Driver initiated transition demand and system reaction
OICA proposal on how a transition demand may be initiated by the driver and how the system will react on it

2. Driver initiated transition demand

Driver initiated transition demand
Assumptions
This document discusses a transition demand that is initiated by the sriver and not by the system
Another document may be created for the system initiated transition demand

3. Driver initiated transition demand
Jan Lühmann
Driver initiated transition demand
Which action of the driver is initiating a transition demand?
Intentional driver input
Tbd. By Industry
Vehicle reaction
Residual system control
Lateral
Vehicle reacts lateral
Yes
Longitudinal movement is controlled by system No
Longitudinal
Vehicle reacts on brake.
Vehicle reacts on kickdown.
Vehicle optionally reacts on
Accelerator (declared by manufacturer).
Yes
Lateral movement is controlled by system No
Control element
No reaction
due to no lateral or
longitudinal driver input
Yes
Longitudinal and Lateral movement is controlled by system No
Transition demand
Continue function

4. Driver initiated transition demand
Jan Lühmann
Driver initiated transition demand
How does the system react on a driver initiated transition demand?
Transition demand
(system OR driver initiated)
Confirmation by
system that driver is
looking at the road
Longitudinal and lateral movement is controlled by system No
Yes No No No
TD time
expired?
Is driver giving second input?
Is driver
holding the steering
wheel?
Confirmation by driver No
Yes
Yes
Yes
Yes
Execute MRM
Driver has manual control
