Recently, Tesla officially unveiled that its AI4 hardware for intelligent driving assistance now incorporates a comprehensive failover redundancy architecture. In this setup, dual computing units function in parallel while continuously conducting bidirectional monitoring of each other. Should either system encounter a malfunction, the other can seamlessly assume control within milliseconds, thereby guaranteeing the unwavering stability of the vehicle’s core functions. This design marks a significant departure from conventional redundancy solutions in automotive electronics, achieving full-link isolation and independence to effectively prevent systemic fault propagation at its source.
