On calculating guaranteed message response times on the SAE J1939 bus
Roger Johansson, Jan Torin · 2002
Heavy truck manufacturers in automotive applications extensively use the SAE J1939 protocol definition. In this paper we demonstrates two simple methods for analysing worstcase scenarios on a J1939 CAN-bus. The first method can be used for quick estimation of bandwith requirements while the second method illustrates how maximum message delivery time (response time) can be calculated.
