Embodiment
Hereinafter, with reference to accompanying drawing, will describe according to example embodiment of the present invention now and be applied to the control apparatus of vehicle-mounted automotive engine system.
Fig. 1 illustrates the configuration of the vehicle-mounted automotive engine system according to the present embodiment.
As shown in Figure 1, vehicle-mounted automotive engine system is provided with the starting arrangement started the engine 42 installed on a vehicle.Starting arrangement 10 comprises small gear (pinion) 12, for promoting the electromagnetic drive type actuator 14 of small gear 12 and the motor 16 for driving pinion 12 rotatably.The promotion of small gear 12 drives operation and rotary actuation operation to be executable respectively.Particularly, by battery 18 drive motor 16 being rotatably used as power supply.ICR relay 20 (correspond to and reduce unit according to the inrush current of the present embodiment) and switch (hereinafter referred to as " SL (solenoid, solenoid) 2 switch 22) be arranged between motor 16 and battery 18.SL2 switch 22 switches between the energising and going of motor 16 is energized.Especially, the ICR relay 20 be connected in series and SL2 switch 22 be arranged in be connected battery 18 and motor 16 power path on.SL2 switch 22 is connected to the SL2 switched on and off by SL2 switch 22 and drives relay 24.
ICR relay 20 comprises being connected in parallel of resistor 20a and relay (short-circuit relay 20b), and reduces the inrush current flow through in motor 16 when starting arrangement starts, fully electric power is fed to motor 16 from battery 18.Particularly, when starting arrangement 10 starts, disconnect short-circuit relay 20b, then via resistance component 20a, the electric power of battery 18 is fed to motor 16.So, carried out the inrush current flow through in restrictions motor 16 by resistor 20a, so the inrush current flow through in motor 16 can be reduced.Then, so that the mode of battery 18 and starting arrangement 16 short circuit is connected short-circuit relay 20b, so fully electric power can be fed to motor 16 from battery 18.
In the present embodiment, normally closed type is used as short-circuit relay 20b, its energising respectively by the coil of short-circuit relay 20b and go energising to switch on and off.If the exception that certain factor can cause short-circuit relay 20b to connect, be then fed to motor 16 from battery 18 via resistor 20a when starting arrangement 10 starts current continuity.Therefore, resistor 20a can be destroyed by heat, so starting arrangement 10 cannot start.Due to this, normally closed type is used as short-circuit relay 20b, enables the state that short-circuit relay 20b keeps wherein as much as possible except the starting of starting arrangement 10.Therefore, this can guarantee the supply path from battery 18 to motor 16, thus the situation that minimizing starting arrangement 10 cannot drive.
In addition, SL2 switch 22 is configured to drive relay 24 to switch on and off by SL2.This configuration makes SL2 switch 22 can be switched on and off by the instruction from electronic control unit described below (hereinafter referred to as " ECU 26 ", it corresponds to the control apparatus for starting drive according to the present embodiment).Because electric current very large when motor 16 runs flows through in SL2 switch 22, so switch on and off the ER effect large (such as, some amperes [A]) required for SL2 switch 22.But, due to little electric current (such as, hundreds of milliampere [mA]) only can be supplied from ECU 26 as its command signal, so ECU 26 is difficult to direct control SL2 switch 22.Herein, SL drives relay 24 in current capacity, be less than SL2 switch 22, so can drive relay 24 by the electric current less than the electric current switched on and off required for SL2 switch to switch on and off SL.SL2 driving relay 24 is switched on and off, to switch on and off SL2 switch, so switch on and off SL2 switch 22 based on these instructions from ECU 26 based on the instruction that switches on and off from ECU 26.
Drive actuator 14 is carried out by the battery 18 as power supply.SL1 drives relay 28 to be connected between actuator 14 and battery 18.SL1 relay switches between the energising and going of actuator 14 is energized.
