VEHICLE CONTROLLER AND METHOD FOR CONTROLLING VEHICLE

A vehicle controller for automated driving control of a vehicle in traffic congestion includes a processor configured to sense at least one another vehicle around the vehicle, based on a sensor signal obtained by a sensor for sensing a situation around the vehicle, the sensor being mounted on the vehicle; calculate a motion value indicating motion of the sensed at least one other vehicle; determine, when the motion value satisfies a congestion relief condition, that congestion is relieved around the vehicle; and set the congestion relief condition, based on road environment information indicating environment of a road around the vehicle.
