“On calculating
guaranteed message response times on the SAE J1939 bus”
Abstract
Heavy truck
manufacturers in automotive applications extensively use the SAE J1939 protocol
definition. In this paper we demonstrates two simple methods
for analysing worst-case 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.