When being operated ignition switch (ignition key) 30 rotatably by driver's (vehicle operator), also electric power is fed to motor 16 and actuator 14 from battery 18.Particularly, SL2 switch 22 is also provided with SL2 and initially drives relay 32 except SL drives 24, and relay 32 initially can be driven to switch on and off SL2 switch 22 by SL2.Switch on and off SL2 by starting drive switch 36, neutral position switch 38 and delay circuit 40 and initially drive relay 32.Starting drive switch 36 is switched on and off by the rotation process of ignition switch 30.When the drive range of transmission device unshowned in Fig. 1 shifts gears N (neutral) or P (parking) scope etc., connect neutral position switch 38.Except SL1 drives relay 28, between battery 18 and actuator 14, also arrange that SL1 initially drives relay 34.Switch on and off SL1 by starting arrangement 36 and neutral position switch 38 and initially drive relay 34.
In such an arrangement, when connect SL1 drive relay 28 and SL1 initially to drive relay 34, be then energized by battery 18 pairs of actuators 14 time, small gear 12 is advanced to the ring gear 46 of the output shaft of engine 42 (bent axle 44) mechanical coupling, is then meshed with ring gear 46.When connecting SL2 and driving relay 24 or SL2 initially to drive relay 32 to connect SL2 switch 22, when being then energized by battery 18 pairs of motor 16, operating small gear 12 rotatably, thus give bent axle 44 (performing shake) by initially rotating.
Above system is equipped with the such as apparatus of air conditioning 48 or power steering apparatus 50.The apparatus of air conditioning 48 performs the air conditioning in car, and the turning to of power steering apparatus 50 driver assistance.
Fig. 7 illustrates the configuration of the microcomputer 260 (correspond to the change processing unit according to the present embodiment, acquiring unit, diagnosis unit, automatically start-stop control unit, exception processing unit and forbid processing unit) be included in ECU 26.
As shown in Figure 7, ECU 26 forms primarily of the microcomputer 260 that battery 18 is used as power supply, wherein, microcomputer 260 comprises known CPU (central processing unit) 261, ROM (ROM (read-only memory)) 262 and RAM (random access storage device) 263.ECU 26 receives the output signal from such as voltage transducer 52, current sensor 54 and air conditioning deploy switch 56.Voltage transducer 52 and current sensor 54 detect the voltage and current in battery 18 respectively.Driver is used for the car internal object temperature of air conditioning control and the mode of air quantity with setting, operates air conditioning deploy switch 56.ECU 26 performs the various control programs be stored in ROM 262, to perform the process comprising the following based on above input: stop control treatment and the drived control process to starting arrangement 10 to the air conditioning control treatment of the apparatus of air conditioning 48, the control treatment to power steering apparatus 50, reset processing, free time.
In fact each in the apparatus of air conditioning 48, power steering apparatus 50 and automotive engine system etc. operated by independent electronic control unit.In the present embodiment, these electronic control units are represented by ECU 26.
Reset processing is such process: if the cell voltage calculated based on the output value of voltage transducer 52 is lower than required voltage (such as 6V), then perform the process emptying data and the reset microcomputer 260 stored in RAM 263.The object of this process is the situation that the various controls reducing the traffic tool cannot suitably perform.ECU 26 obtains the checkout value from various sensor, is stored in RAM 263 by these checkout values temporarily, and performs various control based on these checkout values stored.If the operation causing due to the voltage drop etc. of the battery 18 that is used as power supply guaranteeing microcomputer or the reliability of checkout value stored reduce, then cannot suitably perform various control.Due to this, perform reset processing is used as the traffic tool data required for various controls with the default value will stored in ROM 262, and again desired data are stored in RAM263, the situation that these various controls reducing the traffic tool cannot suitably perform.
Idle stopping control treatment is such process: if meet predetermined stop condition, then stopping fuel oil injection etc. are automatically to stop engine, if and meet predetermined restarting condition subsequently, then start the drived control of starting arrangement 10 and fuel oil injection etc. so that restarting engine automatically.The logical produc that stop condition can be condition is genuine condition, and its conditional comprises and performs the condition of brake operating and the travelling speed of the traffic tool lower than the second condition of predetermined speed being greater than zero.Restarting condition can be the condition of release brake operating.
