  • Patent number: 10345351
    Abstract: The present disclosure relates to a method for monitoring an on-board electrical system of a vehicle having at least one distributor and a load that are connected together via a cable. In one implementation, the method includes reading in a sequence of data for a number of parameters representing information about operation of the vehicle by a driver and/or about a state of the vehicle and/or a state of the driver and/or a driving environment; classifying the data as a normal value or an error value; and evaluating the data classified as an error value or a normal value. The normal values may lie within a state space separated from the error values by a discrimination limit. Evaluating the data classified as an error value may include determining if the data classified as an error value fulfils a criterion, and evaluating the data classified as a normal value may include statistically evaluating to determine a stochastic parameter and determining if the stochastic parameter exceeds a threshold value.

  • Patent number: 10317245
    Abstract: An electric machine (e.g., motor or generator) for an electric drive system of an electric vehicle is adapted to be coupled to wheels of the vehicle for conversion between stored electrical energy and rotation of the wheels. A resolver is coupled to the electric machine having a rotor rotating with the electric machine, the resolver responding to an excitation signal to produce a position signal. A controller is coupled to the resolver to receive the position signal and coupled to the electric machine to control the conversion. The controller generates the excitation signal at a variable frequency selected as a function of an operating point of the electric machine to avoid harmonic noise peaks propagating at the electric machine. Consequently, the position signal is relatively less affected by electromagnetic noise.
