6.2.2 Criterion (2): RSE deactivation
When the RSE operator or the automatic system turns RSE off to discontinue the system due to failuresand maintenance, etc., it becomes inactive.
6.2.3 Criterion (3): OBE activation
The OBE becomes active when the accessory /ignition switch is turned on. In systems with an optionalON/OFF switch, the OBE becomes active when this switch is turned on.
lt might also transition to the active state again when a failure period ends.
6.2.4 Criterion (4): OBE deactivation
The OBE becomes inactive when the accessory/ignition switch is turned off or during failure periods.In systems with an optional ON/OFF switch, the OBE becomes inactive when this switch is turned off.
6.2.5 Class l criterion (5): Warning activation
6.2.5 Class l criterion (5): Warning activation
For the warning in Class Il, the warning shall be given when passing the area or time in which warningsare required based on the reception of information from RSE. The warning decision depends on thecriteria specified in 6.5.3.
6.2.6 Class ll criterion(6): Warning deactivation
The warning shall be ended when passing the stop line or after the warning criteria are no longer met,for example, because the vehicle has decelerated so that it is no longer in danger of violation.The position of the stop line is contained in the message sent by the RSE or stored in the in-vehicle map database.