The drived control process of starting arrangement 10 drives relay 28 and SL2 to drive the power-on servicing of relay 24 to perform the process of shake by short-circuit relay 20b, SL1.Herein, with reference to figure 2, above drived control will be described.Particularly, Fig. 2 (a) illustrates the change of the battery current I of the output value based on current sensor 54, Fig. 2 (b) illustrates the change of the drive condition of short-circuit relay 20b, and Fig. 2 (c) illustrates the change of the drive condition of SL2 switch 22.
As shown in Figure 2, first, at time t1, in order to reduce the inrush current when starting arrangement 10 starts, open command for short-circuit relay 20b is exported to disconnect short-circuit relay 20b (with reference to figure 3A) from ECU 26.Subsequently, at time t2, connect SL and drive relay 24 and then connect SL2 switch 22, to be energized to motor 16.With the situation of battery 18 with motor 16 short circuit being compared as shown in the dotted line of Fig. 2 (a), this can reduce the inrush current flow through in motor 16 as shown in the solid line of Fig. 2 (a).
Then, at time t3, connect short-circuit relay 20b by from going code of ECU 26, then battery 18 and motor 16 short circuit are fed to motor 16 (see Fig. 3 B) fully to enable electric current.Particularly, rectification is carried out to the electric current being fed to motor 16, to become the value can guaranteeing the generation moment of torsion of motor 16 required for shake.Subsequently, at time t4, if ECU26 judges the speed causing the rotational speed of engine higher than definition due to shake, then disconnect SL2 switch to complete the control treatment to starting arrangement 10.
Herein, the drived control when engine 42 starts (initial start) to starting arrangement 10 caused due to the operation of ignition switch 30 will be described.First, by the operation of driver, ignition switch 30 is moved to ACC or on positi rotatably, then disconnect short-circuit relay 20b.Subsequently, ignition switch 30 is moved to starting position rotatably, then connect starting arrangement switch 36.When connecting starting arrangement switch 36, connecting the initial driving switch 34 of SL1, then electric power being fed to actuator 14 from battery 18.Then, after the delay of the scheduled time caused due to delay circuit 40, connect SL2 initially drive relay 32, then connect SL2 switch 22 to be energized from battery 18 pairs of motor 16, this makes it possible to perform shake.
When switching on and off short-circuit relay 20b, produce electrical spark.Due to electrical spark etc., the adhesion that the switch 20b that can be short-circuited in ICR relay 20 cannot switch on and off is abnormal.In this case, inconvenience below can be caused.Such as, if above abnormal " open failure " causing short-circuit relay 20b, then, as shown in the dot and dash line of Fig. 2 (a), when shaking, electric current is limited by resistor 20a, so resistor 20a can be, usually, thermically destroyed.In this case, starting arrangement 10 cannot be driven, so engine 42 cannot be started.
On the other hand, if above abnormal " the connection fault " causing short-circuit relay 20b, then, as shown in the dotted line of Fig. 2 (a), the inrush current flow through in motor 16 when cannot reduce shake, so the voltage of battery 18 can decline.Therefore, reset processing can be performed.In this case, the drived control process and fuel Injection Control etc. to starting arrangement 10 is stopped.Due to this, completing of the starting of engine 42 can be postponed.In addition, when performing reset processing, the air conditioning configuration information of the such as air quantity and target temperature that are set by air conditioning deploy switch 56 by driver becomes default value, so driver can be bothered by input air regulating allocation information again.
In the present embodiment, can control be stopped automatically stopping engine 42 by the free time while the traffic tool just movement, and starting arrangement 10 can be started, so as while the traffic tool just movement restarting engine 42.In this case, due to the decline of cell voltage, perform reset processing, so inconvenience below can be caused.When performing reset processing, stop the control to power steering apparatus 50, so the actuator of the electric action type of this equipment 50 suitably cannot be operated.Therefore, operation the traffic tool while, power steering apparatus 50 cannot suitably assisted diversion wheel operational capacity.
