AUTOSAR Classic Methodology and Example Code to Simplify Over-the-Air Software Update Implementation
Over-the-air software updates are one of the important technology trends in the modern automotive industry. AUTOSAR (AUTomotive Open System ARchitecture) Classic is a standardized platform for the development of automotive-oriented electronic systems, which provides a reliable and scalable framework to help developers successfully implement over-the-air software updates. This article will share how to use AUTOSAR Classic to implement wireless software updates, and provide corresponding sample codes.
-
Determine hardware and network support: First, make sure the vehicle's hardware and communications network supports over-the-air software updates. Common wireless communication technologies include Bluetooth, Wi-Fi and mobile networks such as 3G, 4G or 5G. Make sure that the electronic control unit (ECU) on the vehicle has a module that supports the appropriate wireless communication technology.
-
Configure AUTOSAR Classic: Use the development environment of AUTOSAR Classic to configure software components and services according to the needs of the vehicle. AUTOSAR Classic provides a hierarchical structure based on software components to support modular development and reuse. Select and configure corresponding components as required, such as communication modules, storage modules, and diagnostic modules.
-
Realize the wireless communication function: use the relevant components and services of AUTOSAR Classic to realize the wireless communication function. For example, a communication module can be utilized to establish a communication link between the vehicle and an external server. These modules provide corresponding interfaces and protocols to ensure reliable data transmission.
Below is a sample code for Wi-Fi based wireless software update using AUTOSAR Communication Stack:
