Today, as the number of electronic control units(ECUs) in automotives increases, the complexity of in-vehicle network also increases. Controller area network(CAN) is the most widely used protocol in in-vehicle network but it has limited bandwidth. CAN buses with limited bandwidth may increase in bus load due to the increased complexity of the CAN bus. Thus, low priority messages in CAN bus may be delayed or missed, making it difficult to predict the worst-case latency. There have been studies on data compression algorithms to reduce the amount of data transmitted on the CAN bus at a low cost. However, it is difficult to select the optimal compression algorithm because previous studies utilized different experimental environments, so it is difficult to compare performance across each study. This paper presents peak load and worst-case message latency when using representative data compression algorithms. Each algorithm was measured in the same experimental environment that implemented using CANoe in order to compare performance. |
