Abstract
Description
- The present disclosure relates to fuel injection systems and more particularly to improved diagnostic systems and methods for detecting fuel injection system failures.
- The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
- In a spark ignition direct injection (SIDI) system, highly pressurized fuel is injected via a common fuel rail directly into a combustion chamber of each cylinder in an engine. The SIDI design may provide a more efficient distribution of an air/fuel mixture in the cylinders than conventional multi-port fuel injection, which injects fuel near intake ports of the cylinders. More efficient air/fuel distribution may provide improved fuel efficiency, higher power output, and reduced emission levels at low load conditions.
- An onboard diagnostic (OBD) system monitors the individual components of the SIDI system and records errors detected with any of the individual components. Diagnostic trouble codes (DTCs) for various errors and malfunctions may be predefined by standards, such as second generation OBD (OBD-II). DTCs set by the OBD system may be read by service tools owned by dealerships and/or repair facilities. The OBD system may also notify an operator of the vehicle when one or more DTCs have been set.
- An engine control system includes a driver module and a diagnostics module. The driver module includes a high-side driver and a low-side driver. The high-side and low-side drivers selectively actuate a load. The driver module analyzes a plurality of failure modes of the high-side and low-side drivers. The driver module generates status signals based on detection of each of the plurality of failure modes. The diagnostics module stores a first error count for each of the plurality of failure modes and stores a total count. The diagnostics module increments the first error count for a first mode of the plurality of failure modes when the status signals indicate the driver module has detected the first mode. The diagnostics module increments the total count each time the driver module analyzes the first mode. The diagnostics module sets a fail state for a diagnostic trouble code (DTC) when the first error count for the first mode reaches a first predetermined threshold prior to the total count reaching a second predetermined threshold.
- A method includes selectively actuating a load using a high-side driver and a low-side driver; analyzing a plurality of failure modes of the high-side and low-side drivers; generating status signals based on detection of each of the plurality of failure modes; storing a first error count for each of the plurality of failure modes; storing a total count for each of the plurality of failure modes; incrementing the first error count for a first mode of the plurality of failure modes when the status signals indicate that the first mode has been detected; incrementing the total count for the first mode each time the status signals indicated that the first mode has been analyzed; and setting a fail state for a diagnostic trouble code (DTC) when the first error count for the first mode reaches a first predetermined threshold prior to the total count reaching a second predetermined threshold.
- Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

- Referring now to
FIG. 1 , a functional block diagram of avehicle power system 10 is shown. Thepower system 10 includes anintake system 12, anengine 14, an engine control module (ECM) 16, a spark ignition direct injection (SIDI)fuel system 18, and anexhaust system 20. In theintake system 12, air passing through athrottle valve 22 is drawn into anintake manifold 24. Based on signals from theECM 16, thethrottle valve 22 regulates the volume of air drawn into theintake manifold 24. - The
intake manifold 24 distributes the air toN combustion chambers 26 located in theengine 14. AlthoughFIG. 1 depicts theengine 14 having six combustion chambers 26 (N=6), theengine 14 may include additional orfewer chambers 26. For example only, theengine 14 may include from 1 to 16 chambers. The functions of theECM 16 can be incorporated with functions of a transmission control module (not shown) into a single powertrain control module. - The air in the
combustion chambers 26 combusts with a metered amount of fuel supplied directly to thecombustion chambers 26 by theSIDI fuel system 18. In the SIDIfuel system 18, fuel from afuel tank 28 is pumped to a first pressure (e.g., 0.3-0.6 MegaPascals) by alow pressure pump 30. - The
low pressure pump 30 provides the fuel to ahigh pressure pump 32 that pumps the fuel to a second pressure (e.g., 2-26 MegaPascals). The fuel pressurized to the second pressure is provided tofuel injectors 34 viafuel rails 36 for injection into thecombustion chambers 26. The ECM 16 may vary the output of thefuel injectors 34 to optimize performance of theengine 14. For example, theECM 16 may decrease the amount of fuel injected (leaner air/fuel ratio) at light-load conditions to lower exhaust emission levels. - Conversely, in a full power mode (e.g., during rapid acceleration or with heavy loads), the
