  • Patent number: 11327124
    Abstract: In a ground fault detection apparatus, a first charge voltage of a detection capacitor measured with a positive electrode side of a high-voltage battery connected in series with a positive electrode side end of the detection capacitor and a negative electrode side end of the detection capacitor grounded, is compared with a second charge voltage of the detection capacitor measured with the positive electrode side end of the detection capacitor grounded and the negative electrode side of the high-voltage battery connected in series with the negative electrode side end of the detection capacitor. When the first charge voltage is smaller and degree of smallness is greater than a predetermined reference, it is determined that positive electrode side insulation resistance is decreased. When the second charge voltage is smaller and degree of smallness is greater than a predetermined reference, it is determined that negative electrode side insulation resistance is decreased.

  • Patent number: 10969304
    Abstract: A state detection system for an internal combustion engine is provided. A detection mapping takes, as inputs, rotation waveform variables and a road surface state variable to output a combustion state variable. The rotation waveform variables include information on a difference between cylinders in the rotational speed NE of a crankshaft during periods in which the respective cylinders generate combustion torque. The combustion state variable relates to a level of variations in combustion state among the cylinders. A determination process performed by an execution device determines whether the internal combustion engine is in a predetermined operating state based on an output value of the detection mapping that takes, as inputs, values of the rotation waveform variables and a value of the road surface state variable.

Vibrations produced by rotating components of the chassis system due to an imbalance are filtered such that the frequency range which depends on the wheel rotation speed and contains the imbalance-induced vibrations of the rotating components is filtered out. The signals from sensors associated with the component and arranged on the wheel carrier side and the vehicle body side, are received and stored. The amplitudes of these signals are sorted by increasing frequency and the mechanical impedance of the transmission chain is determined and compared with the known impedance of that component undamaged. If a deviation of the determined impedance for the component and the known impedance of the undamaged component is recognized, then the component is determined to have a defect and a flag is set.

The driving force distribution control device counts a number of tests performed by applying a test current to the inductive load circuit; determines that a disconnecting abnormality occurs in an electric load including the inductive load circuit if a difference between a value of the test current and a value of current flowing in the inductive load circuit is greater than a current difference threshold value; and determines that the disconnecting abnormality is definitive if the number of tests is equal to a threshold value or more, and also if the number of determinations of the disconnecting abnormality is equal to a predetermined threshold value or more.

  • Patent number: 8565959
    Abstract: Multiple leak rate methodologies are combined and operate in parallel in a system for providing optimal results under different tire conditions. The methodologies may operate continuously or alternatively. Tandem large leak rate and low leak rate algorithms and methodology, for example, may deployed in a system in which, for large leak rates, a large leak rate methodology is employed and used to trigger a warning. At some pre-designated low leak rate threshold value, the system employs a low leak rate methodology either as an exclusive diagnostic monitor or in parallel with the companion large leak rate methodology. In the low leak rate analytical system, a change in tire pressure is correlated to a change in energy within a vehicle system pursuant to the algorithm W=??P*dx and derivative algorithms are used to calculate a final time and pressure drop at the final time as a basis for issuing a low pressure warning.

  • Patent number: 8433472
    Abstract: A parameter identification-based fault isolation technique is provided for improving fault code settings and isolating faults. DTCs and PIDs are retrieved from a current serviced vehicle. PID data is obtained from prior serviced vehicles having same vehicle specifications as and under substantially similar operating conditions as the current serviced vehicles. A plurality of clusters is formed using PID data of the prior serviced vehicles using mutual dependence to one another. A joint probability distribution is determined as a function of a mutual dependence of the PID data. PID data is selected of the current serviced vehicle having coherence to the PID of the prior service vehicles. A mutual dependence of the PID data of the current serviced vehicle is projected on onto the corresponding joint probability distribution.
