面向下一代汽车的汽车软件更新

未披露

一家德国商用电动汽车制造商管理着一大批通常位于城市地区的车辆。为了更好的驾驶体验和安全，汽车软件更新安装在任何情况下都不应失败，因为没有人员来修复它。

一家德国商用电动汽车制造商希望通过使用无线 (OTA) 重复来确保及时、安全地交付关键的汽车软件更新。

即使 Wi-Fi 不可用，及时提供关键更新也非常重要。由于大量车辆通常位于城市地区，因此需要一种解决方案来避免蜂窝网络过载。

Tietoevry 的汽车团队开发了无线 (OTA) 解决方案的概念，该解决方案允许通过无线网络分发软件更新，而无需物理访问车辆。

制造商可以远程向车辆提供固件更新、补丁、软件和数据更新，从而无需驾驶员联系经销商或维修店。

• The implementation of the OTA solution has resulted in a more efficient and reliable system for delivering critical automotive software updates. The solution has eliminated the need for physical access to vehicles for software updates, thereby reducing the inconvenience for drivers and the need for them to contact a dealer or a repair shop. The solution has also improved the security of vehicle-to-cloud communications, ensuring the authenticity, integrity, and confidentiality of these communications. Furthermore, the solution has enhanced the reliability of software update installations, with the system designed to roll back to the previous state in case of any interruptions. This has ensured that the software update installations do not fail under any conditions.

• Cost-effective software maintenance through remote management of automotive software of a large fleet of cars using Wi-Fi, LTE, or 3G.
• Improved vehicle security through the developed algorithm that guarantees authenticity, integrity, and confidentiality.
• Enhanced driver satisfaction and brand loyalty through remote software and data updates.
