How to Perform Emergency Braking with ABS?
2 Answers
To perform emergency braking with ABS, you should firmly and forcefully press the brake pedal. ABS, short for Anti-lock Braking System, functions by automatically controlling the braking force during vehicle braking to prevent wheel lock-up, keeping the wheels in a state of rolling and sliding to ensure maximum traction between the tires and the road. The working principle of ABS is: 1. Based on the speed signals from the wheel speed sensors, it determines if a wheel is about to lock up and closes the input solenoid valve for that wheel to maintain constant braking force; 2. If the wheel continues to lock up, it opens the output solenoid valve, allowing the braking pressure on the wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the braking force from completely locking the wheel.
That day on the highway, a car suddenly braked hard in front of me. My car has ABS, so I stomped the brake pedal all the way down and felt it vibrating, but I kept my foot firmly pressed. The ABS automatically controlled the braking frequency to prevent wheel lock-up, allowing me to steer slightly to avoid the obstacle ahead. The key is to press the brake pedal hard and hold it—don’t pump or release it—while keeping the steering wheel steady. This system is designed for emergencies, so it’s good to practice in a safe area a few times to get familiar with the pedal feel. In a panic stop, stay calm—bringing the car to a controlled stop is what matters most.
