  • Patent number: 11438028
    Abstract: A communication set-up having an electronic circuit; the circuit including at least one communication unit for wireless communication. The communication unit includes an antenna network connected to an antenna; and also includes an actuating unit. The circuit of the communication set-up further includes a signal processing unit, and in response to operation of the actuating unit, the actuating unit is configured to release a signal to the signal processing unit, which, on the basis of this, converts the communication set-up from a blocked state to an enabled state, or vice versa. In addition, a method for controlling such a communication set-up is described.

  • Patent number: 9162582
    Abstract: A method for operating a motor vehicle, including at least one electric motor connected to at least one rechargeable energy storage unit that stores electrical power, wherein the charging operation of the energy storage unit is carried out in such a way that a charging state limit that lies below the maximum charging state of the energy storage unit is not exceeded, wherein upon activation of at least one vehicle starting system, which is designed to automatically carry out a maximum acceleration of the motor vehicle from the standing position, the charging operation of the energy storage unit is carried out before the acceleration of the motor vehicle in such a way that the energy storage unit is charged up to a further charging state limit that lies above the first charging state limit and/or at least one further rechargeable energy storage unit is connected in series

  • Patent number: 8955345
    Abstract: A method for operating a motor vehicle having at least one electric drive component which is cooled via at least one coolant circuit which is coupled thermally to a refrigerant circuit. In a first operating mode of the motor vehicle, an inlet temperature of a coolant of the at least one coolant circuit is set to a first value by active cooling by means of the refrigerant circuit. In a second operating mode, in particular a sports operating mode of the motor vehicle, the inlet temperature is lowered with respect to the first operating mode. As a result, more pronounced cooling of the components is made possible in the second operating mode, as a result of which the maximum driving power of the motor vehicle is increased.

  • Patent number: 8831859
    Abstract: The functionality of a “Launch Control” is implemented in a hybrid vehicle, i.e. the hybrid vehicle can be accelerated to a maximum degree by starting the internal combustion engine immediately from the stationary state (S20), and acceleration takes place with the aid of the electric motor with full torque (S22) before a changeover to accelerating the internal combustion engine takes place (S24). The “Launch Control” differs from a further mode in which firstly acceleration takes place from the stationary state using a partial torque of the electric motor (S14), with the result that the internal combustion engine can be tow-started by means of the electric motor (S16) before a changeover to acceleration using the internal combustion engine (S18) occurs.
