DELPHI DRIVE SAFE PRESENTED BY TEAM 5 LUKE ALLEN, PAUL CHICHURA, RAJA SURYADEVARA, ANDREZ GONZALEZ DIRECTED BY PROFESSOR JUNFENG MA DEC

BACKGROUND INFORMATION In 2012, 10,322 people were killed in alcohol-impaired driving crashes, accounting for nearly one-third (31%) of all traffic-related deaths in the United States. Nearly 1.3 million people die in road crashes each year, on average 3,287 deaths a day. An additional million are injured or disabled. More than half of all road traffic deaths occur among young adults ages Each year nearly 400,000 people under 25 die on the world's roads, on average over 1,000 a day.

WHY DO THIS PROJECT Delphi is a leading global supplier of technologies for the automotive and commercial markets. To minimize the impact on the environment. To provide safer technology to decrease the number of accidents.

MISSION STATEMENT We hope this design will let the drivers, the passengers around the world and even us have a safer ride and decrease the number of road accidents. As we all love the nature we are also trying not to cause any damage to the environment by using recyclable material.

The Design Process

LISTENING TO THE CUSTOMER Needs of the customers were obtained through an online survey we created and internal discussion within the group Better understand what customer wants in product Helps us to make a viable product for the market

SURVEY RESULTS: DRIVING WHILE TIRED Part of our survey had questions on driving while tired Out of the 30 people who responded: 47% said that they are likely to drive while tired 13% said that they have fallen asleep at the wheel before 80% considered driving while tired to be a legitimate concern of safety for themselves and others

SURVEY RESULTS: DRIVING WHILE INTOXICATED Another part of our survey had questions on drunk driving 10% said that they are likely to drive while under the influence of alcohol 30% said that they have driven while under the influence 93% considered driving under the influence to be a legitimate safety concern for themselves and others

SURVEY RESULTS: OTHER CONCERNS We asked respondents to give us other concerns for safety while driving Marijuana and general distractions were most commonly stated When asked how tiredness could be alleviated while driving: 62% said that loud music would help 76% said caffeine would help 55% said cold air would help 79% felt that a device in the steering wheel that monitors heart rate would not be invasive

DETERMINING DESIGN ATTRIBUTES Using the data from our survey and internal group discussions, we came up with 4 “top-layer” attributes for our safety system Sensing method, response, problems detectable, and level of driver interaction Next, we created multiple second-layer attributes under each first-layer attribute

GETTING THE MOST IMPORTANT NEEDS We came up with many customer needs Wanted to get the top 10, however “extraneous needs,” or unviable design choices due to economic constraints, etc. must be taken out To accomplish this, we used the analytical hierarchy process (AHP)

CUSTOMER NEEDS HIERARCHY 1) Ease of Use (0.118) 1.1) Intuitive (0.063, 0.538) 1.2) Visible (0.015, 0.128) 1.3) Simple (0.039, 0.333) 2) Connected (0.324) 2.1) Adaptive (0.065, 0.200) 2.2) Sensitive (0.081, 0.250) 2.3) Accurate (0.097, 0.300) 2.4) Informative (0.020, 0.063) 2.5) Personal (0.024, 0.075) 2.6) Customizable (0.036, 0.113) 3) Safe (0.441) 3.1) Responsive (0.086, 0.194) 3.2) Quick (0.037, 0.083) 3.3) Attentive (0.135, 0.306) 3.4) Reliable (0.184, 0.417) 4) User-Friendly (0.118) 4.1) Affordable (0.007, 0.062) 4.2) Universal (0.006, 0.052) 4.3) Private (0.025, 0.213) 4.4) Comfortable (0.024, 0.204) 4.5) Compact (0.015, 0.128) 4.6) Unobtrusive (0.028, 0.242) 4.7) Efficient (0.012, 0.100)

OBTAINING THE TOP 10 NEEDS We used an AHP table to determine the top 10 initial second-layer attributes These 10 were selected based on their weightings After this, we put these 10 into an AHP table and determined the top 5 second-layer attributes

TOP 5 ATTRIBUTES Here are the top 5 attributes and their weightings

DESIGN CONCEPTS Now that we got the top 5 attributes, we had to think of some concepts that might be present in the final design To do this, we went through the process of concept generation

WHAT IS THE PROBLEM? In concept generation, it was important to remind ourselves of what the problem we are trying to solve is Doing this focused the group on creating viable concepts that would be pertinent to the desired design For us, the problem was making a viable safety system for automobiles

SEARCHING EXTERNALLY For possible inspiration on a design we could make, the group read literature on heart monitors, how the heart’s beat changes when tired, breathalyzers, etc. The group also read up on patents that are relevant to our ideas, as to make sure we were not infringing on others’ property

SEARCHING INTERNALLY After reading a lot of material, we discussed internally as a group as to what material was useful and could help us make a good design How could these ideas be implemented into the concepts we had? It was important to have open discussion within the group so that all possible ideas were heard and considered

AFTER CONCEPTUALIZING When we had our concepts, it was wise to classify them This was done to make the concept selection process easier To accomplish this, we used a classification tree and concept selection tables

Concept Selection

FACTS AND STATISTICS

- Underreported - No Tests - It is hard for Cops to notice drowsiness in drivers % of all crashes.

DIFFICULTIES??

WHAT WE HOPE TO ACHIEVE: - Safety - To Meet Delphi’s Goals - Prevent Drowsiness Accidents Rates.

THANK YOU!!
