Connected cockpits multiply attack surfaces—from Bluetooth stacks to cloud APIs—forcing compliance with UNECE WP.29 and ISO/SAE 21434 security-by-design mandates. Biometric multi-factor entry systems reduce relay-attack theft but add encryption overhead and certification fees. Vehicles could generate up to 10 exabytes of data monthly by 2025, amplifying storage and anonymization burdens. Smaller vendors lacking cipher expertise face higher homologation friction, accelerating consolidation toward security-mature tier-1s.

Segment Analysis

By Product Type: Central Displays Consolidate Control Architecture

Central displays secured 42.1% revenue in 2024 as OEMs converged HVAC, navigation, and media controls into single-pane cockpits that lower wiring weight and standardize software maintenance. The Automotive human machine interface market size for central displays is projected to climb at 8.9% CAGR through 2030, buoyed by rising 15-inch diagonal demand in mass-segment SUVs. Although starting from a lower base, AR-HUDs accelerate at 17.1% CAGR as regulatory nudges push critical warnings into the driver’s sight line, a trend most pronounced in Level 3 pilot programs launched by German premium brands. 

AR-HUD adoption compels optical suppliers to refine waveguide uniformity and reduce windshield ghosting, while projector makers shift to micro-LED to gain daylight brightness without enlarging combiner boxes. Voice control modules retain 42.5% share thanks to privacy-preserving edge processing that keeps latency under 150 milliseconds. Gesture-control sensors grow 16.1% annually as the cost of ToF cameras dips below USD 12 per unit, though mainstream adoption still hinges on clear value beyond novelty.
