[0050] The embodiment of the present invention provides a method for storing fault information, such as figure 1 shown, including:

[0051] S101. Detect the data volume of fault information currently to be stored.

[0052]In the embodiment of the present invention, it can be detected in real time or periodically whether there is currently fault information to be stored, and the data volume of the fault information to be stored.

[0053] S102. Detect the remaining capacity of the first storage area in the random access memory of the vehicle for storing fault information.

[0054] In the embodiment of the present invention, after detecting that there is currently fault information that needs to be stored, it is possible to detect the remaining capacity of the first storage area of ​​the automobile random access memory (RAM) for storing fault information, so as to determine the remaining capacity of the first storage area. Whether the capacity can store the current fault inform...

[0075] The embodiment of the present invention provides a device for storing fault information, such as image 3 shown, including:

[0076] The first detection module 301 is configured to detect the data volume of fault information currently to be stored.

[0077] In the embodiment of the present invention, the first detection module 301 can detect in real time or periodically whether there is currently fault information to be stored, and the data volume of the fault information to be stored.

[0078] The second detection module 302 is configured to detect the remaining capacity of the first storage area used to store fault information in the random access memory of the vehicle.

[0079] In the embodiment of the present invention, after the first detection module 301 detects that there is currently fault information that needs to be stored, the second detection module 302 detects the location of the first storage area of ​​the automobile random access memory (hereinafter refe...

Abstract

The invention provides a fault information storage method and device. The method comprises the steps of detecting the data volume of fault information needed to be stored currently; checking the remained space of a first storage area for storing fault information in the random access memory in a vehicle; If the difference between the data volume of the fault information to be stored currently and the remained space of the first storage area is larger than or equal to a first preset value and smaller than a second preset value, the stored fault information in the first storage area is partially or wholly transferred to a read-only EEPROM which is both electrically erasable and programmable, and fault information needing to be stored currently is transferred to and stored in the first storage area. The technical scheme not only can wholly record the existent information of the faults which already occur, but also can timely store the fault information of newly emerged faults, thereby enhancing the utilization rate of the storage space.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for storing fault information. Background technique [0002] In the face of increasingly severe energy and environmental problems, energy-saving and new energy vehicles are becoming the focus of current research in various countries. As a type of energy-saving and new energy vehicles, pure electric vehicles have many advantages such as no exhaust emissions, high energy efficiency, low noise, and energy recycling during driving. With the rapid development of pure electric vehicles, integrated control has become the current development trend of pure electric vehicles. Integrated control, as the name suggests, relies on the powerful computing power of the microprocessor at this stage, rich functions and external resources, effectively integrates individual controllers responsible for different functions, and realizes the original control by multiple independ...
