in the differential housing and the transmission housing. The air suction pump pumps air from the lubricant tank into the transmission housing so that an excess air pressure is maintained in the transmission housing.

  • Patent number: 11754096
    Abstract: A pilot device for a hydraulic directional valve includes a displacement sensor, a pilot valve, an actuating device, a coil assembly, and a circuit board. The displacement sensor has a sensor axis and the pilot valve has a valve axis. The valve axis and the sensor axis are arranged substantially parallel to one another so as to lie in a reference plane. The actuating device and the coil assembly are arranged adjacent to one another. The circuit board is arranged parallel to the reference plane. In each case, to establish an electrical contact, the coil assembly, the actuating device, and an electrical plug connection are either soldered directly to the circuit board or are in breakable electrical contact with a respectively associated, rigid contact assembly. The contact assembly is soldered directly to the circuit board.

  • Patent number: 11691497
    Abstract: A transmission system suitable for operation with a drive machine includes an input shaft for a drive power, at least one output shaft for outputting drive power, a power-split transmission section having at least one variable transmission branch and a mechanical transmission branch, a manual transmission, a transmission system controller, and at least one first and second electric machine for generator and motor operation. The electric machines are electrically connected to one another. The drive power is divided up and conducted by the mechanical and variable transmission branch. An input-coupled, magnetically electric epicyclic gear stage brings together the variable transmission branch and mechanical transmission branch, and is activated by the second electric machine such that the output shaft of the transmission system rotates counter to a direction of rotation at the input shaft to provide a forward and reverse operation of the transmission system.

  • Patent number: 11670995
    Abstract: There is provided a system including a dual rotor electrical machine. The dual rotor electrical machine comprises a stator, an inner rotor including a first number of permanent magnet pole pairs, and a modulator including a second number of modulating segments. The system includes a controller configured to execute non-transitory machine readable instructions that, when executed by the controller, cause the system to determine a virtual position of an electromagnetic field of the stator based on a weighted sum of an angular position of the inner rotor and an angular position of the modulator, wherein weights in the weighted sum are based on the first number and the second number.
