Abstract: The transmission of a recessive bit in a CAN message from a transmitting electronic control unit (ECU) is detected, over a controller area network. A dominant pulse is injected onto the network after a delay time into the detected recessive bit. Behavior of the transmitting ECU is detected, and a sample point for the transmitting ECU is characterized based upon the detected ECU behavior. An action signal is generated based upon the characterized sample point.

Abstract: An adaptive network repeater is disclosed for electronically connecting first and second subnetworks. The adaptive network repeater includes a first network interface coupled to the first subnetwork, a second network interface coupled to the second subnetwork, and a controller that monitors communication link status between the first and second subnetworks across the adaptive network repeater. Data received from the first subnetwork at the first network interface is retransmitted to the second subnetwork through the second network interface, and data received from the second subnetwork at the second network interface is retransmitted to the first subnetwork through the first network interface.
