ENGINEERING FOR RURAL DEVELOPMENT Jelgava, 29.-30.05.2008. 183 PARAMETER AND EVENT REGISTRATION SYSTEM OF VEHICLE

Abstract. It is well known, that great economy of fuel can be achieved by proper exploitation of vehicle. At the same time it is difficult to monitor work style and habits of driver. New generation of trucks already has some factory built-in monitoring means, mostly targeted to driver’s personal use but less for fleet owner. Some companies offer additional memory equipped or telemetry systems, which may be installed on vehicle to supervise different parameters and events, including fuel consumption. At the same time practically all systems in the market do not measure amount of fuel filled in tanks and its consumption in time with acceptable accuracy. System presented in this article allows with high accuracy measure amount of fuel in tanks of vehicle and its consumption independently from on-board computer system and record it together with other selected parameters and events in recorder memory. These parameters may include vehicle speed, engine rpm and temperature, cargo department and outside air temperature, geographical position from GPS, etc. Device has modular design to give flexibility at installation and future upgrades. It may be equipped with GSM-GPRS telemetry, driver identification and immobilizer, wireless data reading and programming as an option. Other part of this system is evaluation software, giving possibility to owner or fleet administrator to analyze records from equiped trucks in details
