Safety evaluation method of human-machine interaction in automobile intelligent cockpit
1 Scope
This standard specifies the evaluation method of the impact of distraction caused by the interaction between the driver and the touch screen of the automobile intelligent cockpit on the driving safety. This standard is applicable to the evaluation of driving interaction safety in driving secondary tasks during manual driving.
It is applicable to various forms of central console screens associated through visual/touch interaction.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
driving interaction safety
risk for driving safety caused by human-machine interaction behavior
3.2
driving secondary task
touch control interaction tasks unrelated or not directly related to driving in the driving process, compared with the main driving tasks such as controlling vehicles and monitoring road conditions
3.3
visual distraction
process in which the driver's ability to perceive the environment decreases when the sight is off the road due to visual secondary task
3.4
operational distractions
process in which the driver's ability to perceive the environment decreases due to the resource occupation of hands and feet caused by the operation secondary task
3.5
cognitive distraction
process in which the driver's ability to perceive the environment decreases when his/her awareness is off the road surface caused by the cognition secondary task
