This new car has eight ultrasonic radars

The new SUV car shown in the picture below will be launched in 2024. In terms of safety and intelligent driving capabilities, the 2024 Xingyue L is equipped with five external cameras and eight ultrasonic radars, but the millimeter-wave radar is cancelled.

Many car enthusiasts have raised questions about this: Why would this new car prefer to cancel the millimeter-wave radar and retain the ultrasonic radar?

This is closely related to the iteration of ultrasonic radar technology and the improvement of the capabilities of the "ultrasonic + vision" solution in recent years. As smart cars and autonomous driving technologies are developing rapidly, ultrasonic radar, as one of the key sensors, is playing an increasingly important role. This article will deeply analyze the characteristics and differences of two typical ultrasonic radar products, AK1 and AK2, to help readers better understand their application scenarios and advantages.

AK1 Ultrasonic Radar Overview 

AK1 ultrasonic radar is an earlier generation product on the market and is mainly used for short-range detection, such as automatic parking assist systems (APA). With its stable performance and high cost-effectiveness, AK1 radar has been widely used in the automotive industry.

Features:

Short-range detection: suitable for short-range obstacle detection within a few meters.

Cost-effectiveness: Compared with other sensors, AK1 radar has a higher cost-effectiveness.

Wide application: suitable for a variety of car models and automatic parking systems.

AK2 Ultrasonic Radar Overview

AK2 ultrasonic radar is the product of technological progress. It not only inherits the advantages of AK1, but also significantly improves its functions and performance. AK2 radar supports more complex scenarios and more advanced autonomous driving functions.

Features:

Range and short-range detection: AK2 radar can cover the detection range from short distance to longer distance, adapting to more application scenarios.

Resolution: provides more accurate obstacle identification and positioning.

Intelligent fusion: it can integrate data with other sensors such as cameras and millimeter-wave radars to provide more comprehensive environmental perception.

Suitable for advanced autonomous driving: meets the requirements of L3 and L4 autonomous driving systems.

Differences in application scenarios

AK1: Mainly used in automatic parking assistance systems to provide detection of obstacles around the vehicle.

AK2: Suitable for more advanced autonomous driving functions, such as automatic lane change, automatic parking and valet parking.

Market positioning and development trends

AK1 ultrasonic radar is still the first choice for many economical vehicles and automatic parking systems due to its stable performance and cost-effectiveness. However, with the development of autonomous driving technology, AK2 ultrasonic radar is gradually becoming the new favorite of the market with its advanced functions and performance, especially in high-end models and applications in the field of autonomous driving.

The leading company in AK2 ultrasonic radar in Southeast Asia 

In Southeast Asia , although AK2 ultrasonic radar technology is in its early stages of development , ADW has made significant progress and market recognition in this field. The AK2 ultrasonic radar products manufactured by ADW meet high-end application requirements such as high resolution, anti-interference, functional safety and waveform encoding.

With the advancement of autonomous driving technology and the growth of market demand, the AK2 ultrasonic radar products of these companies are expected to play a greater role in the future. After years of verification in the international market , the " ultrasonic radar + vision " solution has become the mainstream for realizing intelligent driving functions. This multi-source perception solution meets the safety requirements of the policy with a higher cost-effectiveness. Its visual part is mainly used for remote monitoring, and the ultrasonic radar can achieve high-precision detection at close range, compensating for the camera's monitoring blind spot of spatial distance, bringing drivers a better driving experience.
