AK2 Ultrasonic Radar: The Precision Sensing Solution for Low-Speed Cruise in Autonomous Driving

With the rapid advancement of autonomous driving technology, low-speed cruise systems have become essential to ensuring safe vehicle operation. Sensors are especially crucial in this system, enabling the vehicle to perceive its surroundings and avoid obstacles. The AK2 ultrasonic radar, with its outstanding performance, has become an indispensable sensor in low-speed cruise systems for autonomous vehicles.

Key Technical Features of the AK2 Ultrasonic Radar

Extended Detection Range
The ADW AK2 radar has a detection range of up to 7 meters, providing a greater safety margin to detect obstacles or other vehicles early. This feature is particularly useful in crowded urban environments, helping to prevent collisions effectively.

Minimal Detection Blind Zone
With a blind zone as small as 15 cm, the AK2 radar can precisely sense nearby obstacles, reducing the risk of collisions. This is especially vital for safety during low-speed travel, such as in narrow parking lots or congested streets.

Frequency Modulation Capability
Supporting frequency modulation, the AK2 radar allows seamless switching between long-range and short-range detection, making it highly adaptable in various low-speed driving and parking scenarios. Using unique ultrasonic signal encoding, it can send multiple signals simultaneously, shortening the system refresh cycle and enhancing efficiency.

Fast Refresh Rate
With a refresh time of less than 40 ms, the AK2 radar ensures real-time responsiveness to environmental changes in low-speed cruising. This rapid response is crucial for autonomous decision-making in complex traffic situations.

Support for Multi-Mode Switching
The AK2 radar supports multiple sensors working in sync, with various coding and frequency settings to adjust the sensor mode based on different functional requirements. This flexibility allows it to adapt to a wide range of autonomous driving applications.

Self-Diagnostic Functionality
The AK2 radar includes a self-diagnostic feature that quickly detects signal transmission and reception, ensuring safe operation even in tight or complex environments. This adds an extra layer of reliability to autonomous driving systems.

Functional Safety Compliance
Meeting ASIL-B functional safety standards, the AK2 radar adheres to the automotive industry’s stringent safety requirements, providing an added layer of safety in low-speed cruise scenarios.

Applications of the AK2 Ultrasonic Radar in Low-Speed Cruise Systems

Obstacle Detection
During low-speed driving, the AK2 radar detects obstacles in real time, providing the autonomous system with accurate distance data to enable automatic obstacle avoidance.

Parking Assistance
The AK2 radar aids in precisely identifying parking space dimensions and positioning, facilitating accurate parking.

Low-Speed Following
In congested urban traffic, the AK2 radar assists vehicles in maintaining a safe following distance at low speeds.

Pedestrian Detection
While moving at low speeds, the AK2 radar detects pedestrians around the vehicle, enhancing pedestrian safety.

With features like an extended detection range, minimal blind zones, frequency modulation, fast refresh rates, multi-mode support, self-diagnostics, and compliance with functional safety requirements, the AK2 ultrasonic radar provides robust support for low-speed autonomous cruise systems. As autonomous driving continues to evolve, the AK2 radar is expected to play a pivotal role in the future of smart transportation, offering advanced safety for low-speed driving scenarios.
