What is Pre Collision System?

These systems use sensors to detect an imminent crash and automatically apply the brakes or take other corrective action. Pre-collision systems can be standalone features or part of a larger driver assist package.

What is Toyota Pre Collision System?

Pre-Collision System is an advanced safety system that uses sensors to monitor the environment in front of your vehicle. If a potential collision is detected, the system will alert the driver and provide additional braking force if necessary. The goal of the Pre-Collision System is to help reduce the severity of accidents by providing extra time for the driver to react.

The Pre-Collision System uses a camera and laser sensor to detect potential collisions. The camera can identify objects in front of the vehicle, while the laser sensor can measure the distance to those objects. Together, these sensors can provide a three-dimensional view of the area around your vehicle.

If a potential collision is detected, you will see a warning message on the multi-information display and an audible alarm will sound. If you do not take action to avoid the collision, Pre-Collision System will automatically apply brake pressure. The amount of brake pressure applied will depend on how close you are to the object and its speed relative to your vehicle’s speed.

In some cases, Pre-Collision System may also tighten your seatbelt as a precautionary measure. Pre-Collision System is designed to assist drivers in avoiding or reducing the severity of frontal collisions. It is not a substitute for safe driving practices and there are limitations to what it can do.

For example, Pre-Collision System may not activate or may fail to provide adequate braking pressure if: * You are driving too fast for conditions (e.g., poor weather or road conditions). * Your view of an object is obstructed (e.g., by another vehicle or object).

* An object you are approaching is very small (e.g., a bicyclist or motorcycle with low reflectivity). Toyota introduced Pre Collision System on select models in 2007, making it one of first automakers offer such technology [[1]]. As other carmakers have followed suit over years since then with similar systems dubbed by various names such as Automatic Emergency Braking (AEB), Front Collision Warning (FCW) ,and Crash Imminent Braking (CIB) [[2] ].
