  • BackgroundCar lanes next to youMust shoulder check, but really?Drivers must be reminded

  • Motivation410,000 lane-changing related accidents annually


    All of us can relate to the danger

    Vast number of cars

    Good drivers want to drive more safely


  • Existing ProductsBlind spot mirror2 mirrors to look at?

    Only on very recent modelsNot widely available

    Other similar products ~$500Too much


  • Our SolutionIncrease road safety


    Universal to personal cars

    Accurate (rain/snow, night/summer)

    Friendly toward all types of users

    Seen as a part of the car


  • *

  • Speed is over 30km/hTurn signal is on.BSDS checks for car in blind spot.Car found in blind spot, driver is warned.Collision is imminent.*

  • Current State of System


  • Product DesignSensors

    Processing circuit

    Warning system


  • SensorsWide angle (40 degrees)Should not detect past 3m (do not want to sense vehicles 2 lanes over)Should be fairly inexpensive

    Infrared , Laser, Photo Recognition, Sonar, Ultra SoundCostly, narrow angle, range issues


  • SensorsUltrasound Sensors meet our criteria (Wide angle +/- 20 degree, short range 2m, low cost)Parking Sensor purchased , sensor and driver used.Easily InstallableProven Field experience

  • SensorsSupposed to work up to 2.5mReliable results at 1.5m to 2.0mStill works for most vehicles in the parallel lane


  • Proposed Processing stage

  • Processing Circuitry

  • Warning SystemDiscreet and non-distracting

  • ON Time!*

  • Complete cycle of an engineering projectTime managementWorking with othersConstructive criticismProfessionalism

    *We Learned

  • Affordable productLarge target marketSimple to install & useClear & timely warningReduce accidents (cost & life)

    *Business Opportunity

  • Set goalsThorough planningTeam collaborationGood, better, bestBudget & time managementGoals achieved / useful product
