<p>avoidance requires the position of objects in its surroundings and the location of the vehicle relative to their positions.</p>

<p><big> Technology </big></p>
<p>Many collision avoidance systems need two things:</p>

<p>
* The position of all other vehicles<br/>
* The position of the vehicle relative to other vehiclesThe first step in collision avoidance is perception, which can use sensors like <a href="page.php?w=Lidar">LiDAR</a>, <a href="page.php?w=Camera">visual cameras</a>, <a href="page.php?w=Thermography">thermal or IR cameras</a>, or solid-state</p><p>
