[0049] See figure 1 The flowchart of the OTA upgrade method according to the first embodiment of the present invention is applied to the gateway of the vehicle, and the OTA upgrade method includes steps S01 to S03.

[0050] S01: Gets the wake-up request sent by the in-vehicle communication module, and makes itself a wake-up state based on the wake-up request, the wake-up request, which is sent to the vehicle communication module during receiving the external OTA upgrade request;

[0051] Among them, the in-vehicle communication module is specifically car T-Box, that is, the vehicle network terminal, which is equivalent to the host control system on the automobile, can be connected via a network and a variety of terminal networks to control the electronic equipment inside.

[0052] It should be noted that the wake-up request is specifically manifested: When the vehicle communication module receives an external OTA upgrade request, trigger itself to enter the repeated transmission s...

[0064] See image 3 , OTA upgrade method shown in the second embodiment of the present invention, which is applied to the vehicle gateway, the method comprising the step of OTA upgrade S11 to Step S21:

[0065] S11: obtaining wakeup request sent by the vehicle-mounted communication module, and make their own according to the wakeup request is awake, the wake-up request is sent to the vehicle communication module upon receipt of an external OTA upgrade request;

[0066] S12: acquiring the in-vehicle communication module to transmit the predetermined normal cycle packets to enter the normal mode of operation, and starts a first timer;

[0067] It will be appreciated, the wake-up process in the gateway, the communication module when the detected vehicle drops to zero or to a preset number when the second timer times out, then the vehicle-mounted communication module enters the normal operation mode and changed to the normal cycle transmits messages to the gateway the gateway also ente...

[0091] Further aspect the present invention provides a system OTA upgrade, see Figure 4 The OTA upgrade the system include:

[0092] Active Wake Wake Control Module 10: Used to obtain a wake-up request sent by the in-vehicle communication module, and make itself a wake-up state based on the wake-up request, the wake-up request, which is sent to the vehicle communication module to receive the external OTA upgrade request;

[0093] Getting Module 11: Used to obtain the preset packet sent by the in-vehicle communication module at a normal cycle to enter the conventional mode of operation, and start the first timer;

[0094] Timing Reset Module 12: After each of the preset packets transmitted by the in-vehicle communication module, reset the first timer to restart the timing;

[0095] Sleep Module 13: Used to release the CAN network at which the first timer is detected greater than or equal to the first preset time, release the CAN network to be upgraded to enter sleep mode;

Abstract

The invention provides an OTA upgrading method and system, a readable storage medium and a vehicle, and the method comprises the steps: obtaining a wake-up request sent by a vehicle-mounted communication module, and enabling the vehicle-mounted communication module to be in a wake-up state according to the wake-up request; requesting the vehicle-mounted communication module to send upgrading data of a to-be-upgraded module; when the upgrading data of the to-be-upgraded module is received, awakening the CAN network where the to-be-upgraded module is located according to the upgrading data of the to-be-upgraded module, and sending the upgrading data to the currently awakened CAN network. According to the OTA upgrading method provided by the invention, the CAN network where the to-be-upgraded module is located is specifically awakened, so that the whole vehicle network is effectively prevented from being awakened, the load rate on the bus is greatly reduced, the OTA upgrading rate is favorably improved, and the whole vehicle cost is reduced.

Description

Technical field [0001] The present invention relates to the field of automotive OTA upgrades, and in particular, to an OTA upgrade method, a system, a readable storage medium, and a vehicle. Background technique [0002] With the continuous development of electricity, intelligence, netization, sharing of automobiles, the function of automobile ECU is also more powerful, and in the intelligent processing of the vehicle, it is usually necessary to process information through the cloud and vehicle cooperation. For the upgrade process of the automobile ECU, you need to get an upgrade package, which in turn brushes the upgrade processing according to the upgrade package. [0003] In the prior art, vehicles generally realize the online update upgrade of system software through a more advanced air refermeter OTA, to achieve software, hardware implementation, download, code update, etc. . [0004] However, when the vehicle is upgraded to the vehicle, since the network of the whole vehicl...
