Terminal one is connected with power module, the CAN communication card of the functional test computer of the connection of terminal two production line, the terminal two
It is connected with terminal seven, the LED module is connected with relay module, the power module is connected with terminal three, the terminal three
It is connected with VCU power port, the terminal four connects VCU driving channel interface, the VCU is driven described by terminal four
Relay module, the output end of the relay module is connected with terminal five, and the terminal five connects VCU digital signal channel
Pin.
Further, the target operation power supply is 12V or 24V.
Further, the relay module is connected with LED module, and the driving function for recognizing VCU by light flash is
No obstacle.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model cost is extremely cheap, can rapid deployment on multiple VCU production lines, can avoid hardware therefore
The VCU of barrier is delivered to next link of production, reduces enterprise's production capacity.
(2) the utility model provides a kind of quick VCU hardware capabilitys detection means, can automatic imitation VCU need access
External signal, realize quick detection and the positioning of VCU hardware faults.
Brief description of the drawings
Fig. 1 is entire car controller VCU hardware capability detection means functional block diagrams.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As illustrated, terminal one is the power input port of device, connect VCU target operation power supply, mostly 12V or
24V.The CAN communication card of the functional test computer of the connection production line of terminal two.Terminal two is connected with terminal seven.Terminal seven is connected
VCU CAN communication interface.VCU and functional test computer CAN communication are realized by terminal two and terminal seven, VCU can be detected
CAN communication function it is whether normal.Terminal one is by power input to power module.Power module is LED module and relay mould
Block is powered.LED module is connected with relay module.When relay module is acted, the working condition of LED module occurs mutually to strain
Change, the state of indicating relay.Power module is connected with terminal three.Terminal three is connected with VCU power port, is that VCU powers.
Terminal four connects VCU driving channel interface.VCU changes the state of relay by terminal 4 wheel driven motor type relay module.Relay
The output end of device module is connected with terminal five.Terminal five connects VCU digital signal channel pin.The output end of relay module
When state changes, different level states are provided with for VCU digital signal channel pin by terminal five.Power module
Power supply is provided for analog signal module.Analog signal module connects VCU analog signal pin by terminal six, is provided for VCU
Analog voltage.VCU is when carrying out functional test, and its data gathered and current operating state pass through terminal seven and terminal two
CAN passages are sent to test computer.Test computer and read the CAN data that VCU is sent, judge whether VCU hardware state is normal,
And shown and alarmed.
The device simulates VCU driving load by relay.Relay is connected with LED light, passes through the sudden strain of a muscle of light
The bright driving function for distinguishing VCU whether failure.The output channel of relay is connected with power supply, and is connected to VCU digital channel
On.During the actuating of relay, the level state of VCU digital input channels is changed, data signal is provided for VCU.The device is also
VCU provides multiple power supplies input, meets the VCU power demands of different voltage class.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
