Sensor abilities
Sensors enable vehicles to
• Eliminate blind spots
• Stay in traffic lanes by watching lane markers
• Track vehicles ahead for active cruise control
• Park with little or no driver assistance
• Monitor traffic signs
• Provide 360-degree road surveillance to enable automatic lane changes
Fully autonomous cars may be a decade away, but the sensors they'll need for collision avoidance -- radar, cameras, ultrasound and lidar -- have become a big business already.
