METHOD OF TESTING ON-BOARD SYSTEMS / DEVICES FOR MEASURING AND DISPLAYING THE TRAVERSED PATH OF A VEHICLE FOR SUSCEPTIBILITY TO AN ELECTROMAGNETIC FIELD

摘要

FIELD: test technology.;SUBSTANCE: invention relates to systems for electromagnetic testing of vehicle systems. In the test method, the vehicle is installed on a dynamometric roller bench located in an anechoic chamber, where radiators of a high-frequency electromagnetic field are also located. Before the test driving cycle is carried out, a calibration driving cycle is performed, the modes of which repeat the test modes with excluded exposure to the high-frequency field. During calibration cycle data recorded by onboard systems and measuring systems of test bench are recorded, and then error of data of onboard systems is calculated relative to data of test bench. When performing the test cycle, data recorded by onboard systems and measuring systems of the test bench are recorded. After the test cycle completion, data on the passed track recorded by the onboard systems are compared with data of the measuring systems of the stand. Test result is considered to be positive if traversed path measured by onboard systems corresponds, based on measurement error, to travel distance recorded by measuring system of test bench.;EFFECT: higher reliability of results obtained as a result of tests.;1 cl, 1 dwg
