CONTROL OF TECHNICAL CONDITION OF THE AUTOMATIC TRANSMISSION

Abstract

The aim of the study was to develop an automatic gearbox troubleshooting algorithm based on performance tests, as existing algorithms do not allow to determine a problem in a car at the lowest cost. Based on the analysis, it was proposed to change the algorithm for diagnosing an automatic transmission of cars. As a result of performance tests using the Consult III+, the measurements of the degree of depressing the accelerator pedal, changes in vehicle speed and engine speed depending on time, changes in the degree of throttle opening and pressure in the high-pressure fuel line to detect a faulty condition of a gearbox were made. The measurement time for each of the indicators was not more than 30 seconds. An automatic gearbox troubleshooting algorithm was developed using an interrogatory part.
