  • Publication number: 20190236228
    Abstract: A method of providing stable communication between subsystems in a co-simulation system, including providing a signal S1 describing an output angular velocity of a rotating body of the first physical system; filtering the signal S1 using a continuous moving average, CMA, filter; and forming a time discrete first output signal S1*. In a second subsystem the signal S1* is received and the angular velocity described by S1* is applied to the second physical system. A response signal S2* describes a torque generated by the second subsystem. The response signal S2* is received by the first subsystem where a time discrete feedback signal SF* is formed based on the difference between the response signal S2* and a time discrete damping signal SD*.

  • Patent number: 10296706
    Abstract: A method for control and co-simulation in a system having multiple subsystems, each representing a physical system, includes, in a first subsystem simulating a first physical system, providing a first time continuous output signal representing a property of the first physical system, and filtering the output signal using a continuous moving average (CMA) filter as an anti-aliasing filter to form a filtered time continuous signal. Filtering the output signal includes integrating the time continuous signal to form an integrated signal, sampling the integrated signal, for each sample, forming an average value from the current sample and a previous sample, and forming a filtered time continuous signal from the average values. The method also includes providing the filtered time continuous signal to a second subsystem simulating a second physical system. A system for performing the method is also provided.

  • Publication number: 20080288149
    Abstract: A method of regulating the driving dynamics of a vehicle by controlling a torque distribution from a vehicle engine between at least two axles of the vehicle is disclosed. The method comprises controlling the torque distribution with a nominal velocity difference between the different axles as an input value. According to an embodiment, the sign of the velocity difference between both outgoing shafts from the double coupling device is used to determine a control state of the double coupling.

  • Publication number: 20070244620
    Abstract: The present invention relates to a method for controlling a vehicle comprising an all-wheel drive coupling, which is engaged by a clutch, and an electronic stability program (ESP) system being connected to a brake system of the vehicle. In the method, the ESP system and the all-wheel drive coupling exchange information for improving the controllability of the vehicle during cornering. The invention also relates to an all-wheel drive system for performing the above method.
