The system alerts the driver to brake when it detects a probable collision, and if the driver does not act, the car stops by itself.

当即将撞到行人时，系统会对驾驶员提出警示，如果驾驶员没有采取行动，汽车也能自动停下来。

For example, collision preparation in an auto will affect the brake system, the safety system (which itself includes airbags, seatbelts, headrests, etc.), suspension, and more.

例如，一个汽车的防碰撞功能会影响到刹车系统、安全系统(又包括安全气袋、安全带、头靠，等等)、悬架，以及更多。

As the anticipated time-to-impact decreases, CMS prepares the car for sudden braking by moving the brake pads nearer to the brake disks, and finally, when the system concludes that a collision is less than one second away, it starts to apply the brakes itself.

The computer-control system can then apply the brake on the wheel concerned, and even adjust the amount of engine torque sent to that wheel, so that skidding is prevented.

Indeed, the prototype has a distance-keeping system that will brake to a standstill, and move off again when the car in front moves.
