Problems solved by technology

This system ensures the high efficiency and real-time transmission of information and reduces the network load rate. However, the solution provided by this system is suitable for the network management strategy during the driving of the car, and it does not take into account that the battery can only provide electric energy when the car is parked. In the case of , the entire network needs to be in a low power state

Abstract

The invention discloses a network management method for an electronic control system in parking braking of an automobile. Electronic control units are divided into a static electronic control unit and a sleep electronic control unit. The static electronic control unit stops working in parking braking the automobile, the aim of saving electric energy in parking braking of the automobile is achieved by conversion of four states of the sleep electronic control unit including sleep, awakening wait, normal operation and sleep wait. The network management method can remarkably reduce electric energy consumed by the electronic control units, reduces electric energy consumption of a storage battery, can simultaneously control the electronic control units of the whole automobile such as a power system and a chassis system, and is simple, convenient, rapid, efficient and easy to achieve.

Description

technical field [0001] The invention relates to the field of electronic control of automobiles, in particular to a network management method of an electronic control system when an automobile is parked and braked. Background technique [0002] At present, the electronic control system of the car needs to be in a working state under normal power when the car is parked. In the normal power state, only the battery can provide electric energy, but the power provided by the battery is limited. Therefore, how to realize the electronic control system Low power consumption when the car stops becomes a very important issue, but now the network management method of low power consumption when the car is parked is mainly used in the body system and entertainment system, but lacks effective management of the power system and chassis system , and the network management method generally adopts the direct network management of each system module, which is relatively cumbersome. [0003] Ch...
