The present disclosure relates to a scanning method for an electronic control unit in a vehicle and a vehicle diagnostic device. The vehicle diagnostic device is communicatively connected to at least two vehicle buses in the vehicle, each of the vehicle buses is connected to at least one electronic control unit in the vehicle. The scanning method determines a scan list corresponding to each of the vehicle buses. The scan list includes a to-be-scanned electronic control unit. The vehicle diagnostic device transmitting a scan signal on the vehicle buses in parallel according to the scan list corresponding to each of the vehicle buses, to determine whether the to-be-scanned electronic control unit in the scan list exists in the vehicle.

Scanning method for electronic control unit in vehicle and vehicle diagnostic device

The present invention provides a vehicle bus-based communication method and apparatus, a computer device and a storage medium. The vehicle bus-based communication method includes: monitoring data flows transmitted through a vehicle bus by vehicle electronic control units; determining undetected data flows in to-be-obtained data flows when the monitoring reaches a first time length; broadcasting data flow obtaining requests through the vehicle bus, the data flow obtaining requests specifying queries for the undetected data flows; and obtaining data flows that are fed back through the vehicle bus in response to the data flow obtaining requests. When data flows of a vehicle are obtained through a vehicle bus, data flows on the vehicle bus are first obtained in a monitoring manner, thereby ensuring data flow obtaining efficiency. After the monitoring is performed for a period of time, data flows that are not obtained in a monitoring-and-obtaining manner are obtained by sending corresponding data flow obtaining requests to the vehicle bus, so that it is ensured that relatively more complete data flows of the vehicle can be obtained.
