  • Patent number: 11831269
    Abstract: The disclosure relates to a method for controlling a first electric motor (M1) and a second electric motor (M2) of a wheel drive module, wherein the wheel drive module comprises a wheel (R) and a speed modulation gearbox (G), and wherein the wheel (R) is drivable about a wheel axis (A) jointly by the first and the second electric motors (M1, M2) by means of the speed modulation gearbox (G) and steerable about a steering axis (L) which is orthogonal to the wheel axis (A), wherein electrical control signals for controlling the first and second electric motors (M1, M2) are determined from wheel reference values which characterize the driving and/or the steering of the wheel (R).

  • Publication number: 20220065623
    Abstract: A method for determining state values of a wheel (R) of a wheel drive module that includes the wheel (R), a speed modulation gearbox (G), a first electric motor (M1) and a second electric motor (M2), as well as at least one first sensor (S1) for sensing state values of the first electric motor (M1), at least one second sensor (S2) for sensing state values of the second electric motor (M2), wherein additional state value sources of the electric motors (M1, M2) and/or the wheel (R) are provided and the sensed state values are compared with each other in order to compensate for and to recognize errors in the sensing of the state values so that actual state values of the wheel (R) are determined from the individual sensed state values.

  • Publication number: 20210316606
    Abstract: A wheel drive module comprises wheel (R), speed modulation gearbox (G), first electric motor (M1), and second electric motor (M2). First and second electric motors (M1, M2) jointly drive wheel (R) about wheel axis (A) by the speed modulation gearbox (G) and steer said wheel about steering axis (L). Wheel drive module comprises first motor electronics (10) for controlling first electric motor (M1) and second motor electronics (20) for controlling second electric motor (M2) and central electronics (30) connected to first and second motor electronics (10, 20), allowing a signal transfer. Wheel drive module comprises control logic for controlling first and second electric motors (M1, M2), which logic is provided by first and second motor electronics (10, 20), central electronics (30), application electronics (40) connected to the central electronics (30), allowing a signal transfer, or jointly by the central electronics (30) and the first and second motor electronics (10, 20).

  • Patent number: 10480505
    Abstract: An arrangement (100) for specifying the pressure (64), produced by a pump (30) driven by an electric motor (31), includes a processor (116) which derives a target pressure value (62, 118) from an internal torque value (114) and a loss torque (108). The arrangement (100) further derives (112) the internal torque value (114) from a motor current value (110) and a motor constant ke.
