AI Technical Summary
Existing autonomous driving systems lack effective countermeasures when the calculation results of the main chip and the sub-chip are inconsistent or when a single point of failure occurs, thus failing to ensure driver safety.
It adopts a dual-chip-layer structure, including a first system-level chip layer and a second system-level chip layer. The calculation results are verified by a fusion verification module and a planning verification module. In case of failure, it switches to a redundant control module to ensure safe driving and uses backup sensors for redundant control.
In the event of system failure or chip inconsistency, the driving level can be automatically reduced to Level 2 to ensure safe driving. The redundant control system prompts the driver to take over, improving system safety and driving experience.
