    摘要: An error condition detection circuit coupled to the motor control circuit reports an error condition when actual motor operation deviates from predetermined desired motor operation. An overcurrent threshold comparator compares motor current with a threshold data value stored in a data storage register, and sets an overcurrent flag when the motor current exceeds the threshold. A current interrogation processor monitors the reported error condition and is programmed to respond to the error condition by iteratively reading the overcurrent flag and decrementing the overcurrent threshold data value by a predetermined decrement amount until the overcurrent flag becomes set. The current interrogation processor is further programmed to report the overcurrent threshold data value extant at the time the flag becomes set as an estimate of electric current.

    摘要: A control system comprising a powertrain relay diagnostic module that determines a single continuous period that a powertrain relay voltage is less than an ignition relay voltage, that compares the single continuous period to a single predetermined period, and that diagnoses a powertrain relay out of correlation (OOC) error when the single continuous period is greater than or equal to the single predetermined period, and an ignition relay diagnostic module that diagnoses an ignition relay OOC error when the ignition relay voltage is less than the powertrain relay voltage for a first predetermined cumulative period within a first predetermined total period.

    摘要: A diagnostic system includes N dedicated diagnostic modules that each correspond with a respective one of multiple control systems. The N dedicated diagnostic modules each generate status signals indicating results of respective diagnostic tests. A diagnostic error time monitor determines an accumulated error time value between error events for each of the control systems based on the status signals. The diagnostic error time monitor selectively reports a fault to a respective one of the N dedicated diagnostic modules based on the accumulated error time value.

    摘要: A control system for a vehicle comprises a throttle control module and a diagnostic module. The throttle control module controls a position of a throttle of the vehicle and compensates for changes in effective opening area of the throttle due to coking. The diagnostic module reports a coking value to a user based upon an amount of compensation performed by the throttle control module. A method comprises controlling a position of a throttle of a vehicle; compensating for changes in effective opening area of the throttle due to coking; and reporting a coking value to a user based upon an amount of compensation performed.

    摘要: Barometric pressure is determined in a hybrid electric vehicle from manifold absolute pressure. During engine operation, wide open throttle is commanded and output torque disturbances are offset by the electric machine. Barometric pressure is estimated based on sensed intake manifold pressure and engine speed dependent pressure offsets. During engine shut down, barometric pressure may be determined from manifold pressure without any offset adjustments.
