The present invention is intended to provide a kind of engine electrical system monitoring method, for when sensor in engine electrical system
When failure or line fault cause automobile to prevent engine auto-ignition mechanism failure, monitors engine electrical system failure and issue report
Alert signal, prevents engine auto-ignition and vehicle spontaneous combustion.
Fig. 1 is the flow chart of the monitoring method for the engine electrical system that the embodiment of the present invention one provides.The present embodiment
Executing subject can be electronic control unit ECU, as shown in Figure 1, the method for the present embodiment the following steps are included:
S101: the current value and voltage value of the engine electrical system are obtained.
In the present embodiment, engine general supply is engine electrical system power supply.It can be by obtaining engine electrically
The current value of the corresponding general supply of system, obtains the current value of engine electrical system.
Existing voltage sensor by the way that engine electrical system is arranged in obtains the voltage value of engine electrical system.
S102: according to the current value and voltage value, the actual power loss of the engine electrical system is determined.
Wherein, the actual power loss of engine electrical system can be the performance number of engine electrical system.
Specifically, when actual power loss be engine electrical system performance number when, can by general supply current value with
Voltage value is multiplied, and obtains the actual power loss of engine electrical system.
S103: the rated power worked normally according to the actuator of acquisition determines the theory of the engine electrical system
Power consumption.
In the present embodiment, when each actuator is all in normal operating conditions in engine electrical system, it is believed that respectively hold
The theoretical power consumption of row device is rated disspation, and engine is in normal operating conditions at this time, can be according to the rated power of each actuator
Determine the theoretical power consumption of engine.
Specifically, the working condition of each actuator in available, if the actuator is in failure or shutdown status, really
The fixed actuator is in abnormal operating state, otherwise, is in normal operating conditions.
Specifically, the rated power of each actuator in normal working conditions, root in available engine electrical system
The theoretical power consumption of the engine electrical system is determined according to the rated power summation of all actuators.
S104: when the practical total power consumption of the engine electrical system and the difference of theoretical total power consumption are greater than given threshold
When, alarm signal is issued to warning device.
Wherein, warning device can be phonetic alarm or buzzer siren etc..
Wherein, given threshold, for indicating occur deviation between the actual power loss of engine electrical system and theoretical power consumption
Maximum magnitude.When the difference between the actual power loss of engine electrical system and theoretical power consumption is greater than nominal threshold value, explanation
There is short circuit or short trouble in present engine, and leading to engine electrical system and vehicle, there are spontaneous combustion risks.
The reason of engine breaks down is different, and the influence to engine electrical system working condition is also different.Such as it sends out
The certain elements of motivation electronic control part under high temperature, high pressure and the curent change poor working conditions such as frequently, can make certain for a long time
A little component ageings or performance degradation, cause engine to break down.After failure, the practical total of engine electrical system can be made
Power consumption and theoretical total power consumption are unequal, can more early judge that engine electrical system breaks down.If engine electrical system
The difference of practical total power consumption and theoretical total power consumption is less than nominal threshold value, then the element fault there is no it is serious to influence engine without
Method normally starts, and engine auto-ignition risk is not present.In another example the capacitor or triode inside electronic igniting controllor are hit
Wear, ignition controller operation irregularity can be made, cause ignition coil secondary winding that can not generate high-voltage electricity, high pressure firewire not arcing or
Spark is weak, then Current electronic ignition controller failure can cause engine electrical system short trouble or open circuit fault occur,
Cause engine electrical system that can not start or operation irregularity.Short circuit in engine electrical system at this time, electric current wink part become
Greatly, actual power loss also becomes larger, if the actual power loss of engine electrical system is greater than the reality of theoretical power consumption and engine electrical system
When difference between border power consumption and theoretical power consumption is greater than nominal threshold value, illustrate that the abnormal numerical value of current flow will lead to engine and deposit
In the risk of spontaneous combustion, then ECU sends alarm signal to warning device, and present engine failure is prompted there are natural risk and to close
Engine power.When occurring open circuit fault in engine electrical system, the actual power loss of engine electrical system becomes smaller, and starts
The actual power loss of electrical-mechanical system is less than the difference between theoretical power consumption and the actual power loss and theoretical power consumption of engine electrical system
When value is greater than threshold value, illustrate certain actuator operation irregularities in present engine, then ECU transmission alarm signal to warning device,
Prompt present engine operation irregularity needs to debug.
From the description of the present embodiment it is found that determining engine electrical system by obtaining electrical system current value and voltage value
Actual power loss, further according to the theory for obtaining actuator rated power in normal working conditions and determining engine electrical system
Power consumption.By the way that the actual power loss of engine electrical system is compared with theoretical power consumption, when electrical system actual power loss with
When the difference of theoretical power consumption is greater than threshold value, it is believed that there are failures for engine electrical system, issue alarm signal to warning device.This
Inventive embodiments are by being compared judgement engine electrical system for the actual power loss of engine electrical system and theoretical power consumption
Whether break down, do not need that big quantity sensor is arranged within the engine, reliability is higher, is conducive to driver and finds vapour in time
Car engine failure reduces the risk of engine auto-ignition and vehicle spontaneous combustion.

The actual power loss and theoretical power consumption of gas system, judge whether engine electrical system breaks down.The present embodiment is only needed total
Power supply goes out to increase by a current sensor, and without arranging big quantity sensor in engine, structure is simple, and cost of implementation is low, is easy to
It popularizes, can effectively reduce the risk that spontaneous combustion or traveling exception occurs in the process of moving in automobile.
In one embodiment of the invention, it on the basis of above-mentioned Fig. 1 or Fig. 2 embodiment, issues and reports in step S104
After alert signal to warning device, further includes: close engine electrical system according to alarm signal.
Wherein, after judging that short circuit failure or operation irregularity failure occurs in engine electrical system, according to alarm
Signal controls engine power-off in time, into interrupted oily operating condition, automobile is avoided to continue to travel engine continuation misoperation and draw
The engine auto-ignition risen or vehicle spontaneous combustion.
It is described from the present embodiment it is found that cutting off electrical system operation irregularity feelings in time by closing engine electrical system
