Problems solved by technology
At present, in the process of vehicle troubleshooting, the general troubleshooting method has a long period of troubleshooting, and it is difficult to find the root cause. If the troubleshooting is not timely, CAN bus error frames will not only lead to poor real-time communication problems, but also report various problems. Communication failures, even causing the CAN bus to fail to work
Therefore, there is an urgent need for a device and method for troubleshooting CAN bus error frames in a vehicle, which can solve the problem of long troubleshooting period and difficulty in finding the root cause, thereby shortening the vehicle development cycle

The invention provides a checking device and a checking method for a full vehicle CAN (Controller Area Network) bus error frame, and relates to the field of error frame detection. The checking methodcomprises the steps of: when an error frame is detected on a CAN bus, determining a network segment where the error frame is detected; acquiring a network segment basic attribute of the error frame network segment, and judging whether the network segment basic attribute of the error frame network segment satisfies a preset condition; and when the network segment basic attribute of the error framenetwork segment does not satisfy the preset condition, prompting that the network segment basic attribute of the error frame network segment has an error. The error frame checking efficiency can be improved via the complete and systematic checking method, so that the full vehicle development period is shortened.
Description
technical field [0001] The invention relates to the technical field of error frame checking, in particular to a device and method for checking error frames of a vehicle CAN bus. Background technique [0002] In today's society, many faults often occur during the production and manufacturing process of automobiles. At present, in the process of vehicle troubleshooting, the general troubleshooting method has a long period of troubleshooting, and it is difficult to find the root cause. If the troubleshooting is not timely, CAN bus error frames will not only lead to poor real-time communication problems, but also report various problems. Communication failures may even cause the CAN bus to fail to work. Therefore, there is an urgent need for a device and method for troubleshooting CAN bus error frames in a vehicle, which can solve the problems of long troubleshooting period and difficulty in finding the root cause, thereby shortening the vehicle research and development period....
