Forward Collision Warning (FCW)

A system that alerts the driver to a potential collision with a vehicle ahead.

Collision Avoidance

Technologies designed to prevent collisions from occurring in the first place.

Sensor Fusion

The process of combining data from multiple sensors to create a more accurate understanding of the vehicle's surroundings.

ADAS (Advanced Driver-Assistance Systems)

Electronic technologies that assist drivers in driving and parking functions.

Impact Absorption

The ability of a vehicle's structure to absorb energy during a collision, reducing the forces on occupants.

Why It Matters

Crash mitigation features are important when buying a car. They can significantly reduce the risk of accidents and injuries. Look for cars with advanced crash mitigation systems to enhance your safety on the road.

Listen

Crash mitigation refers to the technologies and strategies employed in vehicles to minimize the severity of a collision and its consequences.

It encompasses a wide range of features, from basic seatbelts and airbags to advanced driver-assistance systems like automatic emergency braking and lane departure warning.

The goal is to reduce the likelihood of a crash occurring in the first place, and if a crash is unavoidable, to lessen the impact forces on the occupants.

Modern crash mitigation systems often use sensors, cameras, and radar to detect potential hazards and react accordingly.

These systems can automatically apply the brakes, tighten seatbelts, or adjust the vehicle's steering to avoid or reduce the severity of an accident.

Ultimately, crash mitigation technologies are designed to protect vehicle occupants and other road users, making driving safer for everyone.

क्रैश मिटिगेशन से तात्पर्य उन तकनीकों और रणनीतियों से है जो किसी टक्कर और उसके परिणामों की गंभीरता को कम करने के लिए वाहनों में नियोजित की जाती हैं।

इसमें बुनियादी सीटबेल्ट और एयरबैग से लेकर स्वचालित आपातकालीन ब्रेकिंग और लेन प्रस्थान चेतावनी जैसी उन्नत चालक-सहायता प्रणालियों तक सुविधाओं की एक विस्तृत श्रृंखला शामिल है।

इसका लक्ष्य सबसे पहले दुर्घटना होने की संभावना को कम करना है, और यदि कोई दुर्घटना अपरिहार्य है, तो सवारों पर प्रभाव बलों को कम करना है।

आधुनिक क्रैश मिटिगेशन सिस्टम अक्सर संभावित खतरों का पता लगाने और उसके अनुसार प्रतिक्रिया करने के लिए सेंसर, कैमरों और रडार का उपयोग करते हैं।

ये सिस्टम स्वचालित रूप से ब्रेक लगा सकते हैं, सीटबेल्ट को कस सकते हैं, या दुर्घटना से बचने या उसकी गंभीरता को कम करने के लिए वाहन की स्टीयरिंग को समायोजित कर सकते हैं।

अंततः, क्रैश मिटिगेशन प्रौद्योगिकियों को वाहन सवारों और अन्य सड़क उपयोगकर्ताओं की सुरक्षा के लिए डिज़ाइन किया गया है, जिससे सभी के लिए ड्राइविंग सुरक्षित हो सके।
