Example Embodiment

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] This embodiment provides a data recording method based on a T-BOX containing two pieces of memory. For the data recording method, see figure 1 , Including steps:

[0037] S11: Receive the vehicle operating state data, and add a time stamp to the vehicle operating state data according to the time when the vehicle operating state data is received.

[0038] In this embodiment, the vehicle operating state data is CAN, CANFD and / or LIN com...

Abstract

The invention provides a data recording method and device, a memory and T-BOX, the method is based on a T-BOX comprising two memory slices, the data stream is directly written into the memory, the writing speed is high compared with that of writing in a disk, writing of the data stream is not interrupted due to the arrangement of the two memories, data loss is reduced, and the integrity of data records is improved. After data compression, the data volume is smaller than that without compression, so that the data is written into the disk after being compressed, and the time for writing the datainto the disk is shortened; Compared with file compression, the process of reading the data from the disk is reduced, and the system overhead is reduced. Furthermore, the data format is converted into the binary format, so that the compression efficiency is improved, and the disk occupation is reduced. And the data is uploaded in real time, so that the running state of the vehicle can be known intime.

Description

technical field [0001] The present invention relates to the field of T-BOX, more specifically, relates to a data recording method, device, memory and T-BOX. Background technique [0002] When vehicle manufacturers conduct road condition tests on vehicles, they need to monitor the vehicle's operating status data. For example, test road conditions such as high and low temperature, high and low altitude, flat roads, mountain roads and bumpy roads. During the entire driving process of the vehicle, use T-BOX (Telematics BOX, telematics processor) to record and save the data when the vehicle is running. After the run is over, the data is copied out for analysis. Data records based on T-BOX are currently mainly for CAN (ControllerArea Network, controller area network) / CANFD (Controller Area Network with Flexible Datarate) communication messages and LIN (Local Interconnect Network, local area interconnection network) communication messages data records. Both CAN / CANFD communicati...
