What is PCS (Pre-Collision System)?

Security system pre-collision uses a radar sensor to detect obstacles in front of the vehicle and determine, in advance, if you can avoid the impact.

A front-mounted millimeter-wave radar sensor on the available Pre-Collision System (PCS) constantly monitors the distance and closing speed of a vehicle ahead. When the system's computer determines that a frontal collision is unavoidable, the PCS preemptively tightens the front seatbelts and preps the Brake Assist for increased braking pressure the moment the driver stops on the brake pedal.

The Pre-Collision System has a three-pronged operation:

First: The system identifies unavoidable obstacles just prior to collision.

Second: The system immediately activates a seatbelt ECU, which automatically tightens driver and passenger seatbelts.

Third: At nearly the same time, the system automatically activates a pre-collision brake system to reduce vehicle speed.

When a radar sensor -- mounted to the front of the car -- detects that a frontal collision is unavoidable, the PCS springs into action by tightening the front seat belts. It also preps the car's Brake Assist System, a system designed to ensure the vehicle's anti-lock brakes engage. If the system determines that it is, activated form of preventive pre-safety belt pre-collision of the front seats and simultaneously prepare the assistant emergency braking to obtain optimum effectiveness once they stepped on the brake pedal.
