2021 Leiling Active Braking Trigger Conditions?
4 Answers
Leiling's active braking trigger conditions require the ACC adaptive cruise control system to be activated. When the vehicle's computer detects a potential collision risk, it will actively apply the brakes. ACC Adaptive Cruise Control System: The ACC adaptive cruise control system refers to an intelligent automatic control system developed on the basis of existing cruise control technology. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects speed signals. When the distance to the vehicle ahead becomes too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to appropriately apply the brakes and reduce engine power output, ensuring the vehicle maintains a safe distance from the vehicle in front. Pre-Collision System: The vehicle is equipped with pre-collision systems both front and rear. Whether driving normally or reversing, the vehicle will brake to a stop. If an abnormal situation is detected ahead, the system will activate to actively apply the brakes and reduce the likelihood of accidents. The system's indicators are arranged front and rear with a gap in between, resembling a ruler-like marker below. The active braking function operates at speeds below 100 km/h. When an obstacle is detected ahead and the driver does not apply the brakes, the active braking function will engage.
As a new Corolla owner, I've been studying the automatic emergency braking system since purchasing this car in 2021. The activation mainly relies on front radar and camera scanning for targets like vehicles, pedestrians, or bicycles. When the system detects a potential collision due to close distance or speed difference, it triggers warnings: first with beeps prompting the driver to brake. If the driver doesn't react or the situation is critical, it automatically applies brakes to reduce speed or stop completely. I've experienced this several times in city traffic when following too closely - it really helped prevent minor accidents. Activation depends on speed and target type: more sensitive to pedestrians at low speeds, prioritizing vehicles at high speeds. I recommend regularly cleaning the windshield for clear camera vision, and manually deactivating it during heavy rain or fog when the system may underperform. Ultimately, this safety feature taught me not to over-rely on it - maintaining vigilance remains crucial.
I've driven multiple cars, and the 2021 Levin's automatic emergency braking is indeed a great assistant. The activation conditions are based on distance and speed difference: the system uses sensors to determine whether an object ahead poses a threat. When it detects a high risk of collision, such as when the car in front brakes suddenly while your speed remains unchanged, it sounds an audible alert; if the driver takes no action or the risk persists, it automatically applies the brakes. In my daily driving, it often activates during highway following or at traffic lights, saving me from trouble. However, the system has limitations: detection may weaken in heavy fog or at night, reducing activation accuracy. I make it a habit to check the sensitivity settings in the vehicle menu, having tried both lower and higher settings. Overall, it's reliable, but remember that manual driving is safer in severe weather. The owner's manual details the activation conditions—new drivers should familiarize themselves with it first.
I'm passionate about automotive electronic systems, and the active braking trigger mechanism of the 2021 Leiling is quite fascinating. The system relies on the fusion of front radar and monocular camera detection: it responds when the relative speed between the target and the vehicle is high and the time difference is below a threshold. The triggering process involves warning first followed by braking, with pedestrian recognition effective at speeds between 10-50 km/h, and a broader range for vehicle-to-vehicle scenarios. During my urban test drive, I noticed it effectively prevents rear-end collisions in traffic jams, but may miss small objects at high speeds. The triggering conditions are algorithmically calculated, and I've adjusted the dashboard settings to alter the warning distance. Sensor accuracy is affected by temperature, requiring calibration checks in both hot summers and cold winters. This technology is cutting-edge in enhancing safety and definitely worth further exploration.
