Differential ota delta compression: BYDRecent Research Landscape

Incomplete software overwrites during remote updates cause system bricking and vehicle downtime. These innovations utilize partitioned memory and delta-patching to ensure fail-safe execution and recovery.

What technical problems is BYD addressing in Differential ota delta compression?

Unreliable remote update connectivity

(28)evidences

Limited communication throughput and storage capacity in embedded systems delay critical software deployments. Reducing data transmission volume prevents system downtime and minimizes network congestion during remote updates.

Unreliable remote software synchronization

(20)evidences

Interrupted or corrupted data transfers during over-the-air updates lead to vehicle immobilization. Ensuring atomic and reliable updates prevents critical system failures during remote maintenance.