In order to address these problems, in the present embodiment, when the open command of the short-circuit relay 10 when starting arrangement 10 starts is changed into and is gone code, ECU 26 execute exception diagnostic process is to diagnose the presence or absence of the exception of ICR relay 20 based on the knots modification of battery current, if then diagnosis exists abnormal, also perform notifier processes with by this result driver.Which reduce the situation using starting arrangement to there is abnormal state in ICR relay 20 under continuously.Hereinafter, the abnormity diagnosis process to ICR relay 20 will be described in detail.
Fig. 4 illustrates the abnormity diagnosis technology according to the present embodiment.Particularly, Fig. 4 (a) and Fig. 4 (c) corresponds respectively to Fig. 2 (a) and Fig. 2 (b), and Fig. 4 (b) illustrates the knots modification Δ I of battery current.Here, as shown in Fig. 4 (c), Δ I is the knots modification of battery current relative to predetermined amount of time Δ t (such as some milliseconds).
As shown in Figure 4, at time t1, from the open command of ECU 26 output short-circuit relay 20b, subsequently at time t3, when by ECU 26 by for short-circuit relay 20b open command change become go code time, if ECU 26 judges that the knots modification Δ I of battery current is greater than specified value α (Δ I > α), then ECU 26 judges exception not to occur in ICR relay 20.On the contrary, if ECU26 judges that the knots modification Δ I of battery current is specified value α or less (Δ I≤α), then ECU 26 judges to occur abnormal (" connection fault " or " open failure ") in ICR relay 20.This considers following true diagnostic techniques: if occur to adhere to abnormal in short-circuit relay 20b, then when open command change over go code time ICR relay 20 resistance value without change.Specified value α can be preset based on such as test result.
Here, in abnormity diagnosis operation, the knots modification Δ I of battery current is used because of reason below.If the temperature change of battery 18 or battery 18 time to time change, then as shown in Figure 3 A and Figure 3 B, the internal resistance of battery 18 changes, so relative to electric power Vo, cell voltage (terminal voltage) Vb can change.In this case, when open command change over go code time, the knots modification of cell voltage Vb changes.Due to this, cannot set and be suitable for determining whether abnormal specified value α occurs in ICR relay 20, degenerate so can make whether abnormal degree of accuracy occurs in diagnosis ICR relay 20.According to this, be not the knots modification of cell voltage but the knots modification of battery current for preventing above inconvenience.
The traffic tool are generally equipped with the current sensor 45 for the state of monitoring battery 18, so the traffic tool do not need to be equipped with the new sensor for abnormity diagnosis process.
Fig. 5 diagram is according to the step of the abnormity diagnosis process of ICR relay 20 of the present invention.This processing example is as performed with the predetermined cycle by ECU 26.Fig. 8 illustrates the functional configuration of the microcomputer 260 of the ECU 26 of execute exception diagnostic process.In the example of fig. 8, microcomputer 260 comprises abnormity diagnosis unit 100 (corresponding to the diagnosis unit according to the present embodiment) and Δ I acquiring unit 200 (corresponding to the acquiring unit according to the present embodiment).Abnormity diagnosis unit 100 comprises diagnostic markers F2 in abnormity diagnosis mark F1 judging unit 110, diagnosis executive condition judging unit 112, execution (hereinafter referred to as " diagnosis execute flag F2 ") judging unit 114, first and diagnoses execute flag F2 setup unit 116, Δ I judging unit 118, second opinion execute flag F2 setup unit 120, abnormity diagnosis mark F1 setup unit 122 and notice and IS to forbid processing unit 124.
In process sequence, in step S10, ECU 26 judges whether the value of abnormity diagnosis mark F1 is that " 0 " (this processing response is in predetermined beginning control signal S100, this starts control signal S100 for timing controlling in the process sequence that generated with predetermined period by ECU 26, and such as abnormity diagnosis mark F1 judging unit 110 as shown in Figure 8 performs this process).Here, the value of abnormity diagnosis mark F1 is " 0 " and " 1 ", wherein exception does not occur in " 0 " expression ICR relay 20, and " 1 " represents that in ICR relay 20, generation is abnormal.The value of this abnormity diagnosis mark F1 is stored in the nonvolatile memory of EEPROM (electric erasable and programmable read only memory) of such as ECU 26, and its initial value is set to " 0 ".
