  • Publication number: 20240364187
    Abstract: An electrical machine for a motor vehicle, having a rotor mounted rotatably about a rotational axis and has a hollow rotor shaft which encloses a shaft cavity, the hollow rotor shaft having an axial end with a shaft opening, a stationary lance guided through the shaft opening into the shaft cavity and has a fluid outlet opening, a cooling medium which is guided through the lance and sprayed via the fluid outlet opening onto an inner lateral surface of the hollow rotor shaft, an edge-sealed first outlet opening formed in a wall of the hollow rotor shaft, via which first outlet opening the cooling medium may escape from the shaft cavity, wherein, at a rotation speed n of the rotor of n?4,000 rpm over at least 15 seconds, an average film thickness dF of the cooling medium in the radial direction of the rotor is ?3 mm.

  • Publication number: 20240336148
    Abstract: A drive unit for an electrically driven vehicle, having an electric machine, for accelerating and/or braking the vehicle, a transmission unit, which is designed to transform a rotational speed of an output shaft of the electric machine to an output rotational speed of a transmission output shaft of the transmission unit, a friction brake unit having a functional fluid for cooling and/or lubrication, to convert kinetic energy of the transmission output shaft into thermal energy by friction, and a housing having a first housing region, in which the electric machine is arranged, a second housing region, in which the transmission unit is arranged, and a third housing region, in which the friction brake unit is arranged. The first housing region, the second housing region and the third housing region are formed integrally with one another, and at least the third housing region is sealed off with respect to the environment.

  • Publication number: 20230286395
    Abstract: A method for controlling an electromotive drive of a motor vehicle. At least one of the motor vehicle wheels can be driven by an electric motor of the electromotive drive and the electromotive drive has at least one energy source for the electric motor. The method includes: identifying a request for applying a deceleration torque to the vehicle wheel, identifying status of the electromotive drive, selecting an operating mode of the electric motor according to the identified status, and controlling the electric motor in the selected operating mode for applying the deceleration torque. In a first operating mode, the electric motor is controlled such that the rotational energy of the vehicle wheel is converted at a first efficiency into electrical energy. In a second operating mode, the electric motor is controlled such that the rotational energy of the vehicle wheel is converted at a second efficiency into electrical energy.

  • Patent number: 10246092
    Abstract: A method that determines a driving state of an external motor vehicle includes: detecting the external motor vehicle by at least one sensor, the external vehicle moving in a longitudinal direction; determining a reference for a motion of the external motor vehicle transverse to the longitudinal direction; determining a first distance between the external motor vehicle and the reference at a first point in time; determining a second distance between the external motor vehicle and the reference at a second point in time lying after the first point in time; determining a difference between the first distance and the second distance; and determining the driving state as assistance-supported if the difference is less than or equal to a specified value.
