GAR | GFV-Session 11

Revised proposal prepared by the GRVA secretary pursuant to discussions during the 15th session to clarify a logical cascade of actions regarding activation of ACSF B1 and C and the indication on when the vehicle has entered an eligible road based on the following justification:

When the same means is used by the driver to simultaneously activate the Automatically Commanded Steering Function of Category B1 (ACSF B1) and of Category C (ACSF C), both functions switch to standby mode when the vehicle enters an ACSF C eligible road. But if the road is non-eligible to ACSF C, then only the ACSF B1 is activated.
With the current text of the regulation, once the vehicle moves to an ACSF C eligible road, the driver must operate again the means to activate the ACSF C. This second deliberate action is confusing for the driver since it makes the manipulation more complex. The current wording discourages most drivers from using this assistance function.
The proposed wording permits the following, logical, cascade of actions:
1. The driver has done a deliberate action to activate ACSF B1 and ACSF C (on a non-eligible road); then
2. He drives into an eligible road, and is clearly informed thereof; then
3. He initiates a lane change procedure by activating e.g. the direction indicator.
This amendment further clarifies the requirement on the indication of when the vehicle enters an eligible road. It gives some examples of the type of indication to be given to the driver, e.g. additional popup or blinking indication, without being design restrictive.
A dedicated status indication of an ACSF C off-mode is by nature already different from the standby or active indication. Therefore, the driver is already sufficiently informed on a potential status change.
Regarding paragraph 5.6.4.2.3.: While entering the eligible road, the driver may be distracted or annoyed by this “prominent” indication. His attention resources shall be totally available during this phase. So the system would switch automatically to standby mode when fulfilling these two conditions: reaching an eligible and regular lane of travel. This second condition may be fulfilled for example by implementing a suitable time delay or by a direct verification of the lane of travel. These criteria should be explained, agreed between the technical service and the vehicle manufacturer.
