What are the triggering conditions for the Leiling's automatic emergency braking?
2 Answers
Leiling's automatic emergency braking is triggered when the ACC adaptive cruise control system is activated, and the vehicle's computer detects a potential collision risk. ACC Adaptive Cruise Control System: The ACC adaptive cruise control system is an intelligent automatic control system developed based on 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 coordinates with the anti-lock braking system and engine control system to apply appropriate braking and reduce engine power output, ensuring the vehicle maintains a safe distance from the vehicle ahead. Pre-Collision System: The vehicle is equipped with pre-collision systems both front and rear, which will apply braking during normal driving or reversing if necessary. If an abnormal situation is detected ahead, the system will activate automatic braking to prevent accidents. The system's indicator consists of two vehicle symbols arranged front and back with a gap in between, and a scale-like mark below. The automatic braking function operates at speeds below 100 km/h. If an obstacle is detected ahead and the driver does not apply the brakes, the automatic braking function will activate.
I've been driving the Levin for almost three years now, and the pre-collision system has activated several times during my urban commutes. Its millimeter-wave radar and camera are constantly monitoring the road, calculating collision time whenever sudden deceleration from pedestrians or vehicles ahead is detected. If the system determines I can't react in time or haven't applied the brakes, it will intervene to stop the car. From my observation, it triggers most frequently when speed exceeds 30 km/h. Once during rain when mud obscured the camera, the system prompted me to clean the sensors, demonstrating how external conditions can affect sensitivity. The most impressive aspect of Toyota's PCS is its ability to detect electric bike riders - in real-world tests, it reliably stops the car even at 50 km/h. However, I'd recommend not relying solely on the computer; staying prepared to brake manually is always wiser.
