It send, the control signal of each button is converted to by electric signal instruction by mainboard, mainboard passes through CAN bus to be measured and vehicle-mounted control
Device communication connection, mainboard send command signal to Vehicle Controller by CAN bus to be tested, and Vehicle Controller refers to simulation
Show that terminal called connects, Vehicle Controller is shown according to the instruction execution action signal received by simulation instruction terminal
Execute the result of the action, simulation instruction terminal be left and right turn signal lamp, brake signal lamp, emergency lamp signal telegraph, long-and-short distant light,
The action signal that Vehicle Controller executes is indicated that power supply is by fog lamp and the display screen to show vehicle real time
Mainboard, Vehicle Controller and simulation instruction terminal power supply, are respectively that various pieces are powered using power supply, mainboard is for sending
Control instruction is to Vehicle Controller and receives Vehicle Controller according to the feedback result of instruction execution relevant action to total to CAN
Whether qualification is judged line, and the feedback result that execution acts is sent to mainboard and judges to survey by feedback result by Vehicle Controller
Whether the CAN bus of examination is qualified, and indicator is connected on mainboard, indicates judging result by indicator, indicator is referred to by red
Show that lamp, green indicator light and loudspeaker are constituted, if loudspeaker issue the sound to CAN bus test passes control green indicator light simultaneously, if
CAN bus test failure controls the sound that red indicating light is bright while loudspeaker sending is different from when qualification.
Generally, the present invention has structure simple, easy for operation quick, and common laborer can directly operate pair
CAN bus is tested, and test effect and efficiency are substantially increased, and effectively improves production efficiency, has high use value
The advantages of.
