Again, the inner structure of vehicle electronic device 1a is as described below.
10 comprise not shown various memory devices etc. and as the microprocessor of the 1st control device of a plurality of signals of input and output, the 11st, microprocessor 10 is supplied with static power source P1, action power P2, power subsystem units such as the on/off signal input SW of source switch 4, the 12nd, as when microprocessor 10 regular events, obtaining periodically to produce the monitor signal WD of on/off pulse, when stopping to move, monitor signal WD produces the watchdog timer (WDT) of the supervision means of reset pulse output RST2,12a is the one-shot timer (on shot timer) that produces reset pulse output RST when action power P2 rises, 12b is logic and element, and reset pulse is exported RST1 for this logic and element 12b or resetting of RST2 supply microprocessor 10 imported RST and carried out the initialization of microprocessor 10 thus, reset.
13a is the transistor to magnet coil 5b energising, 13b is the 1st driving resistor that obtains power supply and driving transistors 13a from Vehicular accumulator cell 2 by source switch 4,13c is by the control output O1 power supply of microprocessor 10 and the 2nd driving resistor of driving transistors 13a, 13b is the emitter that is connected transistor 13a, the steady resistance between the base stage, also continues to produce the delay output means of output as described later even control output O1 becomes in fact when source switch 4 open circuits.
14a is the transistor to magnet coil 7b energising, and 14b is that 14c is the emitter that is connected transistor 14a, the steady resistance between the base stage by the control output O2 power supply of microprocessor 10 and the driving resistor of driving transistors 14a.
15a is the transistor that drives the 1st vehicle-mounted load 6a, and 15b is that 15c is the emitter that is connected transistor 15a, the steady resistance between the base stage by the control output O3 power supply of microprocessor 10 and the driving resistor of driving transistors 15a.
16a is as the memory element of the storage means that resetted by reset pulse output RST2, constitute with trigger circuit, 16b is the output halt circuit that stops means as output, 16c supplies with the also display lamp of driving transistors 16d by the storage output of memory element 16a, 16e is the emitter that is connected transistor 16d, the steady resistance between the base stage, output halt circuit 16b is made of display lamp 16c, transistor 16d, steady resistance 16e, and display lamp 16c becomes the abnormality alarm device as abnormality alarm means from memory element 16a action to the driver that notify.
Again, the 17th, change to the decline detecting element of the open circuited means that reset as detecting source switch 4 from connection, structure resets memory element 16a according to the output of this decline detecting element 17.
18a is the transistor that drives the 3rd vehicle-mounted load 6b, and 18b is that 18c is the emitter that is connected transistor 18a, the steady resistance between the base stage by the control output O4 power supply of microprocessor 10 and the driving resistor of driving transistors 18a.
20a, 20b, 20c optionally connect the base terminal of transistor 14a, 18a, 15a and the diode between the transistor 16d collector terminal, not necessarily transistor 16d will be connected with all transistor 14a, 18a, 15a.
Secondly, the action for it describes with reference to the sequential chart of Fig. 2~Fig. 3.Again, in each figure, the convex side of waveform is represented switch or transistor connection, or produces the situation of output voltage.
At first, describe for the situation of microprocessor 10 regular events with reference to Fig. 2.
The on/off waveform of Fig. 2 (a) expression source switch 4, the output wave shape of Fig. 2 (b) expression one-shot timer 12a, the output that this output wave shape and source switch 4 produce specified time Td1 linkedly from the action that is disconnected to connection, it is equivalent to the reset pulse output RST1 of Fig. 2 (c).
Fig. 2 (d) is the waveform of the monitor signal WD of microprocessor 10 generations, microprocessor 10 is beginning to disconnect the pulse that produces some cycles up to the action power P2 of microprocessor 10 from the pulse output RST1 initialization that is reset, under this state, can not produce the reset pulse output RST2 shown in Fig. 2 (e).
Fig. 2 (f) is the output wave shape of the control output O1 of microprocessor 10, and microprocessor 10 is producing output from the pulse output RST2 initialisation that is reset, and has disconnected at source switch 4 and only to postpone delay time Td2 and then stop to export.
Again, exist in vehicle-mounted load in the time of must will recovering the exiter of initial position, delay time, Td2 then became up to the time of finishing this initial position recovery action.
The action of Fig. 2 (g), (h) expression power supply relay 5 and with respect to the supply condition of microprocessor 10 action power P2, they move along with inserting source switch 4, and along with control stopping of O1 of output and stop action.
The action of Fig. 2 (i), (j) expression display lamp 16c and output halt circuit 16b is not because the reset pulse of Fig. 2 (e) output RST2 once have generation, so Fig. 2 (i), (j) are failure to actuate.