ECM 16 may increase the amount of fuel injected (richer air/fuel ratio) to optimize engine performance. While the SIDIfuel system 18 is shown with the singlehigh pressure pump 32 supplying thefuel rails 36, the SIDIfuel system 18 may include any combination of fuel pumps and fuel rails to supply fuel to thefuel injectors 34. For example, in applications having high fuel demands, one or more dedicated fuel pumps may be implemented for each rail in a multiple rail system. The combustion of the air/fuel mixture reciprocally drivespistons 38 located within thecombustion chambers 26 to drive a crankshaft. Power from the crankshaft is used to propel the vehicle. Waste exhaust gases from the combustion process are conveyed away from theengine 14 through theexhaust system 20. - Referring now to
FIG. 2 , a functional block diagram of the engine control module (ECM) 16 is shown including afuel control module 39, aninjector module 40, afuel system module 42, and adiagnostics module 44. Thefuel control module 39 determines a desired air/fuel ratio corresponding to the desired performance characteristics. Thefuel control module 39 converts the desired air/fuel ratio into a desired fuel mass. Theinjector module 40 controls the amount of fuel injected by thefuel injectors 34 to achieve the desired fuel mass. - The
injector module 40 may control the amount of fuel injected by controlling the amount of time that thefuel injectors 34 are open. With a constant fuel pressure in the fuel rails 36, the time that thefuel injectors 34 are open determines the amount of fuel injected. Thefuel system module 42 maintains the fuel pressure in the fuel rails 36 at an approximately constant level. For example only,fuel system module 42 may maintain the fuel pressure to within a predetermined percentage of a desired fuel pressure. - Each of the
fuel injectors 34 may include a low side and a high side input. Theinjector module 40 may therefore include a low-side driver 46 and a high-side driver 48 corresponding to each of thefuel injectors 34. Thedrivers injector module 40 may control the duty cycle of the PWM signals to achieve the desired fuel mass. - The
fuel system module 42 controls asolenoid 50 in thehigh pressure pump 32 using a low-side driver 52 and a high-side driver 54. Thefuel system module 42 receives feedback from afuel rail sensor 56 indicating the fuel pressure in thefuel rail 36. Thedrivers solenoid 50 to allow fuel to flow from thelow pressure pump 30 ofFIG. 1 to afuel line 58. - The
high pressure pump 32 may include a piston-style pump that includes afirst check valve 60, apiston 62, and asecond check valve 64. An end of thepiston 62 is located in achamber 66. Acam 68 presses thepiston 62 from a first position to a second position, which decreases the volume of thechamber 66. Any fuel in thechamber 66 is therefore pushed through thesecond check valve 64 into thefuel line 58. For example only, thecam 68 may be rotated by a valvetrain camshaft (not shown) or by an electric motor (not shown). - The
piston 62 is returned to the second position by a device such as aspring 70. This increases the volume in thechamber 66, thereby lowering the pressure. When thesolenoid 50 is open, the pressure differential in thechamber 66 results in fuel flowing into the chamber from thefirst check valve 60. Amechanical relief valve 71 may allow fuel to flow from thefuel line 58 to the low pressure side of thehigh pressure pump 32 when pressure in thefuel line 58 increases above a threshold. In various implementations, thefuel system module 42 may synchronize the opening and closing of thesolenoid 50 with the position of thecam 68. - Referring now to
FIG. 3 , a schematic diagram of an exemplary implementation of thedrivers side driver switch 72 selectively allows current to flow from aload 74 to a low potential, such as ground or 12 V. In the high-side driver switch 73 selectively allows current to flow from a power supply to theload 74. In various implementations, a voltage of the power supply may be varied, such as by selecting one of two power supply voltages. In various implementations, the two power supply voltages may be 12 V and 65 V. In various implementations, theswitches - The
load 74 connects to the high-side driver side driver load 74 is driven by both the high-side driver side driver side drivers side drivers load 74. Therefore, each pair of high and low-side drivers may evidence at least seven failure modes. - Referring now to
FIG. 4A , an exemplary implementation of thediagnostics module 44 is shown. Theinjector module 40 determines when one of the above failure modes is present in any of the low-side drivers 46 or the high-side drivers 48. Thefuel system module 42 determines when one of the above failure modes is present in the low-side driver 52 or the high-side driver 54. For example only, theinjector module 40 may measure currents and/or voltages at various locations of the low-side driver 46 and the high-side driver 48 of one of thefuel injectors 34 in order to detect various failure modes. - The
