Here is some of the relevant parts of the document :
Driver availability recognition system
2.11 ALKS is required to have a ‘driver availability recognition system’ that detects if the
driver is present in a driving position with their safety belt fastened and is available to
take over the driving task. If the driver is detected not to be in the seat for more than
1 second or if their safety belt is unbuckled, the system will issue a transition
demand.
2.12 The system must monitor the driver to detect if they are available and in a position to
respond to a transition demand. Driver availability must be determined by at least
two criteria that are checked at least every 30 seconds. Examples of criteria include:
• Input to driver-exclusive vehicle controls;
• Eye blinking;
• Eye closure;
• Conscious head or body movements.
2.13 As soon as the driver is unavailable, the system will provide a distinctive warning. If
the driver fails to demonstrate that they are available within 15 seconds, the system
will issue a transition demand. However, if the driver successfully demonstrates that
they are available, on the basis of criteria above, the ALKS will continue to operate.
System Override & Driver Attentiveness
2.14 The driver can “override” either the lateral or longitudinal control of the vehicle,
subject to measures put in place to protect against unintentional inputs. The
manufacturer must create reasonable thresholds designed to prevent unintentional
inputs. Inputs above these thresholds are considered to be overrides. During an
override up until the point of deactivation, the ALKS will continue to operate and
control the other aspects of the dynamic driving task. In this situation, the ALKS is
considered to be in control of the vehicle until the system deactivates and control is
resumed by the driver.
2.15 Measures used to protect against unintentional steering inputs are varied according
to driver attentiveness. The driver is deemed to be attentive if at least one of the
following criteria is met:
• Driver gaze direction is confirmed as primarily looking at the road ahead;
• Driver gaze direction is confirmed as looking at the rear-view mirrors;
• Driver head movement is confirmed as primarily directed towards the driving task;
• Alternative criteria declared by the manufacturer have been met. A manufacturer
may declare alternative criteria for determining driver attentiveness provided this
is supported by evidence.
2.16 An override input to the accelerator or brake pedal will result in a transition demand
being issued.
