Google Driverless Car- The Obstacle Detection Unit

  1. That’s damn neat! It reminds me of the James bond movie – Tomorrow never dies, the car which drives by itself with voice recognition. Slowly I guess we are getting there now 🙂

    1. Hi Vinay,

      Yes you are right. Ten year back whatever was fiction is going to be a reality in next 5 to 10 years.
      This car is awesome, we have just introduced our readers to the driverless car with these four posts. String of posts on GDLC will be coming.

      Stay Tuned , 😉 keep reading….

  2. I have a question that’s not been answered yet. How does the obstacle detection unit differentiate between leaves or paper (or snow or rain) blowing across the road and more substantial obstacles, such as small critters, children, a cart, etc.?

    1. Hi Tanman,

      Great question mate. I really appreciate that you have given me a chance to answer that intriguing question.

      The autonomous driving computer is capable of determining the weather condition of road by using the obstacle detection unit.

      The computer collects the laser data of road while driving. The car computer has already stored the laser data of road for dry weather condition. It compares that collected data with the previously stored data for dry weather condition to check the road weather condition to know that whether it is raining or snow fall is happening.

      Apart from this it also compares the intensities of laser data collected by it. For example, If the value of intensity will shift toward darker side it signifies that rain is falling and because of that the road has became wet and darker.The computer also identifies rainfall by detecting whether water is being kicked up by a vehicle’s tires. It also identifies the rainfall by detecting puddles and wet tire tracks left by another vehicles.

      Similarly, if the intensity value shifts toward the brighter end that signifies that the road is covered with snow and because of that it becomes brighter than in normal conditions.

      It can also detect pedestrian, kids and bi-cycle on road. For this it compares there sizes, their behavior on road and the part of the road on which they are traveling, their speed and the like.

      I will suggest you to read this post –

      The car stores various kind of data in its memory. The data also contains the size info and behavior of such objects on road and based on them it makes control strategies.

  3. Laser has 360 degree horizontal view, so does GCar yield to faster traffic from the rear? Any plans Geep an off-road version of GCar? What kind of porting challenges did GCar face for having to build it on an Electric platform from ICE cars.
    I really love the idea of driverless cars from Minority report and iRobot. Its great that Google is working on this with great amount of seriousness.

    1. Google is working on an autonomous car computer. Google is using group of 10 cars for the test. These are
      * 6 Toyota Prius
      * 1 Audi TT
      *3 Lexus RX450

      Thus, Google is not manufacturing car but developing a computer only and this computer can work with any kind of car. I think they are not going to face too much porting challenges.

  4. I can’t help but wonder if any of the sensing technology is at risk of interfering with other driver-less vehicles, or with common ways police determine vehicle speed. Namely, will the laser array cause problems with laser speed guns, or the radar system confuse radar guns or set off radar detectors in other drivers cars? Anyone do any tests to make sure the sonar doesn’t bother bats?

    1. No they are not going to interfere with other driverless vehicle. However, they are going to communicate with each other and they will be passing information to each other for better and safe driving on road. This is called vehicle to vehicle communication.

      I think measures will be there to protect these living species. Bats use to fly in air and Sonar has horizontal field of view. It will not be scanning a larger area above the car roof. 🙂

  5. Very informative post on Google Driverless cars. All along I thought that Google was manufacturing these cars, but after reading this & comments I realize that Google is using Toyota , Audi & Lexus to come up with driverless models. Thanks for sharing,