diagnostics module 44 records data pertaining to the detected failure modes, analyzes the recorded data, and makes PASS/FAIL decisions based on the analysis. For example only, thediagnostics module 44 includes aparsing module 75, astorage module 76, acomparison module 78, acalibration module 80, aremedial action module 82, and atimer module 84. Theparsing module 75 receives status signals from theinjector module 40 and thefuel system module 42 indicating which failures have been detected and/or whether no failures have been detected. - For example only, seven failure modes may be defined for each low/high-side driver pair, as described above and shown in
FIG. 4B . Although seven failure modes are shown, some or all of the low/high-side driver pairs may have more or fewer failure modes defined. When sixfuel injectors 34 are present, such as for a six-cylinder engine, and a pump solenoid is controlled with a low/high-side driver pair, there are 7 total low/high-side driver pairs. Therefore, 49 failure modes may be recorded—7 failure modes for each of the 7 driver pairs. - Referring now to
FIG. 4B , an exemplary storage table 86 stored in thestorage module 76 is shown. Each storage location of the storage table 86 may correspond to one of the failure modes being detected for one of the low/high-side driver pairs. Each storage location may include two values, named X and Y. The X value tracks the number of times a failure mode was detected, while the Y value tracks the total number of detection cycles. In other implementations, each storage location includes an X value, while one or more common Y values are stored. For example, a single Y value may be stored for the entire storage table 86. Alternatively, different Y values may be stored for each failure mode, with each Y value being common across all of the low/high-side driver pairs for that failure mode. - In various implementations, whether a given failure mode is present for a given low/high-side driver pair may be determined periodically, such as every 12.5 ms, every 62.5 ms, or every 100 ms. The period between determinations may be different for each low/high-side driver pair and each failure mode. For purposes of illustration, refer to a
storage location 88 for a failure mode of the low side output (LSO) being open for fuel injector C. The values instorage location 88 indicate that 40 faults have been detected (X=40) in 100 detection cycles (Y=100). In other words, the LSO open failure mode was detected in 40% of the 100 detection cycles. Shown as further illustration, injector A had an LSO open failure mode for 100% of the last 40 detection cycles, while injector E had an LSO open failure mode for 20% of the last 50 detection cycles. - Referring back to
FIG. 4A , thetimer module 84 may determine how often failure mode data is read by the parsingmodule 75. Thetimer module 84 may provide different timing signals for different failure modes depending on how often checks are performed for presence of the respective failure modes. Each time theparsing module 75 receives an indication of whether or not a failure mode is present, the parsingmodule 75 increments the Y value in the corresponding storage location of thestorage module 76. If the failure mode was present, the parsingmodule 75 increments the X value in the corresponding storage location of thestorage module 76. - The
comparison module 78 analyzes the data stored in thestorage module 76. For example only, thecomparison module 78 may compare the X and Y values of each storage location to predetermined thresholds. These thresholds may be stored in acalibration module 80 and may be set independently for each failure mode and each low/high-side driver pair. In various implementations, the thresholds for a given failure mode may be set equal for all low/high-side driver pairs. - For example only, a selected storage location may have a first predetermined threshold for the X value and a second predetermined threshold for the Y value. When the Y value of a storage location reaches the second predetermined threshold, the
comparison module 78 may reset the X and Y values in the storage location to 0. However, when the Y value has not yet reached the second predetermined threshold but the X value reaches the first predetermined threshold, thecomparison module 78 may set a diagnostic trouble code (DTC). The DTC is transmitted to theremedial action module 82. - As an illustration, consider a case where the first predetermined threshold is 40 and the second predetermined threshold is 100. This corresponds to a 40% threshold, above which a DTC will be set. If the Y value reaches 100 before the X value reaches 40, the percentage of failure mode detection will be less than 40%. The DTC is set to a pass state, and both X and Y are reset for another series of measurements. However, if the X values reaches 40 at any time up to and including when the Y value reaches 100, the percentage of failure mode detection is 40% or greater. The DTC is set to a fail state, and both X and Y are reset for another series of measurements.
