What is the difference between aeb and active braking?

Although automatic emergency braking (AEB) and active braking are both assisted driving technologies, the former only automatically brakes when an obstacle is detected, while the latter is more active and can predict collisions based on sensor and camera data. Interfere with driving operations. The advantage of AEB is to reduce the frequency of low-speed collisions; active braking expands the detection range of dangerous situations and more proactively prevents collisions. However, active braking is more expensive, may not predict a collision accurately, and may overly intervene in driving.

AEB and active braking: detailed explanation of the difference

Straight to the point answer:

Although AEB (autonomous emergency braking) and active braking are both assisted driving technologies, they are different in functions and trigger conditions.

Detailed answer:

Function:

• AEB: Automatic detection of the front obstacles and automatically brake to prevent or mitigate collisions.
• Active Braking: In addition to the functions of AEB, it can predict an impending collision based on data from sensors and cameras and actively intervene in driving operations such as steering or braking.

Trigger condition:

• AEB: Usually triggered after the obstacle ahead is detected by radar or laser sensor. When the vehicle speed is within a certain range and is close to an obstacle.
• Active braking: Not only relies on sensors, but also collects other information, such as vehicle speed, driving direction, steering angle, etc. Its trigger conditions are more complex and designed to identify potentially dangerous situations.

Advantages:

AEB:

• Reduces the frequency and severity of low-speed collisions.
• Reduce the driver’s reaction time.

Active braking:

• Expands the detection range of potentially dangerous situations.
• Intervene in driving more proactively to prevent collisions.
• Can be integrated with other assisted driving technologies (such as lane keeping assist) to provide more comprehensive protection.

Limitations:

AEB:

• May not be detected in some cases Obstacles such as oncoming vehicles or pedestrians.
• In adverse weather conditions, such as rain, snow, and fog, performance may degrade.

Active braking:

• The cost is higher.
• In some cases, predicted collisions may be inaccurate.
• May over-intervene in driving, causing the driver to lose control of the vehicle.
