Under what conditions does Toyota's automatic braking system activate?

When the vehicle speed reaches 30km/h, this system will automatically activate; When the preceding vehicle brakes, stops, or encounters other obstacles, it will automatically apply additional force to the braking system to help the driver reduce braking distance before taking action
I've studied this before while driving. The activation of Toyota's Pre-Collision System depends on several conditions. First, the speed range is crucial—it's most likely to trigger between 10 to 80 km/h, as it may be less responsive at higher or lower speeds. If the radar or camera detects a sudden deceleration or stop from the vehicle ahead and you haven't applied the brakes, the system may automatically intervene. It's also highly sensitive to pedestrians crossing the road, especially those darting out suddenly from the roadside. Be cautious during rainy or foggy conditions, as the system's detection capability might be reduced. I've noticed that if you're following too closely without lifting your foot off the accelerator, the dashboard will first flash a red warning light. If there's still no reaction, the system will apply the brakes directly. This feature is particularly useful in city traffic jams, helping to prevent many minor rear-end collisions.
Once when I was driving, the car in front suddenly braked hard, and the automatic emergency braking system kicked in, which gave me a scare. This system mainly activates when it detects a collision risk, such as when the distance to the car ahead is rapidly decreasing but you're still pressing the accelerator. It works through a combination of the camera on the windshield and the radar in the car emblem, capable of recognizing vehicles and pedestrians during the day, though its ability to detect bicycles weakens at night. The activation happens in two steps: first, it emits a beeping sound and a dashboard warning, and if there's no response within half a second, it automatically applies the brakes. However, sensitivity decreases during turns or on steep slopes, and it may fail in heavy rain. It's recommended to keep the sensors clean and avoid placing stickers on the car emblem that could block radar signals. Remember, automatic emergency braking isn't foolproof—don't rely on it when you should be braking yourself.
