Proposal to reduce the maximum delay for warning a driver of prolonged ‘hands-off driving’ as a function of vehicle speed. The current calculation is based upon 30 seconds (i.e., t(s) = 30(s) * 130/V, where V is the speed of the vehicle in km/h at the time when the system has detected that the driver is no longer holding the steering control). Korea proposes 15 seconds. Additionally t would not be permitted to be greater than 180 seconds.

Latest version of the amendment proposed in document GRRF/2016/45 as Option 3 and under discussion within the ACSF informal group

UN R79 amendment proposal to introduce provisions for “corrective steering functions” as a separate category of steering system from automatically commanded steering functions (ACSF). Corrective Steering Function (CSF) means the control function within an electronic control system whereby, for a limited duration, changes to the steering angle of one or more wheels may result from the automatic evaluation of signals initiated on-board the vehicle.