In step S10, if ECU 26 judges that the value of abnormity diagnosis mark F1 is as " 0 " (YES), then ECU 26 proceeds to the process performing step S12, to judge whether to meet diagnosis executive condition (this processing example diagnosis executive condition as illustrated by fig.8 judges that judging unit 112 performs).In the present embodiment, diagnosis executive condition is the logic of condition and is genuine condition, and wherein, condition comprises the condition of the initial start that there is engine 42 and meets the condition of restarting condition.Can based on the operational condition of ignition switch 30 to the judgement that whether there is the initial start of engine 42.
In step S12, if ECU 26 judges to meet diagnosis executive condition (YES), then ECU 26 proceeds to the process performing step S14, to judge whether diagnosis execute flag F2 is " 0 " (this processing example diagnosis execute flag F2 judging unit 114 as illustrated by fig.8 performs).The object of this process is, even if when performing the abnormity diagnosis process to short-circuit relay 20b, perform reset processing due to " the connection fault " of short-circuit relay 20b, when then stopping abnormity diagnosis process, also suitably takes action subsequently.Here, the value of diagnosis execute flag F2 is " 0 " and " 1 ", and wherein " 0 " represents also non-execute exception diagnostic process, and " 1 " represents abnormity diagnosis process in commission.The value of diagnosis execute flag F2 is stored in the nonvolatile memory of the EEPROM of such as ECU 26, and its initial value is set to " 0 ".
In step S14, if ECU 26 judges that diagnosis execute flag F2 is as " 0 " (YES), then ECU 26 proceeds to the process performing step S16, the value of diagnosis execute flag F2 to be set as " 1 " (this processing example the first diagnosis execute flag F2 setup unit 116 as illustrated by fig.8 performs).
Subsequently, in step S18, when ECU 26 open command changed over go code time, ECU26 judges whether the knots modification Δ I of battery current is greater than specified value α (Δ I > α) (this processing example Δ I judging unit 118 as illustrated by fig.8 performs).Amount to obtain Δ I is carried out based on the value I of the battery current detected by current sensor 54 by the Δ I acquiring unit 200 shown in Fig. 8.
In step S18, if ECU 26 judges that the knots modification Δ I in battery current is greater than specified value α (Δ I > α) (YES), then ECU 26 diagnoses in ICR relay 20 and exception does not occur, and then in step S20, the value of diagnosis execute flag F2 is set as " 0 " (this processing example such as second opinion execute flag F2 setup unit 120 as shown in by Fig. 8 performs).
On the contrary, in step S18, if ECU 26 judges that the knots modification Δ I of battery current is specified value α or less (Δ I≤α) (no), then ECU 26 judges to occur extremely in ICR relay 20, then in step S22, the value of diagnosis execute flag F2 is set to " 1 " (this processing example such as abnormity diagnosis mark F1 setup unit 122 as shown in by Fig. 8 performs).
If ECU 26 is judged as NO in step S10 or S14, or the process of completing steps S22, then ECU 26 proceeds to and performs the process of step S24, i.e. notifier processes and forbid the idle process (IS forbids processing) (this processing example such as the notice as shown in by Fig. 8 and IS forbid that processing unit 124 performs) stopping controlling.The object of these process is the situations preventing from occurring to use starting arrangement 10 in abnormal state continuously in ICR relay 20.Here, notifier processes such as can be opens stand by lamp or by this result of sound notification, and IS forbids that processing example forbids the self-braking subsequently process (such as, forbidding that processing unit 124 exports for controlling the control signal notifying to forbid with IS processing from abnormity diagnosis unit 100 via notice and IS) of engine 42 as can be.
The value of abnormity diagnosis mark F1 and diagnosis execute flag F2 such as can be repaired at repairing factory, is then configured to " 0 ".
If ECU 26 is judged as NO in step S10, S12 or S14, or the process of completing steps S20 or S24, then complete process sequence (such as, relevant therewith settling signal S110 exports from abnormity diagnosis unit 100 via the corresponding unit shown in Fig. 8).
In the present embodiment described above in detail, obtain effect below.
