Problems solved by technology
[0003] In the process of the existing dormancy control method of the automobile network segment, the judgment of the dormancy condition of the corresponding system network segment is carried out by means of whether to cut off the power, which leads to low judgment accuracy and reduces the accuracy of dormancy control. In the process of the network segment dormancy control method, the dormancy control can only be realized for a single system network segment, which makes the coordination effect between the vehicle network segments poor, which easily leads to the failure of the car wake-up operation and reduces the user experience.

The invention provides an automobile multi-segment cooperative dormancy control method and system. The automobile multi-segment cooperative dormancy control method comprises the steps of correspondingly obtaining segment states of a power segment, an automobile body segment and an information segment on an automobile; judging whether the obtained segment states all satisfy corresponding dormancy conditions or not; and when it is judged that the segment states all satisfy the corresponding dormancy conditions, correspondingly transmitting dormancy instructions to the power segment, the automobile body segment and the information segment so as to control ECU nodes, corresponding to network nodes, on the power segment, the automobile body segment and the information segment to simultaneouslysleep. According to the automobile multi-segment cooperative dormancy control method and system, through adoption of a design of correspondingly transmitting the dormancy instructions to the power segment, the automobile body segment and the information segment, all ECU nodes are controlled to sleep so as to solve a problem that only partial system segments enter a dormant state; and therefore, acooperation effect between the segments is improved, and the normal operation of a follow-up automobile awakening step is guaranteed.
Description
Technical field [0001] The invention relates to the technical field of car sleep control, in particular to a method and system for car multi-segment cooperative sleep control. Background technique [0002] With the continuous development of the automotive industry, the degree of automotive intelligence continues to increase, and more and more electronic control subsystems are integrated in the vehicle network system. The vehicle network system usually includes at least two electronic control subsystems such as power transmission system, chassis safety system, body control system, instrument display system, and infotainment system, as well as gateway controllers connected to each electronic control subsystem, and each electronic control subsystem Communication is carried out through the gateway controller. The electronic control subsystem includes at least one electronic control unit (Electronic Control Unit, ECU for short), and each ECU is connected to a gateway controller and c...
