Abstract: With the continuous improvement of the level of automotive electronics, the upgrade and iteration of on-board controller software are becoming more and more frequent in automotive electronic systems, which is extremely important for enhancing the intelligence of automobiles and improving user experience. However, traditional instrument controllers usually do not have remote upgrade functions and are difficult to meet the needs of rapid iteration. Therefore, in response to this problem, this paper proposes a remote automotive technology upgrade scheme that combines stability, convenience and safety. This scheme makes full use of the mature upgrade mechanism of the intelligent cockpit system, integrates the traditional instrument controller with the intelligent cockpit system, and successfully realizes the remote update of the instrument controller system through wireless networks. Real vehicle tests show that this technical scheme is feasible, safe and reliable, indicating that over the air (OTA) technology will usher in rapid development.
