Custom-Developed Pre-Installed Blind Spot Detection (BSD) System

We successfully delivered a Blind Spot Detection (BSD) system to an international automotive client. This highly integrated pre-installed millimeter-wave radar safety solution integrates blind spot detection, lane change assist, door opening warning, and rear-side collision warning, and is deeply customized to meet the pre-installed needs of modern commercial vehicles and passenger cars for enhanced active safety. The success of this project demonstrates our comprehensive capabilities in the field of automotive active safety electronics, from forward-looking design and sophisticated algorithms to automotive-grade manufacturing.

Client Requirements: The system needs to operate stably in all scenarios, including highways, urban areas, and stationary environments, effectively identifying various targets such as vehicles, motorcycles, bicycles, and pedestrians, while minimizing false alarms.

• Functional Integration and Intelligence: The system needs to integrate multiple warning logics (such as tiered warnings and Time-of-Collision (TTC) algorithms) and intelligently link with vehicle turn signals and gear shift signals to provide intuitive and effective warnings. • Stringent Automotive Standards: Must meet OEM automotive-grade requirements such as wide operating temperature range of -40°C to 85°C, IP67 protection rating, electromagnetic interference resistance, and long-term vibration reliability.

• Convenient Integration and Installation: Provides complete system solutions (radar, indicator lights, wiring harnesses), with clearly defined installation procedures to facilitate efficient assembly and calibration by OEMs on the production line.

Our Solutions and Product Features: Our system is a complete hardware and software integrated solution with the following core advantages:

1. Full-Scenario Intelligent Warning Logic: Dual-mode adaptive, four-level warning system, high-precision filtering algorithm

2. Advanced Hardware and Performance:

24GHz Millimeter-Wave Radar Platform: Employs a one-transmitter-two-receiver or multi-channel design, achieving a horizontal detection angle of ±35° for accurate measurement of target distance, speed, and angle.

Excellent Environmental Adaptability: Wide operating temperature range, IP67 protection rating, ensuring reliability in harsh weather and complex road conditions.

3. Simple System Integration: The system does not rely on an OBD interface; it operates by directly connecting to the ACC power supply, turn signal, and reversing light signals, offering high integration and strong adaptability.

4. Comprehensive OEM Support: Provides detailed installation specifications, including precise installation positions and angle requirements (35° tilt angle) for the radar on the front and rear bumpers, as well as recommended installation positions for indicator lights and buzzers in the driver's cabin.

5. Complete Wiring Harness and Connection Solutions: Equipped with dedicated wiring harnesses and clearly defined wiring definitions and precautions to ensure safe and stable electrical connections.

6. System Self-Test and Functional Testing Procedures: Provides clear standard operating procedures for final inspection on the production line and after-sales maintenance.

Service Process Overview:

• Technical Collaboration and Requirements Freeze-up: In-depth discussions with the client's engineering team regarding functional definitions, performance indicators, and system interface protocols to create a customized product specification.

• System Design and Development: Completion of radar RF, antenna, and structural design, as well as development of core warning algorithms and logic software. Multiple rounds of simulation and bench testing are conducted. • Vehicle Matching and Verification: On-vehicle testing is conducted on the target vehicle model to complete radar calibration, functional verification, and environmental durability testing, optimizing the installation process.

• Production and Delivery: After approval, mass production is carried out under a quality system compliant with IATF 16949 standards to ensure product consistency and timely delivery to the customer's assembly line.

Application Scenarios and Value: This system can significantly improve driving safety in the following scenarios:

• Highway and Expressway Driving: Effectively monitors vehicles rapidly approaching from the side and rear, providing lane change assist warnings in case of driver inattention to avoid collisions.

• Urban Congested Traffic: Accurately identifies small targets such as motorcycles and electric vehicles during frequent lane changes or low-speed crawling in traffic, reducing the risk of scrapes.

• Door Opening While Parking: Automatically activates door opening warning after the vehicle comes to a complete stop, preventing "door opening kill" accidents and protecting the safety of passengers and other road users.

• Reversing Out of Parking: Provides side and rear lateral collision warnings while reversing, compensating for the insufficient field of vision of traditional reversing cameras.

This case demonstrates our commitment as a reliable Tier 1 automotive electronics supplier to helping global automotive brands create safer and smarter mobility experiences through innovative technology and reliable quality.
