1、China ADAS Redundant System Strategy Research Report,2024D Redundant system strategy research:develop towards integrated redundant designRedundant system strategy research:develop towards integrated redundant designADAS redundant system definition frameworkFor autonomous vehicles,safety is the prima

2、ry premise.Only when ADAS is fully redundant can real safety be ensured.Currently,the redundant design of most OEMs,Tier 1 suppliers and L4 autonomous driving companies is mainly software and hardware backup:Software:algorithm redundancy,for example,GAC Groups latest ADiGO PILOT intelligent driving

3、system adopts the AEB function algorithm,the vision+radar fusion algorithm and the vision algorithm real-time redundant verification strategy to maximize the reliability of AEB.Hardware:reflected in different functional positions.The perception end,decision end,execution end,power supply end,etc.all

4、 adopt dual-redundant or multi-redundant design to ensure that when one of the systems fails,another system with the same function can work Execution redundancy:Fully redundant design of braking and steering systemsExecution redundancy:Fully redundant design of braking and steering systemsExecution

5、redundancy and decision redundancy are the core parts,directly determining whether the vehicle can make correct response at a critical moment.Execution redundancy is often placed in braking and steering systems,and is generally designed as two independent systems with same functions.Decision redunda

6、ncy is on the brain side.In vehicle EEA,the central computing platform is equipped with two sets of core computing units,and the redundant architecture design concept is adopted at vehicle architecture level,function definition level,system level,etc.From the perspective of braking redundancy,its ch
