What does PCS mean on the car dashboard?

PCS on the car dashboard stands for Pre-Collision System, also known as Pre-Safe Protection System. It can automatically detect obstacles ahead and calculate the possibility of a collision. If the system determines a high probability of collision, it will sound an alarm to alert the driver. The working principle of the Pre-Collision System is as follows: 1. After starting the vehicle, PCS automatically activates, and the radar continuously detects obstacles ahead. When the system detects an obstacle within a safe distance and determines a possible collision, it will sound an audible alarm and tighten the front seat belts; 2. If the driver still does not respond after the warning, and the system determines that the collision is unavoidable, it will apply appropriate braking to minimize the impact of the collision.
While researching automotive electronic systems, I noticed that the PCS displayed on the dashboard actually stands for Pre-Collision System, which translates to a collision prevention system. This system uses radar or cameras to scan the road ahead. If it detects that the distance to the vehicle in front is too close or there's an obstacle, the system will first flash lights or sound a horn to alert you to slow down. If your reaction is slow, it can even automatically apply the brakes for you, reducing the risk of rear-end collisions. This is similar to other safety technologies like automatic brake assist but is more comprehensively integrated. I believe understanding it can enhance driving awareness, especially on highways where it can be life-saving. Additionally, the system may generate false alarms due to rain, fog, or dirty sensors, so it's important to regularly check and clean the sensors.
