1. A vehicle system for determining a recommended lane for an own vehicle in a case where the own vehicle travels on a road having a plurality of lanes on one lateral side thereof, the vehicle system comprising:
a controller configured to communicate with a map server that stores map information including traffic state information on each lane;
a vehicle position acquiring device configured to acquire own vehicle position information for determining the lane in which the own vehicle is traveling and transmit the own vehicle position information to the controller; and
a navigation device,
wherein the controller includes:
a vehicle position determining unit configured to determine the lane in which the own vehicle is traveling based on the own vehicle position information;
a recommended lane determining unit configured to determine the recommended lane; and
a storage unit configured to store preference of an occupant including preference for a timing of a lane change of the occupant, and
the recommended lane determining unit is configured to set a priority of each lane based on the map information,
determine the lane having a highest priority as the recommended lane, and
adjust a switching point of the recommended lane according to the preference stored in the storage unit,
wherein the recommended lane determining unit is configured to determine an actual start position of a lane change process during manual driving and to calculate a difference between the actual start position of the lane change process during manual driving in which the navigation device guides the occupant to move the own vehicle to the recommended lane and a position to be set to the switching point during autonomous driving,
the difference relates to the preference,
the storage unit is configured to store the difference, and
during the manual driving, the recommended lane determining unit shifts the switching point from the position to be set to the switching point during the autonomous driving by a distance corresponding to a representative value of the difference.
