    摘要: A system includes an out of correlation (OOC) detection module that detects an OOC error between a first throttle position sensor (TPS) and a second TPS. An out of range (OOR) detection module that detects first and second OOR errors for the first and second TPS, respectively. An OOC counter sets an OOC error when an OOC count is greater than or equal to a first OOC value. An OOR counter sets first and second OOR errors when first and second OOR counts, respectively, are greater than or equal to a second OOR value that is less than the first OOC value. A control module increments the counters when the respective errors occur and sets at least one of the first and second OOR counts equal to the OOC count when at least one of the first and second OOR errors occur after the OOC error.

    摘要: A system for an engine with a turbocharger system includes a rate determination module, a limiting rate selection module, a throttle inlet absolute pressure (TIAP) calculation module, and a throttle control module. The rate determination module generates a pressure rate value based on a pressure difference between a current TIAP signal from a TIAP sensor and a previous TIAP signal. The limiting rate selection module selects a limiting rate based on the pressure rate value. The TIAP calculation module generates a calculated TIAP signal based on the limiting rate and the current TIAP signal. The throttle control module generates a throttle control signal based on the calculated TIAP signal and actuates an inlet throttle valve of the engine based on the throttle control signal.

    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 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.
