→ Sensors can be used to prevent collisions through the detection of objects in the path or vicinity of the vehicle.

→ GPS shows the vehicle’s position on the Earth’s surface using triangulation.

Successful answers should describe the basic principle and one of the following:

Basic principle:

→ Control technologies involve a signal input from the car/driver to a processor which provides an output or action to be taken.
 

Technology examples:

→ Cameras monitoring the position of a car in the lane. If the car exits the lane, the processor detects this and outputs an alarm to the driver.

→ Semi-autonomous driving. The car can activate brakes without driver intervention if a collision/obstacle is detected.

→ Cruise control. A speed is given as an input and a fuel rate is given to the engine to maintain this speed.

→ PID control. Like cruise control, this uses input from LIDAR sensors and cameras to detect obstacles and other cars, and to slow down if necessary.
