ONE. SAE International has a formal classification system for autonomous vehicles, ranging from level 0 (not automated) to level 5 (fully automated). Briefly describe each of the levels.

  1. no automation: no vehicle control but automated system issues warning.
  2. Driver assistance (hands on): Driver should control vehicles, but automated system sometimes can play a role. For example, ABS system.
  3. Partial automation (hands off): The automated system takes full control of the vehicle
  4. Conditional automation: The driver can safely turn their attention away from the driving tasks, for example, driver can watch movie or play cellphone in the vehicles.
  5. High automation: no driver attention is ever required for safety, for example, driver can sleep in the vehicle. (steering wheel)
  6. Full automation: Driver didn’t need to stay in the vehicles, it can make its own decisions. (No steering wheel)

TWO. Use the internet to find at least two examples of autonomous vehicles that already exist. Which companies/universities/groups are they from? What autonomous behaviour do they exhibit (i.e., can parallel park itself, can drive itself)? How have they been tested?

1.    Tesla model s (auto pilot), it comes from America company, called Tesla. While the driver releases the steering wheel with both hands, the Model S can continue to travel along the driveway. The vehicle speed is automatically reduced when the vehicle is present in the front to ensure a safe distance, or even automatically.They tested on the road. The driver sit in the vehicle and he didn’t touch the steering wheel, just that the drive by its own.

2.Google driverless car, it comes from American company, called google. The most powerful place about google driverless car is machine learning. It can drive to his own self, and didn’t need any driver sit in the car. They tested their google driverless car near their headquarters. There are no driver in the vehicle, and they tested perfectly.

THREE.  Consider the SAE classifications from the question 1. At which level would each of the vehicles discussed in question 2 be? Provide rationale for your decisions.

I think tesla model s is about level 3 of the SAE. There is a news in US that one people was killed because of the accident driving the tesla vehicle. He slept on the car when he was on the highway, but when the Tesla car drive near the truck, the truck didn’t closed its back door, the model s could’t determine what it was, and drove into the truck. Above the news I mentioned that we still need to concentrate driving the car and the car isn’t smart enough to pull away all of the problems. So I grade level 3 to Tesla model s.

FOUR. Please state at least 3 possible applications for autonomous vehicles, and why they would be beneficial for those applications.

1.Robot taxi, If there is robot taxi in the future, the company of taxi can saved huge money about manpower. When we want to go anywhere, we just need to take out our smartphone, and click the nearest taxi from us, robot taxi will be more safe than the taxi nowadays.

2.IOV (internet of vehicle), IOV can combined people, cars, roads and the environment of technology, we can achieve traffic accident , electronic charges, remote monitoring, navigation route planning, vehicle anti-theft and other functions.

3.Disabled (physically challenged) autonomous vehicle, people that have some physically challenged or visually challenged can’t drive the car nowadays, but in the future, this application can surely help them relieve inconvenience driving cars. What they need is to set up the destination and they can enjoy the trip easier.
