    摘要： A system is provided for implementing a series interlock loop. An example of the interlock system includes a series interlock loop, a data table, and a control module. The series interlock loop has an overall electrical characteristic. The series interlock loop includes first and second safety interlocks electrically coupled in series. Each interlock includes a switch coupled in parallel with an impedance value. The data table is configured to store values corresponding to the impedance values. The control module is communicatively coupled to the data table and configured to receive an indication of the overall electrical characteristic and to compare the overall electrical characteristic to the values in the data table to thereby identify an open one of the first and second safety interlocks.

    摘要： A hybrid electric vehicle (HEV) has an algorithm for executing a method for diagnosing a high-voltage (HV) fault condition aboard the HEV. The HEV includes a high-voltage (HV) battery, an auxiliary power module (APM), a power inverter module (PIM), and a three-phase motor/generator unit (MGU). A controller executes the method to thereby measure a DC output current from the HV battery, a DC inlet current into the APM, and a pair of AC phase currents in the MGU. The method further includes calculating a DC inlet current into the PIM using the AC phase currents, diagnosing the HV fault condition using the DC output currents and the DC inlet currents, and executing a control action in response to the diagnosed condition. The method can include shutting off the APM to determine whether the APM is the root cause of the HV fault condition.

    摘要： The derivative of a noise-containing input signal is determined by using an aliased derivative to periodically reset a filtered version of a normally determined derivative. The aliased derivative is calculated using a slower update or sampling rate than the normally determined derivative, and the filtered version of the normally determined derivative is reset to a reset value at each update of the aliased derivative. The reset value is based on a weighted sum of the aliased derivative and the filter output. The periodically reset filter output closely follows an idealized derivative of the input signal, substantially eliminating the phase delay introduced by conventional filtering.
