Sensors

Cassandra, Gayathri, Rohan, Patrick

- Many distractions while driving- Want to dramatically reduce

accidents that occur- Try to figure out ways to change

a vehicle to make it safer

Background

- Our primary concern: safety of drivers and those nearby

- Human error with driving happens so frequently, we need to focus on how we can manage and control this situation to prevent fatalities

Mission

- We wanted to create structured sensors

to ensure driver is at ease and safe, as

well as to ensure the safety of others.

- We want to provide an efficient and

reliable solution to increase safety on the

roads.

Meeting Our Customer Needs

Patents:❖Based on a toy car model, it connects the sensor with the driving circuit. Whenever there is an obstacle in the way, the car automatically comes to a hault.

Exploration of Ideas

❖ Car reverse radar that automatically modifies the sensor scanning range and method of the same. It can determine the distance between the car and obstacles behind the rear of the vehicle.

Exploration of Ideas Continued

❖ Obstacle detection system that alerts the driver of a vehicle when there is an obstacle in a the track of the vehicle. This system incorporates a video camera for the system’s sensor.

Exploration of Ideas Continued

❖ Automatic parking device for automobile: A device is mounted onto the car to help the driver parallel park more accurately. The device determines distance from the curb, when to turn the wheel to get into the space and how much room the car will have in front of as well as behind it.

Exploration of Ideas Continued

❖ Smart blind spot sensor with object ranging: a radar system for sensing the presence of obstacles in the “blind spots” that every vehicle has. It transmits a multi-frequency radio signal directed at blind spots of the vehicle. The signal is reflected off of obstacles that are in the blind spot direction.

Exploration of Ideas Continued

❖ Sleep detector/driver alert-compact storage attached around the rearview mirror & dash; detects early impending sleep via body temperature & breathing patterns; alerts driver when falling asleep through noise and words

Exploration of Ideas Continued

❖ Parking Assist system- detects when vehicle has passed an open area to park; emits radio/ultrasonic waves; determines distance between cars and between curb; gives direction when to turn wheel, etc.

Exploration of Ideas Continued

❖ Lane Change: assist system to reduce effort and stress; assesses situation; gives options to pass on road; estimates different driving alternatives according to signals from a main vehicle sensing device; gives driving alternatives including ones to stay in the current lane.
