- DrivebuddyAI received an Indian patent for a self-calibrating lane ROI detection system that improves ADAS accuracy.
- The technology supports real-time safety functions and autonomous driving applications across diverse road conditions.
DrivebuddyAI, a developer of AI-powered Advanced Driver Assistance Systems (ADAS) and Driver Monitoring Systems (DMS), has obtained an Indian patent for a real-time lane region-of-interest (ROI) detection technology aimed at improving the reliability and precision of vehicle safety functions. The patented innovation is designed to address critical limitations in existing lane detection systems by enabling automatic calibration and optimisation without requiring manual adjustments during deployment or operation.
Conventional ADAS solutions often experience reduced lane detection performance due to differences in camera mounting angles, vehicle architecture, road layouts, and changing environmental conditions. These inconsistencies can result in false warnings or missed alerts, potentially affecting vehicle safety. DrivebuddyAI's patented framework addresses these challenges through a self-calibrating mechanism that automatically refines lane calculations during fresh installations, software upgrades, and system restarts, helping maintain dependable system performance over time.
The technology combines AI-based frame validation, vehicle-specific lane adaptation, and a dual-camera configuration that merges road-facing ADAS functionality with driver monitoring capabilities. This integrated architecture supports several safety-focused applications, including lane departure warnings, collision avoidance functions, and steering assistance systems. The company states that the solution is compatible with Level 2 and Level 3 autonomous driving applications, including Autonomous Emergency Braking (AEB) and advanced path-planning functions.
Unlike traditional static calibration methods, the patented system continuously evaluates and updates lane ROI parameters using live driving information. This dynamic approach allows the technology to maintain consistent performance across challenging scenarios such as faded lane markings, poor weather conditions, low-light environments, and complex mixed-traffic situations commonly encountered on public roads.
The company reported that the technology has been trained and validated using more than 6.4 billion kilometres of real-world driving data collected from highways, urban corridors, rural roads, and diverse traffic environments. Cloud connectivity and over-the-air software update capabilities further support continuous optimisation, enabling performance improvements across commercial vehicle fleets and original equipment manufacturer deployments.
The latest patent strengthens the intellectual property portfolio of DrivebuddyAI, which the company says now includes more than 15 granted patents covering ADAS, DMS, AI perception technologies, driver risk assessment, driver recognition, and intelligent mobility solutions. Headquartered in Ahmedabad, India, the company operates as a group entity of Roadzen Inc., which is listed on Nasdaq under the ticker RDZN.
