Nowadays almost all motorized vehicles use electronic control units (ECUs) to control parts of a vehicle’s function. A good way to understand a vehicle’s behaviour is to analyse logging data containing ECU internal variables. Data must then be transferred from the ECU to a computer in order to study such data. Today, Keyword Protocol (KWP) requests are used to read data from the ECUs at Scania. The method is not suitable if many signals should be logged with a higher transfer rate than the one used today. In this thesis, communication protocols, that allow an ECU to communicate with a computer, are studied. The purpose of this master’s thesis is to examine how the transfer rate of variables from Scania’s ECUs to a computer can become faster compared to the method used today in order to get a more frequent logging of the variables. The method that was chosen was implemented, evaluated and also compared to the method used today. The busload, total CPU load and CPU load for the frequency used during the experiments, 100 Hz, was also examined and evaluated. The experiments performed show that the method chosen, data acquisition (DAQ) with CAN Calibration Protocol (CCP), increased the transfer rate of the internal ECU variables significantly compared to the method using KWP requests. The results also show that the number of signals have a major impact on the busload for DAQ. The busload is the parameter that limits the number of signals that can be logged. The total CPU load and the CPU load for 100 Hz are not affected significantly compared to when no transmissions are performed. Even though the busload can become high if many variables are used in DAQ, DAQ with CCP is preferable over KWP requests. This is due to the great increase in transfer rate of the ECU internal variables and thus a great increase in the logging frequency. / Nuförtiden används styrenheter (ECUer) för att styra delar av ett fordons funktion i så gott som alla motoriserade fordon. Ett bra sätt att förstå ett fordons beteende är att analysera loggningsdata som innehåller interna styrenhetsvariabler. Data måste då överföras från styrenheten till en dator för att data ska kunna studeras. Idag används Keyword Protocol-förfrågningar (KWP-förfrågningar) för att läsa data från Scanias styrenheter. Metoden är inte lämplig om man vill logga många variabler med en högre överföringshastighet än den som används idag. I detta examensarbete studeras kommunikationsprotokoll som tillåter en styrenhet att kommunicera med en dator. Examensarbetets syfte är undersöka hur överföringshastigheten av variablerna, från Scanias styrenheter till en dator, kan ökas jämfört med den metod som används idag för att få en mer frekvent loggning av variablerna. Metoden som valdes implementerades, utvärderades och jämfördes med metoden som används idag. Busslasten, totala CPU-lasten och CPU-lasten för den frekvens som användes under experimenten 100 Hz har också undersökts och evaluerats. De utförda experimenten visar att den valda metoden, data acquisition (DAQ) med CAN Calibration Protocol (CCP), ökade överföringshastigheten av de interna styrenhetsvariablerna betydligt jämfört med metoden KWP-förfrågningar. Experimenten visar också att antalet signaler har stor inverkan på busslasten för DAQ. Busslasten är den parameter som begränsar antalet signaler som kan loggas. Den totala CPU-lasten och CPU-lasten för 100 Hz påverkas inte betydligt jämfört med när inga överföringar görs. DAQ med CCP är att föredra framför KWP-förfrågningar även om busslasten blir hög för DAQ då den stora ökningen i överföringshastighet av de interna styrenhetsvariablerna medför en mer frekvent loggning av variablerna.

Customized truck is a relevant and high-profit part of Scania’s market. Nowadaysdesigners do not have a self-developed electric control unit for introducing non-standardfunctionality.
