Enable N number of driving chip so that N number of driving chip is driven and diagnosed to corresponding load.
Wherein, N number of driving chip to respective load after diagnosing, during can diagnostic message be fed back to by wire
Entreat process chip.
And then central processing element according to the value of feedback of N number of driving chip of acquisition and/or each value of feedback it is lasting when
Between, determine the first state of N number of load.
Wherein, in the present embodiment, value of feedback can be the diagnosis magnitude of voltage of load.
It is understood that in this embodiment, central processing element can obtain the value of feedback of N number of driving chip, also may be used
To obtain the duration of the value of feedback of N number of driving chip, the value of feedback of N number of driving chip and holding for value of feedback can also be obtained
Continuous time, the application are not specifically limited to this.
Step 403, it is if invalid, according to the value of feedback of N number of driving chip of acquisition and/or each value of feedback it is lasting when
Between, the second state of N number of load is determined respectively.
Specifically, when it is determined that current control command is invalid, then central control chip is directly anti-according to N number of driving chip
The diagnostic message of feedback, determine the second state of N number of load.
Wherein, N number of driving chip to respective load after diagnosing, during can diagnostic message be fed back to by wire
Process chip is entreated, to obtain the second state of N number of load.
Forward engine room Intelligent electrical box control method provided in an embodiment of the present invention, according to the current state of vehicle, is determined
Whether current control command is effective, if it is determined that and control command is effective, then enables N number of driving chip respectively, and according to acquisition
N number of driving chip value of feedback and/or each value of feedback duration, determine the first state of N number of load respectively；If it is determined that
Control command is invalid, then according to the duration of the value of feedback of N number of driving chip of acquisition and/or each value of feedback, determines N respectively
Second state of individual load.Loaded hereby it is achieved that being directly driven using driving chip, and to loading the mesh diagnosed
, so as to when load occurs abnormal, driver be reminded in the very first time, traffic safety is ensure that, improve user and drive
Car body is tested.
By above-described embodiment, the current state of the invention according to vehicle, determine whether current control commands are effective,
And the status information of N number of load is determined according to determination result.With reference to Fig. 5, when effective to current control commands or invalid,
Determine that the status information of N loads is specifically described.
Fig. 5 is the flow chart of the forward engine room Intelligent electrical box control method of an alternative embodiment of the invention.
As shown in figure 5, the forward engine room Intelligent electrical box control method may comprise steps of：
Step 501, according to the current state of vehicle, it is determined that whether current control command is effective, if effectively, performing step
Rapid 502, otherwise perform step 509.
Step 502, N number of driving chip is enabled respectively, and according to the value of feedback of N number of driving chip of acquisition and/or each anti-
The duration of feedback value.
Step 503, if the value of feedback of the first driving chip is equal to first voltage threshold value, the duration is more than very first time threshold
Value and be less than the second time threshold, it is determined that first be connected with the first driving chip loads currently and ground short circuit.
In the present embodiment, first voltage threshold value, very first time threshold value and the second time threshold, can according to be actually needed into
Row relative set, the application are not limited this.
Wherein, very first time threshold value, refer to that failure continues the threshold value of time of origin.
Second time threshold, when referring to the first load with ground short circuit, self- recoverage time threshold.
That is, the present embodiment is by the way that the duration of the first driving chip value of feedback and very first time threshold value are carried out
Compare, to filter out the presence fluctuation because of value of feedback, and cause last diagnostic the situation of error occur.
During specific implementation, the value of feedback of the first driving chip and the duration of value of feedback are received when central processing element
Afterwards, above-mentioned value of feedback can be compared with first voltage threshold value, to determine whether value of feedback is equal to default first voltage
Threshold value.
When it is determined that value of feedback is equal to first voltage threshold value, further by the duration of value of feedback and very first time threshold value
It is compared, to determine whether the duration of value of feedback is more than very first time threshold value.
If the duration of value of feedback is more than very first time threshold value, then by the duration of value of feedback and the second time threshold
Value is compared, to determine whether the duration of value of feedback is more than the second time threshold.
If the duration of value of feedback is less than the second time threshold, it can determine that what is be currently connected with the first driving chip
The running status of first load is and ground short circuit.
Step 504, control disconnects the driving to the first load.
Wherein, after the driving to the first load is controlled, self-recovery method can be used to repair the first load and ground short circuit
Situation.So as to effectively avoid the shorted to earth for causing the first load that transience occurs because of some special circumstances, recover normal
Situation about can not be again started up afterwards occurs.
Step 505, if the value of feedback of the second driving chip is equal to first voltage threshold value, the duration is more than the second time threshold
Value, and after controlling the second load to carry out self- recoverage M times, the value of feedback of the second driving chip is still equal to first voltage threshold value.
