What does emergency braking refer to?
1 Answers
Emergency braking refers to slamming on the brakes. During vehicle operation, when encountering emergency situations, the driver must correctly and promptly use the brake system to bring the vehicle to a stop within the shortest possible distance. Simply put, it's hard braking, but emergency braking isn't just about stomping the brake pedal to the floor. The correct emergency braking method is also crucial, and emergency braking cannot be used under all circumstances. Introduction to the principle of automatic emergency braking system: 1. In terms of working principle, it is a closed-loop cycle process of perception, calculation, and execution. From an automotive engineering perspective, it is a comprehensive electronic control system composed of various monitoring and control sensors inside the vehicle, coordinated with the system controller, supporting operating software, and algorithms. It typically uses millimeter-wave radar or optical sensors to monitor the distance to the vehicle ahead or obstacles in real-time, combined with information from multiple sensors of the vehicle's own powertrain, braking system, stability system, etc. 2. It utilizes safety distance model parameters to calculate the safe distance under current conditions in real-time and compares it with the distance measured by the monitoring millimeter-wave radar or optical sensors to determine the safety status. When the monitored actual distance is less than the safe distance, even if the driver does not take manual braking measures, the system will actively send hydraulic pressure commands to the vehicle's electronic stability system under the premise of ensuring no tire slip occurs. Through coordinated work among various vehicle systems, the vehicle will instantly cut off or reduce power while simultaneously activating the braking system to avoid collision accidents.
