Lecture Notes: Advanced Driver Assistance Systems (ADAS) and Automatic Emergency Braking (AEB)

Introduction

• ADAS Overview: Advanced Driver Assistance Systems (ADAS) are becoming increasingly popular in modern vehicles.
• Focus on AEB: Automatic Emergency Braking (AEB) is a critical ADAS feature, characterized by its ability to apply brakes without driver intervention when a collision is imminent.
• Importance of Testing AEB: Given the chaotic driving conditions, it’s important to understand how effective AEB systems are.

Vehicles Tested

• 2023 Honda City: India’s most affordable ADAS-equipped car.
• Mahindra XUV700
• Hyundai Ioniq 5 EV
• Mercedes AMG EQS 53: High-end, expensive model over two and a half crore.

Test Conditions

• Speed: All cars were tested at 40 km/h.
• Location: Closed section of the road, ensuring safety and controlled conditions.
• Safety Measures: Use of a crash test dummy to simulate real-world scenarios.

Individual Vehicle Performance and Observations

2023 Honda City

• Braking Performance: Detected the pedestrian and braked early and consistently.
• Driver Confidence: Increased trust in the system with repeated attempts.
• Issues: Manual transmission required restarting the car after each brake.

Mahindra XUV700

• Braking Performance: Detected pedestrian but braked late, requiring manual intervention.
• Consistency: Inconsistent performance – sometimes braking late, leading to decreased driver trust.
• Driver Confidence: Lower due to inconsistent braking behavior.

Hyundai Ioniq 5 EV

• Braking Performance: Initially braked late but improved with subsequent tests.
• Driver Confidence: High due to progressive and reassuring braking.
• Consistency: Consistent after initial test, creating a comfortable and confident experience.

Mercedes AMG EQS 53

• Braking Performance: Braked very close to the obstacle, slamming the brakes towards the end.
• Driver Confidence: Increased after understanding the system’s behavior but still felt unnatural.
• Issues: Felt unnatural due to the timing of the braking.

Summary and Insights

• Mercedes AMG EQS 53: Confident with powerful brakes but unnatural due to late braking.
• Hyundai Ioniq 5 EV: Most comfortable and progressive braking, creating a high-confidence experience.
• Mahindra XUV700: Inconsistent, leading to lower trust in AEB.
• 2023 Honda City: Most consistent and trustworthy, despite being the most affordable.
• Context: These tests are controlled; real-world performance may vary.

Conclusion

• AEB Systems: Effective but trust varies by vehicle. Potential issues due to sudden braking.
• Real-World Application: In dense traffic, AEB can be counterproductive due to close driving habits.