Secondly, describe for the situation that microprocessor 10 produces anomalous behavior with reference to Fig. 3.
The on/off waveform of Fig. 3 (a) expression source switch 4, the output wave shape of Fig. 3 (b) expression one-shot timer 12a, the output that produces certain time interval T d1 linkedly from the action that is disconnected to conducting of this output wave shape and source switch 4, it is equivalent to the reset pulse output RST1 of Fig. 3 (c).
Fig. 3 (d) expression microprocessor 10 produces the waveform of monitor signal WD, and microprocessor 10 produces periodic pulse soon after by reset pulse output RST1 initialization.
Yet when waiting this monitor signal to stop because of the noise error action, watchdog timer 12 moves, and only produces reset pulse output RST2 at certain time interval T r shown in Fig. 3 (e).
Fig. 3 (f) is the output wave shape of the control output O1 of microprocessor 10, microprocessor 10 produces output after by reset pulse output RST1 initialization, after disconnecting, source switch 4 only postpones Td2 and stop to export delay time, such situation is normal, stops but exporting during reset pulse output RST2 action.
The action of Fig. 3 (g), (h) expression power supply relay 5 and the state that action power P2 powers to microprocessor 10, they move along with inserting source switch 4, are failure to actuate along with control stopping of O1 of output.
Yet, reset pulse output RST2 action and control output O1 stop during in because source switch 4 is still connected, so power supply relay 5 continues to move, therefore, action power P2 does not stop to move yet.
The action of Fig. 3 (i), (j) expression display lamp 16c and output halt circuit 16b, they move when the reset pulse output RST2 of Fig. 3 (e) produces and are resetted by detecting element 17 when source switch 4 disconnects.
Again, can be by reclosing the action that source switch 4 comes resets memory elements 16a, and this moment as Fig. 3 (i), (j) as shown in abnormal indication lamp 16c and stop output circuit 16b and between delay time Td2, also continue to move, also stop output for the exiter that must will return to initial position, so can not recover initial position in the same old way.
Therefore, as mentioned above,, then, the disconnection along with source switch 4 can not move, so can recover initial position between Td2 in delay time owing to stopping output circuit if come the action of resets memory elements 16a in advance by the disconnection of source switch 4.
Moreover when stopping output circuit 16b action, the load driving of diode 20a, the 20b of connection diagram 1, the part of 20c is failure to actuate with transistor (driver element).
So, in this example, the monitor signal of monitor microprocessors is set and when the microprocessor remarkable action, produces reset pulse output and reset the watchdog timer of microprocessor, stop to be arranged on the output halt circuit of the action of the load-relay on the feed circuit of load linkedly with the action of the memory element of the generation of storage reset pulse output, and, textural because memory element when source switch disconnects or when reclosing be reset, so produce when out of control at microprocessor, can reset immediately and try and reset, simultaneously, when having misoperation, only force to stop its action for unaccommodated load, by disconnecting power switch or access again, can remove and force to stop.
Again, in the vehicle electronic device of microprocessor is housed, power by the power supply relay of action when the M/C source switch of ignition lock etc. is connected by Vehicular accumulator cell, this power supply relay disconnects the back till the part of vehicle-mounted load returns to primary position and continue action at source switch, again, because the output halt circuit is set, the action of the memory element that the reset pulse that this output halt circuit and storage produce with respect to microprocessor is exported stops to be arranged on the action of the load-relay on the electric circuit linkedly, so memory element is reset when source switch disconnects, thus, even exist under the situation of the load that is forced to stop, when disconnecting power switch and shutting engine down, can remove and force to stop, and exiter can carry out initial position recovery action.
Example 2
Fig. 4 represents the constructional drawing of the invention process form 2.Again, in Fig. 4, for adopting identical symbol and detailed with the corresponding part of Fig. 1.
In the figure, 10b receives static power source P1, the supply of action power P2 and the secondary microprocessor that moves, and the monitor signal WDo of this pair microprocessor 10b supplies with the supervision input WDi of microprocessor 10a.If monitor signal WDo when stopping microprocessor 10a produce reset pulse output 05 and the input RSTi that resets by secondary microprocessor 10b resets secondary microprocessor 10b.
Again, in fact, logic from RST2 to the input RSTi that resets of secondary microprocessor 10b that supply with reset pulse output RST1 and with.
The 8th, by the output contact 7a and the 2nd vehicle-mounted load of Vehicular accumulator cell 2 bonded assemblys of load-relay 7,19a is the transistor that drives the second vehicle-mounted load 8,19b is that 19c is connected the emitter of transistor 19a, the steady resistance between the base stage by the control output O6 power supply of secondary microprocessor 10b and the driving resistor of driving transistors 19a.
