Introduction of Periodical Maintenance/Inspection of Motor Vehicles in Use and Its Automated System 852261

To assure safe runnings of motor vehicles, laws in Japan have made it statutory for motor vehicles to periodically undergo motor vehicle tests. During these tests (diagnosis and inspections), brakes, speedometers, wheel alignment, headlamps, exhaust emissions and so forth are inspected by means of appropriate pieces of test equipment. After the test results have been compared against the reference values, "pass/fail" evaluation is indicated, memorized and recorded. Moreover, instructions for the driver are provided on indicators. The test equipment with such capabilities has been employed in the government-run motor vehicle inspection stations in Japan.

In addition to such government-run motor vehicle inspection stations, this paper deals with an automated motor vehicle inspection system which has been designed compactly and which is to be used in nongovernmental service shops directly connected with services and repairs.
