Tractor technology locks into new braking system

摘要

Stomp hard on the brake pedal of most modem cars, vans and trucks (make sure there is no one behind before trying this) and a rapid juddering confirms that the anti-lock braking (ABS) system is working as it should. In essence, ABS functions by sensing the rotation speed of each wheel, registering rapid deceleration, and automatically releasing brake pressure momentarily to prevent any of the wheels locking up while the vehicle is still in motion.
