Haval Big Dog has automatic emergency braking. Introduction to Automatic Emergency Braking System: The automatic emergency braking system is a system that can help drivers shorten braking distance before taking action. The Haval Big Dog is equipped with this system. When approaching an obstacle too closely, the system will automatically apply emergency braking without requiring driver intervention. Composition of Automatic Emergency Braking System: Like other driver assistance systems, the AEB system consists of three main components: perception, decision-making, and execution. Specifically (mainstream solution), radar and cameras serve as sensors to form the perception part. The sensors have built-in ECU or independent external ECU to complete decision-making, and send braking requests via bus to the actuator - usually ESP, or other devices such as brake-by-wire systems (e.g. Bosch's iBooster) or independent high-pressure accumulator controllers - to brake the vehicle.

The Haval Big Dog is indeed equipped with an active braking system, which is available in most high-end versions of the 2023 model at least. I remember test-driving it before, and the system was quite responsive—it automatically triggers braking when the vehicle approaches an obstacle ahead, helping to avoid collisions. This feature is called AEB (Autonomous Emergency Braking), but in daily driving, I prefer to simplify it by saying it's like having an invisible co-pilot constantly protecting you. Especially in urban traffic jams, it can reduce the risk of rear-end collisions. As part of the safety features, Haval has integrated it into the intelligent driving system, and owners only need to check whether the active safety options are enabled in the vehicle settings. However, it's important to note that if you purchase an older or lower-trim version, this feature might not be included, so always review the configuration list when choosing a car. Overall, I think this car performs reliably in terms of active braking, enhancing driving safety and preventing major issues caused by minor oversights.

As an owner of the Haval Big Dog, I've driven it for over a year and can confidently say it has autonomous emergency braking. This feature activates automatically every time I start the vehicle. I've tested it several times on highways and intercity roads, and it effectively avoided suddenly stopped cars ahead. From my experience, it doesn't constantly interfere with driving—it only activates in critical situations, such as when the distance becomes too close and the driver doesn't react, automatically slowing the car down. I've personally benefited from this feature: it reduces misjudgments, especially providing an extra layer of safety when I'm fatigued or distracted. However, keep in mind that not all versions are the same—my mid-range trim has it, but the base model might lack this feature. I recommend potential buyers pay extra attention to safety features during test drives and ask sales staff for details.

From a safety perspective, the autonomous emergency braking system in Haval Big Dog is highly effective in reducing accidents, especially for novice drivers or daily commuters. I understand that in modern vehicle design, such systems utilize radar sensors to detect potential frontal collisions and intervene with braking when necessary. Specifically for the Haval Big Dog, it has performed well in crash tests, demonstrating effectiveness in preventing low-speed rear-end collisions. However, it's important to note the operating conditions: the system may have limitations during rainy or foggy weather, and owners should keep the camera lens clean. Whether this feature comes as standard or an optional extra depends on the model year and trim level. Overall, it's an essential driving aid that significantly enhances peace of mind for both drivers and passengers.
