Sensors for automobiles

1 Radar Radar

High-end cars have been loaded with radar, which can be used to track nearby objects. For example, the Mercedes automatic Cruise control system is an accident prevention system with a device on the rear bumper that alerts when an object is detected in a blind spot in the car.

2 Lane Keeping System lane-keeping

Cameras mounted on the windshield can identify lane markings by analyzing differences in road and boundary lines. If the car accidentally leaves the driveway, the steering wheel will vibrate slightly to alert the driver.

3 Laser Ranging system lidar

Google adopted the Velodyne company's roof laser ranging system.

4 IR Camera Infrared Camera

Mercedes ' night vision AIDS uses two headlights to send invisible and non-reflective infrared light to the road ahead. The cameras mounted on the windshield are used to detect infrared markings, and the illuminated image is presented on the dashboard display (where the risk factors are highlighted).

5 Stereoscopic Vision Stereo Vision

Mercedes's prototype system loaded two cameras on the windshield to generate a three-dimensional image of the road ahead in real time, detecting potential hazards such as pedestrians and predicting their actions.

6 gps/Inertial Navigation system

Radar Sensors

An automatic driver needs to know where he is going. Google uses the Applanix company's positioning system, as well as their own mapping and GPS technology.

7 Wheel Angle Encoder Wheel Encoder

The wheel-mounted sensor can measure the speed of a Google car as it travels through the traffic.
