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 ultrasonic sensor, a rising star in distance measurement sensors, in terms of parking safety and improving parking efficiency.
Excellent distance measurement performance for safe，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 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 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 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 AUDIOWELL 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.
AUDIOWELL 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, AUDIOWELL 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.
