Human driver monitor the environment
Level 0: Driver needs to always monitor the drive, no system intervention.
Level 1: The system can provide some assist to the driver by controlling either the acceleration/deceleration or steering.
Level 2: System can do both acceleration and steering at the same time, but the driver still need to always pay attention the drive to regain control at any time immediately.
System monitor the environment
Level 3: System can determine the driving environment such like recognize the vehicles, road, sign, people…etc. Human need to respond to every situation to make system perform the action.
Level 4: Built on the base of Level 3. Human no longer need to answer all the system requests. Only in some situations.
Level 5: No steering wheel, no pedal, no break. System take care all tasks or even better than human.
Tesla model S,model X, model 3
On-ramp to off-ramp: The vehicle will determine when to enter/leave when you reach the exit on the freeway. After depart the freeway, the car will return the control. So far, Tesla has acquire 47 million miles driving data on autopilot.
WAYMO —– Google
Fully self driving. Predict the behavior of not only the person, but of all the road users around. 2 million miles of real word experience.
hardware 1: Level 2,3 (2014)
Hardware 2: Level 3,4 (2016)
Both model can recognize object.
For hardware 1, the vehicles will need lots of human responds to perform the next action. For example, in hardware 1, the car will not change the lane until the driver want it. But in hardware 2, the car can done all by itself for a faster lane and without driver’s judgement nor input.
Level 4 to 5
It doesn’t has any steering wheel, pedal or break. Just like the description of SAE International of autonomous vehicles. Although it can’t perform it self-driving under high speed. It seems like the closest to fully automation.
Find parking space automatically:
There isn’t alway has parking space available when you want to get of the vehicle. If the car can self drive it self until it find a parking space after we get off the car, it will help us save up more time.
If the system can predict accident by any kind of omen, it can really reduce the chance of second time car crash or even help passengers avoid the car crash that just happen in front of them.
Control the car via mobile phone, but it actually just for use to give command for direction or adjust speed. The driving process are still automatic.
Passengers body condition monitor:
If people on the vehicle have some symptoms, system can quickly detect and ask for help. If the passenger black out, system will navigate the car to the closest medical facilities.
