In a word, teaching automobile electric control system interactive controller is independently of the control outside automobile and monitoring device,
The device fills up the blank that complete vehicle fault in vocational education universities and colleges automobile services class professional teaching excludes teaching aid missing, can be " mould
Block teaching " and practical teaching are really organically combined, and setting function by the failure of controller can teach automobile major
Learn more directly perceived, lively, enhancing teaching operability improves the academic program enthusiasm of student.Meanwhile, the device overcome with
The grafting test on former car, reduces the probability of damage of auto parts toward vehicle teaching process, reduces instruction cost.
Finally it should be noted that：Above example is only used to illustrate the technical solution of the utility model, rather than its limitations；
Although being described in detail to the utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in previous embodiment, or to which part or all technical characteristic
Carry out equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from the utility model right and want
Seek limited range.
