3 Executive Summary ii All-terrain vehicle (ATV) sales and subsequent recreational riding has significantly increased in North American market. The ATV cannot claim a history as long as the motorcycle, although it rouses the passion of the owners and riders all over the world. ATV was built and sold by Royal Enfield in 1893, and in 2012, more than 225,244 ATVs were sold in US. More and more people would like to drive the ATVs. However, safety has been a major issue with ATVs due to great number of deaths and injuries with them. According to the C o n s u m e r P r o d u c t S a f e t y Commission, in 2013, ATVs were responsible for 125,500 injuries in US and rollover is the most seen accident associated with ATVs. ATV usually weight more than 700 pounds, and it is quite dangerous when it rollovers. Therefore, a protection system to prevent rollover and decrease the damage is needed. This document proposes developing a device that will give warning to rider when the ATV reaches a dangerous angle and decrease the damage as much as possible if the rollover really happens. When the ATV reaches a dangerous angle of roll, the system will use red warning light and alarm to remind the rider. If the ATV exceed the dangerous angle, the automatic protection system will be activated. Our system uses a extended bar to create a safe-triangle area when rollover happens. consists of five fourth year Simon Fraser University engineering students with experience in circuit design, mechanical design and software programming. We expect researching, designing, constructing and testing our device takes about 13 weeks from January And the budget of the project is set at $983 which will obtained from ESSEF.

6 Proposal for ATVs Automatic Protection System 1 1. Introduction Have you tried driving a ATV in a wild open field? The smell of grass, sound of wind, view of boundlessness. With some small hills and slope, the feeling can be more exciting than roller coaster. It is a must-try adventure. However, excitement includes risk. As people drive less cautious with ATV, accidents can easily happen, especially when driving on an incline. Driver can hardly tell how much the vehicle has been tilted by vision and when the vehicle is going to flip. It is not a good experience when you cannot move because the whole vehicle is over your body. Therefore, a protection system is necessary for ATV. Existing solution is to install a long protection bar at the end of the vehicle to create a safe-triangle when the vehicle rolls over. However, this protection bar at the end of the vehicle is banned in North America market because it may alter the centre of gravity of the vehicle or hooked on roadblocks. That is the reason we,, are looking for a solution to provide safety while keeping the fun of driving. The purpose of this project is to remind the driver when the vehicle reaches a dangerous angle and protect the driver from being crushed by the machine, called Automatic Protection System for ATV. This system should not disrupt the attention to the driver. Any ATV can use this model to improve its safety performance. Automatic Protection System for ATV consists of two level sensors. One connects to a buzzer and LED light to notify the driver to mind the angle. Another one acts as a trigger to a protection bar that can be ejected when the vehicle is about to roll over. Using this system, the driver no longer needs to worry about the slope of the ground and injury caused by rolling over of ATV can be greatly minimized. is found by five motivated 4th year engineering students to provide solutions to safety issues and to produce it with a cost that is competitive within the existing market. This proposal will document the overview of our product, possible design considerations, proposed solution, scheduled planning for our workload, and allocation of funding.

7 ! Proposal for ATVs Automatic Protection System 2 2. System Overview Figures 1 and 2 show the basic function of our automatic protection system. The system is to prevent the roll-over of the vehicle. We have a electric level sensor to detect the angle of roll and send the signal to micro-controller during driving. The controller will adjust the signal to determine if the vehicle is in safety environment. When the angle of roll and vehicle is approaching to dangerous position, the controller will operate the alarm and light system. When the vehicle is about to roll over, the protection system will be triggered aromatically. Figure 1. System Overview

9 Proposal for ATVs Automatic Protection System 4 3. Possible Design Solutions The goal of this project is to prevent rollover of ATV and provides necessary protection to driver. There are many different solutions to solve these problems. Some possible solutions listing below are partially used in our design. a. Helmet alarm system The alarm system is decided to be placed inside the driver s helmet at the beginning of our design. However, there are two problems came out during late on process. Firstly, the structure of the helmet will be changed if we assemble the alarm system inside. We cannot prove that the new structure of helmet can still provide enough protection for driver. Secondly, the wireless signal transfer is hard to achieve due to the limitation of time. b. Alarm system with LCD screen display A LCD screen display will help driver to know the inclination of the vehicle. The disadvantage of this system is that the display may distract the driver. Just like the prohibition of call during driving the car, we do not want our system bothering the driver. c. Protection system The protection system can only be triggered when the vehicle is rolling over. The roll-bar placed at the back of vehicle will shoot its inner tube to extend the height of roll-bar. The inner tube cannot go backward after shot, unless the driver reset the system manually. Larger safety space can be created for driver by higher roll-bar. Also, the inactive mode of our protection system will not interfere driving.

10 Proposal for ATVs Automatic Protection System 5 4. Proposed Design Solution Our proposed solution is to build a module that combine the alarm system and protection system. The new system will warn the driver for dangerous situation and protect the driver for emergency situation. This system would be very useful for drivers to improve their driving performance and save their lifes from accident. There are at least two advantages we can made for public through out our design. First, the alarm and light system will help the driver to avoid the accident. Second, the protection system will give a chance to save driver s life. Compare with other solutions we can find on the market, our solution is the only one which contains both abilities of alarm and protection. The main constraints for this project are the limitations of time and funding. We have only 3 months for designing, assembling and testing. Moreover we must consider the funding from ESSEF. We can only make the model for our design which could achieve for design purpose. The strength of our roll-bar may not fit the real safety requirement. Thus, we may simulate our design just on a model. If more time and funding are allowed for this project, we can add more features on the system. A data collection program would collects the driving information to help driver manage the plan. The user interface would allow users to create their own profile. Different drivers will have different opinions of dangerous due to their skills and experiences. The separated level to warning would significantly improve our system s performance.

Sources of Information In order to successfully implement our design into real product, we will obtain different resources including internet, textbooks, manufacturers component specification sheets, professors / TAs with experience in different aspects and friends who were working on signal processing and transmitting company for co-op. The core of our project design is to convert the signal we received from the electric level sensor into voltage difference and send it to the micro-controller. Then based on our programmed conditions to select the destination for the next step launching the protection bar, activating buzzer and indicting via LED lights. With that in our head, we consulted the micro-controller s manufacturer as well as some post-graduate students and came up with a basic picture for solving this problem. We believe that with the knowledge we leant from real time and embedded systems, digital systems design and micro-controller interfacing and assembly-language programming, we will be able to overcome all the difficulties for rest of the software design. Finally, the teaching assistants will help us with their skills and experiences for our hardware design. For example, what kind of steel/alloy should we choose to give us better hardness without affecting ATVs performance or how to lock the protection bar so that it can be firm and stable during flipping-over. Their advices will be necessary and valuable.
