Abstract
A controller area network (CAN) node is described for determining a bus load on a CAN bus. An indication of a time window duration of a time window is received by the CAN node and a start time for determining a bus load and an end time based on the start time and the time window duration is defined. The bus load is based on determining whether the CAN bus is active for each bit of one or more bits detected on the CAN bus between the start time and the end time. The bus load is compared to a threshold range. A signal is sent to a host processor if the bus load exceeds or falls below the threshold range.
