CONTROLLER AREA NETWORK SAMPLE POINT DETECTION

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 sa...

Summary: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. 通过控制器局域网，检测来自传输电子控制单元(ECU)的CAN消息中的隐性位的传输。在所检测的隐性位中的延迟时间后，显性脉冲被注入到网络上。检测传输ECU的行为，并且基于所检测的ECU行为来表征用于传输ECU的采样点。基于所表征的采样点生成动作信号。
