On August 11th, we learned from the official press that Buick Arrival OS 2.1 was officially launched. This OTA upgrade covers all models in the country, including the addition and optimization of many functions such as advanced assisted driving and smart cockpit. OTA push is now enabled for Zhijie Family, and the push is expected to start in August for Zhijie E7 and Zhijie L7. In terms of assisted driving, scenarios such as smart-painted parking, unmarked open spaces, old parking lots or campgrounds have been added. The car and machine can be freely dragged and parked in one-click automatic parking. The AES automatic emergency steering function can cope with unexpected risks and accurately judge. The driving assisted self-recovery function encounters temporary avoidance and detour during high-speed pilotage. The system can automatically resume NOP pilotage assistance at any time after the driver completes the operation. The AEB recognition ability adds a variety of special-shaped obstacles to cover complex targets such as cardboard boxes, triangular cards, cone buckets, and water horses. In terms of the smart cockpit, a sentence has been added to customize the scene, 10 + functional modules, 20 + optional trigger conditions, and no cumbersome settings and operations need only a password; the AI Agent Butler is online to proactively provide comfort and care in advance, recognize voiceprints and remember your habits; Sentinel Mode 360 is viewed remotely, and if you receive a risk reminder without getting on board, you can check the outside of the car in real time, quickly eliminate risk events and eliminate anxiety with more peace of mind. From the existing Apple CarPlay to the extensive coverage of Huawei and Android camps. Zhijie Shijiazhuang added 15 functions such as smart parking, AES automatic emergency steering, narrow road flexible turnaround, Carlink, HiCar, etc., and optimized the capabilities of 14 scenarios; Zhijie L7 added 8 functions and optimized the capabilities of 9 scenarios; Zhijie E7 added 5 functions and optimized the capabilities of 10 scenarios.
