The recent sensational Chinese car millet car strong release, SU7 with superior parking technology and a series of intelligent applications favoured by users, instant access to a high volume of large fixed. It can be seen that, with the continuous advancement of automotive intelligence, "line parking" and other high-level parking technology has gradually become a hot spot in the market. Ultrasonic sensors as the core component of intelligent parking system, its market demand is ushering in a period of rapid growth. In this paper, we will discuss the two major driving factors of this phenomenon and introduce the performance advantages of the new generation of AK2 Ultrasonic Sensor independently developed by AUDIOWELL.
Two major factors
1. Development of intelligent parking system
In recent years, with the accelerated development of vehicle intelligence, the function of parking system has been expanding, such as close-range remote parking (RPA), cross-floor memory parking (HVP) and long-distance unmanned valet parking (AVP) and other technologies have gradually become mainstream. According to statistics from Zuosi Information Consulting, the assembly rate of APA fusion parking systems for passenger cars in China will reach 8.2% in 2023, up 3.0 percentage points year-on-year, while the assembly rate of higher-order parking will be 0.7%, up 0.4 percentage points year-on-year. This indicates that low-speed APA parking, especially APA fusion parking, and high-order parking, especially memory parking, will usher in a period of rapid growth.
2. System integration under the domain controller architecture
Under the domain controller architecture, the driving and parking systems are beginning to converge, i.e. driving and parking as one. The biggest feature of this fusion is that driving and parking can deeply reuse and share sensors and arithmetic resources. 2023, the driving and parking technology will enter the scale landing stage, promoting the high-speed development of the automated parking market, and ultrasonic sensors, as the core sensing components, will also usher in the development of the "fast lane". According to Zuosi Information Consulting statistics, in 2023, China's passenger car parking assembly volume reached 1.602 million units, an increase of 61.4% year-on-year; the assembly rate reached 7.6%, an increase of 2.6 percentage points year-on-year. It is expected that by 2025, the assembly volume of rows of parking one will exceed 3 million vehicles, the assembly rate of more than 15%; by 2028, the assembly rate will reach about 25%. It can be seen that the future of "line parking one" is promising.
Advantages of the new generation of AK2 ultrasonic sensors
In order to meet the upgrading of the parking system and the promotion and application of the line parking technology, the market has put forward higher requirements for the performance of ultrasonic radar. In order to cope with the upgrading of technical demand, AUDIOWELL independently developed a new generation of AK2 ultrasonic sensors, the product has the following significant advantages through technological innovation:
Longer detection distance:
The detection distance of AK2 ultrasonic sensor can reach 7m, which provides more excellent distance measuring technology hardware support for intelligent driving system.
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.
Be capable of frequency modulation, to achieve far and near range switching:
AK2 ultrasonic sensors have 8K bandwidth, support frequency modulation, so that ultrasonic signals are not limited to a fixed frequency, significantly improve the recognition rate of the perceived signal, to avoid interference with the same frequency. At the same time, the product can be achieved near and far range switching.
Refresh time<40ms, support multiple mode 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 sensor work mode.
With self-diagnostic function:
The 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 "in the warehouse", "out of the warehouse".
Meet Functional Safety ASIL B Requirements:
The product meets the requirements of Functional Safety ASIL-B level in accordance with the globally recognized automotive functional safety standard ISO 26262-2018, which meets the functional safety development requirements of the world's leading OEMs and Tier1s.
AUDIOWELL: First Tier Company of AK2 Ultrasonic Sensors
As a mainstream supplier of automotive ultrasonic sensors in China, AUDIOWELL has more than 20 years of experience in providing services to vehicle manufacturers and their Tier-1 suppliers. The company is in a leading position in the industry, and is one of the first companies to realize the mass production application of AK2 ultrasonic sensors, and its products have long been delivered in batch and marketed for sale.At present, AUDIOWELL's AK2 in-vehicle ultrasonic sensors have been widely used in the models of both Chinese and foreign joint venture and Chinese branded car manufacturers, and it is expected that the installation volume of the in-vehicle parking solution will exceed 20 new models within this year.
As early as in 2006,AUDIOWELL passed the IATF16949 quality system certification, and gradually promoted the import substitution of vehicle-mounted ultrasonic sensors. The quality of the products produced by the company has reached the advanced level in the industry, and there is no significant and essential difference in parameters with the leading international sensor products, so the company occupies a high position in the industry and has a significant market share in the market segments.
In February 2023,AUDIOWELL was awarded the ISO 26262:2018 ASIL D Automotive Functional Safety Process Certification, marking that the company has become one of the few automotive ultrasonic sensors suppliers in the industry to have established a product development process system that complies with the highest level of functional safety, ASIL D. This certification not only proves the high standard of safety performance, but also provides a solid guarantee for the safety development of the smart car industry. This certification not only proves the high standard of AUDIOWELL's product development process in terms of safety performance, but also provides a solid guarantee for the safe development of the smart car industry. In the future, AUDIOWELL will continue to contribute to the safety and progress of the smart car industry.