- Separate DTCs may be assigned to each failure mode for each low/high-side driver pair. The
remedial action module 82 may record the total number of each DTC generated by thecomparison module 78. Theremedial action module 82 may also record information about when the DTCs were generated. Theremedial action module 82 may provide this stored information to diagnostic devices, such as OBD-II scan tools. - Further, the
remedial action module 82 may provide feedback to an operator of the vehicle, such as by illuminating an indicator light or outputting a message to a display. Further, theremedial action module 82 may instruct vehicle systems to perform various remedial actions. For example only, the remedial actions selected may be based on which type and how many of the DTCs are received. - The
remedial action module 82 may reduce the upper limit of power output of the engine. Theremedial action module 82 may reduce the maximum allowed air/fuel mixture richness (equivalent to increasing the lower limit on air/fuel ratio). Theremedial action module 82 may limit the opening of thethrottle valve 22 to a range of positions or to a predetermined position. Theremedial action module 82 may halt the provision of fuel to one ormore cylinders 38. Theremedial action module 82 may shutdown theengine 14, which may include halting provision of fuel to all of thecylinders 38 and/or stopping the provision of spark to all of thecylinders 38. - Referring now to
FIG. 5 , a flowchart depicts exemplary operation of thediagnostics module 44 ofFIG. 4A . Control may begin when theengine 14 is started. Control begins instep 102, where control clears the X and Y values for each of the storage locations in thestorage module 76. Control continues instep 104, where control receives fault information from thefuel system module 42 and theinjector module 40. - Control continues in
step 106, where control determines whether a timer signal has been generated by thetimer module 84. If so, control transfers to step 108; otherwise, control returns to step 104. The timer signal received instep 106 may correspond to one or more of the storage locations of thestorage module 76. - For example only, all failure modes for all low/high-side driver pairs are determined on a common periodic schedule. In this case, the timer signal in
step 106 indicates that the X and Y values will be updated for all storage locations in thestorage module 76. Alternatively, the timer signal may apply to only certain failure modes. For example only, failure modes that are tested more frequently may correspond to a timer signal that is generated more often. For example only, shorts to ground and to power may be tested more frequently than open failure modes. - In step 108, control selectively increments X and Y values for storage locations that correspond to the timer signal generated in
step 106. The Y values for each of the storage locations may be incremented regardless of whether a fault was detected, while the X values may be incremented when the corresponding failure mode of the corresponding low/high-side driver pair is detected. - Control continues in
step 110, where control determines whether an X value of any of the updated storage locations is greater than a corresponding predetermined threshold. If the X value exceeds the corresponding threshold for one or more of the storage locations, control transfers to step 112; otherwise, control transfers to step 114. - The predetermined threshold may be stored by a
calibration module 80. As described above, the thresholds may be different depending on the failure mode and the low/high-side driver pair to which the storage location applies. In various implementations, thecalibration module 80 may include a table similar to the storage table 86, where the X and Y values in each storage location indicate the X and Y thresholds to apply to the storage table 86. - In
step 114, control determines whether the Y value for any of the storage locations updated in step 108 is greater than a corresponding predetermined threshold. If so, control transfers to step 116; otherwise, control returns to step 104. The Y thresholds may also be stored by thecalibration module 80. In various implementations, the inequality insteps step 116, control reports a pass state for a diagnostic trouble code (DTC) to theremedial action module 82. The DTC corresponds to the storage location identified instep 114 for which the Y value is greater than the predetermined threshold. - Control continues in
step 118, where remedial action is selectively halted. For example, if remedial action had been initiated based on the DTC that now has a pass state, the remedial action may be halted. Alternatively, the previous remedial action may be made less restrictive. For example only, an upper torque limit may be increased when the DTC previously having a fail state now has the pass state. Control continues instep 120, control resets the X and Y values for the identified storage location and control returns to step 104. - In
step 112, control reports a fail state for a diagnostic trouble code (DTC) to theremedial action module 82. The DTC corresponds to the storage location identified instep 110 for which the X value is greater than the predetermined threshold. When multiple storage locations meet the criteria instep 110, multiple fail state DTCs may be reported to the remedialaction module step 112. Distinct DTCs may be defined for each storage location in the storage table 86. - Control continues in
step 122, where control selectively performs predetermined remedial actions based upon the DTCs sent instep 112. Whether remedial action is performed and which remedial action or actions will be performed instep 122 may further be determined by previous DTC information. - For example only, a first DTC for a first low/high-side driver pair corresponding to a first fuel injector, where the failure mode is a low-side output (LSO) open failure, may be logged for retrieval by a service technician. However, additional instances of the same DTC may trigger deactivation of the first fuel injector. Deactivating the fuel injector may include deactivating the associated cylinder and any other fuel injectors serving the associated cylinder.
- For example only, the selected remedial action may include shutting down the
engine 14 when a summation of DTCs across multiple fuel injectors is greater than a threshold number. After performing and/or initiating the predetermined remedial action, control continues instep 120, where the X and Y values for the storage locations identified instep 110 are reset. - The broad teachings of the disclosure can be implemented in a variety of forms. Therefore, while this disclosure includes particular examples, the true scope of the disclosure should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, the specification, and the following claims.
