Cruise Control
.Cruise control is a system that automatically controls the speed of a motor vehicle. The system takes over the throttle of the car to maintain a steady speed as set by the driver.
Need for Cruise Control
.Reduce the risk of accidents,
.Improve safety,
.Increase capacity,
.Reduce fuel consumption
.Enhance overall comfort and performance for drivers.
Adaptive Cruise Control
.Autonomous cruise control is an optional cruise control system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead.

Ultimate Goal of Paper
.This paper proposes more accurate methods of detecting the preceding vehicle by radar while cornering, with consideration for the vehicle sideslip angle, and also of controlling the distance between vehicles.
.By making full use of the proposed identification logic for preceding vehicles and path estimation logic, an improvement in driving stability was achieved.

.For the acceleration/deceleration performance, which has a large effect on occupant comfort, when the lane was changed during tracking and the preceding vehicle sped up, the acceleration performance satisfied the need for a smooth feeling of acceleration with a short response delay. .Conversely, when the driver’s vehicle caught up with the preceding vehicle, a smooth and comfortable feeling of deceleration was achieved.

If the autonomous vehicle possessed the predisposition to drive straight after completing a turn, the vehicle should not have outside influences affect its decision. By doing so,

Human drivers have instincts that cannot be duplicated by technology, but by that same token human error is not a part of a self-driving car. In addition, we also need to take into consideration the transition period, when there are self-driving cars as well as human drivers on the road. Humans can notice the other drivers physically signal to go-ahead, when at a four way stop sign or; offer an opening for the merging lane. This is an example of what human interaction is capable of, that self-driving cars will need to calculate in order to
People don’t know what to think about driverless cars. There are many debates on whether or not americans are ready for this kind of technology. Also people don’t know how safe they are or if people know enough about the advanced technology. People are already distracted while driving a driverless car could create more new problems than it fixes. Driverless cars are not ready to be on the road.
We were so excited that we came up with a flavor to submit! We asked our parents
Driving tends to be the one thing almost everyone in their life gets to do at one point in their life. Nowadays you can even take driving classes in high school. The teacher’s teaching driving Drivers Ed. are also required to teach you the signs of the road, the rules of the road, all the different kinds of lines, and what you should do in critical situations. The driving classes also require you to have behind the wheel experience with your instructor who will then see if you can drive in the real world. If you do not pass the instructor’s class then you cannot go get your license. Now, just because many students pass the class and also the driving portion does not mean that they will pass the Department of Motor Vehicles (DMV) driving test which is generally tends to be harder.
Toyota failed to address complaints involving impulsive unintentional acceleration starting in 2002. During this time, a new electronic throttle control system replaced the standard equipment in Toyota vehicles (Gorman, 2010). According to Steve Gorman, Toyota insists that the defective vehicles sped out of control because of the floor mats and sticking gas pedals. Both issues were addressed by safety recalls. Gorman states that many unintended acceleration cases stem from driver inaccuracy (Gorman, 2010).
We were shown to a large table that could seat the twelve of us then we all ordered warm bowls of soup. The waiters and waitresses weren’t trained to do this job, they were just ski instructors that took on an extra job during meal times. We had lovely warm soup and the best chips (or fries to some of you) that I had ever tasted. The chips soon became a favorite and I ordered it with whatever I had every night for the rest of our time there.
“I wonder how many different kinds there are,” Abby says while basically drooling over the glass, covering the tiny, yummy treats covered in frosting. We tell them our order, Julia orders chocolate with chocolate frosting. My mom orders red velvet with cream cheese frosting. Abby orders a strawberry cupcake, and I order a vanilla bean cupcake.
Due to many deaths by motor vehicles The National Highway Traffic Safety Administration legislated a code for Motor Vehicle Safety. This was developed to issue Federal Motor Vehicle Safety Standards and Regulations (FMVSS) that requires motor vehicle and equipment items manufacturers must conform and certify compliance. The Federal Safety standards are implemented for minimum safety performance requirements for motor vehicles and items of motor vehicle equipment. The main reason for the specific regulations is to protect civilians from death or injury; also against unreasonable risk of crashes resulting from bad designs, performance, or construction of motor vehicles.
Since there was no parking at the restaurant, we had to walk there, which was quite relaxing in my opinion. Once we got there, the service was great. They made sure everything was to perfection and we enjoyed our thirty minutes there. Once we got back from the restaurant, we sat and watched some soccer because that was the only channel the TV could pick up. And then we went to bed, awaiting our time to tour the city.
According to the National Safety Counsel’s 2017 Injury Fact Report, nearly 38,000 people in the United States died due to vehicle crashes and more than 4 million people sustained injuries that required medical treatment in 2015.
