SOTA can actually be regarded as the core requirement of a software sales strategy. It implements an “incremental” update of the controller function by installing an “incremental package” on the vehicle controller. It is generally used in entertainment systems and smart driving systems. . For example, when replacing the operation interface of the multimedia system, optimizing the display style of the instrument panel, and updating the map program in the entertainment console, the SOTA upgrade method is used. SOTA involves a small-scale partial update of the functions of the controller application layer, which has little impact on the performance of the vehicle and requires relatively low pre-conditions for the upgrade. SOTA’s incremental update strategy can greatly reduce the size of the upgrade package file, thereby saving network traffic and storage space.
For example, to upgrade the smart driving car system, in order to allow drivers to enjoy more and more assisted driving functions; usually according to the difficulty of function development and the length of time to determine the continuous update and iteration of phased functions (including from low-level functions to high-level functions) order of software change). At the same time, the cockpit system of the vehicle needs to be upgraded in the process to improve the accuracy of driver fatigue detection; the associated subsystems of the intelligent driving vehicle (such as braking, steering system and other modules) should be upgraded to improve the braking performance of the vehicle.
