  • Patent number: 12337777
    Abstract: A motor vehicle includes a body component and a wing element pivotably coupled to the body component such that the wing element pivots relative to the body component about a pivot axis between a neutral starting position and a first pivot position. A control device of the motor vehicle detects an impending collision of the motor vehicle with a collision object located in the surroundings of the motor vehicle. Upon detecting the impending collision, the control device automatically pivots the wing element toward the body component from the neutral starting position to the first pivot position. The control device of the motor vehicle evaluates a severity of the collision and, depending upon the severity, automatically pivots the wing element away from the body component from the first pivot position to the neutral starting position.

  • Patent number: 12328033
    Abstract: A method for checking a model temperature of an electrical machine ascertained by a temperature model. At least one manipulated variable relating to the electrical machine is specified by a regulation of the electrical machine as a function of a setpoint variable. A model value of the manipulated variable is ascertained as a function of the manipulated variable and the model temperature from a machine model comprising at least one temperature-dependent parameter. A difference between the actual manipulated variable of the regulation and the model value of the manipulated variable and/or a difference between a variable derived from the actual manipulated variable of the regulation and a corresponding further variable derived from the model value of the manipulated variable is ascertained. The difference is compared to a limiting value and, if the limiting value is exceeded, a deviation of the model temperature from an actual temperature of the electrical machine is detected.
