AK2 Ultrasonic Radar: The Source of Accurate Perception for Autonomous Driving and Low-Speed Cruise Control

Today, with the rapid development of autonomous driving technology, the low-speed cruise system, as an important part of the autonomous driving function, is of great importance to the safe driving of vehicles. In this system, the role of sensors is particularly prominent, as they are the key to the vehicle's perception of the surrounding environment and automatic obstacle avoidance. With its excellent performance, the AK2 ultrasonic radar is becoming one of the indispensable sensors in the autonomous driving low-speed cruise system.

Technical features of AK2 ultrasonic radar

Ultra-long detection distance

The detection distance of Audi AK2 ultrasonic radar can reach 7 meters, which enables it to provide a greater safety distance for vehicles in low-speed cruise systems, so as to detect obstacles or other vehicles earlier. This is especially important in crowded urban environments and can effectively prevent collision accidents.

Extremely small detection blind spot

The AK2 radar has a detection blind spot as small as 15cm, which means it can sense obstacles at close range more accurately, reducing the risk of collision. This feature is crucial for safety when driving at low speeds, especially in narrow parking lots or congested roads.

Coded FM capability

AK2 radar supports frequency modulation and can switch between long and short distance measurement, which makes it highly adaptable in different parking and low-speed driving scenarios. Through the unique ultrasonic signal encoding method, AK2 radar can send different ultrasonic signals at the same time, greatly shortening the system refresh cycle and improving system efficiency.

Fast refresh duration

The refresh time of AK2 radar is shorter than 40ms, which ensures that it can respond to changes in the surrounding environment in real time during low-speed cruising. Fast response time is crucial for the decision-making of autonomous driving systems in complex traffic environments.

Multi-mode switching support

AK2 radar can carry multiple sensors to work synchronously, and has a variety of coding settings and fixed frequency settings. It can control the working mode of the sensor according to different functional requirements. This flexibility enables AK2 radar to adapt to various different autonomous driving application scenarios.

Self-diagnosis function

AK2 radar has a self-diagnosis function that can quickly detect signal transmission and reception in real time, ensuring safe operation even in small or complex environments. This self-diagnosis function provides additional protection for the reliability of the autonomous driving system.

Meeting functional safety requirements

The AK2 radar meets the functional safety ASIL-B level requirements, meets the automotive industry's high safety standards, and provides additional safety protection for low-speed cruising.

Application of AK2 ultrasonic radar in low-speed cruise system

In the low-speed cruise system, AK2 ultrasonic radar can be used in the following scenarios:

Obstacle Detection

When the vehicle is driving at low speed, the AK2 radar can detect obstacles ahead in real time and provide accurate distance information to the autonomous driving system, thereby achieving automatic obstacle avoidance.

Parking assistance

During the automatic parking process, the AK2 radar can help the vehicle accurately identify the location and size of the parking space and achieve precise parking.

Following at low speed

In congested urban traffic, the AK2 radar can assist the vehicle in achieving low-speed following function and maintaining a safe distance from the vehicle in front.

Pedestrian Detection

When driving at low speeds, the AK2 radar can also be used to detect pedestrians around the vehicle to improve pedestrian safety.

AK2 ultrasonic radar provides strong technical support for the autonomous driving low-speed cruise system with its ultra-long detection distance, extremely small detection blind area, coding frequency modulation capability, fast refresh time, multi-mode switching support, self-diagnosis function and functional safety requirements. With the continuous advancement of autonomous driving technology, AK2 ultrasonic radar is expected to play a more critical role in the future intelligent transportation field, providing a higher level of safety for low-speed driving.
