origin
Automobile inspection technology originates from automobile maintenance technology and develops with the development of automobile technology. In the early process of automobile maintenance, it is mainly through experienced maintenance personnel to find automobile faults and carry out targeted maintenance. That is, people used to say "look (see)" (for example, by observing the appearance of the car or the running state of the car to judge the fault) and "smell (listen)" (for example, by judging the fault by the running sound of the engine).
"Ask" (for example, by asking the driver about the vehicle usage or phenomena to judge the fault) and "touch" (for example, by feeling the temperature, vibration, pressure and other phenomena by hand to judge the fault). With the progress of modern electromechanical measurement and control technology, especially the progress of computer technology, automobile detection technology has also developed rapidly.
