When the RSE operator or the automatic system turns RSE off to discontinue the system due to failures and maintenance, etc., it becomes inactive.
6.2.3 Criterion (3): OHE activation
The OBE becomes active when the accessory/ignition switch is turned on. In systems with an optional ON/OFF switch, the ORE hecomec active when this switch is turned on.
It might also transition to the active state again when a failure period ends.
6.2.4 Criterion (4): OBE deactivation
The ORE 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 II criterion (5): Warning activation
For the warning in Class II. the warning shall be given when passing the area or time In which warnings are required based on the reception of information from RSE. The warning decision depends on the criteria specified in
6.2.6 Class II 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 iris 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.
6.3 Functional requirements of OBE
6.3.1 Acquisition of travel direction
The direction oltravel of the vehicle shall be acquired using a position-detection function such as global navigation satellite systems (GNSS) or information provided from the RSE.
6.32 Acquisition of vehicle position
The position of the vehicle shall be acquired using a position-detection function such as GNSS or intormation provided from the RSE.
6.2.3 Criterion (3): OHE activation
The OBE becomes active when the accessory/ignition switch is turned on. In systems with an optional ON/OFF switch, the ORE hecomec active when this switch is turned on.
It might also transition to the active state again when a failure period ends.
6.2.4 Criterion (4): OBE deactivation
The ORE 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 II criterion (5): Warning activation
For the warning in Class II. the warning shall be given when passing the area or time In which warnings are required based on the reception of information from RSE. The warning decision depends on the criteria specified in
