Vehicle ECU upgrading control method

Abstract

The invention discloses a vehicle ECU upgrading control method. The method comprises the following steps: firstly, when a T-box receives a signal that an ECU needs to be updated from a cloud server, the T-box downloads the engine data to the ECU through the cloud server and sends an upgrading request to the vehicle instrument; after the vehicle instrument receives the upgrading request, whether the vehicle condition meets an upgrading condition or not is judged, when the vehicle condition meets the upgrading condition, an instrument display screen displays that an ECU can be upgraded, and finally a user completes ECU upgrading through man-machine interaction. According to the method, the time of waiting for ECU upgrading by the user is remarkably shortened, the participation degree and theperceptibility of the user are improved, and the driving safety is not influenced.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a vehicle ECU upgrade control method, which is suitable for reducing the time for users to wait for the vehicle ECU upgrade. Background technique [0002] At present, when the vehicle controller is upgraded on a commercial vehicle, the user cannot obtain relevant upgrade information through the vehicle instrument, and when the vehicle instrument itself is updated, the user does not participate in the upgrade process. When the device is updated, it is not only easy to cause the upgrade to fail due to user operations, but also to upgrade during driving, which is likely to cause safety problems. [0003] Chinese patent: Authorized public number CN108454538A, the invention of the authorized announcement date on August 28, 2018 discloses a vehicle electronic control unit refresh system, including a vehicle machine, a gateway and a vehicle electronic control ...

Problems solved by technology

[0002] At present, when the vehicle controller is upgraded on a commercial vehicle, the user cannot obtain relevant upgrade information through the vehicle instrument, and when the vehicle instrument itself is updated, the user does not participate in the upgrade process. Since the user cannot know the status of the vehicle controller, when the vehicle controller is updated, it is not only easy to cause the upgrade to fail due to user operations, but also to upgrade during driving, which is likely to cause safety problems

[0003] Chinese patent: authorized public number CN108454538A, authorized announcement date August 28, 2018 The invention discloses a vehicle electronic control unit refresh system, including installation on the vehicle The car machine, gateway and vehicle electronic control unit, the car machine includes a wireless communication module and the human-machine interface, the car machine obtains the ECU software package of each vehicle electronic control unit from the wireless communication network through the wireless communication module, and the gateway performs reliable monitoring of the car machine. If the reliability verification of the car machine is passed, use the more advanced version of the ECU software package of the vehicle electronic control unit in the car machine to update the current ECU software package of the corresponding vehicle electronic control unit in the gateway. After the gateway obtains the vehicle condition information through the bus, If the vehicle condition meets the refresh condition of the vehicle electronic control unit and receives the upgrade request signal from the vehicle, the gateway will send the current ECU software package data of each vehicle electronic control unit to the corresponding vehicle electronic control unit, although this method can not only reduce the Labor costs, and can ensure the safety of the vehicle electronic control unit refresh, but in this method, the gateway obtains the ECU software package from the vehicle only after the reliability verification of the vehicle is passed, and the gateway only updates the current ECU in it when the user requests an upgrade. The software package is downloaded to the vehicle electronic control unit and then the upgrade is completed. The download process takes a long time, and the user must wait for a long time to complete the ECU upgrade

Therefore, there is a problem that the user waits for a long time for the ECU upgrade
