2.3.4.3 The system actively changes lanes
(1) Lane change demand input
When the NOA function is activated, the system receives the driver's request or obtains the lane change demand based on the navigation guidance information and road environment information, including the lane change demand of the navigation guidance route and the intelligent avoidance lane change demand.
Navigation guidance lane change requirements
The active lane change in the navigation guidance mode includes entering the main road from the ramp on the expressway, choosing to change lanes in advance at the branch road of the main road, and cutting off the ramp from the main road when exiting the expressway. The operation logic diagram of each working condition is as follows:

Scenario 1: The ramp merges into the main road
Under the NOA function, according to the navigation guidance, it is necessary to merge into the main road at the entrance of the ramp ahead.
Processing strategy:
