Lecture 6 - Automated Vehicles Flashcards
Level 0 car
There are no autonomous features
Level 1 car
These cars can handle one task at a time, automatic braking
Level 2 car
These cars would have at least two automated functions
Level 3
These cars handle “dynamic driving tasks” but might still need intervention
Level 4 car
These cars are officially driverless in certain environments
Level 5 car
These cars can operate entirely on their own without any driver present
Afraid of riding a fully autonomous vehicle statistics
2017: 63%
2018: 73%
2019: 71%
2020: 86% (of which 32% “unsure”)
Outsized reactions
Outsized reactions in the face of inevitable accidents
“They said they need real-world examples, but I don’t want to be their real-world mistake”
Human Machine Interface
- Vehicle and human can be seen as a
joint cognitive system - The HMI provides continuous
interaction between human and vehicle
3 main challenges HMI
- Minimize mode errors
- Stimulate appropriate level of attention
and intervention - Minimize automation surprises
Minimise mode errors
Can the automated system…
* Handle longitudinal and lateral control
* Manoeuvre in the current environment and situation (e.g. handle a roundabout)?
* Perform strategic aspects of driving (e.g switch lanes or change route)?
Stimulate appropriate levels of attention and intervention
Level 2: Driver attention to the road needs to be as high as during manual driving
The higher the reliability of the system, the lower will be the attention of the driver and the higher the impact of a failure
Minimize automation surprises
Two types:
* Absence of expected action
* Presence of unexpected action
eHMI (external-Human Machine Interface) - main challenges
- Communication
- Scalability
- Colour
eHMI Communication - instruction or intention?
Intention
