    摘要: A system for a vehicle includes a first exhaust gas flow rate (EGF) estimation module, a second EGF estimation module, and an EGF fault detection module. The first EGF estimation module estimates a first flow rate of exhaust re-circulated back to an intake manifold based on a concentration of oxygen in the intake manifold. The second EGF estimation module estimates a second flow rate of exhaust re-circulated back to the intake manifold based on an engine speed and an engine load. The EGF fault detection module selectively indicates a fault is present in an exhaust gas recirculation (EGR) system based on the first flow rate and the second flow rate.

    摘要: A system and method for maintaining the voltage of fuel cells in the fuel cell stack below a predetermined maximum voltage. The method determines a desired voltage set-point value that defines a predetermined maximum fuel cell voltage value and uses the voltage set-point value and an average fuel cell voltage to generate an error value there-between. The method generates a minimum gross power prediction value using the modified voltage set-point value to prevent the fuel cell voltages from going above the predetermined maximum fuel cell voltage value and generating a supplemental power value based on the minimum gross power prediction value and the error value to determine how much power needs to be drawn from the stack to maintain the fuel cell voltage below the predetermined maximum voltage value. The method uses the supplemental power value to charge the battery or operate an auxiliary load coupled to the stack.

    摘要: A control system for a vehicle includes a motor driver module, a correlation triggering module, a target phase angle module, and a correlation control module. The motor driver module controls an electric camshaft phaser of an engine based on a desired phase angle between a position of a crankshaft and a position of a camshaft. The correlation triggering module selectively generates a signal based on the position of the camshaft. The target phase angle module adjusts the desired phase angle to a predetermined phase angle in response to the generation of the signal. The correlation control module, in response to the generation of the signal: determines the position of the crankshaft when the camshaft is in a predetermined position; and selectively outputs a fault indicator based on a comparison of the position of the crankshaft and a predetermined crankshaft position range corresponding to the predetermined position.

    摘要: A system and method for monitoring anode bleed trigger events and determining when to adjust a proactive bleed schedule in a fuel cell system. The system employs a bleed trigger monitor algorithm for monitoring proactive bleed and reactive bleeds that determines whether the reactive bleeds are caused by excess nitrogen in the anode. The algorithm monitors the number of reactive bleeds that are cause by nitrogen accumulation in the anode side of the fuel cell stack and changes the proactive bleed schedule in response thereto, if necessary.

    摘要: A system and method for putting a fuel cell vehicle system into a stand-by mode where there is little or no power being consumed, the quantity of fuel being used is minimal and the fuel cell system is able to quickly recover from the mode. The method includes determining whether predetermined stand-by mode vehicle level entrance criteria have been satisfied at a vehicle control level and predetermined stand-by mode fuel cell level entrance criteria have been satisfied for a fuel cell system control level, and putting the vehicle in the stand-by mode if both the vehicle level entrance criteria and the fuel cell level entrance criteria have been satisfied. The method exits the stand-by mode if predetermined vehicle level exit criteria have been satisfied or predetermined fuel cell level exit criteria have been satisfied.
