Next-Generation AK2 Ultrasonic Radar: The Core Perception Component Defining New Standards in Intelligent Driving

In an era of rapid advancements in intelligent driving and automation technologies, precise environmental perception forms the foundation of all advanced vehicle functions.

The next-generation AK2 ultrasonic radar has been developed to meet this demand. Based on ultrasonic ranging principles, this new-generation intelligent sensor features extended detection range, minimized blind zones, and exceptional interference immunity—positioning it as a key perception component for next-generation intelligent driving systems.

Comprehensive Performance Upgrade

AK2 represents a significant leap beyond conventional ultrasonic technologies. It achieves a maximum detection range of up to 550 cm, while substantially reducing near-field blind spots.

This capability provides vehicles with unprecedented spatial awareness. Whether for long-distance obstacle pre-warning or ultra-close precision measurement in complex scenarios such as automated parking and low-speed obstacle avoidance, AK2 delivers stable and reliable performance—safeguarding safe vehicle operation under all conditions.

Advanced Communication Architecture: DSI3 Protocol

One of the product’s core competitive advantages lies in its adoption of the industry-leading DSI3 communication protocol.

DSI3 supports high-speed synchronous data transmission and effectively eliminates same-frequency interference between multiple ultrasonic sensors. In modern vehicles equipped with an increasing number of sensors, this technology ensures clean, synchronized, and real-time perception data.

The result is a highly reliable and tightly fused environmental model, providing robust input for vehicle decision-making and control systems.

High-Performance Chipset Architecture

At the hardware level, AK2 is powered by a strong chipset combination consisting of:

• Elmos 524.17 / 524.20

• Onsemi RDU5

These industry-leading semiconductor solutions provide superior signal processing capability, operational stability, and environmental robustness. This advanced hardware architecture ensures top-tier system performance and long-term reliability.

High-Precision Perception for ADAS and Autonomous Driving

With a ranging accuracy of ±3 cm, AK2 meets the stringent perception requirements of ADAS (Advanced Driver Assistance Systems) and autonomous driving applications.

Its data can be deeply fused with inputs from cameras, millimeter-wave radars, and other sensing technologies to construct a comprehensive 360-degree perception network around the vehicle. This multi-sensor integration establishes a solid foundation for higher-level intelligent driving functions.

A Core Component for the Future of Mobility

AK2 ultrasonic radar is more than just a sensor—it is a core perception module designed for the future of mobility.

With extended “vision,” clearer near-field perception, and smarter collaborative capabilities, AK2 plays a critical role in enhancing the safety, reliability, and scalability of intelligent driving systems.

As automotive intelligence continues to evolve, AK2 will leverage its advanced perception technology to safeguard every intelligent journey.
