Background Car lanes next to you Must shoulder check, but really? Drivers must be reminded

Motivation 410,000 lane-changing related accidents annually Costs All of us can relate to the danger Vast number of cars Good drivers want to drive more safely 6

Existing Products Blind spot mirror 2 mirrors to look at? Only on very recent models Not widely available Other similar products ~$500 Too much 7

Our Solution Increase road safety Economical Universal to personal cars Accurate (rain/snow, night/summer) Friendly toward all types of users Seen as a part of the car 8

Car Speed Turn Signal Processing Circuit Output Power ON Sensors Warning System 9

Speed is over 30km/h Turn signal is on. BSDS checks for car in blind spot. Car found in blind spot, driver is warned. Collision is imminent. Car found in blind spot, driver is warned. Collision is imminent. 10

Current State of System 11

Product Design Sensors Processing circuit Warning system 12

Sensors  Wide 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 Sound  Costly, narrow angle, range issues 13

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

Sensors  Supposed to work up to 2.5m  Reliable results at 1.5m to 2.0m  Still works for most vehicles in the parallel lane 15
