Adaptive vehicle control system
A vehicle system having processors configured to determine regions of a trip where the vehicle system is permitted for a first mode of control. The permissible regions of the trip are determined based on one or more of parameters of a route, a trend of operating parameters of the vehicle system, or a trip plan that designates one or more operational settings of the vehicle system at different locations, different times, or different distances along a route. The processors also are configured to control transition of the vehicle system between a second mode of control and the second mode of control in the regions by alerting an operator of the vehicle system, automatically switching between the modes of control, or modifying conditions on which the transition occur.
