Proposal to clarify the logical cascade of actions relative to ACSF B1 and ACSF C systems:
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 actually discourages most drivers from using this assistance function.
The proposed wording permits the following, logical, cascade of actions: - The driver has done a deliberate action to activate ACSF B1 and ACSF C (on a non-eligible road); then
- He drives into an eligible road, and is clearly informed thereof; then
- He initiates a lane change procedure by activating e.g. the direction indicator.
