  • Patent number: 11566572
    Abstract: In a method for operating an internal combustion engine of a motor vehicle having an automatic transmission, a torque generated by the internal combustion engine is reduced as a function of an operating state of a drive train of the motor vehicle. As a function of an excess of combustion air occurring when the torque is reduced and supplied to the internal combustion engine by an exhaust gas turbocharger, fuel combustion efficiency in at least one combustion chamber of the internal combustion engine, which is related to the torque generated by the combustion chamber, is reduced. The combustion efficiency is reduced by at least one late post-injection of fuel into the at least one combustion chamber of the internal combustion engine.

  • Patent number: 11548423
    Abstract: A method for controlling at least two mechanical oscillators, more particularly in a motor vehicle, where each oscillator oscillates at a frequency during operation and where the frequency can be controlled by the power applied to the oscillators, includes arranging a single sound transducer at a distance from the oscillators and capturing an electrical signal, where the electrical signal is subjected to a Fourier transform and thus a Fourier spectrum is determined. The frequency of each oscillator is determined from extreme values of the Fourier spectrum.

  • Patent number: 11442078
    Abstract: A mounting direction determination device and a mounting direction determination method of an acceleration sensor which can automatically determine the direction of the acceleration sensor mounted on a vehicle. The mounting direction determination device determines a mounting direction, relative to a vehicle, of the acceleration sensor that is capable of detecting a first acceleration in a first direction and a second acceleration in a second direction. A mounting direction determination unit determines the mounting direction by comparing values actually measured by the acceleration sensor with determination reference data. The determination reference data specifies a combination of the detection results of the first acceleration and the second acceleration and the mounting directions.
