Filament temperature is gradually cooling to ambient temperature.After the bulb of halogen vehicle lamp enters normal operating conditions, the lamp of the halogen vehicle lamp
Silk temperature is very high, and this state is called hot.If halogen vehicle lamp is again turned within the short time after closing, because its filament dissipates
Heat is slower, it is impossible to quickly return to ambient temperature, and when being again turned on, its dash current value for producing and time are much smaller than cold
State starts.
And carry out in performance testing process in automobile controller, in order to reduce detection time, bulb open and close when
Between be spaced generally shorter, this can cause the dash current of bulb and time during detection to be much smaller than actually used bar
Part, because the dash current of bulb can indirectly reflect the correlated performance of automobile controller, such as automobile controller circuit board
Life-span etc., therefore, the structure of automobile controller performance detection of the prior art is inaccurate.

The executive agent for applying the automobile controller method for testing performance of example is automobile controller device for detecting performance, the automobile controller
Energy detection means can be integrated in automobile controller, it is also possible to be individually configured.
As shown in figure 1, being the schematic flow sheet of the automobile controller method for testing performance according to the present embodiment.
Step 101, obtains the cool time of target car light.
The car light of the present embodiment can be halogen vehicle lamp.Specifically, can with by the way of experiment obtaining target carriage
The cool time of lamp, for example, after opening target car light for a period of time, target car light is closed, and carry out timing, when discovery target
When the temperature of the filament of car light is gradually cooling to ambient temperature, its cool time is recorded, or when dispatching from the factory the cool time of car light
Just set, staff can be by input store cool time of the car light, so as to automobile controller performance detection
When device needs, the cool time of the car light is obtained from memorizer.
Step 102, opens and detects that target car light, detection close target car light after finishing, and starts timing.
Automobile controller device for detecting performance opens target car light, and is detected, when detection time is reached, closing should
Target car light, now, target car light proceeds by cooling.Start timing while closing target car light, can specifically trigger meter
When device carry out timing.
Step 103, successively pair car light different from target car light opened, detected and detected finish after close behaviour
Make, until the time of timing reaches cool time, and return execution step 101.
Hypothesis pre-sets n car light, and the target car light can be the 1st car light, or m-th car light, specifically
Can be set according to actual needs, wherein m is integer more than 1 and m.The car light different from target car light can be m+1
Individual car light, the m+2 car light, the m+3 car light ....The target car light for assuming the present embodiment is the 1st car light, and detection is completed
And close after the 1st car light, the 1st car light enters cooling, then opens the 2nd car light and is detected, has detected
Bi Hou, detection closes the 2nd car light after finishing, and then opens and the 3rd car light and is detected, detection close after finishing this
3 car lights...And so on, the cool time of the 1st car light is reached, return the step of detecting the 1st car light.
It is pointed out that assuming the cool time that the 1st car light is had arrived at when n-th car light is detected, Ke Yixuan
Select after the detection of n-th car light is completed and closed, return again to the step of detecting the 1st car light, and reset timer, when the 1st
After the detection of individual car light is finished and closed, restart timing.
According to the automobile controller method for testing performance of the present embodiment, by arranging multiple car lights, and successively to these cars
Lamp is detected, as such, it is possible to be cooled down to the car light regular hour detected and closed, and then causes the bulb of car light
Dash current and time and actual service conditionss match as far as possible, so, the related test results of automobile controller performance compare
Accurately.

State, then can be switched with disconnection detection, and now, the monitoring of automobile controller device for detecting performance flows through the Static Electro of sampling components and parts
Stream, it is possible to know the relevant information of automobile controller according to quiescent current, for example, when quiescent current change is excessive, has very much
Possibly automobile controller there occurs short circuit or internal hardware has gone out other problems, now can be to the problem of automobile controller
Investigated.So, by flow through sampling components and parts monitoring automobile controller low-power consumption when quiescent current, it is possible to realize
Performance detection to automobile controller.
