Embodiment 1

[0059] An embodiment of the present invention provides a vehicle bus network abnormality monitoring method, including the following steps:

[0060] (1) After the vehicle is powered off, the vehicle remote monitoring terminal monitors the bus message status of each network segment in the vehicle bus network to identify whether the vehicle cannot go to sleep or whether the vehicle network is frequently awakened in an abnormal state after power off;

[0061] (2) When the vehicle cannot go to sleep or the vehicle network is frequently woken up abnormally, the vehicle remote monitoring terminal will send the abnormal state of not being able to go dormant or the vehicle network is frequently woken up to the vehicle cloud platform, and the vehicle cloud platform will remind the user through the client terminal At this time, the vehicle bus network wakes up frequently;

[0062] (3) When the vehicle network is normal, the vehicle remote monitoring terminal continues to monitor each net...

Embodiment 2

[0085] like figure 2 Shown is a vehicle bus network abnormality monitoring system provided by an embodiment of the present invention, including: a vehicle remote monitoring terminal, a vehicle cloud platform and a client terminal;

[0086] The vehicle remote monitoring terminal is connected to the bus network of the vehicle. It is used to monitor the bus message status of each network segment in the vehicle bus network after the vehicle is powered off, so as to identify whether the vehicle cannot enter sleep or the vehicle network is blocked after the vehicle is powered off. The abnormal state of frequent wake-up, and when the vehicle cannot enter sleep or the vehicle network is frequently awakened, it will send the abnormal state of being unable to enter sleep or the vehicle network is frequently awakened to the vehicle cloud platform. When the vehicle network is in normal state, continue to monitor the vehicle bus Monitor each network segment in the network;

Abstract

The invention discloses a whole vehicle bus network abnormity monitoring method and a system, and belongs to the technical field of vehicle control, and the method comprises the steps that after a whole vehicle is powered off, a vehicle remote monitoring terminal monitors the bus message state of each network segment in a vehicle bus network so as to identify whether the vehicle is in an abnormal state wherein the vehicle cannot enter dormancy or frequent wakeup of the vehicle is caused; when the vehicle network is in an abnormal state wherein the vehicle cannot enter dormancy or frequent wakeup of the vehicle is caused, the vehicle remote monitoring terminal sends the abnormal state wherein the vehicle cannot enter dormancy or frequent wakeup of the vehicle is caused to a vehicle cloud platform; the vehicle cloud platform reminds a user that the vehicle is in an OFF gear and is in the abnormal state wherein the vehicle cannot enter dormancy or frequent wakeup of the vehicle is caused through a client terminal; and when the vehicle network state is normal, the vehicle remote monitoring terminal continues to monitor each network segment in the vehicle bus network. According to the invention, after the vehicle is powered off, the abnormal state that the whole bus network vehicle cannot enter the dormancy state or the vehicle is frequently awakened can be effectively monitored.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and more particularly relates to a method and system for monitoring abnormality of a vehicle bus network. Background technique [0002] There are a variety of cooperative control units in the automotive system. At present, the communication methods between the control units mainly include CAN, Flexray, and vehicle Ethernet. The process that the automotive electronic system configures and manages all the control units and coordinates the work through the vehicle network is called network management. [0003] Network management, that is, when the vehicle is powered off, all control units on the bus are in a low power consumption state to reduce vehicle battery consumption. Network management is generally used in battery-powered control units, such as body controllers, instrumentation, etc. Assuming that after the power is turned off, the vehicle bus network cannot sleep within the specifi...
