How to Perform Emergency Braking in a Vehicle Equipped with ABS?
1 Answers
Vehicles equipped with an ABS system can apply strong pressure to the brake pedal for braking. Below are the principles and methods for performing emergency braking in a car with ABS: 1. The ABS system allows the wheels to maintain a slight slip state during braking, preventing the tires from locking up. This effectively avoids side skidding caused by locked tires and enables the driver to maintain control over the vehicle's direction during emergency braking, ensuring safety. 2. During braking, the ABS system quickly detects the locking state of each wheel based on speed signals from the wheel speed sensors. It then closes the normally open input solenoid valve for the wheel that begins to lock, keeping the braking force constant. If the wheel continues to lock, the system opens the normally closed output solenoid valve, causing the braking pressure on that wheel to drop rapidly as the brake fluid is diverted to the reservoir. This prevents the wheel from completely locking up due to excessive braking force.
