Network dormancy method, network dormancy device and electronic control unit (ECU) based on open system and the corresponding interfaces for automotive electronics (OSEK) standard

Abstract

The invention relates to the network management field, and discloses a network dormancy method, a network dormancy device and an electronic control unit (ECU) based on an open system and the corresponding interfaces for automotive electronics (OSEK) standard. The network dormancy method based on the OSEK standard comprises the following steps: classifying ECUs to different local fields, loading personal identification, the identification of the local fields, the identification of states, and subsequent ECU identification in a first network management message produced by the ECUs, judging based on the first network management message, producing a dormancy order when all the ECUs in a local field meet dormancy conditions, and enabling all the ECUs in the local field to enter a dormancy state. Only if all the ECUs in the local field meet dormancy conditions, the ECUs in the local field enter the dormancy state through the network dormancy method based on the OSEK standard. The ECUs can enter the dormancy state unless all of the ECUs in a network segment meet the dormancy conditions in the prior art. Compared with the prior art, the network dormancy method based on the OSEK standard is favorable to realizing dormancy of the ECUs, and saves energy consumption.

Description

technical field [0001] The invention relates to the field of network management, in particular to a network dormancy method, device and ECU based on the OSEK standard. Background technique [0002] OSEK (open systems and the corresponding interfaces for automotive electronics) refers to the German automotive electronics open system and application interface standard, which is a standard widely used in automotive management systems in the market. [0003] In each device of the car, such as car windows, car doors, seats, air conditioners, etc., each is equipped with an ECU (Electronic Control Unit, electronic control unit) for managing itself. With the continuous development of the car industry, the degree of car intelligence With continuous improvement, the number of ECUs in the car is also increasing. Under the OSEK standard, CAN bus technology is used to realize data exchange when information is transmitted between each ECU. [0004] The inventor found in the research pro...
