Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] At present, network technology and mobile devices have developed very maturely, such as widely used "cloud" technology, mobile phone Apple, Android and Windows systems. At the same time, the existing technology has realized the standardization of vehicle ECU, the generalization of flashing software process, the standardization of bus communication technology, and the wireless network technology is very mature. Based on this, the present invention proposes a device for flashing ECUs of various vehicle-mounted electronic devices, thereby greatly reducing the cost of flashing various ECUs, and providing users with an experience of self-updating the vehicle-mounted system.

[0019] Such as figure 1 Shown is a schematic structural diagram of the vehicle-mounted device remote flashing device of the present invention, the vehicle-mounted devic...

Abstract

The invention provides remote writing equipment of an OBD (On-Board Device) and belongs to the technical field of automobile electronics. The equipment comprises a wireless communication module used for realizing communication with an operation terminal, a main control module connected with the wireless communication module and used for controlling operation of the equipment, a storage module connected with the main control module and used for storing information required to be stored for the equipment, an on-board data conversion module connected with the main control module and an OBD interface module connected with the on-board data conversion module, wherein the on-board data conversion module is used for converting data or on-board data of the equipment and realizing communication between the equipment and a vehicle; the OBD interface module is used for realizing data interaction between the on-board data conversion module and the OBD interface of the connected vehicle. The remote writing equipment provided by the invention can be used for not only rapidly and correctly writing data into an ECU (Electronic Control Unit) and ensuring the high efficiency and reliability of a writing process, but also realizing automatic on-board software upgrading for users.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and relates to a flashing technology for a vehicle-mounted device. Background technique [0002] With the development of vehicle-mounted intelligent systems, there are more and more electronic control units (ECUs) on vehicles, and there are various types of ECUs. In order to save costs, automobile manufacturers and auto parts suppliers hope to use fewer ECUs. hardware to perform more functions. Therefore, different software can be flashed on the same ECU hardware to achieve multi-functional and multi-platform applications. [0003] The current ECU software flashing equipment is limited to automobile and parts production bases and 4S after-sales service centers. These equipment are expensive, bulky, and difficult to upgrade software. Even manufacturers are facing problems such as high investment costs and difficult software upgrades. Therefore, it is of great application value and...
