AK2 Car-mounted Ultrasonic Sensor: Empowering Integrated Advanced Iteration of Automated Parking and Driving

Recently, China issued a notice on conducting pilot projects for the access and on-road operation of intelligent connected vehicles (ICVs), specifying requirements for the admission of advanced autonomous driving and enhancing related regulations.

Accompanying the notice is the "Implementation Guide for Pilot Implementation of Access and On-road Operation of Intelligent Connected Vehicles (trial)", which emphasizes the necessity for high-level autonomous driving to possess excellent safety performance, including driving and parking safety. This article elaborates on the technical advantages of the AK2 car-mounted ultrasonic sensor, a rising star in distance measurement sensors, in terms of parking safety and improving parking efficiency.

Outstanding Distance Measurement Performance Ensuring Parking Safety

Longer range measurement

In the current context where automotive companies are showcasing their new energy MPV models, indicating a new round of competition in the C and D segment passenger car markets, the AK2 car-mounted ultrasonic sensor, with a measurement range of up to 7 meters, offers superior distance measurement and obstacle avoidance capabilities compared to similar products. This provides excellent hardware support for intelligent driving systems across various vehicle models.

Smaller blind spots

The AK2 car-mounted ultrasonic sensor has blind spots as small as 15cm, enabling more precise detection of nearby obstacles, thus better identification and planning of smaller and narrower parking spaces. Moreover, the product boasts a measurement accuracy of ±2cm and a resolution of 1cm, far exceeding that of similar products.

Balancing Frequency Coding and Refresh Efficiency to Improve Parking Efficiency

Programmable Frequency Coding for Switching between Long and Short Range Measurement

With a bandwidth of 8K, the AK2 car-mounted ultrasonic sensor supports frequency modulation, allowing the ultrasonic signal to be free from fixed frequencies, significantly improving the recognition rate of perception signals and avoiding interference from signals of the same frequency. Additionally, the product enables switching between long and short-range measurement.

Short Refresh Duration Enabling Synchronous Operation of Multiple Sensors

The product ensures quick single-detection refresh, with a refresh duration of<40ms, and can accommodate the synchronous operation of up to 6 sensors. It features various coding and fixed frequency settings, allowing the system to control sensor operating modes based on functionality.

High-Quality Production Ensuring Safety and Reliability

Product Complies with ASIL-B Functional Safety Level

It's worth mentioning that ADW has always prioritized product safety and reliability. Following the globally recognized automotive functional safety standard ISO 26262-2018 requirements, the product meets the functional safety ASIL-B level requirements, complying with the functional safety development requirements of world-class OEMs and Tier1 suppliers.

ADW has established an "ASIL D" level product development process system.

In response to the notice's qualification requirements for upstream component suppliers of intelligent connected vehicles in order to provide better products and services, in February of this year, ADW established a product development process system in line with the highest functional safety level "ASIL D" requirements and was awarded the ISO 26262:2018 ASIL D automotive functional safety process certification, ensuring the safety of the intelligent automotive industry.

As the first batch of enterprises in China to realize the mass production of AK2 ultrasonic sensors, ADWL's products belong to the advanced level in the industry, and there is no significant and essential difference with the international leading sensors from the comparison of product parameters. At present, ADW's AK2 ultrasonic sensors have been applied in the new models of many Tier1 and automotive companies, and the standard installation of AK2 ultrasonic sensors in the traveling and parking solution is expected to break through 20 new models in 2024.

As one of the first domestic enterprises to achieve mass production and application of AK2 car-mounted ultrasonic sensors, ADW products are at an advanced level in the industry, with no significant or essential differences from internationally leading sensors in terms of product parameters. Currently, the company's AK2 car-mounted ultrasonic sensors have been applied in new models of several Tier1 suppliers and automotive companies, with expectations of over 20 new models equipped with AK2 car-mounted ultrasonic sensors in 2024 as part of integrated parking and driving solutions.

ADW: Leading Enterprise in AK2 Car-mounted Ultrasonic Sensors

As early as 2006, ADW has passed the IATF16949 system certification and entered the front-loading supply chain of car manufacturers, gradually promoting the import substitution of car-mounted ultrasonic sensors and becoming a mainstream supplier of domestic car-mounted ultrasonic sensors, serving car manufacturers and their Tier1 suppliers for over twenty years, with a high industry status and market share in segmented markets.

With the implementation of policies and the rise of integrated parking and driving, ADW's AK2 car-mounted ultrasonic sensors provide more reliable safety support for the parking systems of smart connected vehicles with its outstanding performance and wide range of applications, injecting a new perceptual power into the development of the automotive industry.