16f has up-counter input UP to reset with currency and import the counting machine of RS, this counting machine 16f is for the reset pulse output RST2 that is input to logic and element 16g, counts and produce the element of storage output Q with the two pulse output of the reset pulse output O5 of microprocessor 10a when they reach certain setting value, and it is the memory element of exporting with respect to reset pulse repeatedly.
When counting machine (memory element) 16f produced storage output Q, display lamp 16c lit a lamp and exports halt circuit 16b action, and descended and be reset by the output of detecting element 17 as this counting machine 16f, and then display lamp 16c and output halt circuit 16b also are failure to actuate.
Again, diode 20d is connected between the collector terminal of the base terminal of transistor 19a and transistor 16d as required.
This example is different with above-mentioned example 1, has the 2nd vehicle-mounted load 8 by secondary microprocessor 10b control, according to respect to the reset pulse of master microprocessor 10a output RST or one of any with respect among the reset pulse output O5 of secondary microprocessor 10b, as counting machine 16f action and the output halt circuit 16b and the display lamp 16c action of memory element.
Again, what are set at,, at first export halt circuit 16b and display lamp 16c action according to reset pulse output repeatedly according to setting value with counting machine 16f.
As load, make not through the output contact of load-relay 7 and output contact 5a by power supply relay 5 is connected with Vehicular accumulator cell 2 by secondary microprocessor 10b control again.That is, can be so that vehicle-mounted load 8 directly is connected with the output contact 5a of power supply relay 5 with the obstructed overload relay 7 of the common junction of vehicle-mounted load 6d.
Again, in Fig. 1, each example shown in Figure 3, the 1st vehicle-mounted load 6a for example can be that fuel sprays with the multiple load with electromagnetic valve etc. of electromagnetic valve or automatic speed changing.
Similarly, as the 2nd load 8, can be the air suction valve control electrical motor that automatic vehicle speed control is used, can be idle controller with a plurality of loads of electrical motor and high-tension coil, exhaust gas sensor as the 3rd load 6b with electrothermal heater etc.
In these loads, automatic vehicle speed control is driving engine stop after making the load of exiter recovery initial position with electrical motor and idle controller with electrical motor etc. with air suction valve control.
Again, the effect of load-relay 7 is for example to be short-circuited when damaging etc. when be short-circuited accident or driver element of load, as disconnecting the backup means of feed circuit by load-relay 7 and adopt, this load-relay 7 is arranged on above-mentioned air suction valve control sprays in the load with electromagnetic valve etc. with electromagnetic valve, fuel with electrical motor and automatic speed changing.
So, in this example, be provided with i.e. the 2nd vehicle-borne secondary microprocessor of i.e. the 1st, the 3rd vehicle-mounted load of a plurality of loads of control other loads in addition, reset resetting of usefulness when carrying out the supervision of secondary microprocessor and abnormal condition according to master microprocessor, so under any one microprocessor makes a mistake action, situation out of control, can both export according to reset pulse immediately and reset, simultaneously, storing this state and can export unceasingly for the vehicle-mounted load of a part stops.
Example 3
In this vehicle electronic device, for the caused persistent anomaly of component wear of the electronic control circuit part that comprises microprocessor and caused temporary transient unusual by noise error action etc., for example, usually, input part before load driver connects pull-up resistor and pull down resistor, when unusual the generation, make to such an extent that load on secure side and continue action, or be provided with according to the action enabling signal and export the gate circuit that stops etc.
Above-mentioned action enabling signal is by making the monitor signal of microprocessor at the signal that just often moves for on/off, not all vehicle-mounted load all must this signal, sprays driving circuit portion with electromagnetic valve and for example can be arranged on fuel.
When this action enabling signal is reset according to reset pulse output at microprocessor, become again effectively and the beginning control load.
Relative therewith, output keeps the output halted state to output halt circuit of the present invention according to the reset pulse of one or many, even for example reset microprocessor and return to normally, also continues as to export and stops, till source switch is connected or inserted again, just remove this halted state.
As the vehicle-mounted load that requires above-mentioned output to stop to control, for example there is automatic vehicle speed control to control and uses electrical motor with air suction valve, and can construct the system that considers following situation, on other suitable material appropriate locations, owing to above-mentioned action enabling signal stops at output halted state in unusual, and can not at will carry out vehicle control.
Again, in above-mentioned example, situation for relevant engine control is illustrated, and also can be applicable to other various vehicles control, for example, for electronic machines relevant such as the place ahead of vehicle, rear, side monitor-control apparatus,, wish to stop its action and give a warning to the driver with display lamp or alarm etc. even temporarily produce abnormal condition with reliability.
