Why is there a surge in demand for AK2 ultrasonic sensors in the automotive market?

2024-05-16 Product Information

This year, China's auto industry has shown unprecedented ‘bustle’, and the topics it has generated have sparked many concerns and hot debates on the Internet.

In China, from the price war at the beginning of the year to the release of new cars by major car companies, Chinese auto companies have taken the initiative to upgrade their performance and lower prices, while consumers' willingness to pay a high premium for brands has declined, demonstrating that automotive consumption has entered a new era in which price-performance is paramount.

Against this background, the development of automotive intelligence is moving towards high-end parking technology, such as ‘driving and parking in one’, and AK2 ultrasonic sensors have become an indispensable sensory core component of the intelligent parking system due to their excellent performance.

With the surge in market demand, AK2 ultrasonic sensors will usher in a golden period of development, opening up a new journey for intelligent parking technology.

AK2 Ultrasonic Sensors: Essential Hardware for Intelligent Sensing of ‘Driving and Parking in One’ in the Automotive Industry

With the accelerated development of Automotive, the function of the parking system continues to expand, such as Remote Parking Assist (RPA), Home Area Valet Parking (HAVP) and Automatic Valet Parking (AVP) and other technologies have gradually become mainstream.

On the other hand, under the domain controller architecture, driving and parking systems are beginning to converge, and ‘driving and parking in one’ is rapidly emerging and will enter the scale landing stage in 2023. Zuosi Information Consulting expects that in 2025, the assembly volume of the ‘driving and parking in one’  will exceed 3 million vehicles, with an assembly rate of more than 15%, and by 2028, the assembly rate of the ‘driving and parking in one’ will reach about 25%.

At the same time, ultrasonic sensor as the perception of intelligent parking system core components, and then ushered in high-speed development. Zuosi Information Consulting expects that the installed volume of ultrasonic sensor in domestic passenger cars will exceed 140 million in 2025, and in 2028, it will exceed 220 million. Among them, AK2 ultrasonic sensors have become the necessary sensing hardware for smart cars by virtue of their performance advantages.

Longer detection distance:
AK2 ultrasonic sensors have a detection distance of up to 7m, providing superior distance measurement technology hardware support for intelligent driving systems.

Smaller blind zone:
With a blind zone as small as 15cm, the AK2 ultrasonic sensor is able to sense close-range obstacles more accurately, with a measurement accuracy of up to ±2cm and a resolution of 1cm.

Codable frequency modulation,switch between long-range and short-range ranging:
AK2 ultrasonic sensors have 8K bandwidth, support frequency modulation, so that the ultrasonic signal is not limited to a fixed frequency, significantly improve the recognition rate of the perceived signal, to avoid the same frequency interference. At the same time, the product can be achieved near and far range switching.

Refresh time <40ms, support multi-modes switching:
The product guarantee bar single detection refresh fast, refresh time <40ms; the product can carry 6 sensors synchronous work, with a variety of coding settings, fixed-frequency setting conditions, the system can be based on the function of controlling the sensors work mode.

With self-diagnostic function:
T
he product has a self-test diagnostic function, can quickly detect the real-time signal transmission and reception, to ensure that in the narrow and cramped environment can also be achieved safely ‘Parking in the garage’, ‘Parking out of the garage’.

Meet Functional Safety ASIL-B Requirements:
The product meets the requirements of Functional Safety ASIL-B level in accordance with the globally recognised automotive functional safety standard ISO26262-2018, which meets the functional safety development requirements of the world's leading OEMs and Tier1s.

AUDIOWELL: the first company to mass produce AK2 ultrasonic sensors in China

AUDIOWELL has been working into the automotive ultrasonic sensors for more than 20 years, ranking among the mainstream suppliers in China, and serving major automotive manufacturers and their Tier-1 suppliers with its rich industry experience and technology accumulation.

As one of the first company to realize the mass production of AK2 ultrasonic sensors, AUDIOWELL's products have long been delivered in batch and sold on the market, and are widely used in the models of joint venture OEMs and domestic independent brand OEMs, and it is expected that the installation volume of AK2 ultrasonic sensors will break through to 20 new models within the year.

Since obtaining the IATF16949 quality system certification in 2006, AUDIOWELL has been promoting the import substitution of domestic sensor technology, and the quality of its products has reached the international advanced level, and there is no significant and essential difference in parameters between AUDIOWELL and the leading international sensor products, which ensures AUDIOWELL's leading position in the market and significant market share in the market segments.
