Embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, a kind of entire car controller test fixture, including 32 torsion adjustable rheostats 6,14 of sub switch 5,6
Individual 7,1 81pin plug connectors (not shown)s of double pin indicator lamps and some connecting wires, turn round sub switch for 32 and form 32 tunnels
Digital input circuit 1,6 is adjustable, and rheostat forms the double pin indicator lamp groups of 6 road analog input circuit 2,4 into 4 road flash
The double pin indicator lamp groups of output circuit 3,10 into the low side output circuit 4 in 10 tunnels, wherein, 32 are turned round two contacts difference of sub switch
Ground connection and the positive pole of connection external power supply, another contact connect by the way that connecting wire 81pin plug connectors are corresponding respectively；6 can
Rheostatic termination positive source, sliding end ground connection are adjusted, the other end connects by the way that connecting wire is corresponding with 81pin plug connectors respectively
Connect；Form 4 of flash output circuit double one pin ground connection of pin indicator lamps, another pin respectively by connecting wire with
81pin plug connectors are corresponding to be connected；10 double pin one pins of indicator lamp for forming low side output circuit connect positive source, another
Pin passes through wire connection corresponding with 81pin plug connectors respectively.
Specifically used method, by the plug connector of entire car controller with the plug connector of test fixture is supporting is connected, by vehicle
Controller is connected with the CAN lines that test fixture is drawn jointly by USBCAN cards with host computer, then arrives detection download program
In entire car controller.Hot line job when testing entire car controller, operating procedure are as follows：Test the input of entire car controller digital quantity
When, the torsion sub switch of test fixture is stirred, observes instruction lamp on/off situation corresponding to this switch, and this switch corresponds to host computer
Digital input amount is high effective or low effective, pays attention to put switch in low order before entire car controller is tested,
In order to avoid it is excessive in powered on moment excessively stream, damage entire car controller；When testing the input of entire car controller analog signal, adjustment test work
The corresponding adjustable rheostat of dress, whether observation host computer correspond to each analog signal regularly changing, pays attention to observing each analog quantity
Scope；When testing the output of entire car controller flash, the state of the corresponding indicator lamp of height effectively observation by clicking on host computer；Together
When the low side of reason test entire car controller exports, the state of the low corresponding indicator lamp of effectively observation by clicking on host computer.Grasp herein
During work, the stateful all displays of institute are normal, then each function of entire car controller is intact, can normal use.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.Every equivalent structure done using the utility model specification and accompanying drawing content or equivalent flow conversion, it is included in this
Within the scope of patent protection of utility model.
