Virtual Qualification

A method is presented that converts field life temperature data collected underhood during actual driving conditions into a segmented temperature cycling life cycle profile using rainflow counting techniques. This profile can then be used as the true field condition in performing Physics of Failure based virtual qualification or accelerated testing of an automotive engine control unit operating in an elevated temperature environment. The specific elements of this method and its validation on an engine control unit will be presented.

Car Accidents

Based on data from the Indonesian Traffic Corps by September 2019, the number of car accidents was dominated by rear-hit crashes with 6,966 accidents. Most of these accidents occurred during car convoys. It needs a car-to-car communication to increase driver awareness. One of the technologies that can be applied is Visible Light Communication (VLC) and infrared communication. The transmitted data are the vehicle speed data, throttle position, and brake stepping indicator. The data are obtained by reading the Engine Control Unit (ECU) in the car. The data are packaged from the three data and sent to other cars at day and night using VLC and infrared communication. The experimental results show that in a communication system that uses VLC, data can be exchanged between cars during the day up to 2 meters and at night up to 11 meters. Otherwise, in infrared communication, vehicles can communicate during the day up to 2 meters and at night up to 0.7 meter. The test was also carried out with some conditions such as rain, smoke, passers, and other vehicle lights.

SHRNUTÍ Byla vyvinuta programovatelna řidici jednotka na platformě CompactRIO s programem vytvořenym v prostředi LabVIEW. Jednotka byla vyvijena jako univerzalni a byla testovana při řizeni maleho zažehoveho motoru YAMAHA YZF R6. Jednotka je dale použitelna pro zažehove motory různe koncepce, přeplňovane i nepřeplňovane. Požadavku na univerzalnost jednotky byl přizpůsoben řidici program, ktery je uspořadan ve vzajemně komunikujicich samostatnych blocich. Zařizeni je rozšiřitelne o dalši I/O moduly, což umožňuje použiti dalšich snimačů, aktuatorů nebo modulů pro komunikaci. Rozhrani pro zesileni vystupů napajejicich zapalovani a vstřikovače bylo vyvinuto pro řizeni motoru YAMAHA YZF R6. Toto zařizeni zaroveň stabilizuje napajeni snimačů motoru a filtruje jejich vystupni signaly. Članek je shrnutim procesu vyvoje řidici jednotky motoru, obsahuje přehled použitych zařizeni, seznamuje s řidicim programem a zkušenostmi z testovani na motoru.

Insertion Tool

In order to ensure that every portion of the emission control software in a vehicle works, all fault conditions must be tested. Simply simulating faults in the software of the engine controller and reporting it to the OBD II scanner is inadequate; the fault condition must be injected externally to the Engine Control Unit (ECU). In the case of hard-to-reproduce mechanical failures, this is a challenging task. This paper discusses the development of a system capable of emulating various faults that a fuel injector can have while operating as part of a complete working vehicle. For the ECU to operate properly, all fuel injectors must be present in the vehicle, be fully functional, and must represent an accurate electrical load to the ECU. Then, the induced faults must be seamlessly inserted into the running system in less than 10μs and removed before the subsequent injection event. This was accomplished with a variety of COTS hardware, a simple custom circuit, and the use of a large, flexible FPGA platform.
