  • Systems and methods for compensation for a dynamic axle load transfer
    Patent number: 7725251
    Abstract: The present invention proposes an improved method for at least partially compensating for the dynamic transfer of an axle load when part of a motor vehicle load dips over at least one front wheel. A demand for a drive moment is applied and thus a time-limited virtually maximum drive moment is produced for the purposes of compensating for the transfer of the axle load. Moreover, for the first time, the present invention proposes a microprocessor and also a control device for carrying out this method in accordance with the invention. Furthermore, a motor vehicle drive is indicated which is equipped with such a control device or such a microprocessor. Finally, software is designated for carrying out the method. A motor vehicle is presented which is equipped with such a control device or such a microprocessor for the execution of the software for carrying out the method in accordance with the invention.

  • Method for assessing the phase angle of a camshaft of an internal combustion engine, in particular for a motor vehicle
    Patent number: 6650994
    Abstract: A method for check the phase adjustment of a camshaft, in which the present phase angle of a variable phase camshaft can be detected reliably. A first value which corresponds to the actual noise level of the internal combustion engine is determined during a predetermined evaluation window and is compared with a second value, which corresponds to the actual noise level after phase adjustment of the camshaft, with the operation of the phase adjustment of the camshaft being assessed as a function of this comparison.

    Publication number: 20020095978
    Abstract: In order to check the phase adjustment of a camshaft, in which process the present phase angle of a variable phase camshaft can be detected reliably, a first value which corresponds to the actual noise level of the internal combustion engine is determined during a predetermined evaluation window and is compared with a second value, which corresponds to the actual noise level after phase adjustment of the camshaft, with the operation of the phase adjustment of the camshaft being assessed as a function of this comparison.
