COMPLEX OF DEVICES FOR REGISTRATION OF VEHICLE PARAMETERS DURING MOVEMENT

Abstract

To verify the adequacy of the mathematical model of vehicle movement on the driving cycle, there is a need for a set of devices to register its parameters while driving. As such parameters the wheeled tractor with the gas engine the frequency of rotation of a cranked shaft, rarefaction in an inlet collector, an angle of opening of throttle valves, speed of movement is chosen. The hardware part of the complex has been developed: sensors have been selected, an analog-to-digital converter (ADC), a laptop for information processing have been selected, sensors have been connected to the ADC, and the ADC to the laptop. A program for monitoring and recording sensor signals on a laptop has been selected. A program has been developed for the final processing of the obtained data - the conversion of sensor signals into the values ​​of the studied parameters. The set of devices is mounted on a wheeled tractor MTZ-80 with a gas engine converted from a diesel engine. Several recordings of selected parameters in road conditions were made
